Hydration: Weirder Hydras

So, other people have been writing about hydras.  Chris McDowell and Dunkey (who is, himself, a kind of hydra) in particular.  I wrote one, too.

20 Hydras (or 1 Chaos Hydra)

You can either run this as 20 different types of hydras, or as a random table for a hypothetical Chaos Hydra that has a bunch of weird heads.

A flailsnail-headed hydra is basically just a flailsnail with head regeneration and without the weird shell effects, but if it's a hammer-headed hydra, that's pretty cool.  Especially if all the heads are slamming down asynchronously.

1. Bug-eyed, frog tongue.  30' ranged attack roll, target must pass a hard (-4) Str check or be pulled into the mouth for a bite attack.
2. Rabid and albino. 2-in-6 chance to attack self.  Will attack most wounded heads in an attempt to make more heads (which is what any smart hydra would probably do).
3. Floating.  Head flies off from body and flies around like a goddam flying crocodile head.
4. Mosquito head shoots live stirges, which then collect blood and return via its ear.
5. Featureless nozzle.  Vomits piles of slippery acid, 30' cone, 1d6 damage per turn until washed off, and the acid on the ground functions like grease.
6. Flailsnail flail.  2d8 damage, -4 to hit.
7. Emaciated.  Bites for a mere 1d4 damage when attacked, but when severed, it's skin sloughs off and it fights like a giant snake for 3 rounds (screaming) before dissolving into dust (which will also be screaming if you hold it up to your ear).
8. Telekinetic.  Knows telekinesis and is strong enough to pick up people and fling them against walls.
9. Monocular.  Antimagic cone in front of head.
10. Cnidarian Hydra.  Grapples like a black tentacles spell, stings for 1d6 non-lethal damage while held.
11. Psychovampiric.  Knows vampirokinesis (save or have all of your blood sucked out of you, which then orbits the caster in a bloody halo.  The caster is paralyzed for 2 turns, and if the caster is still alive at the end of that time, the target dies from massive, postponed blood loss, and the caster heals for 2d6+2 HP.)
12. Mirror-blooded, blue-skinned.  Whenever this head takes damage, half of that damage is mirrored onto the attacker.
13. Doppleganger.  Shape-shifts its face to resemble a loved one whenever it is attacked.  You must succeed on a successful Charisma check to attack a head (failure indicates hesitation).  And if you actually cut off your mom's head (or whatever) you gain an insanity point.  The hydra is only capable of duplicating one head each time.
14. Worm.  This head burrows underground and then bursts forward to attack you with only a tiny fraction of a second forewarning, then retreats.  (Usually requires readied actions to hit.)
15. Uterine.  Launches live human infants at you like a fucking cannon.  Infant has a 10% chance to survive this, and if they survive, they will age 16 years in the first 16 days, and grow up with an irrepressible urge to be dragonslayers.  
16. Ghidorah.  This golden head shoots lightning lasers (1d6 damage, but in a straight line, save for half).  The body also has wings and is capable of flying into space.  It has a second lair on the moon with a second treasure hoard.
17. Spiral Drill.  On a hit, shield is destroyed if a save is failed.  If no shield, then armor.
18. Witch-Nymph.  Shrieking and beautiful.  On a hit, target must save vs charm person.  If there are more than one of them, a pair of them can spend a turn tying a knot in one's hair and a player must immediately save or have a limb of the hydra's choice snap.  A successful save indicates that the limb is wrenched and useless for 1d6 rounds.
19. Hammer.  Spends one turn raising itself up in the air (out of melee range) and then slams down for triple damage on the next turn.
20. Rapier-tongued.  Sword is sharp and straight like a fencing weapon.  It gets +2 to AC against swords and will duel whichever swordsman looks most proficient, to the exclusion of all others.  If there is no swordsman (or they look incompetent like NPCs) it will attack whoever looks most dangerous.  The hydra is incapable of speech, but if it is insulted wittily (DM's discretion) it will get -2 to attack for a turn.

Inversion Hydra

This is a normal-looking hydra except for the fact that it appears to be monstrously pregnant.  When it is fighting, players can feel themselves being pulled toward it's gravid belly, and call feel the pressure of amniotic fluid on their eardrums.

When the players kill the hydra, they all die and are sucked into the hydra's womb.  They then burst from the womb as an ungodly amalgam of all players (use fusion rules) with 20' necks and a bite attack for 1d6+Str.  The teeth from the severed heads then grow into lizardman warriors (twice as many as players) which try to kill the player-hydra with their own weapons (looted from the bodies).

If all of the skeletons are killed, the player-hydra will split back into it's constituent selves.  Also, they have a copy of their own corpses, which I've learned can be extremely useful.

That's a bit heavy handed, though, so ALTERNATIVELY this could be something like a vampiric hydra that bites people, tasting their blood, and then when the hydra dies, anyone who had their blood drank gets turned into the composite hydra. The hydra tries to taste everyone, of course.

ALTERNATIVELY, try to get player buy-in.  Maybe they need to all impregnate the God Egg on level 5 of the dungeon and be reborn into a glorious new reptilian body in order to access the Plane of Reptiles.  I imagine it just being like a giant, squishy egg cell.  Dudes can probably just ejaculate into it, but girls might have a harder time.  (The egg probably only needs a bit of blood to get going, but if you want to shove menstrual fluid in there, that'll work, too.)

IOUN Hydra

This is a golem-hydra.  Each head is a floating IOUN stone, about the size of your first, disconnected from the body (but incapable of getting more than 20' away).  Each gemstone is unique, and while most are spherical, all heads have different characteristics.  Each head is styled after the shape and pattern of a reptilian predator.  For example, the "viper" head is vaguely triangular and is covered in a pattern reminiscent of snake scales.

It has a spherical body that spins around like a giant top.  It is easy to track because it leaves a divot in the dust.  If it needs to go up stairs, the "heads" will serve double-duty as feet.  If it is killed, it shatters completely and leave 1d3 IOUN stones in the dust.  All of the heads shoot beams.

If a head is shattered, the shards will fall to the ground and begin to regenerate.  They have AC 10 and must take 8 damage from bludgeoning (to smash them to smithereens) and/or fire (to melt them to the floor) before the next turn, or they will regenerate into 2 new IOUN heads.

HD 2 + 2 per head AC plate Attacks (see below)
Move 12 Int 12 Mor 12

1. "Viper".  Magic stealing beam.  Save or lose your highest level spell.  The Hydra will cast that spell next turn.
2. "Constrictor". Save or be caught in a psychic vice-grip: immobilized, held 6 inches off the ground, and take increasing damage each round.  (1d6 the first round, 2d6 the second).  Treat this psychic grip as having Str 22.
3. "Frog". Teleportation to a random room in the dungeon.  (I know frogs aren't reptiles but whatever.)
4. "Toad". Save or become stricken with Umbral Toad venom.  While so affected, you take 2d6 damage every turn you are awake, but you can fall asleep whenever you wish.
5. "Caiman".  3d6 damage, and if the target fails a save, they become a magic magnet for 1 round: all spells within 40' are redirected to them as a target.
6. "Dragon".  Does 3d6 bite damage (this is still a beam of phantasmal dragon jaws) and the target must save vs dragon fear.
7. "Stegosaur".  Resonant hum.  3d6 sonic damage in a 60' line, save for half.  Targets in metal armor get a penalty to their roll equal to their armor bonus to AC, because their armor functions as a resonant tube.
8. "Lizard". Target takes 2d6 radiant damage for every eye that they have.
9. "Ankylosaur".  Target's HP is cut to half of it's current total.  If they succeed on a save, it is cut to 75% of their current total.
10. "Crocodile".  2d6 damage and the target must save, or their weapon turns into metal dust.  (Note: this stuff is highly explosive when dispersed through the air.)
11. "Komodo Dragon".  2d6 damage, then save or lose 2d6 Strength.  If you fail this save, it spawns a 1 HD homunculus in an adjacent square that is loyal to you, but completely moronic.
12. "Ichthyosaur".  Ice beam for 3d6 damage in a line.  Additionally, on the second round of combat, it will begin resonating.  As long as it is resonating, the strongest player (icthyosaur's choice) is reduced to being a copy of the weakest player (icthyosaur's choice).  Treat their stats and abilities as a mirror image.  Everything except for the inventory list, basically.  When the IOUN hydra is killed, the "weakest" player gets a bonus +1000 XP and the "strongest" player loses -1000 XP.

Beholder Hydra

This is a beholder suffering from a horrible skin disease contracted from a Hydrada.  It's central eye has turned into a Sphere of Annihilation, and each of it's minor eyestalks has grown into a biting hydra head.  The eyes cannot fire beams any more--instead, the abilities are activated on a bite.

Three Hydras

Hydrada

HD 8 AC chain Attacks (1 per head)

Move 12 Int 5 Mor 7

Regenerates 1 body HP per round

Hydradas are just hydras from the Elemental Plane of Hydras.  They are hydras with the hydra-ness turned up to 11.  They usually begin with 3 heads (2 HD each, but AC as plate, because of how quickly they whip around.)  Slashing weapons can sever heads or damage the body; other types of damage can only damage the body.  Head damage is mirrored onto the body.

Each of their bites does 1d6 damage.  If an attack does 5 or 6 damage, the target must save or a hydra head will grow from their wound on the next turn.  The head has a 10' reach, and attacks as a normal hydra would attack, with the same damage and AC.  It can be severed normally (but will regrow into two heads unless the stump is cauterized with fire or acid).  The host gets -2 to attack a hydra head growing out of their own body.  The hydra head preferentially attacks its host (biting them on the face and ears, usually).  If the hydra head reduces its own host to 0 HP, it decapitates the host.  If the host is decapitated and the hydra-head-sprouting-from-the-wound remains, two hydra heads erupt from the stump on the next turn.

Whenever hydrada blood is spilled there is a d% chance (equal to the damage taken) that a hydra head will sprout from whatever surface the blood spills on.  This head has a 20' reach and follows all the normal hydra rules.

Severed heads become 1 HD hydroids after 1 turn.  They have no neck, and can be killed like any other little critter.  However, unless they take fire or acid damage, they will regenerate to 1 HP

Whoever kills the hydra is afflicted by the hydra's death curse: all creatures will appear to be hydras for the rest of the day.  All speech sounds like hissing.  All written text appears as "hydra hydra hydra" etc.  No save.

Zoo Hydra

HD 1-20 AC chain Attacks (1 per head)

Move 12 Int 5 Mor 7

A zoo hydra is created whenever some really weird shit happens at the zoo.  The heads will regrow in 1 round unless salt or urine is applied to the stump.  It has one head for every HD.

Heads [d20, or just go down the list]

1. Crocodile - Bite 1d10, but with a -2 to hit.

2. Fox - Bite 1d4.  Every 2 turns, reroll a d20 that someone else rolls.

3. Lion - Bite 1d8.

4. Howler Monkey - Howls.  Every turn, has a 10% chance of attracting a new random encounter.

5. Giraffe - Smashes for 1d6.  Ridiculous 30' reach.

6. Wolf Skull With Glowing Red Eyes - Bites for 1d6.  Can reanimate dead things as loyal zombies, 1/turn.

7. Komodo Dragon - Bites for 1d6 + disease.

8. Emu - Pecks for 1d4.  Easy to sever: neck only has 1 HP.

9. Bird of Paradise (the flower) - Can cast cure light wounds at will.

10. Ibis - Peck 1d4.  Save or lose an eye.

11. Gorilla Hand - Attempts to steal your weapon and hit you with it.  Str 16, Dex 12.

12. Rhino - Gores for 1d10 damage.  On a miss, there is a 2-in-6 chance that the rhino horn gets stuck in something, trapping the rhino head there for 1 turn.

13. Elephant - Gores for 1d12.  Never forgets.  (Attacks whoever attacks it first, and never changes targets.)

14. Shark - Bites for 1d8.  If the attack roll is 1-3, it attacks another head instead.  If the other head is a carnivore, the two heads will start fighting, only stopping when one head is bitten off.  (This causes two heads to grow, as normal.)

15. Sloth - Stays asleep until it takes damage, at which point it wakes up and starts biting for 1d4.

16. Viper - Bite 1 damage, save or take 3d6 more over 3 turns.

17. Penguin - Peck 1d4, Every 3 turns, breath a cone of frozen air, 3d6, 20' cone.

18. Zookeeper - Does nothing except scream about emus and madness, begs to be killed, yells at players to bring salt.

19. Cage - On a hit, traps a player inside.  On subsequent turns, beats "head" against ground, dealing 1d6 damage to occupant automatically.  Made of solid metal, but the lock can be picked as normal (usually requires one round to climb on it, and another to pick it, retrys allowed).

20. Dolphin - Doesn't want to fight.  It will just make stupid dolphin noises all fight.  If it is the only head remaining on the body (i.e. it is a dolphydra) it will run away.  It's also tamable, if you have fish.

Barnyard Chimera

HD 7 AC leather Attacks (see below)

Move 15 Int 3 Mor 7

The central cow head gores for 1d8 damage.

The left pig head bites for 1d6.

The right goat head rams for 1d4, but does 3x damage on a charge.

The goose-headed tail spits goose shit (ranged attack).  On a hit, the target is blinded until they spend a turn wiping it away.

When killed, the barnyard chimera splits open and spills out 3d6 featherless, bloody chickens with red eyes and sharp talons.  The chicken have HD 1, AC leather, and claw for 1d4.

It runs on horse legs.  It can speak, but it is only repeating mindless farming phrases.  "How about that weather, huh?"  "Well, let's finish up and then have supper."  "Aw hell, she's coming out breach."

False Hydra

is not a hydra, but is listed on this page for the sake of completeness.

New Class: Really Good Dog

So, here's my dog class.

I'm still thinking about class duets--two players that play closely linked characters.  In this case, a PC and their loyal dog.  It's more one-sided than the Brute/Rider classes I posted earlier, since all of the duet abilities are piled onto the dog.

Here are all of the class abilities.

by Sandara

Really Good Dog

You're a Dog

You can't hold things in your hands. You can't climb ropes or ladders. Your Movement is 15 (Human Movement is 12). Your bite attack counts as either a dagger, sword, or greatsword (your choice, each bite). You do not start with any items. You can follow (most) scents, and recognize scents you've encountered before.  You can understand the words of your fellow PCs and those that your fellow PCs are talking to (via body cues and doggy intuition), but if you are interacting with NPCs alone, you are pretty clueless.  You understand Common, but cannot speak it.  You speak Canine fluently.

You're an amazingly intelligent dog: roll Int normally, but be aware that this is doggy Intelligence, and isn't suitable for all things.  For example, you can spot a trap, count coins, or remember a location you haven't been to in years.  However, you can never solve linguistic puzzles or use tools, because smart dogs aren't smart in that way.

Best Friend

Pick a best friend. You both get +1 Defense and +1 Save when fighting beside each other. This designation is permanent (until story/DM say otherwise).  If your Best Friend dies, you can pick a new one after playing 1 full session as a sad, sad dog.

Best Friends Fight As One!

If you and your Best Friend attack the same enemy simultaneously, and both attacks hit, the enemy takes an additional +1d6 damage.

Best Friends Never Give Up!

If your Best Friend is ever at 0 HP, you can lick their face to restore 1d6+1 HP.  If your Best Friend is ever paralyzed, mind-controlled, raging, or otherwise out of control, you can lick/bite them (whichever is more appropriate) to give them a new save against the effect.  Only works on things that allow saves in the first place.

Wag

When you wag your tail, you cast a version of charm person that only works on children and +Luka Rejec.

Dodge

While unarmored and able to defend yourself, you get a bonus to your AC equal to your level, to a maximum of +6.

Scent the Ineffable

As detect poison, detect evil, detect magic, or detect undead except you cannot decipher magic items and the range is limited to 1', except for detect undead where the range is 30'.

Dog Quest

At a certain point, you will attract the attention of the Dog Barons.  They will give you a quest to prove your doggishness.  Example quests include killing a Cat Prince (rakshasa) who is hiding in town somewhere, digging into a forgotten barrow and returning with the femur from the wight king who was buried there, or rescuing some asshole prince who fell down a well in orcish territory.  (This will probably involve the other PCs chasing after you shouting "Where are you going, boy?  Come back!")

If you refuse or fail this quest, you will be shunned by the Dog Clans of the cities.  If you succeed, you will win allies among the Dog Clans, and can call on their help in the cities.  Examples of help: gossip, relaying messages, safe houses, and in certain circumstances--a whole pack of mangy street dogs who will fight for you.

Growl

An enemy who can hear you must Save vs Fear or be unable to attack or approach you until your next turn. Doesn't work if you are running away, restrained, or non-threatening.  Doesn't work on things with 2 or more HD than you.

Sniff the Air

10 in-game minutes before the DM rolls for wandering monsters, he also rolls for wandering scents.  The DM rolls on the wandering monster table and describes what one of the monsters smells like.  If you've encountered that type of monster before, you can identify it.  (Communicating the information, however, might be tricky.)

Takedown

When you bite an opponent no larger than a human, you can make a trip maneuver for free. 

Talking Dog

Through magic or mutation, you can now talk.

Epic Nose

You can track anything that passed through here in the last 100 years without error, as long as you know what it smells like.

by Ben Wootten

Playing A Really Good Dog in Your Home Game

Honestly, not being able to communicate effectively, use tools, or even climb a fucking ladder are pretty big disadvantages in my book.  So, I recommend basing the Really Good Dog on a fighter, minus any special fightery abilities (like Parry or Cleave).

Then add this stuff.

Level 1 - You're a Dog, Best Friend, Wag, Dodge

Level 2 - Sniff the Air, Best Friends Fight As One!

Level 3 - Scent the Ineffable, Dog Quest

Level 4 -Takedown, Best Friends Never Give Up!

Level 5 - Talking Dog OR Epic Nose

Also, ask your DM if you can roll up a weird dog from Zak's Table of Weird Dogs.

from Dragon Age

Playing a Really Good Dog in Centerra

You're probably a Brynthic Hound, one of the immortal warrior-dogs that get passed down through generations of warrior-families like heirloom swords.

New Classes: Brute Rider and Rideable Brute

This is another brainstorming session.

I'm trying to invent paired classes: two players choose two characters that have highly complimentary abilities.  Or even co-dependent abilities.

from Bioshock

Rideable Brute

Brutish
Even even level, increase the damage you deal with non-magical 2-handed weapons by +1.  Except for magic hammers.  You can still use magic hammers and get the bonus.

Meatbag 
Double your HP.  Double your rate of non-magical healing.  You cannot wear armor.  You get -2 AC.

Cleave??
Whenever you kill something with a blunt weapon, you can make a free attack roll against a target within 30'.  Note that you aren't cutting two people in half with one swing, you're smacking goblins into goblins, or knocking a orc's head across the room like a fanged golfball.  Usable only 1/round.

Mosh
Whenever you shove or trip someone in combat, your Rider (if any) gets a free attack roll against them.

Extra Carrying Capacity
Treat your Strength as 4 points higher when calculating carrying capacity.

Party Crasher
Whenever you initiate combat by breaking down a door and barging into a room, you reduce all damage you take by 3 for one turn, and your Brute Rider can make a free attack.

Dramatic Exit
This is the equivalent of Gandalf and the Balrog falling off the bridge together.  At the end of a charge, you can make an opposed Str check against a target instead of an attack roll.  If you succeed, you grapple the target and charge offstage.  The target dies 90% of the time; the other 10% of the time it returns later on to piss you off.  You remain offstage until your Rider whistles you back (see below).  If you have a rider, they are forced to hop off or suffer the same 90% die chance.  You can only use this ability when there is a place to dramatically charge to, such as a deep pit, a dark and stormy sea, or a green devil face.

by Wildweasel339

Brute Rider

Dramatic Whistle
When you whistle, your a Rideable Brute who is offstage (from using Dramatic Exit) has a 50% chance to return in an equally dramatic fashion (usually busting through the wall).  You can use this whistle once every 10 minutes, but never in the same room twice.  This provokes a random encounter check as usual for noise--but if this whistle results in both the Brute and a random encounter happening, both of those parties bust into the room already mid-combat (and probably with the brute trying to ride the elephant-snake or something).

Knee Chokehold
If you successfully pin a target, you can climb up on their shoulders and wrap your legs around their neck.  In this position, you can instantly choke them unconscious or even kill them.  You can do these things even as a reaction, when it's not your turn, fast enough to interrupt another person's action.  You usually use this ability to coerce unwilling creatures into being your mount.

Motivate the Brute
Whenever you are riding a Rideable Brute and get a critical hit with a weapon, your brute immediately gets an extra attack (but not any movement).

Eject
Instead of rolling to save against an AoE effect, you can instead choose to avoid it all together, by jumping 1d4 * 10' in a random direction.

Fancy Rider 
When you are riding something and wearing a fancy hat, you get an additional +1 to hit and AC (in addition to the +1 to hit and AC you normally get for riding on a tall steed).  Remember that you cannot attack people on the ground with short weapons (like daggers).

Throwable
If your Rideable Brute (or other ogre-sized thing) throws you, you travel up to 50' and take no collision damage if you successfully hit your target, or alternatively, make a Dexterity check.  If you hit a target at the end of this, you can add the Rideable Brute's Str bonus to the damage.  Treat this as a charge (among other things, you deal double damage with a lance).

Magic Drugs
Once per day, you can give some drugs.  Target must be willing, or you must be able to stuff drugs up their nose somehow.  You can use this ability an additional time every odd level (so 2/day at level 3, etc).

List of Magic Drugs

1. Rouse - Wakes a sleeping person and makes them immune to sleep for 24 hours.  They still become exhausted as usual, though.  Dying creatures also stabilize and wake up.

2. Rage - Identical to a barbarians rage.  (You probably have your own ruleset, but I like +2 to hit, +2 to damage, immune to fear and pain, cannot do anything defensive or tactical, and cannot stop raging until all enemies are defeated.)

3. Opiate - Target gets +1d8 temporary HP.  The next day, their maximum HP is decreased by the same amount, to a minimum of 1.

4. Bath Salts - Target becomes immune to emotions.  The first time they take damage while in this state, there is a 1-in-6 chance that they fly into a rage (see above) except that they'll attack a random person in front of them and try to eat their face.  (People riding on their back don't count.)  Regardless, this effect ends after 1d6 minutes.

5. Amphetamines - Target increases their movement by +6 for 10 minutes.  (So a human could run as fast as a horse.)  Afterwards, they get -6 movement for 1 hour.  (So a human's speed would be halved.)

by Casey Parkhurst

Discussion

Well, I like the flavor.

Huge HP, super-shitty AC is fun.  I've played with a similar rule for my homebrew barbarians (I call it loincloth HP) and so far it hasn't pissed me off you.

The Brute's abilities all point to a very specific playstyle: kick down the door, start shoving people, and then tackle people off a cliff.  I worry that it might be too restrictive, but hopefully, the people who play this class desire exactly that type of play.

The Rider's abilities are a little less cohesive.  Carry a spiral lance, shove drugs down the nose of your Brutesteed, and prepare to get thrown now and then.  The Knee Chokehold isn't mechanically very impressive (it's just putting a gun to someone's head and telling them to carry you around and do what you say), but spelling it out like that reinforces the option enough that players might see that as a first resort, which is potentially cool.

The most interesting ability on this page, though, is the Dramatic Whistle / Dramatic Exit pairing.  It sort of plays around with the idea that there is a place called "offstage" (something shared with my doppleganger class).  Yes, gamist.  Yes, storygamey.  But it looks hella fun (Blarguntharg tackled the illithid into the bottomless pit; we're done here but we need to wander around the dungeon looking for him and whistling.) and I don't think it's OP, given how restrictive it is.  (How many mechanics require a bottomless pit to be nearby?)

by Matt Kohr

Using This Stuff In Your Game

Oh, jeez.

Base it on the cleric's numbers, but drop the clericish abilities.  Then they get abilities at these levels:

Rideable Brute
Level 1 - Meatbag, Mosh, Extra Carrying Capacity
Level 2 - Brutish
Level 3 - Party Crasher
Level 4 - Cleave??
Level 5 - Dramatic Exit

Brute Rider
Level 1- Eject, Magic Drugs, Fancy Rider
Level 2 - Motivate the Brute
Level 3 - Knee Chokehold
Level 4 - Throwable
Level 5 - Dramatic Whistle

That arrangement ensures that they both get a cooperative ability every other level.

Flavor

Yes, the classic one is a goblin riding an ogre.  But why not a little girl riding a pygmy dragon?  Or a mosquito man riding his enormous wife?  Or a mutant baby riding a giant mutant baby?  Season to taste.

by Pabelbilly

Player-Player Bonds

So a lot of games establish player bonds during character creation.

"You once fought along side the person to your left."

"You have sworn to protect the person on your right."

Et cetera.  And that's a pretty cool idea.  But. . . it's possible for that sweet backstory to drop into the background.  Players and DMs might easily forget that Alice swore to protect Bob.

Hopefully, if those bonds are represented mechanically, they'll be more in the forefront of everyone's mind.  For example, if two member of your adventuring party are ex-husband and ex-wife, they might share a Vendetta, and be paying very close attention to each other's turns, because the Vendetta ability triggers whenever the other person fumbles.

Player-Player Bonds

1. Battle Brothers/Sisters - Years spent fighting together.
You each get +1 to hit as long as you attack the same target as your battle brother/sister simultaneously.

2. Destined Twins - You share everything.
Your HP is pooled and shared between the two of you.  Any negative physical effect that happens to one of you happens to the other, including death and or maiming.  (e.g. sympathetic limp if the other one loses a leg, nausea if the other one throws up, etc.)  This also works well for conjoined twin characters.

3. Favored Son or Daughter - You adventure alongside your offspring.
Your favored son or daughter must be lower level than you (and therefore, probably created after you).  They must also be the same race and class.  As long as you begin each session asking them "So what have we learned from all this?" they gain XP 10% faster, and whenever you assist them, you can double your bonuses you add to their attempt.

4. Friendship - Merry and Pippin.
You each get +4 to save vs fear when fighting beside each other.

5. Love - Shouldering one another's burdens.
When the object of your love would be hit in combat, you can take the blow instead.  This doubles the damage that the attack does.  Only works if you are adjacent to the target.

6. Master or Mistress - You have a servant or a slave.
Whenever you would take damage that would drop you to 0 HP or less, you can shove your servant in the way instead, as long as they are adjacent to you.  You take no damage, and your servant takes twice as much damage as you would have taken.

7. Multiple Personalities - A person of two minds.
This isn't really a player bond, it's more of a metagame mechanic.  Two players play this character, so if player A isn't there, player B plays that character.  If both players are there, treat the character as if they were 1 level higher.  If there is disagreement of what to do, flip a coin to determine who the dominant soul is.  This dominant soul cannot be challenged for 30 minutes of game time.

8. Protected - People are guarding you with their life.
If you take no damage during an entire gameplay session, everyone gets +10% xp. If you die, everyone gets half xp this session.

9. Rivalry - Striving to outdo one another.
When your rival gets a critical success, you get +4 on your next roll of the same type and crit on a 19-20, as long as it's made quickly.  You don't necessarily want them to fail, you just want to outdo them.

10. Servant or Slave - You have a master or mistress.
If your master spends their entire action giving you a command, you immediately get a free action to carry it out. (Hopefully this leads to lots of "Iago, slay this villanous goblin!"  "Yes, master!  I attack the goblin!") You must succeed on a Charisma check to disobey your master, or lie to them.  (You should also decide if you love your master or hate them.)

11. Sworn to Protect - Bound by honor.
If you are standing adjacent to the person you are sworn to protect, you can take hits for them.  Whenever they would take damage from a melee attack, you can roll an attack roll against the monster who damaged them.  If you succeed, the protected person takes no damage, and you instead take twice as much damage as they would have taken.

12. Vendetta - Filled with schadenfreude.
Whenever the target of your hate critically fumbles a roll, you get a +4 on the first roll you make next turn, and critical on a 19-20.  The other person doesn't have to be a hated enemy.  They could just be a cleric from another religion, or your ex.

How to Implement These?

I don't fuckin know.  Maybe at character creation, players who agree to a bond start with -1000xp for every bond or something.  This doesn't de-level them down to level 0, it just delays how long it takes for them to reach level 2.

These Aren't Balanced!

I know.  This was more of a brainstorming session, actually.

Some Dragons

HD 12 AC plate Attacks 1d8/1d8/2d8
Move 15 Fly 24 Int 12 Mor 9

Terrifying - NPCs must make a morale check when first engaging a dragon.  PCs must make a save vs fear (1d6 rounds) the first time the dragon attacks them, and each time a PC is killed dead.  PCs who have killed a dragon get +4 to save against dragon fear (cumulative per dragon killed, until immune).  They also get to write "DRAGONSLAYER" on their character sheet.

Fire Breath - Usable every 1d4 rounds.  6d6 fire, 60' cone, save for half.  If you have a shield, save to avoid all damage.

Reprisal 2 - Up to twice per round, make a 1d8 melee attack against an opponent after they make an melee attack against you.

Mettle 2 - Twice per day, reroll a failed save.  It cannot use this ability when below half health.  It cannot use this ability against ice effects, or things that target dragons specifically.

I usually run low-level games, so I imagine this dragon being appropriate for a level 3-5 party.

So, I've been thinking about the same things that +Gus L was thinking about when he wrote his post about making big boss beasts more resilient against the usual PC tactic of surrounding them with NPCs and winning simple because they get 12 attacks vs the dragon's 3.

Fear is a good way to keep the mooks off the dragon.  You might bring six mercenaries, but 4 of them lose their nerve as soon as they see how big the damn thing is.

And an AoE attack is also a good cure for the swarm tactics.  True, there are arrows and other ranged attacks, but if the party has enough room to shoot arrows, they're probably outdoors, and if they're outdoors, the dragon can just drop boulders on them, do strafing runs of fire breath, etc.  I'm not too worried about a dragon outdoors.

Reprisal is yet another countermeasure against swarm tactics, and another way to punish people who want to get into melee with a dragon.  That's like a rabbit wanting to get into melee with a wolf.

And lastly, Mettle provides some insulation against save-or-die effects.  There's still a chance you can baleful polymorph the dragon into a snail on the first turn, but it's much smaller.  Allowing certain abilities to pierce Mettle means that prepared parties aren't screwed.  And lastly, the fact that Mettle vanishes once the dragon is below half health, means that players might want to start throwing save-or-die effects once the dragon is bloodied.  If they've gotten the dragon to half health, they've earned it.

The biggest downside to Mettle is that it's largely a gamist mechanic.  Sure, you can pass it off as "legendary willpower" or something, but it's not intuitive.  Honestly, once the party got into combat with the dragon, I'd probably just read them the text from Mettle so they know how it works.

Further re dragons:

Of course, the best counter for player-level plotting is intelligence.

Dragons are smart enough to beat a tactical retreat when they get surrounded.  If they retreat deeper into their lair (flying down the vertical abyss) you can rest assured that the dragon has an excellent ambush spot prepared up ahead.  Perhaps they attack after loosing some rolling boulders.  Or when the party is crossing a narrow span, single-file.

And if a dragon is forced to retreat outside of its lair, that's not a problem either.  They'll ambush the party when they attempt to leave the lair, performing strafing runs as their breath attack refreshes, careful to stay out of arrow range.  Or, they'll block off the dungeon with boulders, and return after hunger and thirst have weakened the party.

Dragons rarely live alone.  They have a mate and some whelps, or they surround themselves with servants: kobolds, goblins, or humans who benefit from the dragon cult.

Centerra only has one race of dragons (no stupid spectrum of rainbow powers) but it does have a lot of unique, singular dragons.  Most dragons out in the wilderness are one-of-a-kind.

Man Dragon

It looks like a human, bent, stretched, and warped by biomancy into a mockery of a dragon, imitating their size and shape.

It does not have Terrify or Fire Breath.

Horrify - Like Terrify, except that previous experience against dragons is no help, and targets that fail their save lose their next turn as they vomit noisily and gain 2 trauma points.

Shockwave Shout - Usable every 1d4 rounds.  60' cone, 3d6 damage and knocks targets back to the range of the cone, where they land prone.  If they collide with a solid object, they take 1d6 damage for every 10' more they would have traveled.  Save negates initial damage, but not the knockback, unless they are holding on to something solid.

Origami Dragon

It does not have Fire Breath.  Instead of bypassing Mettle with ice, it is bypassed with fire.

Origami Breath - Usable every 1d4 rounds.  2d6 slashing, 60' cone, save for half. Covers entire area in caltrops.

Made of Paper - Double damage from slashing or fire, triple damage from piercing.

Pinata Dragon

The Pinata dragon is summoned by ringing the fiesta bell on level 4 of the luchador's dungeon.  The longer it exists, the more treasure you get when it is defeated.  However, the older it is, the more dangerous it is.

Lacks Fire Breath and is not Terrifying.  Is weak to fire, not ice, similar to the origami dragon.

Party Breath - Usable every 1d4 rounds.  Deals 1d6 slashing damage for every 2 HD of the dragon, generates an equal number of gemstones worth 100gp each.

Growth 

• HD = number of rounds it has existed.  Max 12.  On round 12+1d4, the dragon vanishes.
• Damage = d4s for HD 1-3, d6s for HD 4-7, and d8s for HD 8+
• Regenerates 3 HP per turn.
• Takes half damage from non-bludgeoning weapons.  Resists magic 5% per HD.

Sludge Dragon
Lacks Fire Breath.  It cannot fly.

Sticky - Anyone hitting it with a melee weapon must succeed on a Str check or the weapon remains embedded in the dragon.

Sludge Bomb - Usable once every 1d4 rounds.  Bursts like a fireball with a 20' radius, 200' range.  Targets take 3d6 damage and are covered with acidic sludge that deals 1d6 damage and slowing targets (half speed, -2 to hit) until they are washed off with water.  If they are struck a second time, they are immobilized.  A save halves the initial damage and avoids being covered in acidic sludge.

the horror that is the MAN DRAGON

Thungrum (Elephant Ogres)

Illustrated by the excellent +Luka Rejec
What panache!  (Both artist and art.)

HD 6 AC plate Claws 1d12/1d12
Move 18 Int 8 Mor 8

Incredible Leaping Ability - 40' standing horizontal, 20' vertical.

Void Adapted - Can survive happily in a vacuum.  Can hold breath for 2 hours.

Maim - Any slashing attack that does at least 6 points of damage severs a random limb.  If this is an arm, it loses one of its attacks.  If it is a leg, it's speed is cut in half.  This provokes a morale check.  Severed limbs can be re-attached in a single round, but are not regenerated.

Wants to kill people, organize items, and wear hats.

Fights by intelligently but extremely aggressively, tearing off arms, breaking jaws in half with both hands.

They look like blue-skinned ogres with deformed, vaguely-elephantine heads.  They behave as beasts, except that they wear clothing.  They are fond of wide-brimmed hats and long cloaks.  They are vegetarians.

They live in caves, thickets, and abandoned places.  They do not use weapons.  They do not speak or respond to speech.  They ignore animals, but kill every sentient creature they come across, and bury them in straight lines after stripping them all all equipment and clothing.

Each thungrum keeps an inventoried hoard of stolen items, always immaculately organized.  Items are sorted by size, color, and purpose.  They are deaf, but have a keen sense of smell.  They have good eyesight, but do not close their red-rimmed eyes until they are dead.

Ogres know and fear them.

The Madness of the Thungrum (roll when first encountered) [d10]
1. Elaborate pantomime of surprise before attacking.
2. Will keep its distance, throwing pebbles.  It will attack one round later.
3. Will charge through the party before returning 2 rounds later to attack.
4. Appears in front of the party to stare at them.  Prepares an action to leap at and attack the first person to do anything at all.
5. Attempts to join the party, usually walking at the end of the column.  Attacks as as soon as it is noticed.
6. Surprise attack!  Sudden, horrible death.
7. Party is unnoticed.  Thungrum is staring at the sun.
8. Party is unnoticed.  Thungrum is lying on the bottom of a stream, breathing through its long nose.
9. Party is unnoticed.  Thungrum is in its lair, noisily arranging its collection.
10. Party is unnoticed.  Thungrum is burying people it has killed, kissing each one.

Hoard of the Thungrum (roll 1d6 twice, then 1d20 twice)
1. 2d6 pairs of shoes, each worth 5gp.
2. 1d6 chests of silverware, each worth 20gp
3. 1d20 fancy hats, each worth 10gp.
4. 1d6 suits of medium armor, each one different and worth 50gp.
5. 1d6 barrels of trade goods.  Beer, silk, or spices.  Each worth 50gp.
6. 1d100 copper coins, 1d100 silver coins, and 1d100 gold coins.
7. Suit of ceremonial platemail with a rooster theme.
8. An entire wagon, entirely dismantled and sorted by size.
9. 1d1000 golden coins arranged by condition.
10. A spellbook with 1d4+1 spells, each page unbound and framed.
11. 2d6 books, arranged by color.
12. A full set of furniture (bed, table, sink, bath tub) adorns the cave.
13. 2d6 half-feral cats.
14. 2d6 weapons, arranged by color.  5-in-6 one is masterwork, 1-in-6 it is magic instead.
15. 2d6 paintings.  (Note to self: write a painting generator.)
16. 2d6 women's dresses, arranged by length.
17. In dozens of alcoves, the sorted pieces of a dozen clocks.
18. 3d6 differently colored liquids, each in a vial.  1 is poison, 1d6 are potions.
19. laser pistol (3d6 damage, 1d6 charges left)
20. 2d6 cloaks, 1-in-6 that one of them is a Cloak of the Thungur (huge leaps, but you are unable to do any action except attack something directly or remove the cloak)

DM Secret: Thungrum are ogroids engineered for space combat.  When they arrive on Centerra (by one method or another) the nitrogen-rich atmosphere drives them insane.  Somewhere in the back of each Thungrum's brain, there is an intelligent, noble warrior struggling to communicate.

The Bestiary

I've only included the monsters that are interesting and/or non-trivial.  Some of them are inside PDFs, so you'll have to go through the PDFs to find them.

Aside from that, this is a complete index of all the monsters I've ever posted.  It's from all 3 of my settings (Centerra, Eldritch Americana, and Synthexia).  Mostly Centerra, though.  Nearly all of them have stats, but not all.

I'll update this list as I add more beasties.
