The Perfect Potion List

I did something a little different today.  I tried to write out the potion tables for my fantasy heartbreaker, the GLOG.

Usually I just try to pump out as much fresh brain juice as possible, which is fun because I just write about whatever is interesting.  But today I was trying to answer the question of "what is the best possible potion list to have in a game"?  Which is a surprisingly different process.

I wrote a list of potions, nearly 200.  A lot of them were crappy and I deleted them, but it was clear that the best potion list is not the longest potion list.  You want to distill the good stuff down and discard the chaff.

Sure, a bloated potion list is good for DMs to steal ideas for their own adaptations.  But a system's core potion list should be as high quality as possible.  It also needs to be large enough to feel like there's a good variety there.

Anyway, most games have potion lists with about 20 entries, which seems thin to me.

Or they'll have potion lists that are just adapted straight from the spell list.  Which is fine, but it makes it seem that potions are just liquid spells, and I want them to be more than that.  I want potions to have their own feeling and their own lore.

Besides, spells have to be (sort of) balanced.  Potions are things that you find randomly or at the DM's discretion--there's no need to make them psuedo-equivalent in power level.  You can go pig wild when writing them.

I had a few goals when I wrote up my potion list:

• Make a list of 20 old-school potions for people who want a more retro potion list, and who want to avoid the weird stuff.
• Make more potions that were useful for exploration, not just combat.  (Spells are prepared with an expectation in mind.  Potions are just found.  Therefore potions can afford to be more situational than spells.)
• Make potions that are good for solving (and creating) OSR-style challenges (especially of the dungeoncrawling variety).
• Make potions that had multiple (but intuitive) uses.  Unlike spells, potions are a known substance (liquid) with known properties (liquidity).  It has a context and a known behavior (we already know what we can do with 1oz of liquid).  Potions should have uses other than just drinking.  For example, if a potion of invisibility is poured out on the floor, it should make a small section of the floor invisible, creating a window.
• Make a list of 100 potions.

I failed miserably at the last bullet-point.  That's where you come in.

I wrote too many potions.  Please comment on which potions you think are crappiest.  Either because they're boring, or you've seen them too many times, or because they wouldn't lead to good gameplay.

This also works on very large silver objects, with potentially disastrous results.

Mapping

If you believe something is true, it is true for you. This allows you to walk across a chasm by imagining a bridge, or open a locked door by imagining that it is unlocked. This only works if you fail an Int check, and only works on environments and local objects. Lasts 30 minutes, or until you use it once.

Sound Bubble

Creates an invisible, intangible bubble around you with a 10' diameter. Sound cannot pass through this bubble..

Sovereign Acid

Elemental acid. Will melt through anything except glass and adamantine, and will eventually melt a hole all the way down to Hell. If poured on a stone floor, hole is 1' wide and narrows as it goes down. Lethal (and messily so) if drank.

Sovereign Grease

Elemental Slipperiness. Surfaces coated with this become perfectly frictionless. Coats an area about 5' in diameter. Nearly invisible when spread thin. If drank, negates the effects of anything you ingest for the rest of the day; food, edible poisons, and potions will have no effect—they just pass right through you.

Spell Ward

The next spell that targets you fails. Lasts until you go to sleep.

Speak With Beasts

You can speak with all non-swimming, non-flying, non-crawling, animals for 3 minutes (use a timer). Smaller animals tend to be smarter. Carnivores tend to be demanding.

Speak With Birds

You can speak with all flying animals for 3 minutes (use a timer). Birds are usually very smart, very stupid, or very smart and pretending to be stupid. Migrating birds are the primary source of gossip in the world, especially modern gossip.

Speak With Crawling Things

You can speak with all crawling things (such as lizards and slugs) for 3 minutes (use a timer). Reptiles tend to be careful, pragmatic, and stubborn. They usually know the deep history of a place. Insects know many useful things, but they struggle with human concepts of time and identity.

Speak With Dead

You can speak with a corpse as long as it has an intact mouth (or if you reattach the jawbone) for 3 minutes (use a timer). They tend to be incoherent, obtuse, and prone to reminiscing.

Speak With Fish

You can speak with swimming things for 3 minutes (use a timer). Cetaceans want to know all about you so they can fit you into their theories and stories. Fish tend to be amazed by everything, forgetful, and a little awkward. Sharks talk of nothing else except eating things, often times you.

Speak With God

You can speak with a god of your choice, who will answer one question, and optionally a follow-up question. But gods also ask questions of the querent (mostly pertaining to morality or their domains) and will not help you if they don't like your answer. Greater gods tend to be more accurate, but are also more likely to convert you to their religion.

If a god converts you to its religion, you must change one of your Convictions to reflect this. If you would be converted but already worship that god, you are instead compelled to donate to their cult or perform a small quest at that god's behalf at the earliest opportunity. Gods don't speak with words, just crystal-clear impressions, like ideas that someone else plants in your mind.

• Dead gods that dwell in the ashes of the earth are accurate 50% of the time. They are beyond caring about your moralities. You must be underground to speak with them.
• Lesser Slave-gods (such as Briga, the goddess of shoes) and great souls (popular heroes from folklore) are accurate 70% of the time, and have a 10% chance of converting you.
• Greater Slave-gods (such as Brigadoon, the most powerful of the many competing harvest gods), saints, and dead popes are accurate 85% of the time, and have a 30% chance of converting you.
• Zulin, Prince of the Upper Air, is accurate 100% of the time and has a 50% chance of converting you. However, he only speaks to royalty, since he is royalty himself (king of the gods).

Speak With Metal

You can speak with metal for 3 minutes (use a timer). Metal tends to have a pretty good knowledge of everything that has directly happened to it since it was forged, but not things that happened to it. Weapons speak of their kills; locks speak of what they guard. Cursed and trapped metal objects tend to be liars.

Speak With Plants

You can speak with plants for 3 minutes (use a timer). Plants often have either a deep-seated hatred towards things that eat them and cut them down, or resignation. Trees tend towards the hateful side of things, and sigh a lot. Flowers tend to be optimistic idiots and/or sexually graphic. Grasses are nearly impossible to talk to because they all shout at once.

Suggestion

The next thing you say is a suggestion, as the spell of the same name.

The Hero

You are possessed by the spirit of Braddon the Breaker, a legendary hero who was eventually devoured by an alchemical ooze. He is honorable, cheerful, and boastful.

Time Skip

You leap exactly 24 hours forward in time, reappearing in the exact same place.

Tongues

Closing Thoughts

Use more potions.

They're situational tools with lots of different applications.  Lots of them encourage lateral thinking.  They're (a) usable by anyone, and (b) all single-use.

(These are basically the features that define Monte Cook's cyphers in Numenera, and everyone loves those.  With good reason.)

They fact that anyone can use them leads to more tactical thinking.  If you find a scroll you give it to the wizard.  If you find a potion, you need to think about who gets it.

And because they're single use, you don't need to worry about balancing them so much.  A potion is never going to break your game.  Who cares if they use a potion to finish your boss battle in a single round?  It probably took some clever thinking, and there will be more boss battles when they don't have the perfect potion at the perfect time.

Let me know which potions you think are the weakest links.  I appreciate it.
