Corrupted Potions

Another bit of rumination on Potions and their sensitivity to the environment around them, in contribution to Of Dice and Dragons' October RPG Blog Carnival topic.

Part 1 here.


While there are a number of spell failure tables and mechanics are available, I don't know if there are any for potions (or I'm just lazy and never looked).

I would theorize that, although potions are typically treated as infallible 'magic bullet' items in game-playing, that in 'reality' they may be more unreliable - concoctions brewed by sketchy alchemists, or enchanted by second-rate mage's assistants...

Additionally, if the potion is considered a distillation enchanted with a spell effect, would the fluid be susceptible to magical influences?

So... A consideration of a few things, in no particular order, that may have an effect on a lowly potion, minding its own business in its flask or vial....



  • Sharp knocks or shaking
  • Exposure to magical attacks on bearer
  • Exposure to magic use by bearer
  • Chaos forces
  • Dragon fire
  • Proximity of magical critters or constructs
  • Environmental contamination or corruption
  • Fungi
  • Poor seal on container leaking fluid or magical essence
  • Exposure to light
  • Improper preparation
  • Extreme temperatures
  • Chemical/alchemical interaction with improper container
  • Cross-contamination with other potions or liquids
  • Fermentation
  • Exposure to the aether during planar travel
  • Exposure to abyssal creatures/beings
  • Divine intervention 
  • Elapsed time since the potion was created
After all, the world is a big, scary place...

I'm not going to formally estimate what proportion of portions may be corrupted by one variable or another.  Perhaps the potion fails a save vs the hazard.

It just depends on how scary and random magic is in the particular game-world of the players.  Something to add a bit more uncertainty before quaffing that potion of cure light wounds, or fly....

Potion corruption effects (d100):

1-2: Poison (save vs death or damage, dependent on 'level' of potion magic)
3-6: Coma (1d8 days)
7-9: Paralysis (limb 80%, full 20%, save vs permanent)
10-15: Potion effect reversed (if applicable)
16-19: Light sensitivity (-1 to actions in full light, similar to goblins)
20-23: Anaphylactic shock
24-26: Blinded (save vs permanent)
27-29: Mute (save vs permanent)
30-34: Drowsy to asleep (1d8 hours)
35-39: Sleepless, hyperactivity (1d3 days)
40-45: Hallucinations (1d6 hours)
46-49: Numbness of limb, face, lips (1d8 hours)
50-53: Sense of taste, loss or hypersensitivity (1d4 days)
54-58: Ringing ears (1d8 hours)
59-61: Hair falls out
62-64: Hair grows everywhere
65-70: Delayed effect (1d4 hours)
71-74: Skin becomes scaly, hardened (Improve natural AC 60%, decrease Dex 1pt 40%)
75-81: Potion ineffective/inert
82-85:Potion effect halved
86-89: Potion transmuted into another potion entirely
90-94: Potion has secondary potion effect (random)
94-98: Potion effect doubled
99-00: Permanent effect, usable once per day

(Feel free to add to or mod up the table, or simply use it as a starting point or shopping list for potion randomness...)
