Acid is a corrosive threat to you, your pet, your metal weapons and armor and your enemies. It can come from monsters, comestibles, potions of acid ("This burns!"), and perhaps other sources.
The following monsters are acidic:
Acidic monsters (including yourself, if polymorphed into one) dissolve webs instead of getting caught in them.
All acidic monsters, with the exception of Juiblex, leave corpses that are acidic. Eating an acidic corpse does 1d15 damage unless you are acid resistant.
Drinking a potion of acid does 1-16 points of damage and abuses constitution if not acid resistant.
Acid resistance is granted by being polymorphed into an acidic monster or by wearing an alchemy smock, yellow dragon scale mail, or yellow dragon scales. It cannot be obtained as an intrinsic.
