Monster use	Will not be used by monsters.

A potion of acid may not be diluted to water. However, a potion of acid can be cancelled to turn it into a potion of water.

If #dipped in water, acid will boil and cause you 1-10 points of damage (except in containers). Walking into water with potions of acid in your inventory can make them explode, even inside a sack or bag of holding, but they will never dilute or deal damage. The only ways to obtain diluted acid presumably are wishing, or random alchemy results.

If you quaff a potion of acid when you are turning to stone, you will be cured of your stoning. You will abuse your constitution and take 1-4 points of damage if blessed, 1-8 points of damage if uncursed, and 2-16 points of damage if cursed.

Acid is best used either as a thrown weapon or as an emergency stoning cure (primary one for vegans and vegetarians)

If a monster throws a potion and hits another monster with it, or you throw an unidentified potion at a monster, and the monster "shrieks in pain" or "writhes in pain", the potion is a potion of acid. Holy water can give the same message, but monsters do not use it. You will be prompted to type-name the potion unless it already was named.

Bugs

Unpatched vanilla NetHack will semi-reliably crash if you trigger the following bugs. They are fixed on Nethack.alt.org and in most variants.

• C343-179: If a monster carrying acid is crushed with a drawbridge, the game may panic. Same result if you or another monsters blows up the drawbridge underneath it.
• C343-394: Throwing a potion of acid into water (pools, moat, swamp) or at iron bars will reliably crash the game.
