Acid blast is a monster spell that appears in EvilHack and Hack'EM, and functions similarly to the spell of acid blast.


Acid blast can be used by any monster that can cast mage spells and is at least level 15. When cast, the caster will target a monster that they can see (or the square where they believe that monster to be) with a 3x3 explosion of acid centered on that square; if successful, the explosion can corrode unprotected armor and wielded weapons in the open inventory of any monsters caught within. The spell can miss the monster and blast the floor or ceiling harmlessly, and will have no effect if the target has complete acid resistance.

Monsters will not use this spell against a monster that is peaceful and not subject to a grudge, or else one they know to have acid resistance. Monsters will also avoid using the spell if they are not aware of an appropriate target, would be caught in their own blast, or else they would target you while you have invulnerability, e.g. from a successful prayer.


The acid blast spell makes acid resistance a necessity in the late game, as a successful hit can burn through a chunk of a character's HP: acid resistance can only be obtained extrinsically, making it important to have room in a character build for the property when planning to face specific monsters such as Kathryn the Ice Queen, even on a temporary basis.
