The Plane of Acid is not uninhabited. The skilled mage can bring forth one of the denizens of this plane. The semi-living blob of acid will instantly consume any items it touches. However, it doesn't last long - within moments it destabilizes and explodes. The strength and size of the explosion depends on the number of items it fed on, so this spell is best cast on a stack of unwanted equipment. And best cast if you already have acid resistance.
Description
Can be cast on any visible square. Consumes all of the items at the target location. Items in a stack are counted as individual items rather than as a single stack. The radius of the explosion is equal to either the number of consumed items, or 10 tiles - whichever is less. It will explode multiple times, equal to (numitems/4)+1. Each explosion of the acid blob deals 6d6 acid damage to those in the splash radius.
This is considered to be one of the most powerful spells in the game. A large stack of items can render a massive explosion. For instance, arrows make excellent fuel for this spell. A stack of 99 arrows will create an acid explosion 10 tiles wide, dealing 6d6 acid damage in a series of 25 explosions, totaling 150-900 acid damage.
