Crumble

The crumble spell instantly reduces an inanimate objects water content to zero. Up to one cubic foot of clay, rock, soil, or other solid per level of the caster can be desiccated to the point that it loses cohesion, cracks, and crumbles. A 7th level priest could affect 7 axes, or a stone of 7 cubic feet or less.

Nonliving organic materials such as hide, leather, bone, and wood split and crumble into dust when affected by this spell. Liquids disappear instantly and fruit-potions turn to withered husks. Permanent magical items receive a saving throw vs. spell equal to that of the original creator (assume 12th level if this is unknown).

Metals, living organic material, and silicates such as glass are entirely unaffected. Mindless corporeal undead like zombies and skeletons take 1d6 points of damage for every 3 levels of the caster.
