It's a spell from Dungeons and Dragons.

The spell describtion goes: "This spell evaporates moisture from the body of each subject living creature, dealing 1d6 points of damage per caster level (maximum 20d6). This spell is especially devastating to water elementals and plant creatures, which instead take 1d8 points of damage per caster level (maximum 20d8)."

Some of the manuals go on to elaborate that beings killed with this end up looking like mumies.

Sound familiar? :P
