Publication:Renegade Cleric's Tome/Absorption

You cause any liquid carried by a creature to dry up. The spell affects potable waters as well as potions, although magical potions get a saving throw to resist the effect. Potions carried by a creature can use that creature’s Fortitude saving throw bonus or their own, whichever is better.

While the spell instantly dries up water carried by a character, it can only destroy a limited number of magic potions. Potions destroyed are limited to those whose total spell levels are less than half the level of the spell’s caster. For example, a 7th level caster can destroy a potion of mage armor (1st level), and a potion of barkskin (2nd level) but is unable to destroy any more potions.

Which potion is affected first should be determined randomly. The target of the spell knows that something has happened to the liquids in their possession but does not know which potions, if any, might be ruined until they take the time to examine all of their vials. The spell cannot be used against a living creature or plant to dry up its blood or liquid.
