This curse magically creates water inside a subject's lungs, drowning the creature in a few rounds. Nonbreathing creatures and undead are not affected by this spell. Any other creature that fails a saving throw vs. spell immediately begins to drown. See the rules for drowning in Chapter 14 of the Player's Handbook. Once the spell begins affecting a creature, leaving the initial casting range provides no remedy.
The spell can be stopped with remove curse or by disrupting the caster. A dehydrate spell will also cancel lungs of water, and the subject suffers no other ill effects.
The material component is the caster's saliva, spat at the intended subject.
Notes: Uncommon for priests from the Dark Sun setting.
