You fill up the victim’s lungs with a mass of insects, which come streaming out of its mouth and nose the moment the spell is finished.

The subject suffers symptoms similar to drowning unless it succeeds on a fortitude save. On a failed save, the subject’s hit points immediately fall to 0, and it is disabled. Unless it receives magical healing or first aid (see the Heal skill description. You cannot perform first aid on yourself in this case), it loses another hit point at the start of your next turn, and falls unconscious. If it still has not received magical healing or first aid before the start of your turn thereafter, it dies.

Creatures that do not need to breathe or otherwise don’t have lungs are immune to this spell.
