Drown (3.5e Spell)

You create water in the lungs of the subject, causing it to begin drowning as if it had failed to continue holding its breath. The subject's hit points immediately drop to 0, and it falls unconscious. In the next round, it loses another hit point (bringing its hit points to -1) and is dying. In the following round, it dies. If the creature already has zero or fewer hit points before suffering either of these effects, it falls unconscious normally but its hit points do not change as a result of the spell.

A successful Heal check with a DC equal to 10 plus your caster level, heal, limited wish, wish, or miracle spell in the intervening period saves the victim and removes all negative effects of this spell.
