Drown

You create water in the lungs of the subject, which begins to drown.

The subject can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round). At the start of its next turn, it drops to 0 Hit Points and is dying, and it can’t regain Hit Points or be stabilized until it can breathe again.

Coughing and other attempts by the victim to physically expel the water are useless.

Undead, constructs, creatures who do not need to breathe, and creatures who can breathe water are unaffected by this spell.
