Drown

You fill the lungs of one creature that you can see within range with sea water, forcing it to attempt a Constitution saving throw. On a failure, the target immediately begins suffocation (see Player's Handbook p. 183). Coughing and other attempts by the target to physically expel the water from its lungs are utterly useless and it cannot speak while drowning.

A dispel magic, remove curse, or similar spell can end this effect. Creatures that do not need air to breathe are immune to this spell.
