A nereid can flood the lungs of one target within 5 feet that is willing, incapacitated, or affected by her Beguile. She touches the target, traditionally by kissing the creature on the lips. The target must make a DC 15 Constititution saving throw or immediately begin drowning. Drowning creatures begin choking. At the end of each of its turns, the target can make another Constitution saving throw. On a success, the target is no longer drowning.
