Regeneration. Vodra regains 3 hit points at the start of its turn if it has at least 1 hit point.

Multiattack. Vodra makes three attacks: one with its song and two with its claws.

The Song. Ranged Attack; DC 13 Constitution saving throw, reach 20 ft., one target. Hit: 3 (1d6) piercing damage.

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 2 (1d4) slashing damage. If the target is a humanoid, it must succeed on a DC 13 Constitution saving throw or be infected with eternal drowning. While infected, the target cannot breathe as water is magically filling up their lungs. They must make a DC 13 Constitution saving throw at the end of every turn or gain a level of Exhaustion and take 1d4 damage. If a humanoid dies during this effect they rise as a Drowned One.
