Slippery. The rusalka has advantage on ability checks and saving throws made to escape a grapple.

Universal Beauty. The rusalka appears different and uniquely beautiful to match the tastes of each humanoid that perceives it. Truesight reveals the rusalka's true undead form.

Water Bound. The rusalka cannot willingly leave the body of water to which it is bound. If forcibly removed, the rusalka takes 11 (2d10) necrotic damage every minute until it returns.

Charm. One humanoid the rusalka can see within 100 feet of it must succeed on a DC 15 Wisdom saving throw or be magically charmed for 1 hour. The charmed target must spend its turns trying to move as close to the rusalka as it can. The target can't take reactions, and for its action, it can use only the Dash action. If the target suffers any harm, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect ends, the target is immune to the rusalka's Charm for the next 24 hours.

Tresses. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit 14 (3d6 + 4) bludgeoning damage and the target is grappled (escape DC 16) and pulled 5 feet toward the rusalka. Until this grapple ends, the target is restrained, the rusalka tries to drown it, and the rusalka can't use its tresses on another target.

Tickle. One creature grappled by the rusalka must succeed on a DC 14 Constitution saving throw or be incapacitated with laughter for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. R RUSALKA 64
