Kevetta Dolindar

At the start of each of Kevetta's turns, each creature within 5 feet of it must succeed on a DC 15 Wisdom saving throw or take 10 (3d6) psychic damage.

Kevetta has advantage on attack rolls while it is within 30 feet of at least two other creatures. It otherwise has disadvantage on attack rolls.

Kevetta makes one Harpoon Arm attack, and it uses Sorrowful Embrace.

Melee Weapon Attack: +7 to hit, reach 60 ft., one target. Hit: 21 (4d8 + 3) piercing damage, and the target is grappled (escape DC 15) if it is a Large or smaller creature. Kevetta has two harpoon arms and can grapple up to two creatures at once.

Each creature grappled by Kevetta must make a DC 15 Wisdom saving throw, taking 18 (4d8) psychic damage on a failed save, or half as much damage on a successful one. In either case, the sorrowsworn pulls each of those creatures up to 30 feet straight toward it.
