Actions

Multiattack The Lonely makes one harpoon arm attack and uses Sorrowful Embrace.

Harpoon Arm 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. The Lonely has two harpoon arms and can grapple up to two creatures at once.

Sorrowful Embrace Each creature grappled by the Lonely must make a DC 15 Wisdom saving throw. A creature takes 18 (4d8) psychic damage on a failed save, or half as much damage on a successful one. In either case, the Lonely pulls each creature grappled by it up to 30 feet straight toward it.
