Gaunt One

Keen Hearing. The gaunt one has advantage on Wisdom (Perception) checks that rely on hearing.

Multiattack. The gaunt one makes two claw attacks. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 14).

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 11 (2d6 + 4) slashing damage.

Extract Heart. Melee Weapon Attack: +6 to hit, reach 5 ft., one humanoid grappled by the gaunt one. Hit: The target must make a DC 13 Constitution saving throw, taking 22 (5d8) piercing damage on a failed save, or half as much damage on a successful one. If this damage reduces the target to 0 hp, the gaunt one kills the target by extracting and devouring its heart.
