Actions

Multiattack. The Skin Stealer makes two attacks: one with its claw and one with its bite.   Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.   Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage. If the target is a creature, it must succeed on a DC 12 Constitution saving throw or be infected with a potent poison. While poisoned in this way, the target can't regain hit points and takes 5 (1d10) poison damage at the start of each of its turns. The poison lasts until the creature receives a lesser restoration spell or other magic that cures diseases.
