Traits

Rejuvenation. While its master lives, a destroyed boneclaw gains a new body in 1d10 hours, with all its hit points. The new body appears within 1 mile (1.3 km) of the boneclaw's master.   Unusual Nature. The boneclaw doesn't require air, food, drink, or sleep.

Actions

Multiattack. The boneclaw makes two Piercing Claw attacks.   Piercing Claw. Melee Weapon Attack: +6 to hit, reach 15 ft. (3 sq.), one target. Hit: 8 ( 1d10+3 ) piercing damage plus 5 ( 1d10 ) necrotic damage. If the target is a creature, the boneclaw can pull the target up to 10 feet (2 sq.) toward itself, and the target is grappled (escape DC 12). The boneclaw has two claws. While a claw grapples a target, the claw can attack only that target.   Shadow Jump (Recharge 1d6>=5 ). Constitution Saving Throw: DC 12, any target of the boneclaw's choice within 15 feet (3 sq.) if the boneclaw is in dim light or darkness. Failure: 14 ( 2d12+1 ) Necrotic damage.   The boneclaw then teleports up to 60 feet (12 squares) to an unoccupied space it can see. It can bring one creature it's grappling, teleporting that creature to an unoccupied space it can see within 5 feet (1 square) of its destination. The destination spaces of this teleportation must be in dim light or darkness.

Bonus Actions

Shadow Stealth. While in dim light or darkness, the boneclaw takes the Hide action.
