Multiattack. Bonecracker uses Mesmerizing Chir (if available) and then makes two melee attacks.
Bite. Melee Weapon Attack: +3 to hit ( 1d20+3 ), reach 5 ft., one creature. Hit: 12 2d8+3 piercing damage. If the target is a creature other than an undead, it must succeed on a DC 10 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Claws. Melee Weapon Attack: +5 to hit ( 1d20+5 ), reach 5 ft., one target. Hit: 10 2d6+3 slashing damage. If the target is a creature other than an undead, it must succeed on a DC 10 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Warped Falchion. Melee Weapon Attack: +6 to hit ( 1d20+5 ), reach 5 ft., one target. Hit: 10 2d6+3 necrotic damage. This is a magical attack.
Mesmerizing Chirr (Recharge 6). Bonecracker makes a chirring noise to which frogloks, grungs and undead are immune. Each humanoid or beast that is within 15 feet of the him and able to hear it must succeed on a DC 12 Wisdom saving throw or be stunned until the end of the Bonecracker’s next turn.
Trill of Death. When reduced to half his starting hit points, Bonecracker's Mesmerizing Chirr recharges and he may immediately use it as a reaction.
