Pack Tactics. The bone drake has advantage on an attack roll against a creature if at least one of the drake’s allies is within 5 feet of the creature and the ally isn’t incapacitated.
Actions
Multiattack. The bone drake makes two attacks: one with its bite and one with its tail.
Bite. Melee weapon attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8+3) piercing damage.
Tail. Melee weapon attack: +5 to hit, reach 10 ft., one target. Hit: 6 (1d6+3) bludgeoning damage, and the target must succeed on a DC 12 Constitution saving throw or become poisoned 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. A creature poisoned in this way has their speed halved and cannot take reactions.
