Black Wolf - Biscuit 4.0

Keen Hearing and Smell. The wolf has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. The wolf has advantage on an attack roll against a creature if at least one of the wolf's allies is within 5 feet of the creature and the ally isn't incapacitated.

Relentless (Recharges after a Short or Long Rest). If the wolf takes 40 damage or less that would reduce it to 0 hit points, it is reduced to 1 hit point instead.

Multiattack. The wolf makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: (2d8 + 4) piercing damage. If the target is a creature, it must succeed on a DC 17 Strength saving throw or be knocked prone.

Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit:  (3d6 + 4) piercing damage.

Cold Breath (Recharge 5–6). Biscuit exhales an icy blast of hail in a 15-foot cone. Each creature in that area must make a DC 17 Constitution saving throw, taking 36 (8d8) cold damage on a failed save, or half as much damage on a successful one.
