Traits

• 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.

Actions

• Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 4) piercing damage plus 7 (2d6) cold damage.
• Cold Breath (Recharge 5-6). The wolf exhales a blast of freezing wind in a 15-foot cone. Each creature in that area must make a DC 13 Constitution saving throw, taking 18 (4d8) cold damage on a failed save, or half as much damage on a successful one.
• Trip. If the wolf hits with its bite attack, the target must succeed on a DC 14 Strength saving throw or be knocked prone.
