Pack attack. Wolves work together well. Any wolves adjacent to the victim count as flanking, gaining the +1d6 bonus to attack. When 3 or more wolves are adjacent to the victim, the victim becomes overwhelmed, and is rendered Fatigued at the start of its turn.
Pounce. The wolf can jump its horizontal jump distance (8') from a standing start when making a bite attack. This counts as a charge (+1d6 damage), and also knocks the victim prone on a successful attack.
