Mated pairs work together to bring down large game, while lone worgs usually chase down creatures smaller than themselves. Both often use hit-and-run tactics to exhaust their quarry. A pack usually circles a larger opponent: Each wolf attacks in turn, biting and retreating, until the creature is exhausted, at which point the pack moves in for the kill. If they get impatient or heavily out-number the opponent, worgs attempt to pin it.
Trip (Ex): A worg that hits with a bite attack can attempt to trip the opponent as a free action (see page 139 in the Player's Handbook) without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the worg.
Skills: A worg receives a +1 racial bonus to Listen, Move Silently, and Spot checks, and a +2 racial bonus to Hide checks. A worg has a +4 racial bonus to Survival checks when tracking by scent.
