Trip (Ex): A legendary wolf that hits with a bite attack can attempt to trip the opponent as a free action (see Trip in Chapter 8 of 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 legendary wolf.

Scent (Ex): A legendary wolf can detect approaching enemies, sniff our hidden foes, and track by sense of smell.

Skills: A legendary wolf receives a +2 racial bonus on Listen, Move Silently, and Spot checks, and a +4 racial bonus on Hide checks. It also receives a +8 racial bonus on Survival checks when tracking by scent.

Saving Throws: A legendary animal has all good saves.

Legendary animals are no larger than normal animals of the same kind, but they are considerably more dangerous in combat.

A legendary wolf encountered singly may fight, or may retreat to assemble the pack. Whenever possible, legendary wolves live, move, and hunt in packs.
