Gnaw (Rank 4) Edit
The werewolf's jaws strengthen to the point that she can chew through just about anything, given enough time. In addition, her jaws do more damage in combat, and only death will break her grip if she clamps her teeth into an opponent. Wolf-spirits teach this Gift.
The player spends one Willpower point and rolls Stamina + 4 against a variable difficulty (3 for wood, 6 for steel handcuffs, 9 for a train car coupling). The length of time it takes to gnaw through something depends on the number of successes. In addition, this Gift gives a character's bite two extra dice of damage for the duration of the scene.
