Rank 4 Ahroun Gift / Rank 4 Get of Fenris Gift (Camp: Mjolnir’s Thunder) / Rank 4 Red Talon (Kucha Ekundu) Gift
The werewolf with this Gift can bite down with such power that her grip won’t loosen until she chooses to do so; even in death, her jaws bite down. A wolf- or hyena-spirit teaches this Gift.
System: After making a successful bite attack, the player may invoke this Gift by spending a Rage point. For each successive turn she opts to maintain her grip, she makes a bite attack roll (difficulty 3). While foes can make a resisted Strength roll to break the grip (suffering an additional health level of damage in the process of tearing free), the Garou may add half her Willpower to her dice pool.
