Berserker's Song

The Get can sing himself into a controlled frenzy. He can ignore wounds, shift to Crinos immediately, and he is immune to many mental Gifts or Charms. In this state, unlike a normal frenzy, the Get can pull out of the frenzy at any time. An angry wolverine-spirit or bear-spirit teaches this Gift to the Get.

System: The Garou spends two Rage points and begins singing his particular song of Rage (many young Get prefer "death metal"). The number of successes on a Stamina + Expression (or Performance) roll (difficulty 6) equals the number of rounds the frenzy lasts. She can drop the frenzy earlier by spending a Willpower point.
