Gift of the Porcupine (Rank 4) Edit
When using this Gift, the werewolf undergoes a startling transformation. Her fur becomes elongated, bristly and sharp like the quills of a porcupine. This change makes her an even more fearsome killing machine. A werewolf must be in Crinos, Hispo or Lupus form to use this Gift. Porcupine teaches this Gift, and he has a great fondness for metis. The Gift may be used in any form except Homid or Glabro.
The character spends a Gnosis point to sharpen his fur. Anyone whom the metis tackles, grapples or immobilizes takes aggravated damage from his newfound quills (Strength +1). Furthermore, anyone who strikes him with bare flesh (and scores fewer than five successes on the attack roll) takes damage based on the attacker's own Strength, although the metis still takes normal damage. This Gift lasts for one scene or until the werewolf wills his fur to return to normal.
Other terms for this gift are: Teeth of the Skin
