No matter how strong you are, you can't be everywhere. Sooner or later, if you live long enough, every Ahroun will experience the heartbreak of seeing a packmate die in combat, and knowing that they simply couldn't be there to help. Elders have seen this more than any, so it is not unusual that they would learn a Gift like this. This Gift allows an Ahroun to donate his capacities to one of his packmates for a single turn, imbuing them with their strength, speed and skill. However, they pay a high price for this help, losing their own strength for the same amount of time. This Gift is taught by a wolf-spirit.
The player spends 2 points of Gnosis and states a period of time for the Gift to remain active. This could be "the next turn," "an hour," "the rest of the scene" or even "until the day I die." (If the Ahroun dies, the Gift ceases to work immediately, so "Until the Final Battle" won't work unless you survive to see it.) For that amount of time, one Garou of the Ahroun's choice and within their line of sight immediately is treated as possessing the Ahroun's Physical Attributes, Brawl, Dodge and Melee Abilities. (If the target should have higher statistics than the Ahroun, they retain those statistics.) However, the Ahroun is treated as having a mere one dot in all Physical Attributes, in all forms, as long as the Gift is active, and no dots in Brawl, Dodge or Melee. The target and the Ahroun cannot spend experience points to raise any of the shared Traits until the Gift ends.
