Family Debt (Rank 5) Edit
This Gift allows the player to call upon the ancestor-spirits of other tribes, provided they owed the Glass Walkers (or historical incarnations) a favor before their death. The Gift requires a Garou from the same tribe as the Ancestor spirit being called to be present (the "guest"), and that Garou must have the Ancestors background. The Gift is taught by any long-lived spirit, such as a turtle- or elephant-spirit, and often a similar spirit is called upon to bear witness to any agreements made between the Glass Walkers and the ancestor-spirit.
Glass Walkers of the Wise Guys camp can learn this Gift.
The Garou spends one Willpower point and rolls Gnosis. The difficulty is 10, minus however many dots of Ancestors Background the guest possesses. If successful, the summoned ancestor literally possesses his descendant, and can negotiate the terms of repaying the debt.
