This Gift is another of those that draws on the ancient alliance with Turtle, summoning an earth-spirit to rampage forth and crush things or people at the werewolf’s bidding.

Fertility spirits beholden to the Corn Maiden teach this Gift, by which a single chosen object can be multiplied into many duplicate objects. In this way, a warrior can make several arrows from one prototype arrow or more bullets from a single bullet. Any object with spiritual power (such as a fetish) cannot be duplicated. Anything else, from $20 bills to food can be multiplied using this Gift.
