Jam Weapon (Rank 1) Edit
The Garou may stop any Weaver-born weapons from working within the range of his voice. A dove-spirit teaches this Gift.
The Garou shouts a single, strange word and spends a Gnosis point. The player rolls Perception + Expression, difficulty of the Willpower of the nearest armed person. For each success, all manufactured weapons will not function for one combat round. This includes guns, crossbows, flame-throwers, and even tasers or cattle prods (anything with moving parts). It does not include natural weapons (retractable claws don't count as moving parts).
