Merciful Blow (Rank 3) Edit
The Garou can subdue a foe in combat without harming him. This Gift is taught by a Mongoose spirit.
The Garou spends one Gnosis point, attuning himself to the body of his foe. If his next blow (hand or weapon) strikes and does damage before a soak is rolled, the Garou may then roll Perception + Medicine (difficulty of the opponents Wits + Dodge). One or two successes on this roll cause the opponent to keel over helpless for the next turn; three or more paralyze the foe for the entire scene.
