The Garou can take Renown from someone by hitting him.
The Garou makes a normal attack maneuver (punch, kick, club, etc.), and spends a Gnosis point, but must do no damage; roll damage as normal, but if any gets through the target's soak, this Gift will not work. The Garou can declare that he is pulling his blow and do no damage, but his attack difficulty is one higher. For every success (as long as no damage was done) the target loses 25 Glory Renown. This can only be performed on a single target once per scene. Every time this Gift is used against a Wyrm creature, the Garou gains 25 Glory Renown for every success on his roll, for being so bold as to strike a Wyrm creature but do no damage (he can hit it again afterwards and do damage if he wants). This can only be done once per battle with Wyrm forces.
