Strike of the Wolf (General) [Way of the Ninja (pg 22)]You can topple an opponent with a well placed sneak attack.Prerequisites: Base attack bonus +1 or higher, sneak attack ability.Benefit: Instead of inflicting extra damage with a sneak attack, you may attempt to topple youropponent instead. Roll your sneak attack damage dice normally. Instead of inflicting damage, your opponentmust make a Reflex save (DC 10 + your Dexterity modifier + the number of sneak attack damage dice youwould have added to the damage roll). If he fails this save, your opponent falls prone.An opponent suffers a -4 penalty to his saving throw per size category smaller than you, gains a +4bonus to his saving throw per size category larger than you and receives a +4 bonus if he has four legs or isotherwise unusually stable.Special: This effect is applicable to opponents that would normally not be damaged by a sneakattack due to immunity to critical his, but not against opponents who are immune to sneak attack due to theuncanny dodge class ability.
