 Pernicious Magic [Metamagic]
You gain a +4 bonus on caster level checks made to defeat a Weave user’s spell resistance. All creatures employing spells or spell-like abilities are considered Weave users unless they possess the Shadow Weave Magic feat. This benefit stacks with those from the Spell Penetration and Greater Spell Penetration feats, but it does not extend to spells you cast from the schools of evocation or transmutation.
