Greater Spell Penetration

(Player's Handbook v.3.5, page 94, DnD 3.5)

[General]

Your spells are remarkably potent, breaking through spell resistance more readily than normal.

Prerequisite

Spell Penetration

Benefit

You get a +2 bonus on caster level checks (1d20 + caster level) made to overcome a creature's spell resistance. This bonus stacks with the one from Spell Penetration.
