Greater Spell Penetration
( Forgotten Realms Campaign Setting, p. 35)[General]
Your spells are especially potent, defeating spell resistance more readily than normal.
Prerequisite
Spell Penetration (PH) ,
Benefit
You get a +4 bonus on caster level checks (1d20 + caster level) to beat a creature's spell resistance. This overlaps (does not stack with) the bonus from Spell Penetration.
