(General)
Your training in counterspelling summons is so extensive that you can redirect some of your foes' power to call forth your own allies.
Prerequisites
Spell Focus (conjuration) or counter-summons class feature.
Benefit
When you successfully counter a summoning spell with dispel magic or your own summon monster spell, you can immediately summon nonevil creatures as if you had just finished casting a summon monster spell of 2 levels lower than the countered summoning spell.
