Your spells channel positive energy to deal extra damage to undead creatures, but are less effective against other opponents.
Prerequisite: Non-evil alignment, must not have the ability to rebuke undead.
Benefit: Your spells are infused with positive energy. An energized spell deals an extra 50% damage to undead creatures, but deals 50% less damage to non-undead creatures and to objects. An energized spell uses up a spell slot one level higher than the spell's actual level.
Special: A character who has the ability to channel negative energy to rebuke or command undead cannot select this feat.
