Bane Spell (3.5e Feat)
From D&D Wiki
Bane Spell [Metamagic]
Deal double damage to specific types of enemies.
Prerequisite: Any other metamagic feat
Benefit: You may choose one type of creature and gain extra damage against it. Any variable, numeric affect is doubled when the chosen type is the target. For instance, a Bane Spell (dragon) magic missile would deal 2d4 + 1 per bolt against dragons. A Bane spell takes up a spell slot two levels higher than the spell's normal level.
Normal: A magic missile would deal 1d4 + 1 per bolt.
Special: This feat can be gained multiple times, each time for a different type of creature.
