You can modify a spell that uses energy to deal damage to deal subdual damage instead.
Prerequisite: Any other metamagic feat, 5 ranks in Knowledge (arcana)
Benefit: Choose one type of energy: acid, cold, electricity, fire, or sonic. You can modify a spell with the chosen designator to inflict subdual damage instead of energy damage. The subdual spell works normally in all respects except the type of damage dealt. For example, a subdual fireball spell works in the usual way, but the subdual fireball deals subdual damage instead of fire damage. A subdual spell uses a spell slot of the spell's normal level, modified by any other metamagic feats.
