Metamagic Feats

Heroic Metamagic [Metamagic]

Prerequisite: Any one metamagic feat, ability to cast 2nd level spells.

Benefit: By spending a hero point as part of the casting of a spell, you can augment that spell with any one metamagic feat that you know. Doing so does not increase the casting time, nor does it take up a higher spell level slot. However, the maximum spell level alteration from a metamagic feat that you can augment in this way is +1 per every four caster levels, to a minimum of +1. Thus, in order to use this feat to augment a spell with the Maximize Spell metamagic feat, you need to be a 12th level caster.
