Metamagic Mastery [Metamagic]
When you use a Metamagic Feat on a spell that causes you to use a spell slot higher than the spell normally would use, you may reduce the spell slot level by one.
Example, Quicken Spell normally uses a spell slot 4 levels higher than the spell normally would use. With this feat, it would only use a slot 3 levels higher. Silent Spell (normally uses 1 spell slot higher) would use the normal spell level.
Considering the scarsity of FEATS for spellcaster types, I dont think this one is too powerful.
Anyone wanting to tone it down could rule that it only effects one spell school. You can take the feat multiple times but you choose a different school.
