Say I'm a 12th level Magi with Empowered and maximized arcana. Can I use both on a single spell? They both say you can cast one spell as if it were modified by the feat and they each are limited to once a day and one can combine meta magic feats if they have the levels to. Aside from not mentioning they can be used with another, and both referring to a single spell, I Don't see why they couldn't be. Thoughts?
