I was wanting a bit of clarification, as I have seen some blasting based builds using Ultimate Magus.
Augmented Casting essentially means you can only ever have 1 meta-magic attached to any spell you cast with it correct?
Thanks for the help!
All it says is that "you can't use this ability to augment a spell
already affected by a metamagic feat." So if you apply augmented casting first and then additional metamagics afterwards, you might be able to.
It's a bit of a rules twist, but you
could rationalize that it's not "already" affected when you apply Augmented Casting, therefore, you could add metamagics *after*.
I'd say ask the DM for an interpretation.
