That'll do.
Suggestions for the two replacement feats for fire elemaster?
Quicken SLA with ray of frost and water breathing, obviously.

No, even better, Quicken SLA (water breathing) and Energy Resistance (fire).

Actually, Energy Resistance (sonic) is of some use, although I'm not sure how it'd fit thematically.
Maybe Epic Prowess and Hold the Line?
Oh, I've had an idea - what do you think about swapping the Airmental's extra Epic Prowess for Superior Expertise? An ultra air spirit ought to be good at evading attacks, and it means we're giving a bit more offence to the Fire, defence to the Air.
