I think I'm going to go with Rad. The only attack he used which I really found interesting was the greek chorus thing, and that didn't make sense tactically. I mean, Eurri came into the battle knowing nothing about his abilities; the first time he uses magic, therefore, he has the advantage of surprise... so he uses that element of surprise to provide some ambiance and distract Eurri slightly.
The spirit bomb itself couldn't have appeared more then a second before he used it, since there is NO way Faw could have hid a giant opaque energy ball three times the size of his head behind his body. Therefore, he could have just had the room lights turn bright blue and talked to distract Eurri from the fact that his hand was glowing. That series of actions would not have required the use of the greek chorus, and would have been more realistic anyway (it's not like it is in-character for Eurri to pay attention to what the greek chorus was singing anyway.)
