At this point, with 3 points in FM
Lv 10 meteor = 472 - 501, 178-212/sec
Lv 13 Fire wall = 999 - 1032, 20.6 yard
Lv 18 Fire Ball = 257 - 269.

But the point isn't really to kill with those skills. The character graphic is changed, and you should still be able you poison nova, bone spirit, revive etc.

Just like how other full sets give you the Valk's glowing animation...and nothing else.
