Hmm I like these changes.
Can I add that they also should increase the potency of the finishers.
Verflare/holy potency increased to 800 and scorch to 900.

About the aoes, verthunder/aero 2 and impact are kinda fine, maybe that we get an aoe-finisher for moulinette, like using maybe after using it 4 times that we can cast an aoe called verfoul which has a potency of 450.
