I would recommend something like this:
ƒ‹ƒjƒA戦‹L - ƒXƒLƒ‹ƒVƒ~ƒ…ƒŒーƒ^
Ice Dragon Heart does a lot more damage than you think o:
Level 2 Ice Meteor thingy doesn't really do much, if you do not consider on using it for damage, you could just put 1 point on it for large mob knockdowns, or even completely drop it.
The Ice Orb thing I took out has really little use, it freezes for less than a second, and I don't remember it working on bosses....
I also took some points off some of the skills, so they only have enough points in them for the damage bonus for 65+.
