Ohh let me show you my Cryomancer on PTS ;P
I used Elsa's coronation dress as inspiration instead of her iconic ice dress because I really couldn't make it look anything like her ice dress.
Either way... She is a classless cryomancer, meaning she is a RP character that doesn't use class skills, only destruction/restoration staves and mages guild skills. The lack of frost-based class skills never bothered her anyway.
