How does this look? I'm planning on trying to use it as pacifist arcane support. Mainly to try and give enemies Shaken, Entangled and Fatigued all at once via Rime Frostbite. For creatures immune to subdual (undead) or with reasonable cold resistance I wasn't quite sure where to go but I was thinking of grabbing Piranha Strike at 9 for extra damage. Many of the numbers are rough thoughts of where they'll be at. I know I'm going to have 11k or so to play with after +2 stat items and the +1 agile weapon.
