Need Help with my Build

Trying to figure out how to get more DPS out of this Ol' Grandpa Freeze, and would like to use Arctic Breath, Freeze Pulse, Ice Nova, or Glacial Cascade. The idea is to perma freeze mobs, and unfreezable mobs quickly. Here is the build I have so far.

The change I was thinking of making was to this tree.

Not sure which one would do more dmg. Any Help would be greatly appreciated.

This is my current equipment just so people know.
