Although I later found out about similar builds, I actually came up with this myself.
This build serves me well doing Grifts, Bounties, and Ubers on high Torment levels. It's pretty easy to play, just keep your three triumvrate stacks up with magic and keep enemies at a distance and in your slow-time bubbles. Then just nuke with frozen orb.
-With the Ring Of Royal Grandeur you can either replace your gloves with Frostburn or your helm with the Crown Of The Primus. The other one you can use the cube to get the power of.
-The recommended belt really helps you keep your triumvrate stacks up and zap away the cooldown on slow time.
-You can replace "Energy Armor" with whatever you want. I've switched it out a few times, I just go with energy armor for the bonus arcane power, giving me an extra frozen orb cast.
-This build only really uses Frozen Orb for damage, so stacking bonus cold damage on your gear is a good idea.
-No convention of the elements because this is meant to be a simple, single-damage-type build.
