The build is fairly simple. Here are some key points.
The rotation:
Keep up Deep Fissure as the second pop happens, keep up your damage over time skills, keep up your heal. When all of that is done, spam Force Pulse.
Important: Never activate your ultimate. The bear deals excellent passive damage without activating him, and this allows us to utilize the ultimate-for-health recovery champion point node giving us excellent passive regen at around 2-3k health recovery.
Final notes: My build on the live server is on a nord which is not optimal. If you use a breton for this build, you can change the magicka recovery glyphs to spell damage glyphs and you will have significantly more damage that way, though you will sacrifice some survivability without the extra armor and health that the nord gets.
