The idea around this build was to build around strength and duration. Strength to increase the strength of his armor strip and duration for his 3 and whatever ability you decide to put on his 1 if you do. I decided to run arcane [Guardian] and arcane barrier for the tankiness, I found with how much [Regen] you get from his 3 I rarely have energy issues. You can also swap out the arcanes for any that increase your weapon damage for more dps.
