Relentless Focus when stacks are ready. With it being Stamina Based, it will alleviate some Magicka sustain issues during Global Cooldown. Keep [Essence of Health] pots on at all times for even more sustain (they're cheap, just use them).
Very easy rotation, keep Critical Surge up at all times, use Ulfsild's Contingency when you need extra shielding. The rest is pretty easy to figure out while weaving Light Attacks, with a few Heavy Attacks needed in long fights (even with Potions, sadly).
This build is not designed for top-tier parsing on a dummy, but more for those that don't like squeezing into sweaty Trials and want a very casual experience that gives very decent damage with excellent survivability.
