Stamina Warden build with crafted sets and a vanilla monster mask.

Best race: Dunmer. Orc, Khajiit (slightly less damage), and even Wood Elf will also work. 64 points into stamina.
Food: for parsing: Lava Foot Soup-And-Saltrice. In content, you can use Braised Rabbit with Spring Vegetables for more HP and a bit more damage.
Potions: Essence of Weapon Power or Alliance Battle Draught (stamina regen, weapon crit, weapon power).

Opening:
Summon the bear ( Wild Guardian), cast Deadly Cloak, Arctic Blast, and Subterranean Assault away from the target, come closer, throw a trap (Barbed Trap), activate the ultimate Wild Guardian, then Stampede, Сarve, Winter's Revenge.
Then Fetcher Infection and Cutting Dive.

Rotation:
Every sixth skill you should use Subterranean Assault (you don't need to count, just cast it off cooldown). Next, prioritize your DoTs (damage over time skills).
Priority of DoTs - Carve (don't let the stacks drop), Stampede, Arctic Blast, Winter's Revenge, Barbed Trap, Fetcher Infection, Deadly Cloak, Cutting Dive. For convenience, I arrange the DoTs in order of importance from left to right on the bar, making it easier to track which to activate.
When all DoTs are active, spam Rapid Strikes. The Warden doesn't have an execute phase, so just maintain the rotation throughout the entire parse.
