This is my Solo Stamina DK (build by LuckyGhost)

Ideal Races: Dark Elf/Khajiit ( I have a Nord)
Alliance (does not matter)
Buff Food: Lava Foot Soup and Saltrice
Potions: For Easy content use Essence of Stamina Potions, for challenging content use Essence of Weapon Power

---If Playing in a Group---
Mundus: Lover --> Thief
Shoulder Piece --> Slimecraw - Medium - Legendary - Divines - Glyph of Stamina
Ring of the Pale Order --> Pillar of Nirn - Mythic - Bloodthirsty - Glyph of Increase Physical Harm

If you don't want to get Perfected Coral Riptide Gear because it's Veteran Trial gear replace it with Venomous Smite

---Rotation---
Prebuff with 3x Flames of Oblivion for 3x stacks of Seething Fury as well as Volatile Armor

Now you can enter combat and apply Dots:
Venomous Claw -> Noxious Breath -> Deadly Cloak -> Stampede -> Carve -> Barbed Trap

Now spam Molten Whip! Make sure to light attack weave between each ability for max DPS, keep your Dots up and don't forget to use your Essence of Weapon Power when you can (in challenging content)!

Ultimates:
Use Dawnbreaker for huge burst damage and to restore resources
Use Standard of Might for big buffs to your Dots, make sure you have applied your Dots before using this for maximum DPS!
