DK TANK with infinite sustain - Dragonknight Build PvE - ESO

Bloodlord's Embrace + DK's passive Combustion will give you tons of free sustain. 
In order to proc Bloodlord's Embrace mythic you need to bash an enemy. With combination of Turning Tide set your bash will also apply major vulnerability, which you can extend by your monster set nazaray(together with brittle!)

On your one hand you have charged trait + poison glyph which will proc poisoned status effect and this will restore 1000 stamina thanks to Combustion DK passive.
With Elemental susceptibility you proc burning status  effect  + other effects(brittle, minor vulnerability) which restores 1000 magicka. 

With Helping Hand passive you basically convert your magicka to your stamina. Casting Igneous shield grants you 1120 stamina.
