Pure DK Basalt-BW Healer (Trials) - Chevalier-dragon Construire PvE - ESO

This build with off meta DK class set is intended for Trials (normal, veteran and most veteran HM). It‘s overkill for Group Dungeons. It‘s all about fast Ultimate build up, and massive Damage Shields so it‘s good for progression veteran trials, too. It's not for leaderboards' runs as Basalt-Blooded Warrior set is not meta.

Igneous Weapons should always be up. Cast Fragmented Shield every 10 sec to grants you a Rock Stance. Target Fire Keeper on DDs to trigger Major Courage from Olorime set. 

Jewerly & front bar weapon: In any semi-competent group, Vestment of Olorime is going to perform way better than Spell Power Cure for Major Courage buff. However, DDs in normal PUG trials occasionally run like the headless chickens, and you can't do anything about it, but most of them are relatively easy, so no big deal ;-).

Back bar weapon: You don't need Inferno Crushing Wall (aka Maelstrom Inferno Staff), you can use Lightning version, too if you don't mind DK fire theme. They are used to provide a bit of more damage. However, you can equip Olorime Inferno or Lightning Staff, too as it has one major advantage - every time you cast Elemental Blockade, and Olorime is not on cooldown, it will trigger circle of might. This option is better in PUG runs from my experience.
