This build works great for trials, 4 man groups , also solo but missing damage so even though you will not die the fight will last awhile, great resource management, with all max magic glyths or all stat glyths , this build is currently running 5 piece Ebon and 5 piece plague doctors that works great together ,
Bar 1:
Heroic Slash: Debufs the enemy with minor maim, making sure they do 15% less damage. Will also give you minor heroism, increasing your ultimate gain.
Pierce Armor: Melee taunt that runs 15 seconds. Also debufs the enemy for 12 seconds with major fracture and major breach.
Hardened Armor: You major armor buffs that you need to keep up at all times. Will also give you a small shield.
Absorb Magic: Will give you 8% block cost reduction and 8% damage mitigation by having it slotted. Also handy to spam in heavy projectile fights, like Rakkhat in Maw of Lorkhaj.
Igneous Shield: A shield that scales with health (this is the essence of this build!) that goes on you and allies. Casting this will also give allies Minor Brutality and it will return stamina to you if you have unlocked the Helping Hands passive. This is a skill that you will constantly use.
Ultimate -> Replenishing Barrier: Now we DO NOT use this skill. but due to the alliance war passives having barrier slotted on your main bar will give you 10% extra Magicka recovery. Note that if you have issues bar swapping than please do not do this and just double slot war horn. It's not a huge difference, but min-maxing is min-maxing.
Bar 2:
Unrelenting Grip: Chains, pull enemies to you. A must have for every tank. Makes fights go way faster.

Inner Rage: A taunt that you can use on range to initiate encounters. It will cost magicka, but it also has a stamina morph. Which one you chose is a matter of personal preference.
Choking Talons: great for CC control and allies can activate Impale to deal 795 Magic Damage.
Energy Orb:
Guard (Mystic or Stalwart):
Igneous Weapons: = all these are changeable skills depending on your personal preference
Retreating Maneuver:
Green Dragon Blood:
Ring of Preservation:
balance
Deep Thoughts: An amazing skill for sustain which you can use during the less heavy parts of a fight for massive resource return. It is a toggle that drops block, but if you have the Deliberation passive you will gain major protection while meditating. Will also give you the Concentrated Barrier passive for being slotted.

2. Imperial -> 12% health is still a massive bonus that cannot be neglected.
