Cloudrest

You can Tank Cloudrest with any class however the Warden and Sorcerer are both excellent for this environment, and arguably make this trial much easier to Tank.

The Dragonknight is always an option due to their skills and passives.

Necromancer & Templar Main Tanks may find this trial difficult mostly because of the difficulty with healing while transitioning and in the portal.

Any race can be used on Cloudrest but there are some that will help more than others

Bretons are fantastic in this trial for the Magicka sustain since Magicka use is extremely high for Tanks in Cloudrest especially in the portal, plus you get really high Spell Resistance and the last boss is 100% Spell Damage.

Nord for the additional resistances, this really helps dealing with the high damage in the portals.

Imperial or Redguard for the sustain.

Orc for the extra healing and speed, both great for this trial.

The Steed is an excellent choice for the speed boost and Health Recovery. The speed boost is nice for Tanks that are new in here and struggle to get to the bosses quickly, and the Health Recovery great because we are stacking multiple sources which make us have up to 5k incoming Health per recovery tick.

If you are not stacking Health Recovery then The Atronach for the extra Magicka Recovery, there is a lot of Magicka casting for the Tanks in this trial so this is important to help with sustain.

The best option here is 64 Health since this build uses Pristmatic and Magicka glyphs and no Boundless Vitality CP but you still need 36-38k Max Health to help you survive the incoming damage from the portal.

As standard we use the Bewitched Sugar Skulls which gives us Max Health, Magicka and Stamina plus more Health Recovery which is helpful in Cloudrest.

If you are the execute Tank, it can be a good idea to have another type of food that you use as soon as you reach execute. This food will typically not have any Max Health perk and it means you and your Healers will be able to get you back to full Health during the Baneful Mark. Good food options for this are anything with Max Magicka, Magicka Recovery, Health Recovery and possibly Max Stamina.

You can use regular Tri-Stat potions here when you are dealing with the Gryphons or not in the portal.

When you are in the execute phase or you are in the portal you should use the Essence of Health potions that provide 8369 Heath, Major Fortitude, 898 Health per second and Major Vitality. In the portal you would use these when you have the orb dot especially or when you have really high damage phases and you are struggling to out heal it with regular heals.

In execute you would use these only when you have received the Baneful Mark and completed your rotation to reach full health and you have not reached full to remove the Mark, you use a potion and tell your healers and then spam as much healing on yourself as possible.

When you first come out of the portal you could use Immovable Potions if your group are fighting Relequen since that boss can stun you and make you get killed by the Monstrosity.
