ESO Asylum Sanctorium Main Tank Build

Updated: Flames of Ambition (March 2021)

Information

Welcome to The Tank Club: ESO Asylum Sanctorium Main Tank Build.

Asylum Sanctorium is a DLC Trial located in Clockwork City. It was the first mini Trial in The Elder Scrolls Online and sixth overall trial.

These builds will work in standard vAS as well as the +1 and +2 Hardmodes. These builds are most suited to a Magicka Group composition, which is generally used by the majority of groups – however with some adjustments you could work this into a score pushing Stamina composition build.

We have included a range of options for Beginners, Optimised Groups, Advanced Groups and also a setup aimed at a Main Tank who wants to maintain Minor Brittle for their group.

From the Main Tank perspective this is possibly one of the easiest trials once you learn the initial mechanics of the trial. The boss attack hit hard but they hit very slowly, and there are times where you are not taking much damage and the boss isn’t hitting you for 20-30 seconds. Upon becoming experienced in this trial, there is very little for you to do other than block/roll dodge the swipes and then and maintain your abilities, buffs and debuffs.

Abilities

Dragonknight

Pierce Armor Heroic Slash Igneous Shield Green Dragon Blood Stone Giant Aggressive Horn
Inner Rage Overflowing Altar Elemental Blockade Balance Efficient Purge Barrier

Purge is a must have skill here. If you are hit by Olm Breath, Llothis Poison Cone or the Fire AoE in execute, all of these can be purged. You will also help your group remove the Fire DoT in execute which is a job for both the Main and Off Tank as they are the only people in range of all the group especially in Hardmode.

You use Blood Altar for the group synergy to help people stay alive during Kite. If this is not needed you can use Elemental Drain for the Spheres that enter the fight near you.

If using War Machine, slot War Horn front bar as you only need War Machine on 1 bar.

Stone Giant is pretty easy to maintain here, especially if you only get your Stagger active when the boss is being damaged by the group. For Beginners drop it for Cinder Storm to help keep you alive.

If you are using the advanced setup, make sure to use Elude to reduce the AoE damage.

Brittle setup, uses Inner Light to boost Max Magicka higher and Temporal Guard to reduce a little bit of the additional damage received by not using a Shield.

Necromancer

Pierce Armor Heroic Slash Avid Boneyard Hungry Scythe Empowering Grasp Glacial Colossus
Inner Rage Overflowing Altar Elemental Blockade Balance Efficient Purge Barrier

Purge is a must have skill here. If you are hit by Olm Breath, Llothis Poison Cone or the Fire AoE in execute, all of these can be purged. You will also help your group remove the Fire DoT in execute which is a job for both the Main and Off Tank as they are the only people in range of all the group especially in Hardmode.

You use Blood Altar for the group synergy to help people stay alive during Kite. If this is not needed you can use Elemental Drain for the Spheres that enter the fight near you.

If using War Machine, slot Colossus front bar as you only need War Machine on 1 bar.

Empowering Grasp is not going to be easy to maintain here but it will reach your group if they know how to do the fight correctly. During the Olms damage phases the group can come close enough to the boss for you to spam Grasp towards them and it will give them the Empower buff when they are damaging the main boss. Beginners can just slot Spirit Guardian for the extra recovery.

Brittle setup, uses Inner Light to boost Max Magicka higher and Temporal Guard to reduce a little bit of the additional damage received by not using a Shield. Mortal Coil is for an additional heal and a little Stamina gain so you can roll dodge easily, and you proc that by using the corpses from Spirit Guardian which also gives your more recovery.

Nightblade

Pierce Armor Heroic Slash Lotus Fan Dark Cloak Leeching Strikes Aggressive Horn
Inner Rage Overflowing Altar Elemental Blockade Mirage Efficient Purge Barrier

Purge is a must have skill here. If you are hit by Olm Breath, Llothis Poison Cone or the Fire AoE in execute, all of these can be purged. You will also help your group remove the Fire DoT in execute which is a job for both the Main and Off Tank as they are the only people in range of all the group especially in Hardmode.

You use Blood Altar for the group synergy to help people stay alive during Kite. If this is not needed you can use Elemental Drain for the Spheres that enter the fight near you.

If using War Machine, slot War Horn front bar as you only need War Machine on 1 bar.

The NB doesn’t really have useful group buffs, you could use Lotus Fan for Minor Vulnerability, this means the Healer would not need to use a skill that does this. For a Beginner just use Swallow Soul for an extra heal as the NB has no burst heal.

If you are using the advanced setup, make sure to use Elude to reduce the AoE damage.

Brittle setup, uses Inner Light to boost Max Magicka higher and Temporal Guard is not needed by Nightblades as they have Minor Protection from Dark Cloak so just use Incap for the extra sustain. Spell Symmetry is used rather than Balance because Nightblades already have Major Resolve from the Shadow Barrier passive.

Sorcerer

Pierce Armor Heroic Slash Dark Deal Summon Unstable Clannfear Efficient Purge Aggressive Horn
Inner Rage Overflowing Altar Elemental Blockade Balance Summon Unstable Clannfear Barrier

Purge is a must have skill here. If you are hit by Olm Breath, Llothis Poison Cone or the Fire AoE in execute, all of these can be purged. You will also help your group remove the Fire DoT in execute which is a job for both the Main and Off Tank as they are the only people in range of all the group especially in Hardmode.

You use Blood Altar for the group synergy to help people stay alive during Kite. If this is not needed you can use Elemental Drain for the Spheres that enter the fight near you.

If using War Machine, slot War Horn front bar as you only need War Machine on 1 bar.

No difference skills to use with Standard and Beginner as your group buff comes from Dark Deal which happens to be an excellent sustain skill. Make sure to use this immediately after Olms has Swiped you, when using Dark Deal it drops block for 1 second so if you time it wrong you’ll die.

If you are using the advanced setup, make sure to use Elude to reduce the AoE damage.

Brittle setup, uses Inner Light to boost Max Magicka higher and Temporal Guard to reduce a little bit of the additional damage received by not using a Shield. Switch Dark Deal to Dark Conversion so you can maintain the group buff without wasting Magicka.

Templar

Pierce Armor Heroic Slash Extended Ritual Radiant Ward Power of the Light Aggressive Horn
Inner Rage Overflowing Altar Elemental Blockade Restoring Focus Efficient Purge Barrier

Purge is a must have skill here. If you are hit by Olm Breath, Llothis Poison Cone or the Fire AoE in execute, all of these can be purged. You will also help your group remove the Fire DoT in execute which is a job for both the Main and Off Tank as they are the only people in range of all the group especially in Hardmode.

You use Blood Altar for the group synergy to help people stay alive during Kite. If this is not needed you can use Elemental Drain for the Spheres that enter the fight near you.

If using War Machine, slot War Horn front bar as you only need War Machine on 1 bar.

Power of the Light can be applied to the Mini Bosses and Spheres for activating both the Templar group buff Minor Sorcery and Minor Breach. You can also put down Extended Ritual which will overlap to your group and give them the Purify Synergy which means you won’t need to cast Purge as much in execute as the group and grab the synergy from Olms tail. For Beginners you could drop Ritual which gives you healing in place of Radiant Aura which passively gives you more recovery and sustain, but using either Aura or Ritual are both good options. You could also switch Power of the Light to Purifying Light for extra healing.

If you are using the advanced setup, make sure to use Elude to reduce the AoE damage.

Brittle setup, uses Inner Light to boost Max Magicka higher and you don’t need Temporal Guard on a Templar as they already have Minor Protection from the Spear Wall passive. Spell Symmetry would be used because you already have Major Resolve from Channelled Focus. You should use Power of the Light with Elemental Drain as it’s basically the same as using Pierce Armor.

Generally the Templar self healing is very weak for a Heavy Armor Tank, so use Radiant Ward when you are about to receive damage and this will give you a huge shield, basically you just try not to take any damage to your health by using this and therefor you never need to heal.

Warden

Pierce Armor Heroic Slash Energy Orb Polar Wind Fetcher Infection Aggressive Horn
Inner Rage Overflowing Altar Elemental Blockade Expansive Frost Cloak Efficient Purge Barrier

Purge is a must have skill here. If you are hit by Olm Breath, Llothis Poison Cone or the Fire AoE in execute, all of these can be purged. You will also help your group remove the Fire DoT in execute which is a job for both the Main and Off Tank as they are the only people in range of all the group especially in Hardmode.

You use Blood Altar for the group synergy to help people stay alive during Kite. If this is not needed you can use Elemental Drain for the Spheres that enter the fight near you.

If using War Machine, slot War Horn front bar as you only need War Machine on 1 bar.

Use Healing Orbs here and cast them through the middle of Olms when the group is in close during the Olms damage phase, this is to proc your Maturation passives that gives Minor Toughness. You also should use Fetcher Infection for the Minor Vulnerability, ideally use this on all enemies that are within your range. For beginners you could drop Orbs for Netch to help you with sustain but this means the group won’t get the Max Health buff.

If you are using the advanced setup, make sure to use Elude to reduce the AoE damage.

Brittle setup, uses Inner Light to boost Max Magicka higher and Temporal Guard to reduce a little bit of the additional damage received by not using a Shield.

Notes

Main Tank Gear

The main boss only hits you once every 5 seconds and does a lot of mechanics that you avoid such as the Breath and Heaven. This makes Sturdy gear unnecessary on this fight, so if you have alternative traits you would have more benefit from Well-Fitted for roll dodging or Divines. If you are a beginner, then Sturdy will still be good since you’ll likely spend more time blocking.

You can use whatever glyphs you want for this, however you’ll get the most benefit from full Prismatic Defense.

3 Infused/Magicka Recovery works well here for frequent casting. For beginners 3 Triune/Magicka Recovery will give you a lot more resources.

There is not a lot of damage in this trial, but the things that do damage cause a lot of damage so going 7 Heavy is a good idea.

Beginner Group Main Tank Gear

Yolnahkriin is needed by the Main Tanks for the easy to maintain group buff and they are the only people taunting stuff 100% of the trial for maintaining the buff.

For the second set Worm is best for both your own sustain and your group sustain.

Monster Set to use would be Lady Thorn, this should be activated by using Balance or Altar as Storm the Heavens mechanic is starting, while Olms is jumping or when Olms is creating the Fire AoE in execute, this will debuff the boss and reduce the damage for your group.

Optimised Group Main Tank Gear

You would need to use Yolnahkriin still for this type of group.

For the second set you would use War Machine. The reason for this is because in vAS the Healers are too far away from group to use Roaring Opportunist so having both Tanks in War Machine will help resolve this problem. You only activate this set by using your Ultimate when Olms isn’t being shielded and your group is close to the boss.

Monster Set used would be Encratis’s Behemoth since it will increase your groups flame damage by 5%. All you need to do is Pierce Armor, Heroic Slash, Light or Heavy Attack the boss to proc your Infused/Flame Glyph on the front bar and this will proc the set.

War Machine is only needed on 1 Bar so you might as well front bar War Machine and use the Maelstrom Destruction Staff on the back bar to add a little bit of extra damage. You could also back bar War Machine with the Master One Hand and Shield on the front bar for more healing but this shouldn’t be necessary.

You could also use Elemental Catalyst as the Main Tank but you would need to build for it depending on what Class you are. You need to cause Fire, Shock and Frost damage every 3 seconds so it can be tricky for certain classes.

Advanced Group Main Tank Gear

Same setup as the Optimised Group Gear but you switch the War Machine to the body so you are using Medium and that allows you to do more damage.

Switch the Maelstrom staff to a bow.

Double Frost Staff Main Tank Gear

We can easily use an Ice Staff for Tanking this trial, so we use a Double Ice Staff setup along with Frozen Watcher.

It’s important to have a Charged Ice Staff front bar, when you press block it will cause Chilled and Minor Brittle almost instantly every single time while using Frozen Watcher.

When using an Ice Staff setup you will need to run full Sturdy with some things to increase Max Magicka as your Magicka drain becomes very high and it can be hard to sustain. Magicka Recovery is useless when using the Tri-Focus passives and I suggest using that passive when using double Ice so it’s better to use Reduce Magicka cost, and having an Infused Bracing also helps.

Race

The best Race’s to use here are:

  1. Imperial for overall sustain and cheaper Ultimate cost.
  2. Orc for extra damage and an auto-heal every 4 seconds.
  3. Redguard for Stamina sustain.
  4. Nord for lower CP players for additional resistances and mitigation.

Mundus

The best Mundus Stone to use here is:

  1. 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.
  2. The Lord for additional Health if you need it.
  3. The Mage for more Max Magicka if you are a DK using Engulfing or a Frost Staff Tank.
  4. The Steed for Health Recovery and additional speed if you need it for running into group during Olms breath to cast group buffs/Aggressive Horn.

Attributes

The Swipes hit hard and we can take some high combo damage during Heavens so put all 64 into Health.

Food

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

Potions

Regular Tri-Stat potions work fine here as they give all 3 resources and recoveries which we need for Tanking.
