Subclass Tank Build - ESO Guide

• Shield Throw (Taunt, Sage's Remedy, Maim) - ranged taunt which will heal you and apply the Major Maim debuff for 10 seconds, which decreases enemies' damage done by 10%
• Trample (Magic, Thief's Swiftness, Heroism) - a 1.5 second channel that will grant you Major Heroism for 10 seconds which translates to roughly 20 Ultimate per cast. If you're using Baron Zaudrus, use Assassin's Misery instead to proc it more
• Siphoning Attacks - this ability will passively heal you and improve your sustain. It can also be used to trade Health for a burst of Stamina and Magicka
• Ulfsild's Contingency (Damage Shield, Gladiator's Tenacity, Resolve) - a damage shield for yourself and your teammates that also provides 8% damage mitigation for 8 seconds and Minor Resolve for 22 seconds, increasing armor by 2974
• Polar Wind - a very strong direct heal that also heals an ally and puts a 10 second HoT on yourself
• Temporal Guard - an ultimate we won't be using, but we'll keep slotted for the passive Minor Protection which reduces damage taken by 5%. It will also trigger the Concentrated Barrier passive
• Expansive Frost Cloak - a source of crucial Major Resolve buff for your entire group, which increases armor by 5948, which is roughly 12% damage mitigation
• Wield Soul (Pull, Druid's Resurgence, Cowardice) - a chain ability for stacking smaller adds that also restores 600 Stamina. It should also be used on unchainable enemies to apply the Major Cowardice debuff which reduces enemies' Weapon and Spell Damage by 430
• Elemental Susceptibility - a free ability that applies the crucial Major Breach debuff which reduces enemies' armor by 5948 and applies Burning, Concussed and Chilled status effects every 7.5 seconds. Concussed applies Minor Vulnerability for 4 seconds which increases enemies' damage taken by 5% and can trigger Off Balance when paired with Lightning Elemental Blockade from your Healer. Chilled applies Minor Maim for 4 seconds which reduces enemies' damage done by 5%. If you were holding an Ice Staff at the moment Chilled procced, it will also apply Minor Brittle for 4 seconds which increases enemies' Critical Damage taken by 10%
• Elemental Blockade - this ability will constantly apply the enchant of your backbar weapon, which in our case will be Crusher. It will also apply Minor Breach debuff to enemies who are Chilled which reduces enemies' armor by 2974, and they'll always be Chilled thanks to Elemental Susceptibility. It will also grant projectile-only damage shields to you and your teammates
• Soul Burst (Damage Shield, Anchorite's Potency, Courage) - a damage shield for yourself and your teammates that consumes a Soul Gem to grant 3 Ultimate to you and your teammates up to once every 5 seconds. It also grants everyone Minor Courage for 20 seconds, increasing Weapon and Spell Damage by 215
• Reviving Barrier - an Ultimate that grants you and your allies a massive shield and applies a HoT

If you need to slot something situational, replace Trample if it's a difficult fight, Siphoning Attacks if you don't need the sustain, or Soul Burst if you don't need Minor Courage

• Inner Rage - a replacement for Shield Throw for easier fights. You're giving up the 10% damage reduction and the heal from Shield Throw but you're providing an extremely strong synergy for your group. Also your default taunt when running double Ice Staff setup. It can also be used if you're struggling with Stamina, as it costs Magicka unlike Shield Throw
• Destructive Clench - use it if you're running double Ice Staff setup but still need Major Maim. It only lasts 5 seconds compared to 10 from Shield Throw, so only slot it over Inner Rage if you know your team needs the Maim (for example in Kyne's Aegis where you need to apply Major Maim before Instability goes off, and if you time it correctly the 5 seconds is enough)
• Revealing Flare - slot it for more difficult fights where you need more damage mitigation. It passively grants Major Protection, reducing your damage taken by 10%. It will also trigger the Magicka Aid passive, which increases Magicka Recovery by 10%
• Resolving Vigor - extremely strong HoT that can help you survive more difficult fights, which also provides Minor Resolve. It can be used to proc Powerful Assault set
• Echoing Vigor - alternative to Resolving Vigor which heals for a similar amount but over 16 seconds instead of 5. It now heals 6 allies (including you) instead of just you and doesn't provide Minor Resolve anymore. Use it to help your teammates survive in fights which are easy for you to survive. It can be used to proc Powerful Assault set
• Defensive Stance - an ability which grants you a damage shield and allows you to reflect the next projectile within 6 seconds. It also passively reduces your block cost and increases block mitigation by 10%. Use it in fights where you're blocking a lot or in fights where you can do a lot of damage by reflecting projectiles
• Immovable - use it in fights where you need lots of block mitigation or CC immunity
• Crushing Shock - use it in fights where you need to interrupt an enemy who's standing far away from you
• Shimmering Shield - use it in fights with dangerous projectiles
• Razor Caltrops - source of AoE Major Breach for trash fights or boss fights with lots of adds
• Pulsar - a skill that combined with Charged Ice Staff provides almost guaranteed AoE Chilled procs. Use it in trash packs
• Power Slam - a skill for proccing the Void Bash item set if you're switching to that in trash packs
• Race Against Time - use it in fights where you need snare removal. It also triggers the Concentrated Barrier passive
• Charging Maneuver - provides your entire group with a total of 45% bonus movement speed. Very useful in trash packs, but it consumes a lot of Stamina
• Exhilarating Drain - an extremely strong Ultimate generating ability which is locked behind being a Vampire, which will increase costs of all of your skills and increase your Flame damage taken even at the lowest stage. It can also be risky to cast in more difficult fights, since it's a channeled ability. Use it if you want to support your team even more and you can handle the drawbacks
• Aggressive Horn - an Ultimate which grants a 30 second buff which increases Max Stamina and Max Magicka by 10%, and 10 seconds of Major Force to your entire group. Use it if you want to focus more on group damage. It's especially useful when not using Saxhleel's Champion, since they both provide Major Force
