Arcanist 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%
• 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
• Energy Orb - an AoE heal which we'll use to trigger Ink-Scribe's Verve. It also grants our allies the Healing Combustion synergy which restores their resources.
• Trample (Magic, Assassin's Misery, Heroism) - can provide a lot of Ultimate generation, but the same buff can be provided by Wardens with Bountiful Harvest
• Impervious Runeward - an extremely strong damage shield for the first second and then a smaller one for the remaining five. It can also consume Crux to heal you for 10% Max Health per Crux spent.
• Gibbering Shelter - A defensive Ultimate that absorbs 60% of incoming damage for 10 seconds. When the shield absorbs damage, it shields up to 11 nearby allies for 4 seconds, up to once every 4 seconds. Both shields scale with Max Health. Use Glyphic of the Tides most of the time and Gibbering Shelter when under heavy pressure.
• Cruxweaver Armor - Your source of Major Resolve, increasing your armor by 5948. It also applies Minor Breach to enemies who hit you for 6 seconds and generates Crux when you get hit up to once every 5 seconds. It's also how you trigger Erudite's Rigor
• 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
• Runeguard of Still Waters - Grants Minor Resolve to you and your group members, immobilizes nearby enemies after 1 second, and gives you Minor Protection . The first time you take damage while below 50% Health, the Minor Protection is consumed to heal you for 30% Max Health.
• Glyphic of the Tides - An Ultimate that summons a glyphic we can heal with Energy Orb. It gives up to 200 Weapon and Spell Damage and healing around it based on its Health. At full Health, it also grants everyone Major Protection

If you need to slot something situational, replace Trample first, especially in difficult fights. Replace Soul Burst if someone else provides Minor Courage

• Runic Sunder - A 22 meter taunt that steals 2200 Armor, applies Minor Maim, generates Crux, and reduces your damage taken by 2% per active Crux while slotted. Use it if your team needs more penetration or if you need more armor.
• Exhilarating Drain - a 3 second channel that generates 20 Ultimate over its duration. If you're playing a Vampire, it can replace Trample when a Warden provides Major Heroism with Bountiful Harvest .
• Inner Rage - a replacement for Shield Throw for easier fights. You're giving up Major Maim 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, so only slot it over Inner Rage if you know your team needs the Maim
• 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
• Razor Caltrops - source of AoE Major Breach for trash fights or boss fights with lots of adds
• Pulsar - a skill that combined with a Charged Ice Staff provides almost guaranteed AoE Chilled procs. Use it in trash packs
• 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
• Power Bash - 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
