Tank Tier List

Every tank build on the site, including each subclass variant, ranked by what it does for itself, the group and the boss. Every point traces back to a buff, its uptime and its damage value.

Update 5110 buildsUpdated 2026-10-21

How to read it

Each build earns points in three categories, scored out of 100 against the best build in that category. The overall score weights them 40% self-survival, 40% group buffs and 20% enemy debuffs: staying alive and buffing the group matter equally. Dragonknight comes out on top with 89. Open any build below to see every effect it brings, where from, for how long, and the points it earns. The full method is at the bottom of the page.

Self-survival and sustain

What keeps the tank alive and casting: Resolve, Protection, Evasion, recovery and class passives. This counts for half of the overall score, because a dead tank buffs nobody.

How it's scored

The list starts from the buffs and debuffs each build brings in its Boss setup (taunting with Goading Throw), then adds the skills any class can slot, so classes are compared on what they can reach, not just on one set of bars. Each effect earns value × weight × uptime points (halved for group buffs healers usually bring), and a category's points are added up.

Value is the effect's Impact from the Buffs & Debuffs reference: Major Protection is 10 points for 10% less damage taken, Major Breach is 12.4 for 12.4% more damage on a boss, and so on. Effects without a damage percentage get the fixed values listed below.
Weight is how much of that value really lands, from the effect weights. Capped stats like Critical Damage and Penetration are worth less, since groups often hit the cap anyway.
Uptime is how much of a boss fight the effect is up, from the rules below. Two sources of the same effect don't stack, so the effect counts as up whenever either source is (for example, 45% Archdruid plus 50% Colossus is 73% Major Vulnerability).
Category score is the build's points divided by the best build's points in that category, out of 100.
Overall is 40% self-survival + 40% group + 20% enemy. Subclass builds keep 92% of it: subclassing turns off Class Mastery, and in an organised group a pure-class tank is still the stronger pick.
Tiers:S 90+A 75+B 60+C below 60

Effect weights

Two effects with the same percentage aren't worth the same. Protection cuts every hit, while Evasion only cuts area damage, and Critical Damage or Penetration past their caps does nothing. Each effect's value is multiplied by its weight. Effects not listed here count in full.

Major Protection, Minor Protection	×1	Cuts all damage taken and multiplies with every other defence.
Major Resolve, Minor Resolve	×1×0.6 on you	Damage dealers sit far below the 33,100 armor cap, so they get it all. Tanks are close to the cap in heavy armor, so much of it is wasted on you.
Illuminate	×1	Armor for damage dealers, who are far below the cap.
Major Vulnerability, Minor Vulnerability	×1	Uncapped and multiplies with everything else.
Calculated Defense	×1	Only Sorcerers have it, so nobody else covers it, and it stacks with every other Weapon and Spell Damage buff.
Cutthroat's Focus	×1	Works like extra Vulnerability: uncapped and multiplies with everything else.
Major Brittle	×1	Critical Damage, but only Wardens apply it reliably, so it's how a group reaches the cap rather than wasted past it.
Major Maim, Minor Maim	×0.9	Only the debuffed enemy's damage, but on a boss that's most of it.
Major Slayer, Major Berserk, Minor Berserk	×0.9	Uncapped, but adds to other damage done bonuses rather than multiplying.
Minor Brutality, Minor Courage, Powerful Assault	×0.8	Adds to a large Weapon Damage pool, and damage dealers often self-buff Major Brutality.
Major Breach, Minor Breach, Exploitation	×0.6	Penetration caps at the boss's 18,200 armor. Groups usually reach it with Crusher, Alkosh, Tremorscale and CP, so extra is wasted.
Major Force, Minor Force, Minor Brittle	×0.5	Critical Damage caps at 125%. Groups reach it easily with Lucent Echoes, Force, Brittle and passives.
Major Evasion	×0.35	Only area damage. Boss hits that threaten a tank are mostly direct.

Skills any class can slot

These come from non-class skill lines (Psijic Order, Scrying, Assault) and scribing, so every build gets them. When a build already has a class source for the effect, the better of the two counts, since you wouldn't slot both. Bow and two-hander grimoires such as Vault aren't counted, because a tank carries a sword and shield and an ice staff. Each of these costs a bar slot, so a class source for the same effect still frees a slot for something else.

Major ProtectionFor you	Revealing Flare · Slotted (front)	100%
Major ResolveFor you	Wield Soul (Resolve affix) · 10s	80%
Minor ResolveFor you	Resolving Vigor · 20s	95%

Major ForceFor the group	Aggressive Horn · 10s (Ultimate)	20%
Minor CourageFor the group	Soul Burst (Courage affix) · 20s	80%

Group buffs other roles usually bring

A tank that brings a buff the group already has adds little, so these count for part of their points in the group category: a quarter when damage dealers can cover it themselves (with potions, for example), half when healers usually bring it. Buffs that only tanks or one class usually bring, like group Major Resolve, Minor Brutality (Dragonknight only since Update 51; potions give Major Brutality, which stacks with it), Exploitation or Illuminate, count in full.

Major Force	×0.25	Since Update 51, Force potions give it, and healers keep it up with Aggressive Horn, Saxhleel Champion or Ink-Scribe's Verve.
Major Slayer	×0.5	Healers usually bring it through Master Architect or Roaring Opportunist.
Minor Heroism	×0.5	Healers and damage dealers bring it through Hearth and Home, Heroism potions and many sets.
Minor Courage	×0.5	Healers bring it through Zenas' Empowering Disc, Spell Power Cure, Vestment of Olorime and similar sets.
Minor Fortitude	×0.5	Healers bring it through Radiant Aura, Zenas' Empowering Disc and Hearth and Home.
Minor Intellect	×0.5	Healers bring it through Radiant Aura, Zenas' Empowering Disc and Enchanted Growth.
Minor Endurance	×0.5	Healers bring it through Radiant Aura, Zenas' Empowering Disc and Enchanted Growth.

Uptime rules

Passive or slotted	~100%	A passive, or a skill that works while slotted. Front-bar-only skills like Revealing Flare count too, because tanks fight from the front bar.
Kept up	~95%	A 20 second or longer effect you recast before it drops.
Short recast	~80%	10 seconds or less, so a missed GCD drops it.
Allies must stand in it	~60%	Ground areas and pickups that need the group to be in the right place.
Proc on a cooldown	~45%	Duration divided by the cooldown, e.g. 7 seconds every 15.
Ultimate	~20%	About one Ultimate every 45 to 60 seconds, so a 10 second effect is up about a fifth of the time.

Each source in the breakdowns says which rule it follows and why, and some are adjusted for the skill (a 6 second proc on projectiles, a heal that only lands on allies nearby).

Fixed values

These effects have no damage percentage, so they get a judgement-call value in the same points.

Major Cowardice	2	430 less Weapon/Spell Damage barely moves monster damage.
Minor Cowardice	1	215 less Weapon/Spell Damage.
Major Fortitude	3	30% Health Recovery: steady healing, not mitigation.
Minor Fortitude	1.5	15% Health Recovery.
Minor Intellect	1.5	15% Magicka Recovery.
Minor Endurance	1.5	15% Stamina Recovery.
Major Heroism	4	3 Ultimate every 1.5 seconds: more Colossus, Horn and Barrier casts.
Minor Heroism	1.5	1 Ultimate every 1.5 seconds.
Major Expedition	1	Movement speed only.
Major Vitality	4	12% more healing and shields received, about a third as strong as 12% less damage.
Burnished Scales	3.8	Damage blocked +10% (see the block model).
Resolute Defense	11.3	Damage blocked +30% after 5 seconds of holding block (see the block model).
Bound Aegis	17.3	Damage blocked +50% for about 3 seconds per cast, which reaches the 90% block cap (see the block model).
Pound of Flesh	2	Small random heals and Stamina when hit.
Green-Keeper's Hide	9	3% less damage per status effect on the attacker; the ice staff keeps about three on a boss.
Calculated Defense	3	For you: a 0.5 second shield worth about 5,280 on every Sorcerer cast. The group's 6% Weapon and Spell Damage uses its damage value.
Conservation of Energy	2	A little heal and resources on every cast.
Bright Harbinger	3.4	300 Weapon and Spell Damage for the group while Illuminate is up, valued like any other damage buff.
Steadfast Candescence	7.5	Damage blocked +20% while standing still (see the block model).
Devout Guardian	3	A recurring shield that adds recovery while it holds.
Share the Spoils	3	Ultimate, Magicka and Stamina for the group on Siphoning casts.
Siphoning Attacks	4	Sustain: 200 Magicka and Stamina a second (more than Minor Intellect and Endurance together) plus 1,250 Health a second while you deal damage.
Transfer	2	About 1 Ultimate a second from Transfer and Catalyst, half of Major Heroism.
Bull Netch	3	A cleanse every 5 seconds (removes damage over time and other negative effects) plus Stamina Recovery.
Budding Seeds	2	A strong group heal over time that blooms for a burst; tanks rarely bring group healing.
Streak	4	Positioning and speed: an instant gap closer that stuns every add on its path, so you reach and gather packs faster.

Block model. Block bonuses count as less damage taken. A sword and shield tank already has +24% damage blocked (Sword and Board, Fortification) and 5 heavy pieces, so a block stops 67% of a hit. Block bonuses multiply the 50% base and cap at 90%. About 50% of a tank's incoming damage is blockable boss hits, so a bonus is worth the share of total damage it removes: +10% is 3.8, +30% is 11.3, and Bound Aegis's +50% reaches the cap for 17.3.

What it doesn't capture

Resolve is worth less once you're near the 33,100 armor cap. With a medium head and light shoulders, most tanks land just under it. The list scores it at its full 9% like the reference does.
Passives from non-class lines that every class gets the same (heavy armor, Undaunted, the staff and shield lines) cancel out, so they aren't listed. Class passives like Shadow Barrier and Exploitation are.
Gear is swappable. The scores use each build's default sets (Archdruid Devyric, War Machine, Void Bash, Powerful Assault...), and the gear picker on each build changes what you bring.
Shields and heals from skills (Reviving Barrier, Regenerative Ward, Polar Wind) aren't buffs, so they only count through the Major and Minor effects they give. A shield-heavy build is a little stronger than its score.
Group utility that isn't a buff, like pulls, stuns and synergies, isn't scored. Neither is how hard a build is to play.
