ESO Update 50 goes live on June 8, 2026 across PC, Mac, PlayStation, and Xbox as part of Season Zero. This is not a small patch. ZeniMax is shipping a brand new Class Mastery passive system, sweeping adjustments to almost every class ability that matters in group content and solo play, a full Werewolf overhaul, and a wave of item set reworks that flip several top-tier damage bonuses from multiplicative to additive. If you have a meta build right now, some of it will feel different the moment servers come back up.

Before you log in, here is exactly what changed, which classes benefit most, which ones took a hit, and what you should test first.

What Class Mastery Actually Does to Your Build

Class Mastery is a new passive skill line available to characters who keep all three of their native class skill lines and do not use any subclass options. Once you qualify, you receive two Class Mastery Points (not regular Skill Points) and can spend them on two passives from a pool of five unique options tied to your class.

The system is designed to create a real trade-off. Subclassing gives you flexibility and access to off-class skills. Going pure class now gives you power passives that are not available any other way. ZeniMax has flagged these values as likely to be adjusted over time, so expect some of the numbers to shift in future updates.

If you swap any native class skill line for a subclass slot, your selected Class Mastery passives deactivate automatically and refund until you swap back. There is no penalty beyond losing access to the passives themselves.

Every Class Mastery Passive, Broken Down Fast

Dragonknight: More Damage, More Sustain, More Tanking

DK gets five options, and the most impactful for damage builds is Wildfire Embers. When any DK damage-over-time effect expires, it stamps Wildfire Embers on the target, stacking up to 12 times with a 25% damage increase per stack. One confirmed bug to know: Wildfire Embers does not currently benefit from off-character-sheet Weapon Damage sources like Bloodthirsty or Wrathful Strikes, so optimized PvP and trial builds will want to wait for a fix before building around it.

Inexorable Descent boosts Landslide to add a multiplicative 1% damage, healing, and shield strength per stack on top of the additive bonus you already receive, which is a genuine power increase for sustained fights. Lead from the Front is the group-play pick: activating rank 2 of The Storm Voice grants Major Berserk and Major Protection to everyone within 28 meters for 1 second per 15 Ultimate spent.

Templar: Sacred Ground Becomes Your Core Mechanic

Every Templar mastery feeds off Sacred Ground being active, so pure Templar builds now have a strong reason to keep that ground up in all content. Bastion of Light lets Sacred Ground proc during Nova, Spear Shards, Radial Sweep, and Solar Barrage, removing the previous positioning restriction, and heals you each second it is active. At full health in combat, it generates 2 Ultimate per second. Devout Guardian layers a damage shield on top of that, absorbing up to 4,765 damage and restoring 300 of each resource while it holds. If the shield breaks, you gain 10 Ultimate.

For PvP and solo content, Steadfast Candescence gives Bracing players Sacred Ground activation and a 20% increased block amount while stationary, which pairs well with tank-style PvP builds.

Sorcerer: Pets Complicate Static Reverberation

Static Reverberation is the flashy one: your attacks have a 5% base chance to trigger a bonus Shock hit every 300ms, and that chance scales up by 1% for every 1% of the target’s missing health. The catch is that each permanent pet active on your bar divides the trigger chance. Pet Sorcerers lose out significantly here, so this mastery is designed for non-pet damage builds.

Calculated Defense rewards cast-time ability users with a 0.5-second shield absorbing 30% of your Max Health. If the shield survives, you and nearby group members gain 6% Weapon and Spell Damage for 20 seconds. That is a meaningful group buff on a mechanic that good players can reliably proc.

Nightblade: Above and Beyond Is the One to Watch

Nightblade’s Above and Beyond increases Critical Damage and Healing done by 25% (reduced to 5% against players) and raises the Critical Damage and Healing cap by 30%. For PvE trial builds chasing parse numbers, that cap increase alone changes the ceiling on what NB damage can reach.

An Eye for Exploitation scales Weapon and Spell Damage up to 2,000 based on your target’s missing health and cuts your own damage taken by up to 20% based on your attacker’s missing health. In solo content and overworld play, this passive becomes stronger the longer a fight drags on.

Share the Spoils upgrades rank 2 of Transfer to double Ultimate gain to 4 and grant all group members 250 Magicka, 250 Stamina, and 2 Ultimate on activation. Group NB just got a noticeable utility bump.

Necromancer: The Tooltip for Cycle Unending Is Wrong

Before anything else: the in-game tooltip for Cycle Unending overstates the damage bonus significantly. The tooltip reads 1% damage potency per 1% health advantage over your target, capped at 25%. What actually happens on live is that the scaling is one quarter of the health percent gap. At full health against a 75% health target, you get roughly 6.25% damage, not 25%. Expect this to be corrected or clarified after launch.

Nothing Wasted is the build-warping one. Every time you consume a corpse (with no cooldown), you gain a stack increasing Max Health and Weapon and Spell Damage by 2% each, up to 10 stacks. Stacks decay three at a time rather than all at once, so uptime is manageable.

Warden: Status Effects Are Now a Core Damage Layer

Tundra’s Maw applies Major Brittle for 2 seconds whenever you Chill an enemy, increasing Critical Damage taken by 20%. For any Warden using Winter’s Embrace abilities alongside group members running Critical Damage builds, this is a direct group DPS increase with zero extra button presses.

Wild Adaptation grants 333 Weapon and Spell Damage per status effect active on your target, up to 1,665 at five stacks. A Warden stacking multiple status effects through frost, poison, and nature abilities can self-sustain a near-permanent damage buff in longer fights.

Arcanist: Abyssal Emergence Makes Ultimate Rotations Pop

Abyssal Emergence gives Arcanist players maximum Crux instantly on activating any Ultimate, plus 666 Weapon and Spell Damage for 15 seconds. For builds that rely on Crux-based damage amplifiers, this means your first ability after an Ultimate cast hits at near-peak power every time.

Unbound Potential upgrades Fated Fortune to add 30% damage done for the duration (15% against players), which is one of the largest single-passive damage bonuses in the new system. Erudite’s Rigor adds Minor Cowardice to attackers and Major Vitality to your group while also generating 1 Ultimate per Crux held, making it the top choice for support-leaning Arcanist builds.

Class Ability Changes: Who Got Nerfed and Who Got Buffed

Dragonknight Gets Restructured, Not Gutted

The two key DK offensive passives that rewarded specific rotations have both been removed. Flame Lash no longer grants increased damage done after consuming all charges, and Molten Whip no longer stacks damage done per stack. ZeniMax moved those bonuses into the Class Mastery system, so pure-class DK players get the damage back through Wildfire Embers and other masteries. Subclassing DK players lose those passive boosts permanently.

Heart of Flame now heals 15% of Max Health per tick instead of scaling off missing health, making the heal more consistent but less explosive when low. Engulfing Dragonfire can now apply Wildfire Embers to the first enemy hit up to once every 4 seconds, giving DK a way to stack the mastery effect without relying solely on the DoT expiration mechanic.

The Inferno and Incinerate bug fix is worth noting: their damage is now correctly flagged as direct damage in all cases, which affects how certain buffs and sets interact with those abilities.

Nightblade Takes Two Meaningful Hits

Born from Shadow (Shadow Cloak passive) drops from a 10% multiplicative bonus to a 15% additive bonus. In nearly every real-game build, multiplicative 10% beats additive 15% once you stack damage modifiers, so this is a clear nerf for geared NB players.

Pressure Points now grants 2% Critical Chance per Nightblade ability slotted rather than 2.5% per Assassination ability slotted. Builds running heavy Assassination skill bar setups will see a net reduction in Critical Chance from this passive alone.

Warden Gets a Genuine Buff to Northern Storm

Northern Storm now grants 4% damage done per stack, up from 2%, but drops to 1% per stack while Battle Spirit is active. For PvE content, this doubles the upside of one of Warden’s core damage passives.

Nature’s Gift has been updated to restore 125 Magicka and 125 Stamina when healing any target with a Green Balance ability, with rank 2 doubling that to 250 each. Warden healers and hybrid builds both benefit from improved resource return.

Arcanist: Languid Eye Nerf Targets One Specific Abuse Case

The Languid Eye maximum stack count has been reduced and stack generation now has a cooldown. If you were using this ability in a normal rotation, the change has almost no effect. The nerf is targeted at the interaction with Crypt Cannon’s Vestments, where players could cast Languid, generate Ultimate from the set, cast Languid again, and let ramp-up damage compound past the intended limit.

Empower Just Changed and It Affects Almost Every Heavy Attack Build

Empower shifts from a 70% multiplicative Heavy Attack bonus to a 150% additive bonus, and it is disabled while Battle Spirit is active. Whether this is a buff or roughly even depends entirely on how many other additive damage bonuses your build stacks. Lightly buffed builds may see a gain. Highly optimized builds with many additive modifiers will likely see the math come out close to even or slightly down. Testing on your specific setup before assuming it is a buff is worth the time.

Item Set Reworks: Multiplicative Bonuses Are Going Additive

ZeniMax converted several top-tier sets from multiplicative to additive damage, then buffed the numeric values to compensate. Here is what changed:

Unsoul: Interrupt bonus increased from 7% to 14%, duration extended from 10 to 30 seconds, now additive

Bahsei’s Mania: Buffed from 10% to 15%, now additive

Tiber Wolfstalker: Buffed from 12% to 15%, now additive

Aerie’s Cry: Now buffs all damage done by 10%, not just Animal Companion abilities

Eternal Lancer (Aetheric Lancer): The damage proc is now classified as a class ability (buffed by sources like Solar Barrage), the Weapon and Spell Damage buff lasts 10 seconds instead of 6, and the cooldown was quietly changed from 6 seconds to 3 seconds in a late patch note update that was not included in the main notes. That cooldown change is significant for any build using this set.

Monolith of Storms

 Deals more damage and now grants 100 Weapon and Spell Damage for every active Monolith. The patch notes state 37.5% more damage, but PTS testing from content creators found the actual increase to be closer to 9% based on scaling coefficient changes.

Soulcleaver: 3-piece bonus changes from Max Magicka to Critical Chance. The 5-piece now reduces Siphoning ability costs by 15% (down from 21%) and draining Ultimate adds up to 12% damage done based on current health for 20 seconds.

Pyrebrand: Completely redesigned around the DK Wildfire Embers class mastery. Damage now scales with Wildfire Embers stacks on the target, Heavy Attacks consume Wildfire Embers stacks instead of generic DoT effects, and the set applies Wildfire Embers directly once every 10 seconds. This is now a DK-specific set in all practical terms.

Rattlebone (now Wrathsun): Stack cap reduced from 40 to 30, Magicka Recovery per stack increased from 12 to 21, and at max stacks you now get 25% increased damage done with Templar skill line abilities (10% in PvP) rather than a Dawn’s Wrath scaling bonus.

Savage Werewolf: 2-piece changes from Max Stamina to Critical Chance, 4-piece changes from Stamina Recovery to Weapon and Spell Damage, and the set now adds 6% damage done while in Werewolf form.

Beacon of Oblivion: PvP-only change. The Battle Spirit bonus increases to 7%, up from 5%.

Werewolf Overhaul: The Transformation Finally Works Like a Real Form

The Werewolf transformation has been rebuilt from the ground up. The biggest structural changes:

The form now costs 100 Ultimate to activate and drains 100 Ultimate every 10 seconds while active. Ultimate generation is no longer disabled in Werewolf form, making it the primary way you sustain the transformation in combat. The out-of-combat drain is also removed, so you are not forced to fight constantly just to stay transformed.

A new resource called Fury has been added to the Werewolf bar. You build Fury (up to 1,000) by activating Werewolf abilities in combat. At 1,000 Fury, the Ultimate slot converts to Rampage: spend all your Fury to enter a 20-second window with 15% increased damage done, 20% increased Movement Speed, and zero Werewolf ability costs.

Pounce now dynamically switches to Carnage based on range. Pounce fires when you are more than 7 meters from your target, Carnage takes over at 7 meters and closer. The Stamina cost for Pounce dropped from 4,016 to 942.

Werewolf Stamina-costing abilities now cost one-third of the equivalent non-Werewolf category ability cost, replacing the old system where Werewolf abilities cost 25% more than normal. The previous 30% Max Stamina bonus from transformation has been removed and folded into the ability scaling directly, keeping Stamina builds competitive while opening the door for Magicka-oriented Werewolf play.

A dedicated Werewolf patch notes breakdown is coming separately given the depth of those changes.
