ESO Update 50: Best Infinite Archive Sets to Farm

Update 50 rewired how ESO class sets work. Most of them were mediocre for years. That changes now: but only if you know what to farm and why.

The Infinite Archive is a free endless dungeon in Apocrypha, available to all players regardless of DLC ownership. Two trash stages plus a miniboss equal one cycle. Five cycles equal one arc. At arc's end, you get class-specific gear. Historically, you had better things to do. ESO Update 50 changes that math.

Update 50 introduced Class Mastery passives: powerful effects unlocked when you hit level 50 in your native class skill lines and avoid subclassing. Several Infinite Archive sets were explicitly redesigned around these passives. The result: combinations that border on absurd in PvE. A guide was needed. Here it is.

The 7 Sets: One Per Class

Meta Corpse Burster Synergy: Malevolent Promise

Consuming a corpse explodes it, dealing magic damage and applying Minor Breach. With the new Malevolent Promise passive, corpse consumption marks enemies with Death's Touch, allowing you to chain corpse-consuming abilities endlessly. It cannot be countered in PvP: because it's disabled there. In PvE, it's explosion city with no ceiling. Farm this first if you have a Necromancer. The synergy between ESO class mastery passives and corpse mechanics here is the most complete in the update.

Redesigned Pyrebrand Synergy: Wildfire Embers

Previously capped at 60% bonus damage from generic DoT effects. Now scales off Wildfire Embers stacks: up to 300% bonus at 12 stacks. Wildfire Embers applies a 12-second Flame damage DoT every time a DK DoT expires, stacking 12 times at +25% damage per stack. Dragonfire Breath feeds it relentlessly. Heavy Attacks now consume Wildfire Embers stacks instead of generic DoTs. Pyrebrand also applies Wildfire Embers directly once every 10 seconds. This set is DK-exclusive in every meaningful way now. It is the backbone of any competitive Dragonknight DPS build Update 50.

Buffed Monolith of Storms Synergy: Static Reverberation

Storm Calling abilities create Monoliths next to enemies: up to three, linking together to deal Shock damage. The set now hits ~37.5% harder and grants 200 Weapon and Spell Damage per active Monolith, meaning 600 total at max. Static Reverberation: a reworked version of the old Implosion passive: adds a scaling Shock damage proc based on target's missing health. The combo snowballs hard on low-health targets. Note: each permanent pet on your bar divides Static Reverberation's trigger chance. Run petless or accept the penalty. Best Sorcerer build ESO in the current meta leans on this combination.

Adjusted Aerie's Cry Synergy: Tundra's Maw

Previously, this set only boosted Animal Companion skill damage by 10%. Now it applies to all Warden damage. Simple. The new Tundra's Maw passive enables a frost-focused Warden to benefit fully without running any Animal Companion abilities. The Warden class rework was delayed to U51, so this change is deliberately restrained. Expect this slot to get considerably more interesting next patch.

Major Buff Spattering Disjunction General: no single passive

Now increases status effect damage by 40% and generates a Crux on activation. The Arcanist already focuses heavily on status effects: Abyssal Ink being the signature. No direct Class Mastery pairing here, but the set became a cornerstone of any Arcanist PvE build through sheer numbers. Farming this is a straightforward decision if you play one.

Buffed Wrathsun Synergy: Judgment's Brand

Easier to reach max stacks, more Magicka Recovery, and increased damage across all Templar skills. At max stacks, Templar abilities hit 25% harder (10% in PvP) and fire a Wrathful Nova. Pairs with Judgment's Brand class mastery. Aetheric Lancer also got buffs: it's now considered a class ability, and its Weapon/Spell Damage buff persists 10 seconds instead of 6: but Wrathsun is the better farming target for most. This is the best Templar set ESO U50 for damage output.

Reworked Soulcleaver Synergy: Above and Beyond

The 3-piece bonus now grants Critical Chance instead of Max Magicka. The 5-piece buffs Siphoning ability damage and healing, reduces their cost by 15%, and draining Ultimate can push your damage by up to 12% based on current health. The Class Mastery synergy is looser here than for other classes, but the extra crit feeds Above and Beyond well enough. Siphoning builds get a genuine quality-of-life improvement from the cost reduction alone.

How Class Mastery Works

Class Mastery passives unlock once you've reached level 50 in your native class skill lines. The catch: no subclassing. If you've mixed in another class's skills, you forfeit these passives. This is a deliberate design push toward pure-class builds: which is exactly why the Infinite Archive sets were redesigned around them.

These passives are passive in name only. Wildfire Embers stacks 12 times and scales damage by 25% per stack. Static Reverberation fires a bonus Shock hit with increasing frequency as targets lose health. Malevolent Promise converts corpse consumption into a perpetual damage loop. The ESO Class Mastery system is not a small power gain. It is a character rebuild decision.

Core Rules

• Play the class whose set you want. The Archive drops gear for whichever class you're on.
• Run Arc 1 and Arc 2 only, then repeat. Odd arcs drop armor. Even arcs drop jewelry and weapons. The dungeon gets significantly harder after Arc 2: there's no reason to push further when farming.
• When buying from the vendor Filer Brax, select the curated options. They cost more Archival Fortunes, but guarantee a piece you don't already own.
• Solo run? Bring a tank companion. They hold aggro while you delete things.
• Group runs are faster. Use Activity Finder or recruit in zone chat. Someone will show up.

Farming the Infinite Archive solo ESO is completely viable, but the companion makes a real difference on harder cycles. For group runs, the dungeon scales, so bringing three DPS and a tank companion each isn't optimal: coordinate before you go in.

What to Do Right Now

1. Decide which class you're maining in U50.
2. Confirm that class hit level 50 in all native skill lines (Class Mastery requirement).
3. Log that character into the Infinite Archive.
4. Run Arcs 1 and 2. Repeat until you have a full set.
5. Do not get distracted by Arc 3. It is not for you right now.

The best ESO sets to farm Update 50 are all inside one free dungeon. There is no excuse not to start.
