ESO Update 51 Nowhere Vault Guide: How to Farm Keys, Unlock Wings & Get Rewards

Summary

The Nowhere Vault is one of the most exciting additions in ESO's Update 51, arriving September 28, 2026. It blends puzzle-solving, stealth, traversal, and randomized rooms into a unique PvE experience. This guide covers how to enter, farm keys, how the vault works, every reward, and the best key farming routes — or you can just buy ESO Items to skip the grind.

What Is the Nowhere Vault?

The Nowhere Vault exists in a space outside of Nirn, not quite a plane of Sage Voernet's own choosing. It was created not only to house rare treasures and artifacts, but to test adventurers deemed worthy of its challenges.

The official description calls it a "mystifying new PvE experience" for solo or group play. It contains three unlockable Wings, each made up of randomized rooms. Challenges include mazes, traps, stealth, traversal, and light combat.

From PTS gameplay footage, the majority of the content focuses on mobility, stealth, and awareness rather than pure combat. Think of it as "Infinite Archive meets key-gated puzzle rooms."

How to Enter

Two requirements:

1. A Wondrous Nowhere Key. This is the hard gate. Without a key, you cannot enter.

2. Complete or skip the prerequisite quest. If you've finished the new Thieves Guild questline, you can jump straight in. If not, you can grab the introductory quest "Invitation to Treasures" from the Crown Store for free.

Nowhere Key Farming — Every Source Explained

This is the most contentious part of the system. Community complaints about key drop rates have been widespread. But with Update 51, several sources have had their rates increased.

1. Favor System (Most Reliable)

The only guaranteed and repeatable key source.

How it works: Complete the 10th and 20th quest on any Favor Board to earn 1 key each. That's 2 keys per board, 6 keys per character across all three boards.

Important: This is per character, not per account. Swap characters to keep earning.

Bug warning: Lady Arabella's 20th Favor in Glenumbra is currently bugged and cannot be completed. So a single character caps at 5 keys.

Tracking: Press J → Lore Library (book icon) → scroll to Correspondence to see Favor counts per board.

2. Dynamic Encounters (Best Current Farm)

Dynamic Encounters are the most recommended key farming method right now.

Best spot: The vampire hunt in Glenumbra. The objective is simply "kill vampires" — no puzzles, no fire-extinguishing, no fishing. With multiple players farming it, completions are fast.

Tracking: The dynamic encounter icon moves around the zone depending on which stage it's at. If you can't find it, check where the current stage is.

3. Treasure Chests & Treasure Maps

Chests and treasure maps are reliable sources. Players report roughly one key per day from treasure map chests.

If you have a backlog of treasure maps, open them now. If not, waiting until after Update 51 for boosted rates is also fine.

4. Thieves Guild Heists

Heists are considered one of the better drop sources, with consistent community reports of keys dropping.

5. Other Sources (Rates Increased in Update 51)

Delve Bosses

World Bosses

Solo Dungeons

Rumors

All of these have had their key drop rates increased with Update 51.

How the Vault Works

Key Costs at a Glance

Group advantage: In a group, key usage is shared. If you open a chest with a key, all four players can loot it. This dramatically reduces the per-person key burden.

Room Types

Challenge Rooms — Core challenges: puzzles, traps, stealth, combat

Story Rooms — Story progression

Jackpot Rooms — Treasure rooms packed with chests and resource nodes. The biggest payoff per run.

Nowhere Chests — Hidden chests requiring extra keys

Maps & Route Planning

You can find maps inside the vault that let you fast-travel to specific rooms. Once you learn the layout, you can plan your route instead of relying on randomization.

The Three Wings

Arcanum Wing

Lunar Path Wing

Cursed Castle Wing

Completing each Wing's secret objectives earns a Wing Seal. Collect all three and break the final barrier to unlock the Ancient Direnni Quasigriff mount.

All Rewards

On trial sets: Some community members argue that dropping trial sets devalues trial content. In reality, you get base versions, not Perfected trial gear. For solo players without a dedicated trial group, this is a significant gear acquisition path.

Efficient Farming Tips

If you want to start stockpiling keys now:

Farm Glenumbra dynamic encounters (vampire hunt) — fastest, least brainpower required

Open treasure maps and chests — clear your backlog now

Do Favor quests — especially the first 10. This is the guaranteed key source

If you have multiple characters:

Each character can independently complete Favors for keys. One character doing the first 10 Favors on all three boards earns 3 keys. Stack across characters for a serious reserve.

Group up for the Vault:

Grouping gives you shared key usage, and harder challenge rooms are easier with coordination. But your teammates also need keys for the shared mechanic to pay off.

Key Reminders

The official key name is "Unformed Planar Key", not "Nowhere Key." Search that name if you can't find them in your inventory

Lady Arabella's 20th Favor in Glenumbra is bugged, capping a single character at 5 keys

Nowhere Vault is free Season One content — no purchase required

Launches September 28, 2026 with Update 51

Bottom Line

The Nowhere Vault is essentially "Infinite Archive plus key-gated puzzle rooms plus treasure rooms." The core appeal is exploration and discovery, not pure combat. The biggest barrier is keys, and the most efficient key farm right now is the Glenumbra dynamic encounter. Grouping shares key costs, improving everyone's return on investment.

If you enjoy the randomness of the Infinite Archive but want more puzzle-solving and exploration, the Nowhere Vault is built for you. If you'd rather skip the farming and gear up faster, MMOEXP is a trusted source for ESO Items for sale, with secure delivery and competitive pricing.
