How to unlock Etchspace Salvage
To unlock Etchspace Salvage, reach Authority Level 25 and complete the Main Quest up to Chapter 1 - Process 3. After that, the Etchspace Salvage Quest appears as a priority mission.
Completing it takes you back to OMV Dijiang, where you meet Aquito and unlock the portal that introduces the mode mechanics. Once finished, the mode becomes permanently available.

How Etchspace Salvage works
Each run places you in an area filled with enemies, Precipitation Crystals, Storage Points, and shortcuts. While exploring, your Derangement slowly increases.
Opening Storage Points, fighting enemies, and staying too long will raise it faster. The idea is to gather what you need and extract before Derangement becomes a problem.
When you successfully extract, certain materials convert into rewards like Aurylene Crystals and Operation Metrics.
Destroy Precipitation Crystals first
Precipitation Crystals are scattered across the map. Destroying them drops Nodules. When you extract, these Nodules automatically convert into Aurylene Crystals.
Each Aurylene Crystal gives one Operation Metric. Aurylene Crystals are also used to reroll or add Focus Commissions and sometimes act as Commission turn-in requirements. If your inventory has room, farming these is one of the safest and most consistent ways to gain progress.
Use Storage Points wisely
Storage Points are tied to specific item types.
Packages drop Classified items. Instrument Safes drop Gold Statuettes. Auto-Vendors provide Specimens.
Opening them increases Derangement, so only open what your active Commissions require. If you only need Gold Statuettes, focus on Instrument Safes and ignore the rest. This keeps your run controlled and efficient.
Loot chests for Oroberyl
Chests are scattered around the map and contain Oroberyl. They are easy to grab while moving between objectives. Make it a habit to collect them during exploration since they add steady value without extra risk.
Unlock Ziplines and Ropes early
Ziplines appear as pillars of light and unlock when approached. They create shortcuts between zones or layers.
Ropes function similarly but connect different floors inside a zone.
Unlocking these early makes future runs faster and reduces unnecessary Derangement buildup. Even if you plan a short run, activating shortcuts helps long term.
Complete Exploration Commissions for permanent buffs
Exploration Commissions unlock permanent Support Tech bonuses. These upgrades make every future run easier.
You can increase Derangement Limit, reduce Derangement buildup with Derangement Tolerance, expand Isolation Container capacity, improve Nodule Refining efficiency up to 150 percent, and gain combat benefits like HP or SP recovery.
Prioritize these early. Permanent buffs give more long term value than short term farming.
Finish Key Commissions to progress
Key Commissions move the story forward and unlock new areas. Clearing all Key Commissions up to Aberrant Zone 3 unlocks Focus Commissions.
They also unlock higher rarity turn-in items, which improves later Exploration and Focus tasks. If you want access to better rewards, focus on completing these first.
Focus Commissions explained
Focus Commissions are weekly quests that reward large amounts of Operation Metrics.
You can have up to four active at the same time. Each completed Focus Commission grants 5000 Operation Metrics.
You can spend Aurylene Crystals to reroll an existing Commission or add a new one before the weekly reset. The cost increases each time you reroll or add. If a Commission requires rare items that slow you down, rerolling may be worth it.
Operation Metrics and milestone rewards
Operation Metrics fills a reward track with milestone prizes.
You earn one Metric per extracted Aurylene Crystal and 5000 per completed Focus Commission.
Milestone rewards include Oroberyl, T-Creds, Basic HH Permit, Advanced Combat Record, Protoprism, Protodisk, Protohedron, Cast Die, Heavy Cast Die, Protoset, and Advanced Cognitive Carrier.
The highest listed milestone reaches 40000 Operation Metrics. Consistent crystal farming combined with weekly Focus Commissions is the fastest way to reach it.
