Delves and souls
Pressure-Locked Delve Cache exchange
Use Pressure-Locked Delve Caches to address a specific shortage of Delve materials.
WHERE & HOW TO FARM
Pressure-Locked Delve Cache exchange
Heavy Pressurized Chests encountered in Delves; exchange caches with the Geodian merchant.
Before you go
- Delve access and a build able to complete floors containing heavy chests.
- Inventory room for caches and materials.
- A specific Delve crafting or module target.
- Access to the Geodian merchant for the exchange.
Farming steps
- Identify the Delve material needed for a particular module or crafting target.
- Enter Delves and complete floor objectives while watching for Heavy Pressurized Chests.
- Open eligible heavy chests and collect any Pressure-Locked Delve Caches they provide.
- Continue normal progression only while the depth remains manageable.
- Visit the Geodian merchant and inspect the available cache exchange options.
- Trade caches for the material that directly fills your shortage.
- Use the material on the planned module or craft and verify the target is funded.
- Repeat chest collection and exchange only if that same target still needs resources.
- Choose the exchange after identifying the recipe or module, since the useful material depends on your current shortage.
- Heavy chests and Shadowy Soul Vaults are different targets with different reward rules.
Repeat, collect and use
Repeatable collection and exchange when caches are obtained; the cache source is not a guaranteed drop from every heavy chest.
Common mistakes
- Opening vaults for cache rewards: look for Heavy Pressurized Chests for this route.
- Exchanging before choosing a target: match the trade to a specific material shortage.
- Assuming every heavy chest yields a cache: continue Delve progression and treat cache drops as variable.
When to stop or switch
Stop when the desired module or crafting target is funded; switch to the actual Delve activity or another material source instead of stockpiling unnecessary exchanges.
