Collect Energy Crystals in the Underdust
Energy Crystals feed powerful equipment, Crystal Fuel, and Crystal Batteries, making them a valuable Underdust expedition…
WHERE & HOW TO FARM
Collect Energy Crystals in the Underdust
Walls, ceilings, and floors in Underdust locations.
Before you go
- Access to an Underdust location.
- Expedition life support suitable for the trip.
- Inventory room for crystals.
Farming steps
- Enter an Underdust location with enough supplies for a careful search.
- Scan the walls for small crystal clusters as you move through the site.
- Look upward along ceilings and overhead surfaces for additional formations.
- Inspect floors and corners before leaving each room or passage.
- Collect visible clusters by hand; a cutter is not required by the documented method.
- Store the crystals aboard and allocate them to equipment, fuel, or battery recipes.
- The main source is Underdust locations; above-ground caches are described as rare and associated with Colossal Creature points of interest.
- Search all three surface types before concluding a room is depleted.
Repeat, collect and use
Repeat the search in other Underdust locations when you need more. The evidence describes where clusters form, not a guaranteed respawn schedule for cleared sites.
Common mistakes
- Looking only at walls: clusters may also be on ceilings and floors.
- Bringing a cutter unnecessarily for collection: the documented clusters are gathered by hand.
- Planning around common above-ground crystals: those caches are reported as rare.
When to stop or switch
Stop when the current expedition has enough crystals for your planned advanced craft or when life-support supplies call for returning.
