Glassrock is a region-specific ore that can satisfy a focused progression or upgrade requirement.
PC / Global release, version 1.0
WHERE & HOW TO FARM
Where to farm
Ore deposits in the Fields of Mourning on the Underworld route; mine them with the Crescent Pick.
Glassrock is mined in the Fields of Mourning, reached by advancing along the Underworld route through Erebus and Oceanus. Unlock the Crescent Pick before the run; gathering tools are then active automatically, with no manual loadout step. Treat the Fields as a series of chamber checks rather than assuming a deposit appears in a particular room. Mine any visible Glassrock before taking an exit, and confirm at the Crossroads that it remains the resource your next recipe or upgrade needs. The ore you collect should go directly toward that selected requirement.
Unlock the Crescent Pick in the Crossroads gathering tools.
Unlock the Underworld route and progress to the Fields of Mourning.
Check the Cauldron or upgrade menu to confirm a Glassrock target.
Choose an Underworld run and advance through Erebus and Oceanus to the Fields.
At each chamber, scan its reachable edges and paths for an ore deposit.
Clear nearby threats if they block access to a visible vein.
Interact with each Glassrock deposit to mine it with the Crescent Pick.
Before leaving, check the chamber once more for other visible ore deposits.
Continue across the Fields, repeating the room scan as you advance.
At the Crossroads, use the Glassrock for the recipe or upgrade that motivated the run.
Farming tips
The route identifies where to look, not a guaranteed deposit in each chamber.
If Bronze or Iron becomes the bottleneck, change to the Surface route rather than extending this search.
Repeat, collect and use
Repeat Underworld runs when a displayed requirement still calls for Glassrock. Deposits are variable room finds, so gather what appears and do not count on a fixed haul. Spend the ore on the planned Crossroads requirement and reassess before another targeted run.
Common mistakes
Taking the Surface route for Glassrock: progress through the Underworld to reach the Fields.
Leaving immediately after combat: scan the chamber for deposits before exiting.
Assuming the Crescent Pick needs to be equipped for the run: unlock it and the tools activate automatically.
When to stop or switch
Stop prioritizing Glassrock when the planned amount is collected or another resource becomes the current bottleneck.
