Ore and mining routes
Glassrock in Fields of Mourning
Glassrock is a region-specific ore that can satisfy a focused progression or upgrade requirement.
WHERE & HOW TO FARM
Glassrock in Fields of Mourning
Ore deposits in the Fields of Mourning on the Underworld route; mine them with the Crescent Pick.
Before you go
- 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.
Farming steps
- 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.
- 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.
