WHERE & HOW TO FARM
Corestone at Icehelm for Tier 3 Machinery
Icehelm’s underground claim behind the sign opposite the entry doors; its small water pool sits beside the wide surface input conveyor, while the mine extends horizontally into the wall.
Before you go
- Access to Icehelm and its mining claim; the starter Ember Cradle does not provide automated Corestone from Tier 1 dirt.
- Tier 2 or Tier 3 drill and a harvester of compatible tier for the dirt being mined.
- Water supply, pipes, and room to smelt and mold Corestone bars.
Farming steps
- Enter Icehelm and find the mining-claim sign behind the central structure, opposite the doorways; the claim runs into the wall rather than straight down.
- Locate the small pool beside the wide conveyor that carries items to the surface; use this as the claim’s water source.
- Treat the front of the claim as Tier 1 and plan the tunnel farther into the wall before installing a Corestone line.
- Advance into higher-tier soil with equipment capable of working the tier you are entering, keeping the access route wide enough to service the drill.
- Confirm that the drill is positioned in Tier 2 or Tier 3 dirt and is compatible with that tier before connecting the harvester.
- Connect and test the water supply, then run a small batch to verify the drill is feeding the harvester and material is being processed.
- Collect Corestone Ore from the output and keep it separate from Iron, Gold, Cloutium, and gems so the scarce upgrade material is not sold accidentally.
- Load Corestone Ore into a Crucible, melt it, and use a Casting Mold to form Corestone Bars for the planned Tier 3 machine recipe.
- Icehelm’s tier layout runs toward the back wall, not down from the entrance floor.
- Corestone is rare even in eligible dirt; do not assume a short test batch proves the setup is broken if the output has not appeared yet.
- The Corestone item entry lists the Jeweller as a sale outlet, but bars are needed for machine upgrades, so reserve material first.
Repeat, collect and use
Repeat the tier-compatible drilling and smelting loop until the current Tier 3 machine plan has enough Corestone Bars. Corestone is rare and no fixed output rate is assumed.
Common mistakes
- Running a drill in Icehelm’s front Tier 1 area while expecting automated Corestone.
- Using a drill or harvester that cannot work the soil tier where the setup is placed.
- Digging straight down at Icehelm instead of progressing horizontally into its higher-tier dirt.
- Selling raw Corestone before checking the Tier 3 machine materials needed at Icehelm.
When to stop or switch
Stop when the current Tier 3 machinery recipe is supplied or when the drill and harvester are no longer operating in their matching soil tier; correct the site before restarting.
