Mine & Forge

Depths, ores, refinery, gear

This table shows the seven depths of the Mine, from the Surface Tunnels down to the Crystal Caverns. Read it from top to bottom, since you open each depth by gaining Mine Mastery from your runs. Base time is the length of a run before your team’s Power, gear and Mastery change it, and stamina cost is what each explorer pays (or one Pickaxe instead). Recommended Power is the team strength the depth expects; going under it makes runs slower and rare finds less likely. The main ores always arrive, while each rarer extra rolls on its own with the chance shown; open a depth to see how a bigger team lifts it. Use the table to plan which ores you need next for the Refinery, then see the Mine, Refinery & Blacksmith guide.

Every run brings the guaranteed finds; each rare find rolls on its own with the chance shown (one explorer at full Power). Pick your team and gear above the table to see your own run. Open a depth for team examples.

Forge and Anvil chances

6

Every forged piece rolls its quality once. At the Anvil, 3 pieces of one quality try to fuse into the next; a failed try keeps all pieces and only costs the fee and the time. Every try is a fresh roll.
