Stamp Mill

WorldObject

A crushing machine that uses iron stamps to pound rocks into small pieces.

Notes

The Stamp Mill is a mid-tier crafting station that pulverizes rocks into crushed materials, producing items like Crushed Iron and Crushed Coal that are essential for advanced ore processing and material refinement. It accepts Advanced Upgrade and Mining Advanced Upgrade modules to improve its efficiency. Place one inside a tier-appropriate room to enable these upgrades and reduce the labor and resource costs of its crushing recipes.
