Furnace III

Furnace III is the highest-tier smelting station in Starsand Island, capable of processing the rarest and most heat-resistant ores in the game into premium-grade metal bars. An endgame facility that completes the full metallurgical production chain, Furnace III enables the production of the advanced materials required for Worktable III crafting and the most powerful tools and vehicles available.

Building Furnace III marks the completion of the smelting upgrade path and unlocks the ability to process rare endgame ores that fuel the island's top-tier crafting recipes. Combined with Worktable III, it forms the core of a fully upgraded endgame production facility. Players focused on reaching the game's crafting ceiling should prioritize building Furnace III as part of their final production setup.
