Furnace II

Furnace II is the mid-tier smelting station in Starsand Island, upgraded from Furnace I to handle a broader range of ore types and produce higher-quality metal bars. As players encounter mid-game mineral deposits that cannot be processed by the basic furnace, Furnace II becomes an essential upgrade. It enables the production of the refined metals required for bronze-tier and advanced crafting recipes.

Building Furnace II unlocks the ability to smelt mid-game ores into the metal bars needed for Worktable II-tier tools and equipment. It is a critical component of the mid-game production chain, bridging the gap between early-game iron tools and the high-performance metals used in endgame crafting. Upgrade to Furnace II as soon as you begin encountering ore deposits that Furnace I cannot process.
