Furnace Upgrades
Upgrade your furnaces to dramatically boost smelting speed and fuel efficiency — get more from every ore.

What are Furnace Upgrades?
Furnace Upgrades are permanent improvements you can apply to large and small furnaces. Once upgraded, your smelting process becomes faster, more efficient, and produces better output per resource.

How does it work?
Upgrade your furnace via the in-game menu using resources or progression points. Upgrades stack across tiers and persist until the furnace is removed.
