⚠️ Eco v0.14 is coming — the next major update reworks upgrade modules, so some of these numbers will change. They reflect the current version. What’s changing →
  • Simpler tiers: the 1–4 tiered upgrades become a single Basic / Advanced / Modern upgrade each.
  • Permanent upgrades: a module placed in a workstation is permanent — no more swapping lower tiers out as you progress.
  • Power transitions: a module can change a station’s power type/draw (e.g. a Modern upgrade moves a sawmill from mechanical to electrical power).
  • Talent-integrated: modules now use the same bonus/talent system — any talent benefit (power, labor cost, recipe unlocks) can come from a module.
  • Cheaper to upgrade: with the multi-tier parts gone, fully upgrading a workstation costs significantly less.

We’ll update this calculator shortly after the update releases.

Notes

The Bloomery is a placed, tier-2 furnace for smelting ores like iron, copper, and gold, and for crafting metal items such as anvils, cast iron furniture, and town bells. It requires an enclosed room with at least 28 m³ free volume using tier-2 building materials (e.g., bricks), and burns burnable fuel at 10 J/s to operate. A practical tip: before placing your Bloomery, upgrade your room to tier-2 and stock fuel, then consider installing a Smelting Basic Upgrade module to reduce craft time and resource costs.
