"An incredibly powerful upgrader that requires ore be directly dropped into it."
The Ore Steamer is an Uncommon-tier upgrader that requires ore be inserted using a Large Conveyor Ramp or similar. Its upgrade multiplier is similar to the Industrial Ore Welder, starting with a 6x multiplier (If upgraded it does 2x, which is the same as the Industrial Ore Welder), then ending with a lower upgrade of 1.6x. The Ore Steamer does not count as an upgrade, and thus is able to upgrade ores while still allowing them to be used with cell furnaces.
- The Large Conveyor Ramp does not exactly align with the insertion hole as its hitbox is 4x4. Using a Centering Conveyor will make it line up exactly.
