Orthen furnace core detail.png

The Orthen furnace core is a skilling off-hand which requires level 99 Smithing and level 102 Archaeology to create. It provides benefits to the Firemaking and Smithing skills while equipped.

Boosts can be used to meet both the Archaeology and Smithing requirements, but the requirements to make the untradeable masterwork ingredients cannot be assisted.

Currently, it is not augmentable, though augmented versions of the Orthen furnace core exist within the cache.

If lost in the Wilderness, the Orthen furnace core will not drop for the killer, and can be re-obtained by the owner if collected within 2 minutes. It will otherwise be lost.

Effects[edit | edit source]

  • The Superheat Form curse does not use prayer points.
    • Note: Superheat Form can only be activated with 1 or more Prayer points, even with the Orthen furnace core equipped.
  • The player can remove the sticky fungus from Croesus without the need for logs in the inventory.

Firemaking[edit | edit source]

Smithing[edit | edit source]

  • If the Breakdown perk activates, the player gains the Furnace Core buff: It provides a 5% increase to Firemaking and Smithing experience, lasts for 5 minutes, and can be refreshed up to 5 minutes by triggering either of the perks again.
  • The scroll of efficiency effect has a 25% increased chance to occur (from 2% to 2.5% chance for bars to be refunded upon finishing a smithing project).
  • Smithing can also spawn a forge phoenix.
