"An amazing machine that removes all status effects such as Radioactive and Flaming from an ore and removes all tags, allowing it to go through limiting machines again. Can only be used once."


The Tesla Resetter is a Reborn-tier upgarder. It does not upgrade ore, but removes all effects and tags from ores. This allows ore to go through the same upgraders all over again making ores even more valuable.

The Tesla Resetter can only be used once (you can not use a second Tesla Resetter to remove the tag effect of using the first Tesla Resetter). You are able to get this starting at your 5th life (Genesis).


  • Tesla Resetter name comes from Nikola Tesla, known for inventing alternating current and the Tesla coil, two of which are present on the machine.
  • The Tesla Resetter's hitbox used to be broken, requiring a Conveyor Ramp to reach Tesla Resetter. This has since been fixed.
  • Although, Tesla Resetter removes all tags and effects, ores upgraded then passed through the Tesla cannot be processed by a Cell Furnace (It doesn't change the fact that the ore has been upgraded in the past).
  • The tags and status the Tesla Resetter removes include fire, radioactivity, azure flame, sparkles, decals, meshes, upgrades, and the Ore Tracker's tag.
  • The Tesla Resetter will remove the Ore Illuminator's upgrading tag rather than destroy the ore
  • The Tesla Resetter is tied with the Ore Magnifier for the sixth largest upgrader. The Final Eclipse Gate is currently known to be the largest upgrader in the game.
  • This upgrader is heavily used in end-game setups or loops, as its effects allow ores to be upgraded much more.
  • The only other upgraders able to perform this effect are The Ultimate Sacrifice, The Final Upgrader, and the Tesla Refuter. The Tesla Resetter cannot reset the status of being upgraded by the Ultimate sacrifice or the Final Upgrader, however and vice versa.
  • The Ore Negator and Vulcan's Grasp are unaffected by this items resetting effect, meaning they can only ever be used once.
