Chisel is a tool that can be found in Monster Loot or Chest loot as a very rare item, used to upgrade machines. It also allows player to open Stardust Crystals obtained from the Stardust Crystal Potion effect.
Each use to carve gems using 5 gems will give the 10 machines of the matching tier a one time-permanent upgrade, regardless of whether all 10 machines have been crafted.
