Slimesteel is an alloy created by combining Molten Iron, Skyslime, and Seared Stone in a smeltery, at a 1:1:1 ration, yielding two ingots. It can be used for tools, and is a 1.16.5 exclusive. It has a mining level equal to iron tools, and applies the Overslime material trait to tools. The Overslime trait allows for slime crystals to be used to add Overslime to a tool, which adds a durability buffer. Overslime can be refilled by applying slime crystals to the tool in a Tinker's Anvil or Tinker Station. Applying a Slime Crystal adds 10 Overslime, a Skyslime Crystal 40, Ichor Crystal 100, and Enderslime Crystal 200. The Overslime trait allows 200 Overslime to be applied. Slimesteel parts also have one other trait, Overcast. Overcast allows 75 more Overslime to be applied per level of Overcast.
