Furnace Golems are large, powerful creatures made of living metal. They are immune to fire and resistant to most other forms of attack. To kill a Furnace Golem, you must first destroy its core. The core is located in the center of the Golem’s body and is protected by a thick layer of metal.
There are several ways to destroy the core. One way is to use a pickaxe or other tool to break through the metal layer and then attack the core directly. Another way is to use a ranged weapon to shoot at the core through the cracks in the metal layer. Finally, you can use a spell or ability that can damage the core directly.
