The Wither Assembler automatically builds and spawns a Wither once it has the required materials, enough power, and time to finish the assembly cycle. It is a dangerous late-game automation block and should only be used in controlled areas.

• Connect the machine to a powered Energy and Electricity network.
• Insert 3 Wither Skeleton Skulls into the skull slot.
• Insert 4 Soul Sand into the body slot.
• Make absolutely sure the spawn area is secured before letting the cycle finish.

• The machine consumes 4096 J for each Wither it assembles.
• It stores up to 4096 J.
• Each assembly cycle has a 30-second cooldown.
• When the cycle completes successfully, the machine spawns a real Wither entity in the world.

• Build strong containment before using this machine anywhere near a base.
• Check server rules and protection setups first, because automated Wither spawning is not a casual utility block.
