Disable Wither blue skull attacks

Understanding blue skulls

When a Wither enters its invulnerability phase (after taking enough damage), it fires blue skulls that explode and destroy blocks indiscriminately. These are destructive and hard to predict, making farms unreliable.

How to turn them off

Using commands:

• Type /gamerule wither_cage_fix:allowBlueWitherSkulls false in chat
• The gamerule is false by default, so blue skulls are already disabled unless you've changed it

Checking the current setting:

• Use /gamerule wither_cage_fix:allowBlueWitherSkulls to see the current value
• false = blue skulls disabled (safe)
• true = blue skulls enabled (destructive)

Why disable them

With blue skulls off, the Wither only shoots black skulls at its target, making its behavior predictable. Your farm arena only takes damage where you expect it, and you can design containment more reliably.
