Changes

1.21.11 requires changes that need a new version entirely which is ready for release, I'm just waiting for full release.

DIRECT CHANGES TO THE WITHER

• During the First Phase (300HP-600HP) the Wither will move away from players to maintain its distance and have more effective attacks.
• Skulls shot by the Wither have been buffed further as dangerous (blue) skulls will now have a bigger explosion doing quite a bit more damage than before leaving smoke behind.
• Wither now has less armour during the first phase and increased armour during the second phase.
• Converted Skeletons now carry bows since the mobs they convert from have bows.
• Changes to the amount of Blazes spawned during midpoint
  • <5 Players = 10 Blazes
  • <10 Players = 20 Blazes
  • >10 Players = 30 Blazes

CHANGES TO ATTACKS

• A swarm of smaller wither skeletons will spawn at 150HP helping the Wither deal with close range attackers.
• The Wither will now regularly shoot a burst of skulls directly at the nearest player, additionally, the skull it shot at the player in earlier versions will now be a slow fire shot marked as dangerous

Fixes

• Fixed Wither destroying bedrock in very specific cases
• Reduced volume on enraged skulls they were incredibly loud at 100%

Enjoy! 😎
