About This Mod:

  • When the Wither works for players, it may leave Wither Skulls in unloaded chunks. Excessive accumulation of these skulls can cause lag, unresponsiveness, or even crashes when reloading those chunks.
  • This mod limits the existence time of Wither Skulls to 6 seconds (without affecting normal Wither battles).
  • If your world is already polluted with excessive Wither Skulls, loading this mod will remove them when loading previously saved chunks.
    • During testing:
      • ~5,000 skulls were removed instantly
      • ~30,000 skulls took about 4 minutes to remove completely
      • Removal speed scales with quantity (Tested on i7-9700 CPU)
  • Note: After installing this mod, you can no longer summon Wither Skulls using commands.
  • This mod can be added to modpacks.

# Compatibility:

  • Built for 1.20.1, but should theoretically work on all versions above 1.18.
