  • This mod is currently being rewritten, it's recommended to wait for the rewrite to be finished.
  • The rewrite should be done before february march may june 2026.

Sprinting

Undead mobs will sprint to their target if their target is near.

A Group of Undead mobs can violently leap and crash into a block causing it to break if enough damage was done.

Compatibility

  • Practically compatible with any mod. [this mod only adds on existing minecraft code]

Note

  • This mod does not store any extra data! Therefore, if a mob was breaking a block and the server restarts, the progress of breaking that block will be reset!
