For Ender IO, a broken spawner is usually fixed by combining it with a Powered Spawner in an anvil, or by changing its mob type first with a Soul Vial in a Soul Binder and then using it with the Powered Spawner. In other words, the broken spawner is not “repaired” back into a vanilla spawner; it is used to set the mob type for an Ender IO powered setup.

How it works

  • Broken Spawner comes from breaking a mob spawner and keeps the original mob type.
  • Soul Binder + Soul Vial can change the broken spawner to a different mob type.
  • Anvil + Powered Spawner + Broken Spawner makes the powered spawner spawn that mob.

Common setup

  1. Get the mob you want into a Soul Vial.
  2. Put the Soul Vial and Broken Spawner into a Soul Binder to convert the spawner type if needed.
  1. Combine the resulting Broken Spawner with a Powered Spawner in an anvil.
  1. Power the spawner with energy and it will start spawning mobs.

If it still seems broken

  • Make sure the room is dark enough and that you are close enough for the spawner to activate.
  • If you are using a modpack like Better Minecraft or Spirit, the fix can be different from Ender IO’s method.
  • A vanilla mob spawner that was broken with a pickaxe is generally not repairable in survival without cheats or replacing it.

Short version

If you mean Ender IO broken spawner , the fix is: Soul Binder for mob type, then anvil it with a Powered Spawner.
