Mob Battle Mod (Create Easy Mob Fights)
Mob Battle Mod takes care of that by adding item which will help you in creating (and maintaining) mob fights. This is meant to be played in creative mode. It is explained ingame, how to use every item. This should work on every mob, which can fight back. With other words: Every fight possible can be done with this mod.
This mod introduces a series of wands that enable you to take control over who or what a mob attacks. The Enrager is the main wand that you simply click who want to do the attacking and then click the next mob for it to attack.
