Altar of the Zombies Enchantment

So this is an enchantment that essentially lets you build an undead army in Minecraft. This Enchantment is for swords, and it's books can only be obtained in Temples, such as Desert and Jungle Temples. Probably a 12.5% chance of being in one or something. This enchantment, when put onto a Sword allows you to Use (Right Click) the weapon to turn a zombie into your ally. This enchantment weighs heavily on the weapon however, and when it's effect activates, it decreases durability by 10. Also, when the weapon breaks, all allied zombies become hostile again. The zombies effected by it stay in place, and attempt to deal damage to all hostile mobs in a 16-block radius.
