Hey guys,

I made new tools and I want to make them unenchantable.

By overriding getItemEnchantability() with return 0; I can make them unenchantable in the enchanting table but enchanting with books works anyway

Someone may have a more graceful way to do it, but there is a tick event for items in your inventory.  Just check for enchantment and remove if detected.

 

Blocking it would be less of a load, perhaps you should look at enchantment books and see how they work to find a way to block it.
