I have recently made a custom bow (ItemRubyBow) that is pretty much the ItemBow code copied but modified. So I was left clueless when, even though every other thing was working perfectly, the bow would only get the enchantment "Unbreaking", no matter how many times I enchanted it. They were different levels of Unbreaking, in case that is relevant.

 

Also, this may be related to the answer: Is there any way to set the durability of a bow?

 

Am I missing some sort of "BowMaterial"?

 

Here is my code: http://pastebin.com/7EX5BFTk

Bump. 

Bow enchantments look for ItemBow. Extend that class and you should be fine.

*Hint* Copy-paste = Baaad  .

Durability is based on the item damage value.

Thanks, that helped a lot!
