Custom Enchantment

how do I applicable custom enchantment?

 

maybe item -> addEnchantment(EnchantmentInstance(Enchantment, $level: int))
Enchantment class
EnchantmentInstance class

 

No. I want custumize custom enchants.

 

I think it will be interesting for you to look at it from the inside *click*

 

Take a look at examples that are already out there.
I also commented a little tutorial in PM3 in this thread:
