This plugin enhances the unbreaking enchantment. From unbreaking 1 to 30 only, anything above will not work.
This plugin is easy and simple, no commands or permissions. This plugin is useful for servers that want to add custom items. Such as items that aren't diamond but want them to have a decent amount of sustain before breaking.
This plugin should work for any versions below 1.16 if not please notify me.

I don't recommended using any unbreaking above 10 in version 1.9+ unless the item material is leather or gold. If using high sharpness weapons in 1.8 I recommended unbreaking 15 - 30 and in 1.9+ unbreaking 5 - 15.
