Lots of changes!
You now can combine 2 books and not only 2 items.
Enchanting cost is now
properly calculated. If you want to understand how it's calculated, check this website:
Anvil mecanics
Autodect server version to enable/disable the posibility to rename in color. Check this website for the
Formatting codes
You can configure the 40 levels maximum (Too expensive) in the config.yml
Big thanks to
@Jikoo for letting me use the code from his plugin
AnvilUnlocker to achieve this.
You can now configure max level for each enchant.
Some code cleaning...
