EnchantedCombat | Endlessly Customisable Items [Free]

EnchantedCombat is a plugin to allow for creating custom items quickly and without needing to know how to code. This means you can write your own abilities for items you design without writing any java. It also comes with a plethora of stock items to provide examples as to what you can create.

Installation is simple: Download SkillsLibrary and EnchantedCombat from spigot, and place the Jar files into your plugins folder.

However, this isn't fully comprehensive yet, so I highly recommend joining my discord and talking to me in #my-plugins. I typically respond (at least) within 24 hours of a message in there if you want to ask a question.
