This is an exceptionally basic plugin that retains the vanilla feeling of Minecraft which allows you too use those excellent enchanted items you found in The End or else where.
Simply take your Iron Chest Plate, helmet etc. Pop it into a smithing table with a clean matching Diamond equivalent and hey presto! You have an upgraded Iron item.
I'll overstate that I am a noob developer with zero prior knowledge of coding. Feel free to take the plugin and do whatever you want with it, just comment so I'm aware :)
Bug fixes can be done, but very slowly as this was used as a knowledge project. Coded for 1.17.1 but should work as far back as 1.13. This does not support Legacy.
You will need Java 17 too run this :) Java Downloads | Oracle
