This plugin adds potion armor. Potion armor is bascially normal armor exept it gives a permanent potion effect. The potion effects can be changed in the config file. Just set the potion to false that you dont want. To get the armor you need a smithing table, then put atleast 7 netherite ingots, the armor piece(supports all armor), and the potion effect. The chestplate will then get the corresponding effect from the potion
