Let players keep their Inventory and/or EXP on death if they have a certain permission node.

This plugin was designed for the Server staff team or VIP players. Simply give the group the keepitems permission and they will keep their Items and Armor on death, optional experience too. This is perfectly if you don't want to use the game rule "keepInventory".
