Overall XP is a mod that allows us to create an experience storage system that is easy to make and use. With this mod installed, if we place an emerald in the center of the crafting table and surround it with iron bars, we will get the XP block, which is an experience reserve.

This block will allow any player to store experience, in the same way that it will allow any player to extract experience from it. If we want to store experience in the XP block, we only have to press Shift plus the right mouse button on the block, this way all our experience will be stored in the block. Whereas if we want to remove experience from the storage block to save it in our experience bar, we will have to right click on the block. In this way we will obtain an experience level for each click that we make on the storage block.
