Hellay's Xp Containers

A lot of new changes thanks to our new member MosquitoCoding!

Here's the full change log:

• The xp bottle and xp jar now work with xp points instead of xp levels. This means that you can no longer get more points out of the jar than you put in it

• The recipes are cheaper now and use diamonds instead of netherite ingots

• The items click behaviour has changed. Now a simple right click stores xp and shift right click retrieves all xp from the container to your hotbar
