Maybe there could be an item that could be added so you can continuously gain experience over time. You could craft multiple of them and they could store 50-100 levels of exp each. The recipe could contain several hardened obsidian, nether stars, dragon items, and other rarer items. Just something I thought might be a good thing to add.
This is a cool idea! A way to store amounts of experience, maybe you could make custom glass (Hardened Obsidian + 24 Glass panes = 24 Hardened Glass?), and use those to craft bottles that could store an amount of xp! Maybe have different magnitudes of bottles too? So a cheap one that wouldn't cost much hardened glass but would only store 20 or so xp, all the way up to one that would cost lots and store 300 xp? Not too sure about the numbers there but I like this idea a lot
