Feature:

The Enchantment Industry addon for Create is relatively new, but it's starting to get added to more and more packs. The Disenchanter block (Kind of like an item drain, except only for enchanted items and bottles of xp) will collect any xp orbs that land on top of it and convert them into liquid xp. However, it does not attract xp like a nephrite siphon does. It would be nice to somehow combine the two or make them more compatible. Currently, if a farm produces xp orbs, there's no good option to collect them into a liquid.

Something else that would help with this would be the ability to pump liquid xp directly out of carved nephrite. You can use a fountain and spam ~9 disenchanters around below it, but it's not very practical.

Enchantment Industry also adds hyper experience, a version of xp that is neon blue/turquoise instead of lime green/yellow, which is 10x concentrated. It would be super cool to be able to store it in carved nephrite. Even though it would be ridiculously expensive to get, that would be an incredible building block (and also a useful utility).

Alternatives:

Those are just a few ideas for things you could do with it, but I'm not the one who has to write and debug the code to make it work, so feel free to do with this as you please
