Would be nice if XP from other mods could be used for the enchanting/disenchanting stuff.

My derp there, meant interchangeable with xp fluid from mob grinding utils or ender io (once it ports).

There is no such thing a Forge XP Compatible, each fluid is different.

Seconded, one way to solve this would be to allow the sewer block (Animal byproduct recollector) to suck up exp orbs and convert them to essence, that's how it used to work in MFR

As a secret feature, the Mob Relocator picks up xp orbs in its working area

Ooooh nice! That works fine for me :D
