They do not drop xp from a well of suffering.You could try the Well of Suffering from Blood Magic coupled with an upgraded sewer. I think mobs killed that way still drop XP, but you'd have to check. It does involve you being fairly deep into Blood Magic though
MFR grinder -> mob essence -> MFR auto-enchanter + glass bottle = bottle ole enchanting. I have about 1.3k of them sitting in my AE system.
Also, I don't want to use Grinders because they use Mob Essence.
