I haven't tried yet in this modpack, but the options I've thought of are, grabbingg some spawners with a diamond dolly and then using the item from botania that enables them to work without player presence or going the wrath cage route within forbidden magic.Question for those that are also further along in Blood Magic:
Other than the whole "Lighting everything up and making a vanilla Mob spawner", have you found any good way to automate LP generation?
