The Rebirth of the Night team would like to use the ancestral infuser as a means for crafting any assortment of magic items.

Since spirits can't be spawned normally (such as using InControl, due to them not being living entities), and since we have karate zombies disabled, the source of spirits is severely limited (we have added a temporary recipe to craft the spirit bottle)

Ideally, we would love a config option that allows us to list which mobs 'drop' spirits when they are killed, and how many spirits each mob drops. (Maybe more power/boss mobs drop more spirits than, say, vanilla skeletons.)
