Occultism

A ritual magic system centered around summonable spirits allows you to automate various tasks, store vast amounts of items, let demons mine in void dimensions, create powerful enchanted tools and jewelry, get support from familiars, and much much more. Begin your journey by crafting the Dictionary of Spirits, and following that in-game guide, discover the secrets of the spirit world, find otherworld groves hidden in plain sight by gaining the "Third Eye", and finally summon your first spirit.
