I want to follow birds around in a hooded robe carrying a lituus and warn my villagemates about bad omens.
We have animism, haruspicy and other forms of divination and lots of other fragments of ancient roman type spiritualism, so why not augury??????
Also I feel like all these spiritualisms needs to be organized in to larger and more focused industry/mechanic that can be tied together and expanded in to a larger thematic chunk of content.
The idea of having a "village spiritualist" character archetype that provides some sort of useful service sounds awesome though.
