I’ll put this in the “Miscellaneous Resources” category…
Any Class Warfare experts out there? Johnstone Metzger , you around? A question about Disciples. The Devotion move all Disciples get specifies they pick three spheres of influence. The Embodiment specialties has a move that says to pick a particular sphere of influence, and then its casting move says you can cast spells “from your sphere of influence”.
The way I am interpreting this is that all Disciples (e.g. at least two Disciple specialty) characters have three spheres of influence they have special knowledge of, but the specifics about which spells they can cast are determined by the speciality specific moves. So in the case of an Embodiment, they have three specialities with special knowledge (from Devotion) but only one sphere they can cast spells from. In fact, that one special sphere might even be different from the three chosen for Devotion.
Does that sound right?
