Very nice set. Fits perfectly alongside the Gleaner and her spells, which are also mundane in application.
How does it work, though, adding spells to pre-existing domains? I can see it sort of, but I'd appreciate some structure, especially for spontaneous domain functions and the like.
I'm currently make an alternate version of Cleric which has more than one spell for each level of a domain as part of its main features. If your game only one per spell level, then I suggest you keep the domains untouched.
