Can get day cycle buffs based on atronomy, ie. ‘Madness’ general increase most stats significantly, but with lowered vitals, unable to craft or gather loot or maybe loot drop colors are randomized (ie. rare loot that is usualy blue appears white, and normal loot appears epic, etc). Can possibly synergize with the Librarian profession class, librarian maybe can ‘forecast’ what the next day’s affliction will be based on astronomy and old tomes, etc.
Different schools of magic i dunno
Instead of schools.. the way they cast the spells?

Pact or Possessed Dude Through familiar or elemental or demon?
