Thinking basic mage ops - gather intel on spells affecting a province. Seems like a good fit for paladin role, low difficulty shows all spells affecting target province (all relations). This is a spell, not thievery. Alternatively make it a spell available to more race / personalities, overall I just think there is little to no effective way on gathering mage intel and I think it being a spell is a good fit similar to how you use thieves to get thief intel.
