What about Prime Sources increasing a cap on the amount of Prime you can have? So if I am part of a council with, say, one Prime Source then I can have a total of 15 Prime, but if I don't have any other sources then the most I can have is 5?
Instead of over complicating things, there should simply be something like a council prime pool where each member can take out x amount whenever they need. Obviously this should be changeable since every council will be different but at the same time you want to make it flexible enough to make each council unique. I guess there could be two ways of doing this. vertical or horizontal. If you are looking to build a more traditional pantheon, probably building it vertically would be the best option where the head of the pantheon hands out the points.
