Im not sure about this change, I need more details....
Does this mean in province 1 you get 1 A relic first fight, 1 A relic second fight, 1 A relic third round, 2 A relics fourth round, 2 A relics firth round, and 2 A relics in sixth round? meaning in total 9 A relics from 1 province? province 2 then you only get B relics, and province 3 you only get C relics?
In other words can you focus on certain provinces so you only do those that give you the relics you really want? or is it more like round 1 A relic, round 2 B relics, round 3 c relic?....
how exactly can you do the relic requirement change, if you just switch the requirements a bit around, that means nothing changes there, since most of us, constantly make the same spells all the time. Meaning we will just drain other relics from then on.
I can only see a way to make it good, if you can turn x relics of choice into some basic relicresource, and that those relicresources are then required for any of the spells.
