So my setting is very Moorcockian with Law, Chaos, and Balance as viable PCs and antagonists (being chaotic =/= gribbly insane and evil in my world).
So I was thinkimg about proficiencies that might let a caster have greater effect versus their opposites…so something like Lawful Casting: Chaotic targets suffer a -1 to saves versus your spells. Balance characters might pick a specific alignment to target (or lawful and chaotic inflict a -2 and balance gets a -1 vs both).
What do you think…too powerful? Not powerful enough?
