Okay so, if I have three perk points into Magic Resistance and then put a point to Atronach, would they effectively stack and I would only be affected by 40% of incoming spells? With 30% being blocked and the other 30% being absorbed. Or do they 'ocupy' the same 30%, one perk nullifying the other? i.e. having a point to Magic Resistance turning Atronach's 30% into 20%.
