Ahh, good ol' Spells be Effective...I'll install it ASAP, thx!
No magic penalty for wearing armour any kind? That's kinds lame... :S, sorry to butt-in like this but don't you like your game difficult?
At Master armor levels, an extra 5% of spell effectiveness barely affects difficulty, and certainly doesn't for me at all. I've no problems at keeping my game challenging, even at lvl 50.
My secret? HP capped to 100, and no über gear (maybe except the sword, which does 129 damage + 22 Absorb Health). Still, certain enemies (mainly from mods) takes forever to kill.
