Title says it all actually.

Illusion magic makes you overpowered against everything very soon, no matter on what difficulty you play.

Is there a mod that changes that?

So far I′ve tested two:

a) Empowered Magic allows enemies to resist the spell when applicated and under the effect of the spell, like frenzy.
But the resist-chane even on "bandit leaders" and Co is way to small in my opinion. My illusion mage is lvl 8 though; does this change later on, someone knows?

b ) SkyRedone has the best sounding solution; it simply overhauls the school.
However, I do not have Dawnguard, and when installing the non-Dawnguard version, I don′t get any of the new spells (in fact, I keep the old ones like Fury, where the description of the mods suggest they are erased from the game).
Anyone having experiences with Illusion magic in SkyRe?

c) Any other usefull input?
