Good thing I don't use offensive magic huh? I've got a sword, and crossbow to kill you with. Also you're not the only one who's resistant to magic.

Whew! Good thing Dragon Hide lasts for only 30 seconds, and takes about a year to charge up huh? Also its a good thing bows do ridiculous damage, and stagger right?
Oh I forgot your targeting AI svcks and all I have to do is juke side to side to dodge...
Also, I thought the point of you "charging up" your restoration magic was to do something potentially lethal to undead like...heal us?
Does healing work for negative damage against undead in Skyrim???
Also, if that's the case with Dragonhide then I don't need it. Ebonyflesh. +200 armor. Bam.
I hardly ever use the flesh spells any more since I get stealth kills all the time. Seriously, stealth 100 is broken.
Guard/bandit/dragon/Giant/anything: "What was that?"
Walks up to the PC so close you can feel its breath on your face.
Turns around and leaves.
"Probably my imagination"
Except the initial "What was that?" never happens because stealth 100 is just that broken.
Okay so you detect me. So I don't sneak. I just straight up kill you in a fair fight.
Point is I still kill you.
