Ive used a couple of different builds,but currently i have
100% mana cost reduction on Destruction and Conjuration spells
300 damage daedric sword (lvl 70 skill, 4/5 armsman)
250 damage daedric bow (lvl 55 skill, 3/5 overdraw)
500 health
400 stamina
and some other stuff
This was after taking fortify one hand off a few peices, because 500 damage seemed like a bit of overkill.
This was all done without a single exploit, yet here i sit feelinglike im cheating. After all that work though, im not ditching crafting skills. Thoughts?
