Sooooo i would like to attempt a different kind of playstyle. Maybe some kind of "ethereal spirit soul warrior" character who uses conjured stuff as well as shouts. Was wondering how do conjured weapons compare to smithed legendary weapons.

For example, how does bound sword compare to a daedric sword, and how does it compare to a daedric sword (legendary)?

The uesp wiki wasnt exactly too clear on this; the wiki seemed to be saying that the sword is of a daedric level. Just need some confirmation anyway.

Try a redguard with this build. There is lore about sword singers that could create a sword from nothing. As far as damage I think when perked out the sword ends up being like a daedric epic. But I'm not sure about that.

I prefer normal weapons over conjurable ones.
Firstly there usually easier to find/upgrade, I think?
That just my opinion.

With conjured weapons, i wouldnt have to find them though yea i cant upgrade them. Still i just wanna try for my soul warrior kind of character.

Best thing to do is just give it a shot and see how it goes. Sounds like a legitimately good play style. However, I haven't got into conjuration very much so far so I'm not entirely sure about that.

Bound Sword with Mystic Binding perk does slightly less damage than the base line Daedric Sword. A Daedric Sword improved to Epic then enchanted on top of that will do considerably more damage. That said, if you have high weapon skills you'll already be doing so much damage with a Bound Sword you wouldn't need the extra damage from a smithed/enchanted weapon.
