Are bound weapons daedric? I want to know how strong they are.

Yes that is a good question, how much damage does my bound weapon do, is there a way to see and compare it to a "normal" one?

Do 1-Handed Perks works with bound Weapons?

An finally when im Dual-Casting my Bounded Sword it is automatically put in to the left hand, as I′m only able to wield my shield in the left hand also, it is not possible for me to use a dual-casted bound 1.hand weapon + shield.

Either I need a way to put my shield into my right hand, or to spwan the Bounded weapon in the left hand after a dual cast

(PC-Version)

Dual casting conjuration spells just makes them last longer, it doesn't increase their strength or anything. Considering that, dual casting a bound weapon spell doesn't really benefit you very much.

Not sure about the 1h perk question

Done a tiny bit of testing with bound weapons - hitting with the battleaxe (2h bound weapon) my 2handed skill improved.

I would guess that means the whole 2h tree works just fine with them. In essence, they are likely treated like just another weapon in terms of perks.

Going to be playing more on my conjuration-warrior tomorrow. I'll try to update any interesting info I find.

If you check inventory and your weapons with the bound sword equiped it shows it's dmg.
Also as far as I can tell all the one handed perks effect the bound weapons as well.
However i'm not sure that bonuses from enchantments like 10%bonus to dmg on rings works.

Oh checked further regarding bonus damage from ring enchantments and it actually does work.

In other words I think it should be pretty viable to use bound weapons as long as you pick the right perks.
