I've read stuff about one handed attack bonuses not benefiting daggers, I'm not sure if it's true or not.

It technically has always been a 1 handed weapon.

The one handed skill and perks affect it, but it doesn't benefit from the 'fortify one hand' enchantment or potion. It (along with every weapon) does benefit from a fortify marksman potion though.

No, its a two handed weapon.

yes wielding bonus enchants dont affect daggers ...any more, im sure they did...maybe to balance the shrouded gloves.

edit: or try to, hahahahaha

"trying to" fits well. you don't need more than the one handed perks to one shot everything with db armor

Do you hold it with one hand?
