I was discussing this issue with a few people and we decided to test out whether or not Back Stab took in to account whether you were duel wielding or not. It appears that the code does not look at whether you duel wield. I was curious whether anyone else thinks that if you are duel wielding it should make it more likely for you to hit or if it should add to the amount of damage if you do hit or both? I was thinking it should at least add to the likely hood of you hitting. I mean if you are skilled and using two weapons you should be twice as likely to land a hit and if you hit with both sheesh it should do a lot more damage. Just a thought.
