I just started a new rogue and I was glancing at the tool tip for Ambush and the way the tool tip is worded it makes it sound like you can have the dagger as either the off hand or the main hand to receive the extra amount of damage. After doing some tests in game I can't really see if having it as your main hand or off hand really alters your damage bonus.
My question is, does having your dagger in the main hand or off hand make the damage bonus apply? If it does actually matter is there any chart or stats someone could provide that would show me actual proof? Thank you.
