What is a black weapon?
I have heard the term floating around as related to min-max damage increased weapons, especially in relation to the new ruby effects in the 1.07 PTR.
What is a black weapon?
Black damage on a weapon means there is no elemental affix damage to that item. IE: Fire, Cold etc. It will have the min and max damage. There is a bug with the calculations and a Black Weapon paired with a triumvirate for example will up your damage because you get the elemental affix's on that, it really boosts your damage.
