If I am going DW ranged with either the Gunslinger’s jacket or talisman, do the effects of Dual Blades and its tree affect the ranged combat, or would they be wasted points at that point?
Yes, the Night blade DW skills only work with melee weapons.
I thought so from the description, but I thought I would check. I can always buy the points off when I get the Gunslinger item.
