When black shield is active on a target, every Volley arrow does dmg that hits it.
Edit: until fixed I call it buckshot vs morg.
Volley does physical + magical, are you sure it's not the physical dmg that you are seeing?
um like 8x150dmg = a big bug. That's around 1200 from volley on a black-shielded target, at close range of course.
