Hello, I have two mainhand sin daggers bought with tokens. I have purple ferocity gems in each. One of them has the manic haze blessing on it. When I wear that dagger with my T6 neck with manic haze on it I get no blessing. They are not working together in this case at least.
The other gem is Black Pharoah if that matters.
Also, it doesn’t matter if I equip the dagger in mainhand or offhand slot.
