To keep this short, I’ll get to the point.
I want to maximize my efficiency running AC exp and CoF exp. I notice that my AC weapons glow while I’m in those dungeons. AC weapons only glow at night. I’d like to put a universally efficient Sigil on one weapon, Superior Sigil of the Night, but I am not sure if the damage would be equal to having two individual weapons, one for AC with Ghost Slaying and another for CoF for Flame Legion Slaying.
tl:dr Are AC and CoF nighttime?
