(I added "Eversight Ring from act 2, and Helldusk helmet from act 3" to the effects that grant sight in magical darkness section. I don't know if it's a bug, but I tested this and with the eversight ring on, I was able to cast spells and shoot into the darkness. But upon removing the ring, it made my character run into the darkness to cast/fire. It also allowed me to fire out of it. I haven't got the helmet yet, but it has the same wording, so I'd assume it works the same.)
