Hello
It seems that the items in Symphony of Blades arms pack are similarly bugged as some other crown arms pack were previously. The weapons itself are lighted but they do not emit light or cause ambient light around them. Here is a comparison between the Symphony of Blades staff and Iceheart staff (sorry, another one is a destro and the other is resto but I guess the effect itself is visible nevertheless). It can clearly be seen that the Iceheart staff illuminates both the character and the wall, but Symphony of Blades staff doesn't do either.
