I'm not 100% sure on this one...
It's KINDA like the same for the flame staff, the maelstrom flame staff GLOWS LIKE MAD when you use elemental wall. However when you use another flame staff it doesn't.
I think some weapons have different (glow effects) visuals, I think this is the same case but I CAN'T be 100% sure mate.
I'll ask around, if I get the answer I'll be sure to respond
Alrighty cool thanks I been asking my guilds and many people in zone but no help...
