Hello!

I'm fairly new to this game again so I just wanted to ask a few questions regarding gear/equipment. I see some characters with high level armor that is dyed. However, whenever I wear or have high level armor and gear I can't seem to dye it. How do you get to dye high level armor? Is it only some armor or do you have to complete a mission for that?

Also, how do people get those really shiny weapons with those nice particle effects? They look so cool T.T
