Gratz! This is quite the undertaking. I'm working toward a weapon very slowly, because I can't figure out which one to get. The unicorn bow isn't really my thing. I don't love the great sword, at least not dusk. I guess I'll just have to try to figure it out as I see more of them in game.
You might not like Bifrost then since it's a rainbow staff. I've seen people with Dusk and it looks great from different angles. Sometimes it's red, sometimes it's blue depending on your proximity to it. Incinerator is nice, though it reminds me too much of a lighter.
