This made me pretty happy right here. The great part of this was that I was lurking around Kamadan and had just said to an in-game friend, "I really wish I could find an air celestial staff, 20/20"
Then, a few minutes later, literally, I saw someone spam "WTS Celestial Staff Q10 20/2 Air Olds. wsp me + Offer", out in trade.
I didn't waste time. I asked him C/O, he said 30e. I asked him B/O, he said 50e. I asked if he would take 45e and he said yes. We traded and I am a happy Elementalist.
