I have not played in a very, very long time, but I remember before I quit that I spent almost all the money I had on the site on a weapon for my avatar. I'm sure it was a staff or a scythe or something, very dramatic and took up the full height of my avatar. When I logged back my avatar was a broken image and in my wardrobe I cannot see that particular weapon any longer. Was it removed from the game for some reason?

It was the one marked here as shinigami I'm pretty sure.

Could this be the item you're thinking of?

If you believe you're missing an item on your account, it's usually best to submit a ticket so a staff member can look into your account logs for you.
