There’s no way for the staff to replace your specific item. I have dropped a god pick before. I think it would be best to spend your time grinding for a new one rather than making a post, sorry about this
As Kieran has said, there's no way for us to get the item back. Sorry for the inconvenience. I suggest moving your drop key far away from any other keys you may use so you don't drop things in the future, I have mine set to a button on my num pad. No possibility of accidentally dropping items. Thread Locked.
