I googled it and it is listed as missing in several places I looked. I'm not sure what to tell you on that one, perhaps someone else has info. It may be a old achievement?
Chase Nibbles from F.S. Distillery: The Rum Cellar [Solo] is the description. I only did the quest once when it first came out, think you just kick him or something in the last room.
I have searched and searched to no avail. Thank you for your responses. I went back and ran the rum cellar [solo] again, kicked Nibbles, killed Nibbles, still nothing. I just can't figure it out. You would think if it were an old achievement, they would take the item off the merchant that stands in front of the rum cellar doors. If anyone has any info or anything at all, it would be greatly appreciated. Thanks
Don`t leave the room when he flies around dealing damage, just suck it up and kill him - if you leave the room it won`t update iirc.
See http://eq2.wikia.com/wiki/Aerial_Burial?fbconnected=1&cb=4447 for the full description. The quest is called "Aerial Burial".
