Just did this today, with all the tips in here went very easy and I will add one more I didn't see. Shrouded as a rouge to start. As I got a wizzy port to icefall first thing I did was /warp s. I clicked sneak targeted stonefed conned him to see I was indifferent used '/saytarget can help' to get quest. I then clicked hide found the cave and got the quest update picked up a stone and /warp s again. use clicked hide off and /ubertrade to do turn in. I then did /stealth on and warped back to the stones in the cave. Using stealth at the zone in allowed me to not use hide while I picked up a stone and remain indifferent to stonefed so from right there I could use /ubertrade to turn it in.
Thanks for all the tips, and hope you enjoy this one
