61 SK here doing the turn in. I tried running the various methods below since I was KOS by the entire room with Teydar. I tried dragging him to the zone, then FD'ing and doing the turn in but he walks away very fast and has his pet with him. I tried killing his pet then FD'ing and doing the turn-in but as soon as I went FD, he recasts his pet.
The only successful way for me to do the turn-in was to invis, get behind him in his normal spot, click invis off by initiating trade, putting the stuff in, hitting cloudy potion, and hitting the trade button.
It took me 1 or 2 times, but I was finally able to do it quick enough to not get aggro before re-invising.
VERY TRICKY! but if you do what I did you shouldn't have any issues.
