I was attempting to complete the Stein of Moggok quest with out killing the fish in the paladins pool in North Qeynos by giving the dog Frostbite, in West Karana, the potion of Regurgitonic. I tried everything I could think of to get him to give me the fish but he would do nothing but give me back the potion when I handed it to him. I tried barbarian illusion and alliance, faction was kindly, with no results. I tried human illusion and alliance, same. I even tried to kill Frostbite, no fish and alot of negitive faction hits. He just does not appear to have the fish at all.
