thanks for all the help.  I just though without getting the crystal fragment, I woul not be able to finish the game.  I got the mushroom and all the ingredients, and when I go to fight the shaman, he just kicks my butt after about a 4 minute duel.  Everytime I whiddle him down, he heals himself.  I will just try harder, maybe try some traps.  has anyone tried scorpion traps on him?
thanks again for the help!
