in the desert where the agreesive turtles are..they are big turtles....they are in area #1

Complete the quest with the sand wyverns(get 3 piscine livers)and in the rewards screen, you should get at least one.

you can get it in the slay the yian kut-ku quest in forest and hills area.. you can get
both money and med.monster bone there.. just kill the wyverns.. I use bowgun there.. go to
the area where you can find velociprey and 1 vespoid.. kill the velo and wait for kut-ku
there.. vespoid will always respawn, so kill it once it respawn.. you must climb the
ledge, so kut-ku won't hit you.. if the kut-ku fly to the ledge, just jump down, it can't
go down.. that's an easy path..
