okay. i got a clue scroll that says
"The rock cakes to the south
are definitely more edible than the
rocks I buried the treasure between.
Does anybody know what it means??
Go to Gu´Tanoth ( the ogre city south of Yanille that requires starting Watchtower quest to enter.), There are two two big rock heaps just north of the Rock cake stall. Dig between them.
Hmm, try runehq, they might know!
