does anybody know where the three stones beneath spellhold are? ive got 2 and cant find the third. also, does anything happen when you place the objects into the statues hands (level 1 beneath spellhold)?

Good questions. Those are the two things I never finished there. I also only found 2. I did get a crystal shard later that I think is the third, but I never tried it - once you go through a certain exit, you can't go back . And I didn't have any saved games...

Hmm I think you are missing the one you get for solving the puzzle with
the strange items. There is a chest containing several strange items and
several statues in a room. You have to place the right item on the right
statue to get a stone.
