Is there any way to get into this dungeon? I have five battlefield keys (guess a couple are jokers). I have finished 5 of the dungeons in the final battlefield (IV). I never could get the last dungeon unlocked. It left me with one quest to find a bow for Elkar (and one for the founder bone which I finished w/o the reward of course). Did anybody find her item? (The lady in the white robe).

Oh yeah, any use for the 'Holy Grail' or shold I ditch it? I heard it was good for a few magic points.
