I have defeated him twice now , the papers reveal them selves but i cant use them ,i cant move to the next phase of the quest any help here thx ?
Are you sure that you still need "Lord Bramble's Tower"? Or do you still need "The Crystal Tower"? Open your quest log file and look at the name on your quest. It sounds like you already did pick up Lord Bramble's and you need to go to The Crystal Tower and fight Lord Graustark.
This link shows details on the Pigswick Papers in case you need it:
