Once you have put fluffy to sleep,beet the devil snare, got past the chess game and made the troll fall down the pit, Hermione will have opened the door. A game is played. The knight you'll need is the with the sheild.Keep you eye on the bell he's under, then hit the bell with you spell, and use two charged Knockback Jynx on it.p.s. He'll have a shield so wait till he has swing at you then use your charged spell on him. DO this again an hell, die and drop a potion youll have drink it,and run through th fire. In the next room there will be 4 knights, repeat what you did before. A giant knight will then appear. Get close to him, wait for him swing,run out the way and hell become visible and shoot him with a charged spell and keep doing this for 5 to 6 times and you'll defeat him. Go across the bridge and in to the other room.To get past part 1 of Lord V. wait till he's next to pillar
and use a charged spell on the pillar. Ropes will stop you from moving, so just press square over and over again. Part 2.This is simple: wait till he's on the other side of the mirror and use charged spells on the mirror for 3 times and repeat,
dodge his spells. Part three: Press square and x together repeatedly and a quick fire pad wont work, I've tried. Watch the end sequence and save your game.
