"When the ogre is chasing you, follow the line of Bertie Bot's Beans so you'll know where to jump over the missing floor boards." - Nan

"if you don't know how to beat Voldemorte when you battle him you flippendo the mirror in the middle so it faces Voldemorte and when he casts a spell it will backfire on him. Keep on doing this until he dies." - no lies

"When tipping the columns on voldemort, stand behind them and wait while he shoots about 5 green spells. Then he moves between the column and the mirror. That's when you flipendo it onto him. Make sure that as soon as it starts to fall you move because sometimes Vold's last spell sneaks under the column as it falls.

When you have pushed enough columns on him to knock down half his life, the rest of the columns explode and that's when you have to rely on flipendoing the mirror. The straight spells are fast but you can dodge them. It's the slow ones that follow you that are hard. Stay aware of where the statues are because if you run backwards fast enough to get behind one of them the slow, following spells are stopped by the statues. " - pickled slugs

"The Lumos challenge wizard card is in a secret room behind the large, round stained glass window at the end of the long hall with 3 lumos rectangles. (Also 2 wall light arrangements have chests with beans.) Anyone else know of other hard-to-find cards? I can't find all 24." - Olivander

"Gnomes are tough. Don't back up too close to walls -- it makes your view so you are looking down on Harry's head instead of from behind him, and this makes aiming almost impossible! Be patient as you enter a room SLOWLY (or even just before you enter) and they sometimes don't start moving. One of the 3 gnomes in the secret area behind 2 alohomora bush walls will eventually come to you before you go through the second bush wall -- jumping backward onto the bridge gets you back faster so you have time to aim your flippendo." - Norbert
