Harry Potter and the Prisoner of Azkaban

Have Hermione repair the dragon statue with Reparo. Then, shoot Draconifors at it to light the bush in which the fairies are hiding in. The fairies will get mad and attack you. Then, have Hermione shoot them with Flipendo then use Glacius on them while they are on the ground.

When you talk to other students, look at their ties. Everyone has a Gryriffindor tie, with the exception of Malfoy, Crabbe, and Goyle (whom have different ones). Also, there are only two people with their shirts out, which are Ron and Seamus, and with either Crabbe or Goyle, only one has a school jumper on.

When you get attacked by a Dementor and it is stealing your soul, listen closely. You will hear a male voice yell 'Lily! Its him run!' or 'Lily! Take Harry outta here!', which we can assume its his dad telling his mom to get Harry to safety the night Voldemort came and murdered them.

When you are helping to save Neville the Hinkypunks are the ghost things that Ron has to kill. All you have to do is back all 3 of them into a corner. Once they are there and you are close to them, they should not move anymore and you should be able to target and Lumos Duo each of them. When they become solid Flipendo them until they blow up. Do this for all 3 of them. After you do one group a second will appear. Repeat the steps above to kill them. After that shine Lumos Duo on the crystal for about 5 seconds until it lights up, then adjust the mirror so it shines in the eye and the gate on the far wall should open.

To kill a Salamander first use the Glacius spell to put out the fire on its back and to turn it icy and then shoot it with Flipendo.

Secret Passage 1 - The Great Hall: On entering the Great Hall located at the left handside of the staircase leading down to the hall, you will notice a brightly coloured light shining through the left-hand side window. Ron will exclaim "Harry, Harry, it's the Hagrid." Hagrid will appear in the Great Hall and show you a secret passage way located under the long table with the mat on top. Climb down.

Using Ron, you can discover Bertie Bott's Every-Flavored Beans in bookcases. Using this logic, this is how the trick works. First, enter a huge room with many bookcases (usually a study area.) Pick out the beans (or occasionally dungbombs) from them, and then exit the way you came. Enter once more, and you will be able to reap the beans again, even though you already did! This is an effective technique for gaining unlimited beans.

In order to unlock the locked door on the Sixth Floor and the locked chest in the Muggle Studies area, you have to find and return all of the lost objects from the notice board in the Gryffindor common room, until you find the key. It is located behind the statue on the First Floor. You can now open the door and chest using the lost key.
