At the main menu (with the D-Pad) press Up, Left, Down, Left, Right, Black, Black and White and you will be invulnerable.

To find Goliath of the Giant Card Set, use Reparo on the broken vase on the sixth floor. It'll cheer up Glanmore Peaks.

To find Lady Carmilla Sanguina of the Vampires Card Set, let Hermione use Glacius on the fire in the Gryffindor Common Room.

When you have to collect Fairy Wings as part of your homework assignment for Professor Snape you will get the chance to go to Hogsmeade (The Woods outside Hogwarts). When the fairies come out, use Hermione and cast the Flipendo spell (KNOCKBACK JINX) and if you hit them then they will fall to the floor. You then have to use the Glacius spell and freeze the fairies, then walk over and pick them up.

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.

To get Fireseeds, go outside then go to the right. Keep going until you see the greenhouses. There is a tree here. Have Hermione go up to the tree and use the Glacious spell. When the fire is gone, Fireseeds will appear.

Speak to Glanmore Peakes on the Sixth Floor.

When you have to collect potions ingredients for Snape, and the doors are locked in the great staircase, go to the first floor and try to open the door four or five times. You should drop down underneath the staircase. You can do this as Hermione, Harry, and Ron.

Fly in through the top with Buckbeak, using Hermione as the rider. Dismount when inside the courtyard and find a puddle of water. Use Glacious to freeze the puddle and it will turn into an ice block. Have Hermione climb the ice block and set the dragon statue on fire with Draconifors. The dragon will light up and blow fire. The fire will burn the rope that the crate is hanging from, and it will fall. Because you only have a limited time to go to the Quidditch field, just fly Buckbeak as fast as possible. The field will be where there is a tower with four colored flags. Once you see them, land on the green next to the tower to complete the task.

Once you get the Expecto Patronum spell, for a short amount of time you can go anywhere without being detected. All you have to do is cast the spell and just move the spell around as if you were trying to hit a Dementor, but instead of searching for a Dementor, you can use this spell to spy around corners and around open areas. This is a very useful for when you have to escape Hogwarts grounds at night and there are Security Trolls as well as Prefects. Note: You cannot use this spell to kill Doxys, Red Caps, or any other monster; it only works on Dementors.

In the Boys' Dormitory, have Harry as the active character. Look at the trunks. Find the trunk that has an "H.P." on it. Only Harry can open it. Inside has a Wizard Card. Switch to Ron as the active character. Find the trunk with "R.W." on it. Inside is yet another Wizard Card. The same goes for Hermione in the Girls' Dormitory, except her trunk is marked "H.G.", and inside is a piece from the Folio Bruti.

Go to the Second Floor and stand behind the large statue of Gregory The Smarmy. As Harry, look up and target the candlestick. You may need to stand back to do this -- be careful if it is at nighttime, as the Prefect may see you. Use Carpe Retractum on the candle, and on your left a secret room with a chest will open.

Go to Gryffindor tower and play as Ron. Search the bookshelves. One will open to a room. Go through the door and down the steps, then go to the right. Go down the staircase and open up a wall. It will lead you to the fourth floor.

To open the locked chest in Muggle studies, have Hermione cast Reparo on the Phonograph next to it.

Even though Buckbeak flew away with Sirius there will be a new Hippogriff by Hagrid's hut. This one is orange and its name is unknown.

The Hippogriffs only let Harry and Hermione ride on them. They will attack Ron if he tries.

After you approach the end of the game, where Dumbledore will tell you to finish unfinished business and then attend the House Cup Ceremony, notice that each time you go outside and visit Buckbeak he will be a different color.

If anybody is falling behind, press [L] to call them.

Throw a dung bomb by them and you can easily slip past.

Another way to get past the Trolls in the north wing of the seventh floor is to use Hermione. Use the Glacius spell on the Troll to distract it then run away. It is not as easy as using dung bombs, but it will do the trick. If you are not careful you can still get caught using this method.

In Snape's dungeons, at the side of the bar door you will see another door. Go there and have Ron use Lumos. Keep going between the bookshelves. One of them has a Prefect. If you catch him by surprise, you will get told off and start back in the dungeon's corridor.

When owl racing, if you fall behind rapidly tap [B]. You will catch up.

When you need to get to the Gryfinndor Tower and it is locked, if you are low on dungbombs, play as Ron and search through all of the bookcases. If you do not have at least four, you can go out to the grand staircase and immediately come back in. It will all be there again.

When you get Expecto Patronum for Harry, fire the spell in any direction and use it as a guide for seeing what is ahead.

During the school day, if you go to the Great Hall and start dueling, you will have the same team everyday. However if you turn off your Xbox, restart the game, then go to the Great Hall, you will face a different team from a different house.

For easy Lumos, press whatever button you have it on quickly, then press it again and hold. If done correctly, Lumos should just shoot out of Ron's wand without you stopping. Note: You must do it very quickly on the first time, then just it press again and hold.

Go to Fred and George's shop, located on the Sixth Floor. As Ron, purchase some Stink Pellets. After doing so, Fred and George will offer you a challenge, in which you must go around the school and throw Stink Pellets in the twenty mounted decorations, which resemble two snakes holding up a pot, tipping them over. After doing this, return to the shop and you will be given four Witches and Wizards Cards.

Go to the sixth floor (Ancient Runes) and go into the room with the picture that talks. Use Reparo on the broken vase and it should bring itself back together. Then, the portrait tells you how to get one of your potion ingredients. However, his speech is difficult to hear due to the noise of the books and the Reparo spell.

If you have Ron as the active character, the walls that are secret areas and can be opened have a glazed, foggy look to them. Also, when up against the wall/bookcase, it will say "Open" whereas if you have Harry or Hermione as the active character, the secret area will say "Try" when pressed against.

Play as Ron and go to the Gryffindor common room. Search the bookshelf. It will open and reveal a treasure chest. Inside is a page from the Folio Bruti.

If you are down on health and have no Wiggenweld Potions, go to the dueling club in the Great Hall and duel. If you win, your health will go back up to full. The same thing happens if you lose. After obtaining the first of the Wiggenweld Potions, use a potion on any character in need, then take that character to a pot, bush, etc. that "shakes". Fire Flipendo at it until it gives up a prize. You may have to do this to a few different objects. However, if you have as many beans as you can carry, it is easier to get a Wiggenweld Potion. Do not buy any potions; just keep hitting objects until each person has their fill of each potion.
