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

How To Get Fairy Wings 
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. 

How To kill A Salamander:
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 (Knockback Jinx). 

Defeating the fire armor:
When fighting the fire armor thing when you just got Glacius, to avoid the shooting 
fire rocks when he opens up, stay directly in the middle. You should be able to 
avoid almost all of them.

Start with Flipendo until he opens his mouth, then use Glacius until he sort of 
explodes (this does not mean that he is defeated). One of his arms will come off. 
Use Glacius to put out the fire, then use Flipendo to destroy it. Repeat until he is 
defeated. 

Defeating the metal armor:
He will try to spin around to attack you. You must dodge it, and when he stops, use 
the spell that grabs things. You must grab each of his four shields. When the 
shields hit the ground they will turn into monsters. Once you kill all four, he gets 
swords. He will stop spinning. Wait before you grab his head with the spell, 
because he will hit his swords on the ground. After he does this, grab his head and 
yank it off to defeat him. 

Defeating the Goul:
On the "Neville And The Goul" level, after you have completed all of the tasks and 
have opened the chamber, light Lumos Duo in its eyes. Then, lead it into the 
chamber to lock it in.

Defeating Hinkypunks:
You will first come in contact with Hinkypunks on the same level with the Goul. 
Hunkypunks are ghost-like creatures with one foot and a lantern. To defeat them, 
have Ron shine Lumos Duo in their faces. When they become solid and zombie-
like, finish them off with Flipendo.

Character special abilities:
Each character (Harry, Ron, and Hermione) has a special ability. Use Ron to find 
hidden passages. Use harry to jump long gaps. Use Hermione to crawl under small 
spaces. This is useful when getting spellbooks or escaping Trolls and Prefects.

Harry's Dad's voice:
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.

Gryriffindor ties and clothing differences: 
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.

Defeating Dementors:
Clear out the Dementors in the middle then go up to the Dementors that are 
sucking the soul out of Sirius and attack them. The health meter at the bottom will 
go down. Keep attacking until you defeat it. Do this quickly, as Sirius only has a bit 
of health.

To defeat the Dementors in the first stage (where you drag Sirius Black), do not 
wait until the Dementors are sucking the soul out of Sirius. Hit any of them that 
edge closer with Expecto Patronum. After a few hits, the first stage will be over.

The second stage of the Dementors is much more difficult. There are many more. 
Shoot Expecto Patronum at the Dementors (do not power up as Sirius will get 
weaker), and press X to charge at them. Break through the crowd in the back. 
Once you have a path cleared, go for the Dementor attacking Sirius. Power up 
until it automatically shoots. Remember to press X to charge and go faster. If you 
take too long the Patronus will die down. 

Getting Doxey eggs for Potions class: 
Have plenty of Antidote because Doxeys are poisonous. Use Flapindo to get rid of 
the Doxeys, then have Harry use the spell that grabs things, Carpe Retractum, to 
pull the eggs towards you. Hold the Analog-stick Toward you to pull them. 

Getting Fireseeds for Potions class: 
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.

Unlocking the locked door and chest: 
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.
