Find Goliath of the Giant Card Set
To find Goliath of the Giant Card Set, use Reparo on the broken vase on the sixth floor. It'll cheer up Glanmore Peaks.
Find Lady Carmilla Sanguina of the Vampires Card Set
To find Lady Carmilla Sanguina of the Vampires Card Set, let Hermione use Glacius on the fire in the Gryffindor Common Room.
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.
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.
