Harry Potter and the Prisoner of Azkaban

If you get poisoned by a Doxy and run out of Antidote to Uncommon Poisons, drink two Wiggenweld Potions. The game recognizes that you’re still poisoned after the first Wiggenweld, but not for the second.

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.

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.

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.

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.

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.

You can get lots of beans and Wiggenweild Potions in Fred and Georges bathroom. Play as Ron and go to the back room. Go up to the robes and press X for both sides. Beans and sometimes Wiggenweild Potions will appear. Go through the secret wall, then go back to Fred and Georges. Go to the robes and do the same thing. Keep going back and forth and you will have plenty of beans. Also when using Harry, Hermione, or Ron, fire your attacking spell at a bush. A bean will appear. Continue to do this as many times as desired.

When you are exploring the Hogwarts grounds, you will every once in a while encounter a bush. When you see one, move up close to it and shoot Flipendo at it. Either a jelly bean, antidote potion, or wiggenweld potion will pop out. Pick it up with the character of your choice.

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.
