Harry Potter and the Prisoner of Azkaban Cheats

On the Glacius challenge (you play it as Harry) there are icey ramps
that you slide down. At some points you will come to a split path (the
ramp divides into two ramps). Whenever you come to a split the game will
tempt you to take the left path by placing more valuable treats on it.
However every time you take the path to your right, you will find a
challenge shield! 

You will first come in contact with Hinkypunks on the same level with the Ghoul. 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.

How To Get Fairy Wings:
Collect Fairy Wings for your homework assignment for Professor Snape at Hogsmeade which are the woods outside Hogwarts. Use Hermione and cast Flipendo (Knockback Jinx) when the fairies come out and when you hit them they will fall to the floor. Then use the Glacius spell and freeze them before picking them up.
How To kill A Salamander:
Defeat Salamander by using the Glacius spell to put out the fire on its back and make it icy before shooting it with Flipendo (Knockback Jinx).

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.

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).
