Harry Potter and the Prisoner of Azkaban Cheats

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).

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.
