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! 

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.

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).
