Defeating Venomous Tentecula
To beat the Tentecula, run back and forth and make
him spit poison at you. Use Diffindo to cut off one arm then continue
to run back and forth. Cut off the next arm. Immediately cut off
the head and shoot Incendio (power up for a few seconds, but not
too long or the arms will grow back) at him. You should defeat
him in a few shots. There are two Tenteculas.
Defeating Devil's Snare
The Devil's Snare is exactly like the Tentecula, but
much easier. Cut off his arms and his head then shoot Incendio
at him. This time do not worry about running back and forth. Stay
still and he will not hurt you much.
Defeating Trolls
You have multiple encounters with trolls. Find a Spongify
tile and shoot Spongify at it. Wait for the troll to run at you.
Then, jump on the tile towards the troll. He will hit the tile
then hit himself on the head.
Get to the nearest Spongify tile and get on it. Then, target it
and charge up the Spongify charm. Wait for the troll to start
the attack, then release the charm.
Extra Chocolate Frogs with Voldemort
If you have used the three frogs in the battle before
Voldemort (Gytrash), do not worry. You can get these again. Save
the game in a safe area in the middle of the battle. Then, exit
the game and reload it. The frogs will be there again.
Invisibility Cloak
This cloak is not too helpful. Prefects will still
catch you. The most you can do is not touch the Prefects. Filch
can usually find you, even if you do not touch him. If you do
get caught, even without the cloak, you will not get House Points
taken away from you.
Gargoyle statues
There are mean looking statues of gargoyles all over
the teachers' quests. Light Lumos in front of them and they will
reveal a hidden path.
Hidden items
Search all of the desks in the classrooms. They contain
Beans, Cauldron Cakes, Pumpkin Pasties, Stink Pellets and even
Wizard Cards.
