Fiendfyre Frenzy mission

We are looking for a diadem that is another Horcrux. Go all the way to the right and find 3 cauldrons standing on top of each other - shoot them with a wand and use one of them.

Move Hermione on the pink platform and take a large dustpan and broom out of her purse. Remove the web and collect the red spider. Throw the first ingredient into the cauldron.

Switch to Ron, use the orange box and shoot the rocket. Take the green fan lying on the ground and bring it to the wizard in the picture. In return, we get blue ice, which is another ingredient of the potion.

Then we knock down the pot with a yellow flower and switch to Hermione. Summon Crookshanks and dig up the last potion ingredient. Blow the obstacle up and move on.

As Hermione, you have to solve the puzzle from a bookcase. Use the bricks to create a shield and put it in the knight's hands.

Jump on the shield and take the glasses. Notice the invisible bricks at the bottom and use them to build a catapult - use it to destroy the second obstacle.

Switch to Ron and use Deluminator to take the light from the lamp. Transfer it to the lamp on the table - the soldiers will unlock the way forward.

Approach the large scale and destroy three silver items with Reducto spell.

The pipe element we are looking for will fall down. Pick it up and put it in the right place. Now we move the part of the wire to the right place.

Switch to Hermione and summon Crookshanks - move it inside and press the button.

The pipeline will open on the other side - go there. All the books will fall over like dominoes.

During the fire, we must go through the following levels. Extinguish the flames in your way. Go all the way to the right and jump to the upper floor. Use Wingardium Leviosa to rotate the car - the friends will go to the other side.

Go all the way to the left, destroy the silver stool with Reducto and climb up the pile of furniture.

Extinguish more flames, switch to Ron, and pull the fireworks out of the orange box. Fire them so that we can move further to the right.

Use your wand to shoot at the cabinet to rotate it. Remove the red bricks and build a ladder out of them. Climb up.

Use the broomsticks to fly from one platform to another and then start the pumps one after another. The water stops the fire from spreading - you have managed to save two Slytherin students.
