In this level you’ll need a Regular Wizard, Digging Character, and Dark Wizard.
Shoot the yellow flower in the bottom right corner, then shoot the plants surrounding the yellow circle. Put the pieces together to make armor, and shoot it. Follow the directions it points in to move on to the next area, where you’ll have to do the same thing. Start by shooting the yellow flower, then kill the Cornish Pixies, put together the armor, and follow its directions. The next part has two flowers you’ll need to shoot, and use Lumos on the vines to get the armor and follow its directions once again.
Try not to get hit by the moving walls and go through the small doorway cut into the hedge. Shoot the next yellow flower, then destroy the Boggart for the character token for Fleur (Lake Task). Continue along the maze, destroying any plants with Lumos. Eventually you’ll reach a point where you can see the Gryffindor Crest piece to the left behind a hedge, and some Cornish Pixies to the right. Kill the Cornish Pixies, take the arrow, put it on its stand, and rotate it to enter the next part of the maze.
Go forward and to the left, shooting the next yellow flower. The last one is to the right, between the two walls, and to the right again. Shooting it will give you the character token for Cedric (Maze Task). The Student In Peril is directly behind you, being strangled by some vines. Shoot him to free him. Go forward and to the right, near the digging area, and destroy the plants with Lumos for the Hufflepuff Crest piece. Open the book and build the springboard to jump over the wall. Clear away the vines and levitate the fly onto the spider web, then do so again to destroy the walls. Build the fly again to scare away the sphinx and walk to the trophy to move on.
To get the collectable in this area, you have to be playing as Cedric. Destroy the Death Eaters, but ignore Voldemort for now. Levitate each of the skeletons to earn the Slytherin Crest piece. Now, switch to Harry and fire the spell back at Voldemort. Destroy the Death Eaters and fire the spell back at Voldemort twice more to end the level.
Near the beginning of the maze area is a wall that needs destroyed by a Dark Wizard. Destroy it with Crucio, then have a Digging Character use the spot to dig up the Ravenclaw Crest piece. Right before entering the third area of the maze, destroy the wall here with Crucio to get the Gryffindor Crest piece. In this same area is a digging spot; use a Digging Character to dig up the character token for Viktor (Lake Task).
