In this level you’ll need a Regular Wizard, Dark Wizard, Parselmouth, Digging Character, and Goblin.
Shoot the painting to the left to get rid of the barriers. Go near the open toilet stall and put the tunnel part in place. Have Ron send Scabbers in and press the wheel to make some more pieces, then switch to Harry or Professor Lockhart to get the vines off the door of the next stall, free the Student In Peril, and levitate the next part of the tunnel upwards. Get rid of the vines on the next door and fix the tunnel again to have Scabbers climb through and complete the maze. Open the chest, put the plunger together, and ride it to the right toilet to get the pieces to the entrance. Have Harry use Parseltongue to open the chamber and let you through.
After falling down the hole, put together the first skeleton. The second one is to the right of the first, outside of the small cave you started in. The third one is in the top left corner behind the digging spot. Go up onto the left and raise the plunger to get rid of the squid. Put together the pieces you’re given and have one of the other characters raise you up. Go across and put together the final skeleton, giving you the Gryffindor Crest piece. The water will help you get to the next platform to put the pieces together and make a bridge. Climb inside the snake’s mouth and go through the tunnel to the third area.
Have the basilisk crash into the rocks to the right of the spiderweb on the wall. Open the rock to have the skeleton dance and fall apart, then take his arm as an ingredient for the potion. Now have the basilisk destroy the rocks to the left of the spiderweb and use Parseltongue on the snake for another ingredient. Have the basilisk destroy the rocks to the left, open the rock, kill the snake inside, and collect the final ingredient. Pull the chain on the left to have Fawkes attack the basilisk. Attack the basilisk and after it goes underwater, levitate the accordion on the left. Go to the right and levitate the violin and trumpet to get the Slytherin Crest piece. Pull the two chains on the green tube on the left to lower it and jump in. Levitate the Sorting Hat and finally, raise the sword to stab the basilisk and end the level.
In the second area, there are four spots that need to be dug up by a Digging Character. Two are in the middle of the area, one is on the ledge to the left (where you used the plunger to stop the squid), and one is in the area after crossing the bridge. Digging up all four of these spots will earn you the Hufflepuff Crest piece. There are also two character tokens in this area, Gilderoy Lockhart and Wizard (Green). On the ledge to the left are two boxes. Use Lumos to get rid of the vines that cover them and use a Dark Wizard to use Crucio on them and get the tokens.
In the final area, there is a chain on the wall to the left. Use Reducto to blow the chain off the wall, then put together the pieces to make a birdhouse. Doing so will get you the Ravenclaw Crest piece. Finally, after making the basilisk go underwater, go to the top right corner. Use a Goblin to open the vault to get the character token for Tom Riddle.
In this level you’ll need a Regular Wizard, Digging Character, and Dark Wizard.
As with the other levels taking place in the forest, shoot the bees’ nest when the level starts. There are some brown mushrooms to the left; activate them before pulling the plantlike vehicle out of the ground. Ride the vehicle and jump out to reach the higher ledge, then activate the mushrooms there (one in the middle of the area, and one in the bottom right corner). Shoot the grass away to reveal pieces to make a cloud, and levitate it over the tree to build a ladder for the rest of the characters to climb up. Use Fang to dig in the spot underneath the tree, climb across, take care of the bees, and activate the mushrooms here (again there is two, one at the top and one at the bottom). Use Lumos on the vines to get the brooms out, fly across, and shoot the bees’ nest. Fly the rest of the way across to the other side and shoot the bees. Build the ramp into the water to help the other characters up. Activate the two mushrooms here and one to the right, then climb the ladder and go left to get the character token for Ron (Sweater). Now go right and shoot the bees’ nest, and activate the two mushrooms here for the Slytherin Crest piece. Take care of the Cornish Pixies to find a digging spot for Fang.
Once down, you’ll have to fight a bunch of spiders, including Aragog. The Student In Peril is to the right of Aragog; shoot him to free him from the web. To defeat Aragog, avoid the brown spiders until you see a black spider. Shoot it and toss it into the air to make Aragog lose a heart. Do this two more times to move on.
At this part, you’ll be driving and running from Aragog. There are five boxes in this area; two in the first part, two in the part after the cutscene where you jump off the cliff, and one in the final area. Run each of them over for the Gryffindor Crest piece.
The Ravenclaw Crest piece can be found in the lake. Where you cross the lake on a broom, there is a silver gate to the left of the bees’ nest. Use Reducto on this gate and ride the frog through each of the checkpoints to get the piece. Not long after crossing the lake, you’ll see a glowing chest. Get a Dark Wizard to destroy it with Crucio to get the character token for Professor Sinistra.
While fighting Aragog, there is a glowing red sphere to the left. Destroy it with Crucio for the Hufflepuff Crest piece. To the right there is a locked chest. Use Reducto on the lock for the character token for Lucius Malfoy.
In this level you’ll need a Regular Wizard, Dark Wizard, Goblin, and Book Character.
When the level starts, Moaning Myrtle is throwing things at you from inside the stalls. Throw them back at her and shoot her when she pops out of the stalls.
You’re now in Tom Riddle’s diary. Shoot the armor to the left of the bookcase, then the bookcase to get a potion ingredient. Add it to the cauldron to the right, and go farther right and shoot the armor. There is also one to the left of the cauldron. Get rid of the vines nearby and levitate the plank to make a wardrobe. Go inside to get earplugs for the Mandrake. Use it to break the glass nearby and pot it; then jump on the three wheels on the bottom to make platforms. Once up, go to the left and shoot the armor, then the pot to the left of that to get another potion ingredient. Now go to the right and levitate the wheel off of the wall and onto its stand. All three wheels below will stay down now, making for easier and faster travel upwards. You can go add the ingredient now, or switch to the other character and grab the next one, inside the bouncing chest. Drink the potion and pull the chain to get more pieces. Stack them up, jump up, and climb across to get the final two armors and get the Gryffindor Crest piece, then pull the chain up there and go through to the next part of the level.
Go forward and use Tom Riddle to use Reducto on the chest, then shoot it to open it and get the Ravenclaw Crest piece. Jump on the wheel to switch the staircase, and shoot the radio before climbing up. Shoot the painting to get the wheel for the next staircase. Shoot the second radio here, then rotate the gate to let the other character through. Shoot the black and white banner on the wall and make it into a springboard. Jump up and use Lumos on the vines, then levitate the springboards to their spots on the wall. Jump up and shoot the final radio to get the Slytherin Crest piece. Now you can switch the blocks on the arches around to leave the level.
In the first area where Moaning Myrtle is throwing things at you, use Reducto on the chest to the left and use the plunger to clean up the puddles. Doing so will give you the Hufflepuff Crest piece. On the far right, there is a red glowing chest that needs destroyed with Crucio. Destroying it will give you the character token for Moaning Myrtle.
The Student In Peril can be found in the first part of Tom Riddle’s diary. Use a Book Character to open the bookcase to get him out.
As you enter the second part of Tom Riddle’s diary, there is a vault. Use a Goblin to open it to get the character token for Vocalist. There is another vault at the end of the level, near the final radio. Use the Goblin to unlock it to get the character token for Professor Vector.
In this level you’ll need a Regular Wizard, Strong Character, and Dark Wizard.
Levitate the hair off of Crabbe and Goyle’s heads to get the first ingredient for the Polyjuice potion. Go the whole way to the left and use the broom to knock over some stuff on the shelves. Pick up the wheel and put it onto the gas chamber. Turn the wheel and the second potion ingredient will be given to you. Jump on the toilet lid to the right and turn the wheel. After jumping across all four lids, the fifth one will explode. Levitate the faucet up and then put the flower back together, opening the door to the third stall and revealing the final potion ingredient. Add the ingredient to the cauldron to advance to the next part of the level.
Go down the stairs and put the three fish back into the water to get the Hufflepuff Crest piece. Use Lumos on the vines through the right doorway and empty out the box, then put the pieces together to make a flute. Shoot the snake in the mouth each time it comes out and some pieces will be left behind. Put them together to make a suit of armor, which will stop the water and let you advance to the second room of the Slytherin dorms.
Levitate the two lamps on the wall as you walk in. Put the broom in the chimney and put together the pieces to make a painting. The man inside will help the Student In Peril down from on top of the glasses. There are two more lamps on the wall behind where the Student In Peril was. The final two are in the next room, and activating them will give you the Ravenclaw Crest piece. Open the orb to let the fish out, then go to the fish tank and levitate the skull out. Put its eyes onto the snake to end the level.
In the girls’ bathroom at the beginning of the level, use a Strong Character to pull the chain by the gas chamber. Build the plunger and use it to get rid of all of the green spots on the floor to get the Gryffindor Crest piece. The character token for Vincent Crabbe is also in this area; use Reducto on the barriers to the right to reach it.
As you enter the second Slytherin dorm room, there is a black sphere. Get a Dark Wizard to use Crucio on it to get the Slytherin Crest piece. There is also a chest by the chimney that you can use Crucio on to get the character token for Gregory Goyle. The final character token is Ron (Slytherin Disguise), and can be found by using Reducto on the box in the room to the right.
In this level you’ll need a Regular Wizard, Strong Character, Slytherin Student, Goblin, and Dark Wizard.
When the level starts, raise the two flags. Open the trapdoor and climb through. Open the box and hit the thing that comes out to drive the Bludger through the wall. Put together the pieces to make a springboard. Before bouncing up, go the whole way to the left and shoot the flag in a barrel. Then bounce up and shoot the second flag, and shoot Dobby to make him disappear. Use Hagrid to pull the chain and climb across, then shoot Dobby again. Use Immobilus on the two Cornish Pixies and then use Lumos to make the vines disappear. Put together the pieces on the ground to make a staircase, but before climbing up shoot the third flag in a barrel. The final barreled flag is to the right of the ladder that Dobby climbs up. Shooting it will give you the Ravenclaw Crest piece. Now climb up the ladder and raise the two flags to get the Hufflepuff Crest piece. Levitate the rock up to open the door.
Climb up the ladder and shoot Dobby. Use Hagrid to pull the chain, then stack the blocks on top of each other and climb up. Shoot the middle cupboard to release Dobby, then shoot him. Jump down and kill the two Cornish Pixies to make them drop the planks. Climb across and shoot the barrel, then use Wingardium Leviosa to levitate Dobby out. Hit him one last time.
You are now in the hospital area of Hogwarts. Use Madam Pomfrey to blow the lock off of the closet, then switch back to a student to put on earplugs and pot the Mandrake by destroying the glass. Take the flower off of the plant before potting it to get an ingredient for the potion. Levitate the skull onto the skeleton to get the arm for the potion. Jump on the bed to the left to get the character token for Dobby. Raise Draco’s bed and put together the pieces to destroy the lock on the door, then go through.
Brush away the spiderweb. When it reappears, brush it away again to get the spider ingredient for the potion. After putting it into the cauldron, the level will end.
In the first area of the Quidditch match, go right before building the stairs. Use a Dark Wizard to open the chest using Crucio to get the character token for Draco (Quidditch).
In the second area of the Quidditch match, use Lumos Solem on the chest below the lockers. Then use Reducto on the lock to free the Student In Peril. Levitate the scroll onto the wall close by. Use a Slytherin Character to wave at the painting, then do the same on the other side (after you cross the bridge). They will give you the Slytherin Crest piece.
In the second room of the hospital area, use a Dark Wizard to blow the lock off of the drawer to get the character token for Madam Pomfrey. Use a Goblin to unlock the vault and get the Gryffindor Crest piece.
In this level, you’ll need a Regular Wizard, Digging Character, and Dark Wizard.
The level begins in the Weasleys’ yard. You have to rid the garden of gnomes using Wingardium Leviosa. Getting rid of all six will earn you the Gryffindor Crest piece. Put together the pieces in front of the basketball hoop to make an orange car. Run over the leaves sticking out of the ground and then use Wingardium Leviosa to shoot them into the air. The Hufflepuff Crest piece will appear shortly after. Then, go into the Weasleys’ house.
Go into the living room and find Ginny (behind the blue chair). Go over to the portrait of the Weasleys and they will give you an item to put inside the fireplace.
You are now inside Borgin and Burkes in Knockturn Alley with Hagrid. Use the broom to clean off the mirror and reveal a chain that Hagrid is to pull. The hand will release some pieces that can be put together to make a sword. Levitate the sword into the painting and the man inside will give you a key. Use the key to unlock the shop and go out into Knockturn Alley.
Shoot the large red jack-in-the-box to get pieces to make a chain. Have Hagrid pull the chain to remove the display. Go forward and shoot the spider, then go forward more to a brown chest. Open it to get the token for Harry (Sweater). Have Hagrid pull the final chain a little bit ahead and go through the gate to end the level.
Near the basketball hoop in the Weasleys’ garden is a digging spot on the ground. Use a Digging Character to reveal the character token for George Weasley.
In Borgin and Burkes, use Reducto on the silver chest where you start the level. The Student In Peril is inside. Destroy the fanged chest nearby and go inside. Use a Dark Wizard to destroy the sphere with Crucio to get the Slytherin Crest piece. There is also a chest near the door that needs destroyed with Crucio to get Arthur Weasley.
In Knockturn Alley, the Ravenclaw Crest piece is plainly visible through a walkway. Use the boards inside of the wagon to build stairs, and use Crucio on the gate to open it. Now the piece is easily reachable.
