Still in Hogwarts, the school is now under attack. Harry and Luna team up. Start the stage off right by using magic on the pull-string left of the painting. Three objects will pop out, a bird, a cloud, and the sun. Place the bird lowest, the clouds in the center, and the sun up highest.
Some hopping bricks will pour out. Construct them into a Spectrespec Dispenser, and take a pair! To find some hopping bricks, put out the fireplace right of the painting, then construct the invisible bricks. A hammer and chisel will appear.
Run downstairs and use magic on the chisel first to place it, then magically lift the hammer to hit the chisel in each spot it moves. Once the barrier is hammered enough, fire one explosive orange spell at the barrier to completely destroy it.
Continue right to find a cauldron below some stairs. That can mean only one thing, find the three ingredients. For the first ingredient, water the plants to the left of the cauldron. Up the stairs and near the window are invisible blocks, so get another pair of Spectrespecs now if you need them.
Construct the invisible pieces, then blast the dancing statue with an orange spell to gather your second ingredient. Next, use magic on the statue above the cauldron to set the stairs right, then use magic on the Slytherin hanger. That reveals a snake panel, so follow this pattern with Harry; blue, green, yellow, red.
The last ingredient appears in the snake head to the left. Turn the knight statue above the stairs again, then take the ingredient out of the snake head’s mouth.
With the cauldron active, drink the strength potion and pull on the orange handle to the right, ahead of the green slime. Construct the pieces, then magically move the set over the slime to collect it all and get it out of your path.
Continue right until a chandelier falls and blocks your path forward with fire! Fill the water container right of the fire with water, then use magic to move the container over the fire and put it all out. Run towards the ghostly figure to finish this section.
Next, you’ll join Neville and Seamus as they plan to destroy the bridge into Hogwarts. You need to place five explosives around the bridge. The first in on the left, in the foreground. Break the Lego box and pick up the explosive, a pointer will appear to show where it needs to be placed.
Run out onto the walkway and move right. Use blue magic to spray each of the plants with water to form jump pads, allowing both of your characters to bounce right. On the other side, you’ll see an explosives holder. Run down and look in the background for a vine-covered chest. Use Lumos to scare the vines, collect the explosives, and place the explosives where they belong!
Up the ramp, you’ll find a plank and a torch that can be magically lifted. Raise the torch up to burn away the Lego vines and free the plank, swinging left and red, allowing you to ride across.
The lower path isn’t easy either. Use magic on the first plank to raise it, then use magic on the second plank to move it into place – just connect the purple Lego piece to the other purple Lego piece. Jump across both, blast the cobwebs above, and place the explosive into the slot.
That’s three explosives placed, two to go. Cross the lower path, run back up the ramps and use the swinging plank to move right. Over the plank, run down the ramp to spot another red Lego wall. Shoot it with red magic, cut out the shape, and construct the blocks that fall out.
After a little show, a cobweb will be left behind to your left. Use it to jump up behind the wood, and blast the large Lego chest to find your fourth explosive. Set it, and continue right.
Right of the red Lego wall is a pile of Lego pieces. Construct them to form a set of stairs to climb, and run ahead to find a paw-print spot. Use Neville’s shovel to dig up the explosives, and set them. With all five explosives set, you’ll finish this section and start a new one.
Under Hogwarts, Ron is teamed with Hermione. In the background, you’ll see some green Lego vines. Scare them away with Hermione’s Lumos, or white spell, and use the pink baseplate. Lift the paintbrush she summons and paint the purple Lego surface above, make sure to get it all!
In the water, jump onto one of the Lego rocks to raise another rock even higher, allowing Ron to jump to the previously unreachable ledge left of the small waterfall. Jump to the top and have Ron use the Weasley Box to gain a pair of sticky trainers. Now Ron can walk on the orange and purple Lego surface!
Jump onto the Weasley surface, those big orange and purple pointers, and walk left. Jump to the ledge and use Ron’s Deluminator on the lamp. Jump down and move right and into the background, near a circular Lego door. The lamp is just right of the door, on the wall. Light it up and some hopping bricks will appear. Construct the bricks to form a snake puzzle. Use it with Ron, and follow this pattern; blue, red, yellow, green.
Correctly follow the pattern to open the circular door. Inside, move right until you’re stopping by a barrier. In the background, some Lego bricks are in a snake’s mouth, use magic to make more hopping bricks appear. Construct them into a pink baseplate for Hermione to use. She’ll summon a drilling machine!
Jump into the machine to drive it, and ram the rocks to drill straight through. Deeper in, use magic on the giant snake skeleton to reveal more hopping bricks. Construct those into a pink baseplate, and use Hermione again. She’ll summon a tweezers, useful for pulling the snake’s tooth out!
With that last task done, you’ll have another stage completed. Continuing the story takes the heroes back to Hogwarts and gives them another ghostly stud trail to follow.
