Fiendfyre Frenzy
Fiendfyre Frenzy is the fourth level of Year 7 (Part 2) in LEGO Harry Potter: Years 5-7. In this guide, we will walk you through the entire level, so you can destroy the next Horcrux.
The Room of Requirement
This leg of your journey begins with Ron and Hermione in the Room of Requirement. Firstly, start by hitting the cauldrons on the right side of the room with Reducto to knock them free and start your potion making process.
There are three ingredients hidden around the area. The first ingredient is in a spiderweb near the ceiling. Switch to Hermione and use the pink platform in the center of the room to find a brush and shovel. Lift it toward the spiderweb to brush the first ingredient off.
Switch to Ron and open the Weasley Box on the right. Launch the rocket inside to make a fan fall from the ceiling.
Pick it up and give it to the overheating wizard in the painting on the left side of the room. He will give you the second ingredient as thanks.
Destroy the leg on the table on the left of the painting to find the third ingredient. Place it in the cauldron with the rest to create a bomb that clears your path to the right.
Head into the next area and switch to Hermione. Solve the bookshelf puzzle by repeating the symbols back in the same order to find a shield.
Hand the shield to the suit of armor on the right to create a platform. Hop on and cast a spell on the platform to lift you high enough to reach the top of the shelf. Hop off the platform and on to the shelf to grab yourself a pair of Spectraspecs.
Jump back down and craft a catapult out of the LEGO blocks in the center of the room. Launch it with your magic and make your way into the next area.
Switch to Ron and use his Deluminator to snatch the light from the left and give it to the lamp at the front right of the room. This will make the soldiers blocking your exit run over to feast on the meal next to you, allowing you to meet up with Harry and keep searching for the lost diadem.
There is a broken pipe on the left side of the next area. Press A to flip the broken piece around, and run to the right side of the room to find the missing part. Hit the scales with Reducto three times to lower the piece enough for you to pick it up and carry it back over to the pipe.
Switch to Hermione and send Crookshanks up the repaired pipe to push the button on the left. Then move Crookshanks to the right to knock a suit of armor onto the Diadem, allowing you to reach it.
The Dragon of Fire
Malfoy, who was also in the Room of Requirement, releases a massive dragon of fire that you now have to escape if you don’t want to be burnt to a crisp.
Run and jump over objects to make your way to the right, putting out flames with Aguamenti as you go. Once you get as far to the right as you can, the dragon will circle back around, knocking more objects down, which you can use to make your escape.
Turn to the left and press A to levitate the large LEGO block high enough for the others to pass over. Once they are safely on the other side of the burning rubble, they will lift the platform for you so you can join them.
Keep making your way left, extinguishing the flames so you can pass through. Once you reach a locked chest on the left, blast it open with Reducto and craft a staircase to climb higher.
Once you reach the top, head to the right and open the Weasley Box with Ron. Launch the rocket inside to create another path to the right. Keep moving until you reach a brown chest.
Hit the chest with Reducto to flip it around, revealing a Diffindo wall. Cast Diffindo and create a ladder to climb up and out of the flames.
Rescue Mission
Hop on the broomsticks Hermione finds in the burning rubble to rescue Malfoy and his friends. There are three water tanks you need to craft to rescue them.
Fly to a pile of rubble on the right and press X to hop off your broom. Hit the red object with Diffindo, and hit the white object with Reducto to clear your way to a Parseltongue puzzle. Switch to Harry to solve it and make the first of three water tanks to extinguish the flames. Fill the tank with Aguamenti to trigger the device.
Hop back on your broom and fly to the platform at the back. Jump onto the platform and rebuild the second water tank by pressing A to reassemble the pieces. Fill the tank with Aguamenti.
Jump on your broom once again and fly to the platform on the left. Blast the piles of stuff with your spells to get enough blocks to make a plane. Press X to jump on the plane and circle the platform before knocking down more rubble so you can create the water tank. Craft the tank and fill it with Aguamenti to save Malfoy and his friends from the flames and complete the level.
You are now ready to move on to the fifth level, Snape’s Tears.
