LEGO Harry Potter Walkthrough Year 3, Level 3: Mischief Managed

Published on July 14th, 2010

There’s quite a lot of spell making in this level, so you’ll need to find all the ingredients. Some are very well hidden, so check out our guide to find them all!

In the room where you first start off, you need to find two keys to unlock the door. The red key is high up in the left-hand corner of the room next to the cobweb. Levitate the fiery torch on the side wall and burn down the vines that are wrapped around the key. You then need to levitate the key to the lock. For the yellow key target the wardrobe on the right side of the room and then build a statue. Shoot at the statue and it will release a key. Once again levitate it to unlock it. Now turn them both, you’ll need two characters to do this simulataneously.

When you arrive at the next open room there’s a number of things you need to do, including finding the ingredients to put in the cauldron. First up, you need to find the cauldron. There’s a large wardbrobe on the right hand side of the room. Hit it and then build the cauldron. Now for the ingredients. In the centre of the room put the blocks on top of each other in this order – Green, Red, Blue. Hit the Skeleton with a spell, grab the hand and put it in the cauldron.

There’s a small chest to the right of the main door. Hit the chest to reveal a snake and then target the Pixie (blue spell) who’ll drop a hammer. Levitate the hammer to smash the snake and you’ll get the second ingredient. The final ingredient is on the left side of the main door. You’ll need to target the object high up on the back wall and you’ll get the last ingredient for your strength potion. Now drink the potion and pull the heavy chain to exit the room.

In the next section, you’ll need to find the three ingredients to make an invisibility potion. The cauldron is trapped by vines so burn them away with your Lumos spell. There’s a spade near to the cauldron, use it to dig and you’ll find the first ingredient. Now go back to by the entrance where you came in and use the Riddikulus spell on the boggart (spider) in the chest. Switch to Harry and use him to speak to the snake. You’ll then be able to build an object that lets you go down the side of the building where you’ll find a spider’s web and the second ingredient. Target the fountain on the lower level and then build it so you have a wheel you can turn that gives you access to the upper level. The final ingredient is on the upper level. Stay out of the way of Argus Filch and the cat and jump through the window in the centre of the balcony to get the chicken leg.

Put all the ingredients in the cauldron and then both characters should drink the potion at the same time to go invisible. You can now both go to the upper level and walk past Filch without being seen. You’ll need both of you to activate the pully system at the same time when you get past Filch. You’ll open the gate and you can now leave the area.

To exit the next corridor, just target the small chest on the left hand side of the room and then build a cello. That will play and the man in the painting will drop a key that you can levitate to the lock on the left hand wall.
