LEGO Harry Potter Collection

This achievement is for Lego Harry Potter: Years 1-4.

First, let me point out this is an extremely glitched achievement (at least it was for me), and required four playthroughs as a result.

Make sure your Xbox One is set for Energy Saving mode and always quit the game properly when you turn off your system (or even decide to take any kind of break).

This is why:


200/200 Gold Bricks, yet I didn't get the achievement. I went on to get 100% in that playthrough and the rest of the achievements in Years 1-4 (including ones you can't get without meeting the requirements for this achievement), and then got every achievement in Years 5-7 but still didn't have this achievement, so I did a fourth playthrough.

Always try to get Students in Peril (in the Hogwarts HUB) first in each section (or at least not last). For that matter, make sure you actually see him or her (if possible) before you attempt your rescue. Also, do not exit Hogwarts HUB immediately after rescuing a Student in Peril. That ended my seen playthrough, as seen here:



Finally, use the exploit to get Reducto early (see below) AT YOUR OWN RISK!

NOTE: I decided to edit the next part on Chaotic Fiasco's advice. It should add up to 200 gold bricks total.

Here's where you can find the Gold Bricks:

1. Leaky Cauldron, Diagon Alley, Knockturn Alley, and Gringotts Wizarding Bank: 28
2. Story Levels: 96 (24 each for completion, Students in Peril, True Wizard, House Crests)
3. Students in Peril: 26 in the Hogwarts main Hub
4. Hogwarts: 35
5. Lessons: 15

It helps if you use the Gold Brick and House Crest Detectors. If you don't want to look for them in Hogwarts, here are the codes, which can be entered at Wiseacres Wizarding Supplies:

Gold Brick Detector: 84QNQN
Hogwarts Crest Detector: TTMC6D

NOTE: Using codes should NOT affect achievements. However, if you're worried about it, here's where you can find them in Hogwarts:

Gold Brick Detector: Use the Time Tuner on the clock in the Owlery, then go up to the tower.
Hogwarts Crest Detector: Ravenclaw Common Room

NOTE: You can purchase them at Eeylops Owl Emporium. (You can also purchase 12 gold bricks AND find a 13th one by sweeping the floor.)

If you're looking at getting Gold Bricks quickly, there was an exploit in the original game that made it into the Collection. In Year 1, Harry gets the Invisibility Cloak when you play the Restricted Section story level. After the level, go to the class hall in the Hogwarts hub. Then, to get past the Prefect on the flight of stairs on the right, activate the cloak and enter the Transfiguration classroom. When you complete the lesson (you need to complete it anyway if you want the achievement), you unlock the Transfiguration spell.

Here’s a video that shows the exploit working:

NOTE: When I did the Expelliarmus lesson, I kept turning Draco into frogs and mice. However, I was still able to unlock Expelliarmus (and can still use it if I want) and get the Gold Brick, so it should NOT affect the achievement.

Now pause the game and select Return to Leaky Cauldron. Exit the Leaky Cauldron through the left, then look for Professor Quirrell. When you find him, cast Transfiguration on him, then press to possess him. (NOTE: I tested this personally and it worked on my first try.)

NOTE: Before I continue, I should point out that the one time I did this exploit (it was my third playthrough trying to get this achievement), I couldn't get into Slytherin Common Room. I used The Bloody Baron to open the door, but then my characters fell through the floor every time I tried to enter the Slytherin Common Room, so it's possible the exploit prevents you from entering the Slytherin Common Room. You have been warned!

This is how my third playthrough ended:


Now, you can cast Reducto on the gate leading to Knockturn Alley. There you will find the character tokens for Igor Karkaroff (who has Reducto and Riddikulus), Shifty Wizard (Reducto, Riddikulus) and The Bloody Baron (Slytherin Character). You can purchase them at Madam Malkin’s Robes for All Occasions. Why is this important? Because once you unlock the Polyjuice Potion, you can turn into them at the Polyjuice Cauldrons.

Other characters you need for getting to gold bricks and Students in Peril faster (NOTE: You can use any character you want if they meet the requirement for the gold brick or Student in Peril you’re after. I’m just including ones in this list you can get early on.):

Mrs. Mason (Age): Muggle Artifacts Room
Hagrid (Super Strength): The Forbidden Forest story level
Tom Riddle (Slytherin, Parseltongue, Dark Wizard): The Basilisk story level during the boss fight

With the exploit, you should be able to get all the gold bricks in Hogwarts in year 3 after you get the Time Tuner. You should just need the few remaining spells, story level ones, and ones you get placed and purchased in Diagon Alley.

Here’s a video that shows the free roam Students in Peril you can find scattered around Hogwarts:

While you’re going for this achievement, you’ll also unlock:

Just a small tip as people had/have ended up one gold brick short on this version and the 360 version. In Hogwarts free roam, you may need to revisit Hagrid's garden in Year 4 and complete the slug vomiting puzzle. There is another puzzle here but you may have already completed it, if not use the time turner clock in the back left corner.

Upon completion of the slug vomit puzzle, a cutscene prevents the brick from being collected so after the cutscene, when you respawn, head back to Hagrid's garden and you should be awarded the brick.

Additional notes based on comments: Some Gold Bricks require Time-Turning to collect; one of these areas is Hagrid's Garden, tying into the original solution. The Gold Brick Indicator does not display until you are in the correct time version of that room for the brick's acquisition

Hey Gamers! I have finished a complete 100% guide for the LEGO Harry Potter Collection. This particular achievement is tied to getting all the gold bricks in the Years 1-4 portion of the game. I have made a complete collectible guide to cover all story missions as well as the hogwarts and diagon/knockturn alley hub areas. I hope you find this helpful. Every collectible is also timestamped within the description and comments section of the video.
