Hello everyone, it’s time for Chapter Twenty-One of Year Five of our Magical Journey Walkthrough for Harry Potter: Hogwarts Mystery. In the previous chapter, you looked for Madam Rakepick, but couldn’t find her anywhere. Professor Kettleburn pointed you to one of the upstairs corridors where you encounter Percy’s pet rat Scabbers. Much to your surprise, Scabbers turned out to be an Animagus named Peter Pettigrew, who is in hiding. Before you had the chance to ask him everything you wanted, he used the Memory Charm on you and made you forget all about your encounter. Luckily, Madam Rakepick heard some parts of your conversation and was able to deduce that Peeves has the vault portrait. Now you have to find the poltergeist and convince him to hand over that portrait to you.

Before that, you can deal with the lessons. Proceed to the Charms Classroom for your first lesson of the chapter.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Unlocking Deletrius lesson requires earning a total of nine stars from Charms classes. Pick the combination of classes most suitable to your liking and hit the Start to begin.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

As usual, prioritize actions with a high cost in order to save some energy.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

And try to successfully complete all of the mini-tasks to gain some extra Empathy points.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Once you have all the stars necessary, head back to the classroom to attend the lesson.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Learning the Deletrius spell requires obtaining five stars within three hours. Since all of those are needed to pass, it is recommended to avoid starting this if your energy is low.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

In total, you’ll need around 55-60 energy to finish this task, depending on the actions you do.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Upon earning the fifth star, you’ll be tasked with performing the spell. Trace the wand movement on the screen to do so.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

For the second lesson, proceed to the Training Grounds.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

To unlock Agility Course – Thread the Needle lesson, you need to acquire nine stars from the Flying classes. Like before, pick the class combination you prefer and hit the Start to begin.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Actions that cost 5 energy are fairly scarce here, so you’ll likely need to spend more energy here compared to the other classes.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

And like before, focus on all the mini-tasks to earn some extra Courage points.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

When you unlock the lesson, head back to the Training Grounds.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

To complete this Agility Course – Thread the Needle, you need to earn five stars within eight hours. All of those are required to pass.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Be sure to check out character lines after completing actions. Some of those are quite interesting.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

When you earn all five stars, you’ll be tasked with demonstrating this maneuver. Trace the path on the screen to do so.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

What follows is a nice animation during which your character performs Threading the Needle. This will also increase your energy limit by one point, which is nice to have.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Now that you’ve dealt with the lessons, you can head to Defence Against the Dark Arts classroom to meet with Madam Rakepick.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

She will explain the situation and tell what needs to be done.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21 Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

She’ll suggest splitting in order to cover more ground while looking for Peeves. Your job will be visiting the house ghosts with one of your friends. You can choose to bring either Bill or Merula along. This choice will heavily influence most of the chapter. The main story won’t be affected much, but the rest of this chapter will differ significantly. It’s also worth noting that in order to pick Bill, you need to have his friendship at least at level nine, which shouldn’t be hard to achieve at this point.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Merula’s reaction will be quite interesting if you decide to pick her.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21 Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21 Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Depending on your house and the friend you bring along, Diego might show up to sneak you in.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Shortly after, you’ll get to talk with the Fat Friar and ask him about Peeves.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

He’ll be curious to know why you seek his aid. You have three response options, but all of those will lead to pretty much same outcome, so feel free to select whichever one you want.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

You’ll then get to talk to him and see what he has to say about the poltergeist. To do that, you need to earn at least one out of five stars within three hours to pass.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

There should be a couple of 5 cost actions here, so on average, you should be able to finish this with around 55 energy or so.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Sadly, you won’t get much information out of him, so you’ll have to ask elsewhere. Proceed to the Slytherin Common Room when you are ready.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

If you are not Slytherin and you took Bill along, Merula will appear to sneak you in. In any case, she won’t be too excited about getting you into her Common Room.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Shortly after, the friend you brought along will ask if you want to take the lead or if you want them to approach the Bloody Baron. The next following scenes will be quite different depending on this choice.

After getting his attention, you’ll be able to ask him some questions. To do that, you need to earn at least one out of five stars within three hours.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Completing this will require around 55-60 energy, depending on the actions you do.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Once you finish the task, you’ll realize that the Bloody Baron isn’t willing to share much information about Peeves.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Which is why you need to ask around some more. Proceed to the Gryffindor Common Room to question Nearly Headless Nick.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Sir Nicholas will be quite surprised to see the two of you.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

After explaining the situation to him, you’ll get to ask him some questions. Similar to the previous tasks, this one also requires you to obtain five stars within three hours with one star being needed to pass.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Like before, you’ll need 55-60 energy to fully complete this task.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

He’ll give you a piece of advice once you’re done.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

After finding out that you talked to some of the other ghosts, he’ll be curious to know whose advice was the most useful for you so far. You have three options to respond with. The outcome will be pretty much the same, so feel free to go with the one you prefer.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

The last House Ghost you have to visit is the Grey Lady. Proceed to the Ravenclaw Common Room when you are ready.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

If you aren’t a Ravenclaw, Badeea will show up to sneak you in.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

After a bit, you’ll get to choose if you or the friend you took along should talk to the Grey Lady. The following scene will be quite different depending on this choice.

You’ll then get to talk to her and see if she can tell you something interesting. Like before, you’ll need to earn five stars within three hours.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

There is a waiting period after this task, so you should fully complete this task as fast as possible in order to trigger it.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Once you are done, you’ll realize that none of the Ghosts were very helpful so far…

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21 Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Shortly after, you will come to the conclusion that Professor Binns can perhaps tell you more.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21 Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21 Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Before you can proceed, there is a waiting period of three hours.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Once you are able to continue, head to the History of Magic Classroom.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Merula will be curious to know why you asked both Bill and her to accompany you here. You have three response options. If you, by any chance, fancy her, it is highly recommended to pick the first option. Otherwise, you can go with any of the other two.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

After explaining the situation, the Professor will agree to tell you more about poltergeists.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

There are 5 cost actions available linked to Binns and Bill, so be sure to complete them whenever you get the chance.

Both of the Weasley brothers will be in the Prefects’ Bathroom, awaiting your arrival.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

After one hilarious conversation, Duncan will show up.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

You’ll explain the situation to him, but he’ll be very hesitant to lend you his aid. He’ll ask you to guess where Peeves is hiding, and if your answer is interesting, he might help you find him. You have three different options to choose from, but generally, each will lead to the same outcome, so feel free to pick the one you find the most appropriate.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

You’ll then get to talk to Duncan and see what he knows. To complete this task, you need to obtain five stars within eight hours. One star is required to pass.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

There is a 5 cost action tied to Duncan, so if you’re looking to save some energy, it is recommended to do that one as often as possible.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Once you finish the task, he will agree to help you and set up a meeting with Peeves.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Shortly after, the chapter will end. Hit the Collect button to claim your rewards.

Harry Potter Hogwarts Mystery Walkthrough Year 5 Chapter 21

Finally, after questioning all the ghosts, you found the one that was actually helpful. And all that’s left is to confront Peeves and ask him to give you the vault portrait. But will that go as smooth as you might expect? Or will he want something in return? Find out in the next chapter of this adventure!
