Chapter 15

Hello everyone, welcome to our Walkthrough for Chapter Fifteen of Year Six of Harry Potter: Hogwarts Mystery. During the previous chapter, you got to spend some time with Cedric, and you helped Madam Pomfrey with tending to some patients. Later on, you went to brew some Pepperup potion for her. While you were brewing it, Professor Snape asked you to follow him to the Hospital Wing. Once you got there, you found out that Madam Pomfrey got petrified. Professor Dumbledore decided to make an announcement, but before that, you should finish the lessons. Head to the History of Magic classroom when you are ready.

Unlocking Wendelin the Weird lesson requires earning nine stars from History of Magic classes. Select the class duration you prefer and hit Start to begin.

As always, prioritize 5-cost actions to save some energy.

Also, try your best to complete as many of the mini-tasks as possible. This will earn you some additional Knowledge points.

Upon earning enough stars, head back to the classroom to attend the lesson.

Completing Wendelin the Weird lesson requires earning five stars within eight hours. All five stars are needed to pass.

For the most part, this is very similar to regular 8-hour lessons.

The major difference includes mini-tasks. Below are questions and the answers to most of those.

For the second lesson, proceed to the Divination classroom when you are ready.

To unlock Numerology lesson, you need to acquire a total of nine stars from Divination classes.

Like before, prioritize 5-cost actions if you are looking to save some energy.

As for the mini-tasks, most of these will require you to keep your ‘focus’ up in order to successfully complete them.

Head back to the classroom once you obtain enough stars.

To complete Numerology lesson, you need to earn five stars within eight hours.

Other than a couple of mini-tasks, this lesson is fairly similar to the previous classes.

Now that the lessons are out of the way, you can proceed to the Great Hall to hear Dumbledore’s announcement.

Upon arriving, you’ll be able to interact with some of your friends before continuing.

You will inform your friends that the rumors about Madam Pomfrey are true.

Needless to say, most of them will be shocked to hear that.

Moments later, the Headmaster will start his announcement.

He’ll tell everyone about the recent events.

He’ll also say that there are some new rules everyone needs to follow.

Learning these new rules requires obtaining five stars within eight hours. Only one star is needed to pass.

Your character, Dumbledore, and Merula all have 5-cost actions linked to them. Prioritize those to save some energy.

When you are done with the task, the Headmaster will say a few closing words.

He’ll also remind the students to stay close to the castle at all times.

Some of your friends will be surprised by this announcement.

Some others will find new opportunities opening up for them.

Tonks will ask for your opinion on the matter. There are three options to respond with. None of these will have any significant impact on the story, so feel free to pick whichever one you prefer.

In any case, you will decide to attend Bill’s Defence Against the Dark Arts session.

You’ll have to wait three hours until Bill arrives. Since this is exactly the time it takes for your energy to fully regenerate, it is recommended to simply wait until this timer runs out.

Once you’re able to continue, proceed to the Defence Against the Dark Arts classroom to attend Bill’s lesson.

As you arrive, you’ll notice the speech bubbles above some of your friends.

Bill will announce that today’s lesson will involve reviewing the Sea Urchin Jinx.

Practicing the Sea Urchin Jinx requires earning five stars within an hour. Three stars are needed to pass.

Both Ismelda and Rowan have 5-cost actions tied to them. Focus on these if you’re looking to save some energy.

When you are done, you’ll be tasked with casting the Sea Urchin Charm on Ismelda.

Bill will praise your performance.

Ismelda, on the other hand, will ask you to remove the effects of the spell from her.

Trace the wand movement on the screen to case Finite Incantatem.

Bill will thank everyone before calling it a night.

However, he will ask you and the friends that were with you in the Buried Vault to stay for a bit longer.

Rowan and either Penny or Charlie (the one you didn’t take with you to the Buried Vault) will also decide to stay.

Still, Bill will not want to get them involved, which will leave them a bit disappointed.

Next, Bill will explain his theory to the rest of you.

You will tell him about the time you were eavesdropping on Madam Pince and Professor Binns.

He’ll suggest doing some research in order to figure out where the final vault is.

Merula will agree to this under one condition.

Since you’ll just do some research, it might be better to split up.

You’ll decide to go to the Library and see if you can find anything.

There is one hour of waiting time before you can proceed. Once again, simply wait until this timer expires and let your energy replenish in the meantime.

After the waiting time is over, head to the Library to research the vault’s location.

Upon arriving, you’ll be able to interact with some of your friends before continuing.

You will thank Cedric for being kind enough to help you with the research.

As it appears, he is still very shaken up by what happened.

Also, he is afraid he might end up petrified as well. There are two options to respond with. None of these will affect the story in any significant way, but Cedric will react better if you pick the first option.

You’ll suggest researching possible locations of the final vault.

To do that, you need to earn five stars within one hour. Three stars are needed to pass.

Both Cedric and your character have 5-cost actions tied to them. Prioritize these if you want to save some energy.

Once you’re done, you will sum up your findings.

In any case, you’ll decide to investigate the Black Lake and see if you can find anything there.

Cedric will wish you good luck before leaving the Library.

As it appears, Beatrice was eavesdropping on your conversation, and she wants to go with you.

Once again, there is a waiting period of three hours before you can continue. Like before, it is recommended to wait until this timer runs out and let your energy regenerate in the meanwhile.

When you are able to continue, proceed to the Black Lake to search the Lakeshore. This will unlock the Black Lake as another location you can visit.

Since this is the first time you’re visiting this location, use the opportunity to enjoy the view.

Thanks to your Invisibility Cloak, the two of you managed to sneak out.

Beatrice will ask if you’re planning on telling Penny she snuck out with you. This choice will likely be referenced in the future, but won’t have any huge impact on the story. If you like Penny, it is recommended to pick the first choice, otherwise, feel free to go with either one.

Soon after, you’ll start looking for clues. This requires earning five stars within three hours. One star is needed to pass.

The only 5-cost action here is linked to Beatrice. Focus on her actions if you’re looking to save some energy.

Sadly, even after searching for nearly three hours, you won’t be able to find any clues.

However, just as you were about to leave, you’ll notice a wizard in white robes.

Before you get any chance to react, he’ll blast you with the Knockback Jinx.

Beatrice will rush to see if you’re all right.

Once you stand up, you’ll notice that the wizard is nowhere to be seen, and you’ll decide to quickly head back to the castle.

This will mark the end of Year 6 Chapter 15. Hit the Collect button to claim your rewards.

What will happen when you return to Hogwarts? How will your friends react once you tell them about the attack? And will Dumbledore find out you broke the rules again? Find out in the next chapter of Harry Potter Hogwarts Mystery.
Thank you for reading.
