Chapter 17
Harry Potter Hogwarts Mystery
Hello everyone, welcome to our Walkthrough for Chapter Seventeen of Year Six of Harry Potter: Hogwarts Mystery. During the previous chapter, Chiara healed your wounds. Later on, you found out that Dumbledore already knows about your trip to the lakeshore. This earned you detention. Both you and Beatrice went to the Kitchens, and after serving detention, you met with Talbott at the Owlery. After searching it, you found a message written in Japanese. You then went to the Library to translate it, and you learned that there are white quills hidden at the lakeshore. You decided to go there again, and Talbott was determined to accompany you. However, before going there, you should take care of the lessons. Head to the Charms classroom for the first one.

To unlock Gouging Spell lesson, you need to earn nine stars from Charms classes. As always, pick the class duration that suits you and hit Start to begin.

Prioritize 5-cost actions to save some energy.

Try to complete all of the mini-tasks to earn some extra Empathy points.

Upon unlocking the lesson, go back to the classroom to attend it.

Learning Defodio requires obtaining five stars within eight hours. All five stars are needed to pass.

Some of the mini-tasks are specific to this lesson.

Upon earning the fifth star, you will be tasked with casting the spell.

For the second lesson, proceed to Care of Magical Creatures.

Unlocking Moke lesson requires earning nine stars from Care of Magical Creatures classes.

Like before, focus on 5-cost actions if you want to save a bit of energy.

Completing mini-tasks successfully will earn you some bonus Courage points.

Head back to Care of Magical Creatures when you earn enough stars.

Completing Moke lesson requires earning five stars within eight hours. As with most other lessons, focusing on 5-cost actions will save you some energy.

Some of the mini-tasks are unique to this lesson, so try your best to complete them.

Upon earning the fifth star, you’ll be tasked with feeding the Moke.

Now that you’re done with the lessons, proceed to the lakeshore to look for the white quills.

If what was written in the letter is true, you might be able to find something here.

Talbott will remind you of the choice you’ve made while you were at the Library.



If you completed Become an Animagus adventure, you’ll suggest searching the place in your Animagus forms.

Doing so requires earning five stars within three hours. One star is needed to pass.

There are 5-cost actions linked to your character and a wooden log. Prioritize these to save some energy.

When you are done, you will find a white quill.

Could this be another message?

There is only one way to find out. Trace the wand movement to cast Reparifarge.

The spell will work and the quill will turn into a note.

Reading it will unveil some shocking information.



This looks like a serious issue. You’ll decide to inform the Headmaster immediately.


Soon after, the Headmaster will decide to address the students. Proceed to the Great Hall when you are ready.

Upon arriving, you will be able to interact with some of your classmates before continuing.

Apparently, your friends are well-aware of the recent events.


You’ll then get to discuss Dementors with your friends. To do that, you need to acquire five stars within an hour. Only one star is needed to pass.

There are 5-cost actions tied to Merula and your character. Prioritize those to save a bit of energy.

Liz will genuinely seem very worried about this.


Ben, on the other hand, won’t be too concerned about Dementors.

If you completed Unleash Your Patronus adventure, you’re in for some additional lines of dialogue.



Thankfully, reporting everything to the Headmaster got you out of detention.


This will grab Ben’s attention, so you’ll tell him and others what happened.


Upon hearing that, Ben will be even more determined to be your protector.

Liz, however, will doubt his intentions, which will get Ben agitated.


You will have two options to react to this. If you like Ben, it is recommended to go with the first one. Otherwise, you can feel free to pick either one.

Moments later, Dumbledore will start addressing the students.



As it appears, the Ministry will also be sending Aurors to help with the situation.


You’ll then receive an owl from Mad-Eye Moody, saying he will be arriving at Hogwarts in about three hours. Since your energy bar is likely empty, it is recommended to simply wait a while and let your energy regenerate in the meanwhile.

Once the waiting time is over, proceed to the Artefact Room to meet with him.

It looks like he wants to talk to you about Jacob.


You will tell him that you haven’t seen your brother recently.

According to Mad-Eye Moody, Jacob was at the lakeshore during the time of the attack.

You’ll then get to talk to him about it. This requires earning five stars within eight hours. All five stars are needed to pass.

Both Mad-Eye Moody and your character have 5-cost actions linked to them, which should save you some energy.

As it turns out, Jacob was the one who drove off the Azkaban escapee.


It looks like Jacob was focused on protecting you lately. You have 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.

Sadly, Mad-Eye Moody doesn’t know where Jacob currently is, so you’ll decide to check his room and see if he’s there by any chance.


There is a waiting period of four hours before you can proceed. Like before, simply wait until this timer expires and let your energy replenish in the meantime.

Head to Jacob’s room once the waiting time is over.

Once you arrive, you will tell Ben that your brother was the one who drove off the Dark wizard.


Perhaps he left something for you in his room?

It’s definitely a good idea to look around.

Searching the room requires earning five stars within three hours. Three stars are needed to pass.

There are 5-cost actions tied to the basket and the board. Prioritize these if you want to save some energy.

When you are done, you will notice a black quill on the table.


After discussing it for a bit, Ben will ask if you believe the threats from these quills. There are two options to reply with, but these won’t have any big impact on the story, so feel free to pick either option.

Ben will then open up to you.




He’ll advise you to untransfigure the black quill.


Trace the wand movement to cast Reparifarge.

The spell will work, and the quill will turn into a note.

Ben will be curious if this means your brother is working for ‘R’. There are two response options. If you care about Jacob, it is highly recommended to pick the second option.

In any case, it looks like your next destination is the Forest Grove.


This will conclude Chapter 17 of Year 6. Hit the Collect button to claim your rewards.

Will you be able to get past the Dementors? And what will happen once you get to Forest Grove? Find out in the next chapter of Harry Potter Hogwarts Mystery.
Thank you for reading.
