Chapter 15 – The Counter-Serum

Introduction

Hello everyone, welcome to our Walkthrough for Chapter Fifteen of Year Seven of Harry Potter Hogwarts Mystery. During the previous chapter, you informed Ben about your conversation with Rita, and he agreed that the best course of action would be to break into Madam Umbridge’s office.
You realized you needed a distraction to make sure she would leave the office, so you decided to pull a prank on her.

You met with Tulip at Zonko’s, and after considering all sorts of pranks, you settled upon tricking Madam Umbridge with a Dungbomb. After you arrived in her office, she offered you a cup of tea and asked you to tell her about your adventures. Luckily, you managed to set up the Dungbomb without her noticing it, and your plan worked as intended. Once Madam Umbridge left, you searched the office and found a document stating that the Ministry is planning a Wizengamot trial.

You informed Rita about it, and she said that you can find Zenith Xeep in Knockturn Alley. You went there with Ben and found Madam Xeep accompanied by the Dark Witch you saw near the end of your Sixth Year. Sadly, Ben was too reckless, and the Dark Witch got away. You confronted Zenith Xeep and demanded some answers, but unfortunately, she was unwilling to cooperate, so you had to duel her. After defeating her, she drank the entire bottle of memory-erasing potion and couldn’t remember anything, so you decided to report back to Mad-Eye Moody.

Walkthrough

Video guides are available on our YouTube channel. Use the button below.

But before that, you should take care of lessons and assignments. Proceed to Muggle Studies when you are ready. You will need to earn nine stars from Muggle Studies classes to unlock the Hair Spray lesson. Pick the class duration that suits you and hit Start to begin.

As usual, focus on bonus progress actions whenever they are available to save some energy.

Each mini-task you successfully complete will award you some Empathy points, so try your best to do them all.

Return to the classroom once you obtain enough stars to unlock the lesson. During the lesson, Professor Sikander will ask you a question about hair spray.

Once you’re done, proceed to the Ministry Office to start the assignment. Amos Diggory will greet you and say he has an assignment for you.

You’ll be eager to help, and Mr. Diggory will inform you about the assignment.

As it seems, you will need to help the Beast Division with a report. Mr. Diggory will ask you to research the fauna native to Britain and Ireland and make a report afterward. You will happily agree to help the Beast Division.

You will need to complete several tasks to finish the assignment. As always, you can feel free to do them in any order you prefer.

While doing these, you should select the task duration that matches the required number of stars.

Prioritize bonus progress actions if you want to save as much energy as possible.

Successfully completing each of the mini-tasks will grant you some extra attribute points.

Return to the Ministry Office once you complete all of the tasks. Amos Diggory will praise you for the job well done.

You’ll thank him and say that you’ve done a lot of research. Mr. Diggory will be amazed by your knowledge of the magical creatures in the Forbidden Forest, and you’ll humbly mention that Hagrid told you everything. He will be glad he chose you for the task, and then he’ll decide to prepare the final report for the Minister of Magic.

You will receive a reward for completing the assignment.

Now that you’re done with lessons and assignments, you can proceed to the Department of Magical Law Enforcement to report to Moody. Upon arriving, you will notice the speech bubbles above some of the characters. Tap on those if you are curious to see what they have to say. Once you greet Mad-Eye, he will say it is time to debrief.

You will wonder why Ben isn’t there. Moody will explain that he already talked to your friend, and he’ll then ask why you decided to disobey his order. You can choose to apologize to Mad-Eye or stand by your decision. If you want to get on his good side, it is recommended to apologize.

Either way, Moody will remind you that being at the Ministry of Magic is a privilege.

He’ll tell you to be more careful in the future and not put yourself in unnecessary danger. He’ll then ask you to tell him what happened during your confrontation with Zenith Xeep. Unfortunately, Ben was unable to tell him much since he was knocked unconscious by the Dark Witch. You’ll decide to tell him everything you saw.

Debriefing with Moody requires earning five stars within three hours. All five stars are needed to pass, so avoid starting this task if you are low on energy.

Be sure to slide the screen left and right to see all the available actions. There are bonus progress actions tied to a Ministry Witch and the statue. Focus on those if you want to save some energy.

You will tell Moody about the Dark Witch you saw in Knockturn Alley.

He’ll ask if you are worried that the Twycross you’ve been dealing with isn’t the real one. According to Mad-Eye, that hasn’t been the case. You’ll wonder why he is so sure about it, and he will explain that ever since the Metamorphmagus incident, he’s been monitoring the key figures.

He’ll also tell you he believes that the Dark Witch you encountered is a high-ranking member of ‘R’. You will say you had the feeling that Madam Xeep was afraid of her, and Mad-Eye will ask you to describe the Dark Witch. There are three options to reply with. This choice will be referenced later on.

Unfortunately, you won’t be able to tell him much. To make matters worse, the only person who could provide some answers drank the entire bottle of memory-erasing potion. You’ll ask Moody about Madam Xeep. He’ll tell you that she’s at St. Mungo’s, and the healers are trying their best to restore her memory. Unfortunately, the chances of recovering her memories are very low. Following that, you will decide to check if Professor Snape and Penny managed to finish the counter-serum.

You’ll need to wait three hours until the counter-serum is ready. Since you will likely be low on energy at this point, it is recommended to wait and let your energy recharge in the meantime.

Head to the Potions classroom once the waiting time is over. Penny will happily inform you that the counter-serum is almost ready.

You’ll be glad to hear that, and Professor Snape will tell you to contain your excitement.

You’ll apologize and ask if he managed to figure out the ingredients in Xeep’s Luscious Locks Solution. The professor will nod, and Penny will say that Wampus Cat tears were one of the ingredients. You’ll quickly figure out why a Wampus Cat was in Hogsmeade. You will learn that Wampus Cat tears are what’s causing people to rapidly lose their memory.

You’ll ask them some more questions about the potion. Sadly, you won’t get any answers, and Professor Snape will tell you to stop asking questions. He’ll task you with helping Penny finish the counter-serum. Finishing the counter-serum requires earning five stars within eight hours. All five stars are needed to pass.

There are bonus progress actions tied to Professor Snape and your character. Prioritize those if you want to save as much energy as possible.

After finishing the counter-serum, Penny will say she wants to add another ingredient, Professor Snape’s hair. The Potion Master won’t like the idea, and you will find it odd that Penny wants to add hair to the counter-serum. She’ll explain her reasoning.

You will then get to choose from three possible options. You can either encourage Snape to add some of his hair or ask Penny to do so. Alternatively, you can choose not to add any hair. This choice will be referenced later on, but it won’t significantly change the story, so feel free to go with the option you prefer.

In any case, the counter-serum will be ready for use. You’ll be happy knowing that the people affected by the memory-erasing potion can finally get their memories back. Professor Snape will explain that the counter-serum doesn’t restore memories but only counters the degenerative properties of the potion. Penny will apologize for not being able to do more, and you’ll tell her there’s no need to apologize. You will decide to head to Diagon Alley and help Madam Xeep’s victims.

Proceed to Ollivander’s when you are ready. Upon arriving, you will be able to interact with some of the characters and see what they have to say. Mr. Ollivander will be glad to see you again.

You’ll say that you’ve come to deliver the counter-serum, and he’ll tell you that his memory is still a bit fuzzy.

Shortly after, you’ll quickly decide to distribute the counter-serum to everyone. To do that, you’ll need to earn five stars within three hours. All five stars are needed to pass, so avoid starting this task if your energy bar is empty.

Be sure to slide the screen left and right to see all the available actions. There are bonus progress actions linked to Madam Villanelle, your character, and a vial of counter-serum. Prioritize those if you want to save some energy.

After you distribute the counter-serum, everyone will drink it.

You will ask Mr. Ollivander if he is feeling any different. He’ll smile and say that he feels absolutely marvelous. Your previous choice will take effect here.

You’ll be glad to hear that, and Ben will inform you that everyone else is feeling better as well. You will apologize to Mr. Ollivander for not being able to retrieve the stolen wand. Thankfully, he won’t hold it against you.

You’ll wonder why someone would want to steal one of his wands. Mr. Ollivander will explain that the stolen wand was very rare and powerful.

Ben will be curious to know why the wand was stolen. Unfortunately, you won’t have the answer to that question, but you will be determined to find out. You’ll decide to see if Corey might be able to help with the mystery.

Head to the Three Broomsticks once you are ready to continue. Upon arriving, you will notice the speech bubbles above some of the characters. Tap on those if you are curious to see what they have to say. You’ll thank Corey for agreeing to meet with you.

She’ll tell you there’s something she wants to talk to you about. Before that, she’ll let you ask your question. You’ll ask if she could tell you anything about Phoenix wand cores. You will tell her that you learned that those wands are very rare and powerful. Corey will wonder if your question has something to do with ‘R’.

You’ll nod and tell her that Ben and you were working on an assignment for the Department of Magical Accidents and Catastrophes. Apparently, Corey already heard about the incident involving Zenith Xeep. You’ll tell her that a Blackthorn wand with a phoenix feather core was stolen from Ollivander’s, and you will also mention the Dark Witch you encountered.

Corey will ask you to tell her what happened next. Following that, you’ll tell her about the moment the Dark Witch stared at you.

The choice that you’ve made while talking to Moody will take effect here.

Corey will be horrified after hearing that, and she’ll ask you to change the subject. You’ll agree and suggest discussing wands with phoenix feather cores. She’ll tell you that only skilled witches and wizards can use those wands. When you inquire if she knows any people who possess phoenix feather core wands, Corey will name a few.

Also, those wands can perform the greatest range of magic. You’ll assume that the wand was likely stolen for its power. Still, stealing the wand isn’t a way to win its favor. You will thank Corey for the information and ask if there’s anything she wants to talk about. She’ll say she wants to talk about Merula, and you’ll ask her to tell you what she managed to find out. Talking to Corey requires earning five stars within an hour. Three stars are needed to pass.

Be sure to slide the screen left and right to see all the available actions. There are bonus progress actions tied to Corey and your character, so focus on those if you want to save some energy.

You’ll learn that Corey intercepted a quill Merula left at the Whomping Willow, and you will ask if she untransfigured the quill. Corey will nod and say that it was indeed a note. She’ll then tell you about what the note said.

She’ll assume that Merula was involved in the Wampus Cat attack. There are two options for you to reply with. If you like Corey, it is recommended to pick the first option. If you like Merula, you should go with the second one.

In any case, you will praise Corey for finding the message. You’ll figure out that Merula is reconsidering working with ‘R’. This line will differ, based on your previous choice.

On top of that, it shows that the Most Powerful Witch at Hogwarts still cares about her friends.

Corey will recall you saying that you also have some news about Merula, and you’ll tell her about your previous talk with the Most Powerful Witch at Hogwarts. The following dialogue will differ based on the choice that you’ve made while talking to Merula.

Shortly after, Mad-Eye will show up and approach your table, and you’ll introduce Corey to him. Corey will find it hard to believe that she got the chance to meet the famous Auror.

She’ll tell you some things about the Moody family.

Mad-Eye will tell you that the Minister of Magic, Cornelius Fudge, wants to have a word with you.

You will need to wait four hours until the Minister is ready to see you. Since you will likely be low on energy, it is recommended to wait and let your energy recharge in the meantime.

Proceed to the Ministry All-Purpose Room once the waiting time is over. Upon arriving, you will be able to interact with some of the characters by tapping on the speech bubbles above them. The Minister of Magic will happily greet you.

You’ll politely tell him that you’re honored to help the Ministry, and he’ll say that you are welcome to come back to the Ministry in the future. He will then ask if you are considering a career at the Ministry of Magic. There are two options to reply with. If working at the Ministry is something you want, you should select the first option. If you are unsure about it, it is recommended to pick the second one.

You’ll politely ask the Minister what he wants to speak to you about. He’ll say that you probably heard about the upcoming Wizengamot Trial and admit that the Ministry isn’t sure how Rita Skeeter managed to obtain the information. He’ll also say they are looking into the matter. Luckily for you, Rita decided not to reveal her source.

The Minister will then tell you more about the Wizengamot trial. Learning about the trial requires earning five stars within three hours. Three stars are needed to pass.

Make sure to slide the screen left and right to see all the available actions. There are bonus progress actions tied to Mad-Eye and your character. Prioritize those if you want to save some energy.

You will learn that the person going on trial is none other than the white-robed wizard from Mahoutokoro.

You will be surprised to hear that. The Minister of Magic will say that Merula, Jacob, and you will be required to testify, and you’ll also learn that Jacob already agreed to testify at the trial.

The Minister will say that your testimony is essential to keeping the white-robed wizard locked up for good, and shortly after, he will leave to meet the Muggle Prime Minister. Mad-Eye will notice that you are upset, and you’ll remind him of what the white-robed wizard said before.

Moody will advise you not to be distracted by fear, and you’ll tell him you are worried that others may think you are aligned with ‘R’.

This will mark the end of Chapter 15 of Year 7. Hit the Collect button to claim your rewards. You will receive 350 Coins and 2000 Experience Points.

What will happen next? How will others react once they learn about the trial? Find out in the next chapter of Harry Potter Hogwarts Mystery!
