Chapter 12 – Working with Snape

ADVERTISEMENT

Introduction

Hello everyone, welcome to our Walkthrough for Chapter Twelve of Year Four of Harry Potter Hogwarts Mystery. In the previous chapter, you met Penny and made the list of all the ingredients necessary for the creation of the Beautification Potion. You then went on and gathered everything needed.

After that, Penny and you successfully brewed the Beautification Potion. Everything was going according to plan, but just as you were about to fly into the Forbidden Forest, Professor Snape saw you in the Courtyard and he broke the broom that you borrowed from one of your classmates earlier on.

This might make things a bit more difficult, so you’ll have to find a way to repair the broom in order to proceed with the plan.

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

Once you begin the chapter, you’ll be met with a waiting period of three hours, so you can start things off with the lessons. Hit the GO button and proceed to the Charms classroom.

year 4 chapter 12 1020

To unlock the Diffindo lesson, you need to earn nine stars from Charms classes. As usual, there are several ways of doing this, so pick the combination of classes that suits your playstyle the most.

year 4 chapter 12 1030

As for the classes, follow the usual pattern – tap on the glowing objects to complete actions. Each of those will fill up the star meter and you’ll eventually earn stars. Prioritize doing actions with bonus progress to save energy.

Every time you earn a star, you’ll be given a mini-task. Complete it and you’ll be awarded ten Empathy Points.

year 4 chapter 12 1050

When you are done, hit the Collect button to continue. Once you unlock the lesson, head back to the classroom to attend it.

Learning Diffindo is a three-hour lesson with a passing requirement of five stars. Because of this, it is somewhat recommended to have full energy before starting.

year 4 chapter 12 1080

You can follow the same steps you did in the classes you took while unlocking the lesson and you’ll finish it without a problem.

As soon as you obtain all five stars, you’ll be tasked with casting the spell. Trace the wand movement on the screen to cast the Severing Charm.

year 4 chapter 12 1110

Hit the Collect button to claim your rewards and continue.

Congratulations! You’ve just learned a powerful spell that you can use in duels. It is usable in Sneaky Stance and it causes some initial damage, which can be increased by having high Knowledge Attribute. It also has a chance to cause the opponent to bleed for several turns, taking damage each turn.

year 4 chapter 12 1130

For the second lesson of the chapter, proceed to the Transfiguration classroom.

Unlocking Serpensortia lesson requires obtaining nine stars from Transfiguration classes. Like before, pick the combination of classes that suits you best and hit the Start button to begin.

year 4 chapter 12 1150

While doing these classes, try to put the priority on bonus progress actions to save some energy.

Completing the mini-tasks is highly recommended to maximize the number of attribute points gained.

year 4 chapter 12 1170

When you are done, hit the Collect button to claim your rewards and continue. Once you unlock the lesson, head back to the classroom to attend it.

Learning Serpensortia requires you to earn five stars within three hours. Since all five stars are needed to pass, having full energy prior to starting is highly recommended.

year 4 chapter 12 1200

Approach this lesson in a similar manner to the classes you took earlier and you’ll be done in no time.

When you obtain the fifth star, you’ll need to cast the spell. Trace the wand movement on the screen to cast Serpensortia.

year 4 chapter 12 1230

Hit the Collect button to claim your rewards and continue. You can get an additional reward in the Transfiguration section of your Hogwarts Record.

year 4 chapter 12 1250

Now that both of the lessons have been dealt with, you can continue the story. Hit the GO button and proceed to the Potions Classroom.

Once you arrive, you’ll notice that some of the students have speech bubbles above them. Tap on those if you want to see what they have to say.

You will apologize to Professor Snape for being in the Clocktower Courtyard, and you’ll ask if he will return the broom he broke.

Snape will agree to return it to you, and he will explain that he took the broom from you to trick anyone watching that the two of you are at odds. You will be slightly confused to hear that because the courtyard was empty.

After that, Snape will tell you that Rakepick has been monitoring you ever since she came to Hogwarts. However, you will have to wait until the class is over to discuss the matter further.

year 4 chapter 12 1280

This class requires you to earn five stars within an hour. One star is needed to pass. Since it behaves like a regular Potions class, you’ll be able to gain rewards after earning each star. Because of this, it is highly recommended to have full energy before starting.

year 4 chapter 12 1300

You should easily be able to fully complete this task with a single energy bar. Like with all the classes, try completing all of the mini-tasks to gain some additional attribute points.

Once the class is over, Snape will explain his theory to you. He believes that Rakepick wants to seize control of Hogwarts and he needs your help to investigate her. You can respond to that in two ways. It is highly recommended to accept his request since both options basically lead to the same outcome, and if you pick the first one, you’ll be rewarded with some House Points later on.

year 4 chapter 12 1340

For the next task, you should proceed to the Great Hall to spy on Madam Rakepick. Once you get there, you’ll be able to interact with several characters and see what they have to say.

After that, you’ll join Ben at the table and explain the situation to him. He’ll agree to help you, but he will want to know what the two of you should be talking about while eavesdropping on Madam Rakepick.

You can select one of three options. Since all of the options are awarding the same number of attribute points and all lead to the same outcome, you can feel free to select the one you like the most. Some of those lead to very funny lines of dialogue, so keep that in mind when making this choice.

year 4 chapter 12 1370

Hanging out with Ben requires you to earn at least one out of five stars within three hours.

year 4 chapter 12 1380

Do this just like any other story task and you shouldn’t have much trouble with it.

When you finish the task, you’ll hear a pretty interesting conversation between Madam Rakepick and Filch. Filch will accuse Madam Rakepick that she stole the key from him earlier and that she hasn’t changed since she was a student. Madam Rakepick, avoiding Filch’s accusations, will interrogate him about where he got this key in the first place.

During the interrogation, Madam Rakepick will be very cruel to Filch, even calling him a Squib at one point. Filch will inform her that someone left a mysterious package in his office and inside it were three Black Quills and that key.

year 4 chapter 12 1400

You will need to wait three hours before you can continue. Since you will likely be low on energy at this point, it is recommended to wait and let your energy recharge in the meantime. When you are able to proceed, head to the Three Broomsticks to meet Hagrid.

Upon arriving, you’ll notice that some of the characters have something to tell you. Tap on their speech bubbles to see what they have to say.

Afterward, you’ll explain the situation to Hagrid and tell him the reason you’ve come to the Three Broomsticks.

year 4 chapter 12 1440

He’ll agree to hang out with you while you are spying on Rakepick. This is a three-hour task requiring one out of five stars to pass.

year 4 chapter 12 1450

Sadly, there aren’t any bonus progress actions available during this task, so you won’t be able to save much energy.

After you are done, you’ll witness an interesting conversation between Madam Rosmerta and Madam Rakepick. Madam Rakepick will try to interrogate Madam Rosmerta about Jacob’s Black Quill and a Map of Hogwarts.

year 4 chapter 12 1470

When Madam Rosmerta avoids answering her questions, Rakepick will try to threaten her, just like she did with Filch. However, that won’t work and Madam Rosmerta won’t give her any information.

You’ll have to wait three hours before being able to proceed to the next task. Once you’re able to continue, head to the Hospital Wing to spy on Madam Rakepick.

After talking to Madam Pomfrey, you’ll receive the next task. 

year 4 chapter 12 1500

You will need to spy on Madam Rakepick while tending to patients. To complete this task, you need to earn five stars within three hours. One star is needed to pass.

year 4 chapter 12 1510

There are bonus progress actions tied to your character, one of the patients, and the medicine cabinet. Prioritize those actions whenever they are available to save some energy.

year 4 chapter 12 1520

Madam Pomfrey will explain that students under the curse need more time to awake the longer the curse is active, and soon, cursed students won’t be able to wake up at all. Madam Rakepick will not be very interested in those details but will be more into why the curse returned.

Madam Rakepick will notice that you’ve been spying on her. She’ll ask if you’re satisfied with what you’ve learned. You have three response options. Each of the options will award you five attribute points, but there isn’t much of a difference in the outcome.

year 4 chapter 12 1530

Your next task is to report back to Professor Snape. However, there is a three-hour waiting period before you can continue. Once the waiting time is over, hit the GO button and proceed to the Potions classroom.

When you arrive, you’ll be able to interact with some of your classmates and see what they have to say.

Once again, you’ll have to wait until the class is over before you can talk to the Professor.

year 4 chapter 12 1570

This class lasts three hours and during that time you need to obtain at least one star in order to pass. There are a total of five stars available, each one with a reward and a mini-task.

year 4 chapter 12 1580

Do this just like any other Potions class and you shouldn’t encounter any problems.

After dismissing the class, Professor Snape will warn you never to mention anything related to Rakepick around other students. According to him, at least one of the Slytherin students is working for her.

year 4 chapter 12 1610

If you agreed to help Snape earlier on, you’ll be awarded twenty House Points. He’ll also give you a bottle of Garrotting Gas. It could save your life in some dangerous situations.

Shortly after, Chapter 12 of Year 4 will conclude. Hit the Collect button to claim your rewards. You will receive 250 Coins and 1800 Experience points.

This was an interesting turn of events. Apparently, Madam Rakepick has been watching you all the time. You should definitely be cautious around her. At least, you got the broom back and now you can proceed with the plan. But will it work? Will the Beautification Potion have an effect on the Red Cap? Find out in the next chapter of Harry Potter Hogwarts Mystery!

Thank you for reading and see you soon in the Wizarding World.
