Hello everyone, are you excited for Chapter Twelve of Year Four of our Magical Journey Walkthrough for 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. In the meantime, you helped Tonks with her Herbology test. After that, you had some fun pranking Filch and she even helped you improve your dueling skills. Lastly, Penny and you successfully brewed the Beautification Potion. Everything was going according to plan, but just before you were 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.

For now, you can start things off with the lessons part of the chapter. Hit the GO button and proceed to the Charms Classroom.

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.

This one requires you to earn five stars within an hour with one being 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.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

On average, you’ll need to spend between 25 and 30 energy to get all the stars which should easily be doable with a single energy bar.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

Like with all the classes, try completing all of the mini-tasks to gain some additional attribute points.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

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 in two ways.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

It is recommended to accept his proposal since both options basically lead to the same outcome, so while you’re at it, you might as well earn some extra attribute points. Later on, you’ll be rewarded with some House Points if you chose this option. For the next task, you should proceed to the Great Hall to spy on Madam Rakepick.

Once you’re there, you’ll be able to interact with several characters and see what they have to say.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

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 should you two be talking about while eavesdropping on Madam Rakepick. You can select one out of three options.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

Since all of the options are awarding the same amount of attribute points and all lead to the same outcome, you can feel free to select the one you like the most.

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

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

Sadly, there aren’t any high-cost actions for this task, so you’ll likely need around 55-60 energy to complete it.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

After you finish, you’ll witness an interesting conversation between Madam Rosmerta and Madam Rakepick.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

Whenever you can, do the high-cost actions to optimize the energy usage.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

Shortly after you’re done, Madam Rakepick will notice that you’ve been spying on her. She’ll then ask you if you’re satisfied with what you’ve learned. You have three response options.

Harry Potter Hogwarts Mystery Walkthrough Year 4 Chapter 12

Each of the options will award you five attribute points, but there isn’t much of a difference in the outcome. Your next task is to report back to Professor Snape. However, there is a three-hour waiting period before you can continue.
