The Weird Sisters Part 3



Hello everyone, welcome to Part 3 of our Walkthrough for The Weird Sisters Adventure of Harry Potter Hogwarts Mystery. Last time, you assisted Myron with gathering the props for the upcoming performance. You also learned the true meaning of chaos and entropy by blasting the Artefact Room with him.

This attracted Peeves who decided to help you by distracting the Professors right before the show starts. You also got to witness and potentially even participate in the Weird Sisters bonding ritual. Lastly, you had the chance to tell the band you fancied one of your friends.

Now, you should head to the Artefact Room to meet Myron, so proceed there when you are ready.

[Disclaimer: This walkthrough will feature the gameplay from the perspective of a Year 3 student. Since the adventure is available for students of Year 2 and above, the star and attribute requirements for certain tasks might be different for you, depending on your current progress of the main story.]

Once you arrive, Myron will apologize for his previous behavior and he’ll promise to keep your romantic secrets safe.

The reason he invited you to the Artefact Room is fairly simple – he wants you to brew a Sleeping Draught strong enough to incapacitate Filch.

You’ll be unsure at first, but since he brought all the things necessary for that potion, you’ll decide to give it a try.

Brewing the potion is a three-hour task that requires you to earn five stars to pass. Because of this, you should avoid starting the task with an empty energy bar.

There is an action with bonus progress tied to Myron. Prioritizing it should save you a bit of energy.

When you finish the task, Myron will tell you that Orsino and Kirley are going to give the Sleeping Draught to Filch, so you don’t need to worry about that.

However, someone will need to promote the concert. After all, you’ll need every student at Hogwarts to know about the performance in order for it to be successful. The question is, who will you ask to promote the show?

You have three options to choose from. Each of them will be perfectly capable of promoting the concert. This choice will affect some parts of the adventure, but it won’t impact its story significantly, so feel free to pick whomever you deem the most appropriate for the task.

When you are ready, head to the Great Hall to meet the person you selected.

Upon arriving, you’ll be able to interact with certain characters. Simply tap on the speech bubbles above them to do so.

You’ll explain the situation to the classmate you chose and surprisingly, they won’t hesitate to help you.

The two of you will then start making fliers. Completing this task requires earning five stars within three hours. One star is needed to pass.

Sadly, there are no bonus progress actions here, so you won’t be able to save much energy.

Once you are done, you will thank your classmate for helping you.

Shortly after, Myron will ask you to meet him in the Potions classroom, so go there when you are ready.

When you arrive, Myron will tell you that Orsino and Kirley managed to take care of Filch, which is certainly good news.

However, they still need some pyrotechnics for the show and they thought it would be a good idea if you could brew the Fire-Breathing Potion for that purpose.

To complete this task, you need to obtain five stars within three hours. All of the stars are required to pass, so it might be a good idea to have full energy before you start.

There are actions with bonus progress tied to Myron and Orsino. Focus on those if you want to save some energy.

After you’re done with the brewing, you’ll try the potion to see if it works.
