The Weird Sisters Part 4
Introduction
Hello everyone, welcome to Part 4 of our Walkthrough for The Weird Sisters Adventure of Harry Potter Hogwarts Mystery. In the previous part, you created a Sleeping Draught strong enough to incapacitate Filch.
Later on, you went to talk to one of your classmates regarding the promotion of the concert. Lastly, Myron asked for your help to create some pyrotechnics for the show. The first thing that came to mind was the Fire-Breathing Potion, so you made one for the upcoming performance.
Now, the only thing left is getting the proper instrument for you. Hit the GO button and proceed to the Transfiguration classroom to meet the band.

Walkthrough
[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.]
Basically, the band has a singer, a drummer, and a guitar player. So, you’ll be the one playing the bass.

Thankfully, the band knows a spell that can turn a cauldron into a bass guitar. Learning it requires you to earn five stars within three hours. Since all five stars are needed to pass, avoid starting this task if you are low on energy.

There are bonus progress actions tied to Myron and the cauldron. Focus on those whenever you get the chance if you want to save some energy.

Once you get all five stars, you’ll be tasked with casting the spell. Trace the path on the screen to do so.

The spell will work and it’ll turn the cauldron into a bass guitar. The only problem is that you don’t know how to play it.
Thankfully, there is a spell that could help you with that.

The Weird Sisters will tell you to meet them in the Charms classroom, so proceed there when you are ready to continue.
Upon arriving, you’ll learn there is a spell that could make the instrument play on its own, which will be handy since you don’t have much time before the show starts.
However, enchanting their instruments is not what the Weird Sisters are doing. Orsino will tell you that they practiced for years to get good at playing. Moments later, Myron will start teaching you how to cast a Music Spell on your guitar.

To learn this spell, you need to earn five stars within three hours. All five stars are required to pass. Because of this, make sure your energy bar isn’t empty when you start.

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

When you’re done, your character will cast the music spell and the guitar will start playing on its own.

Now that everything is ready, you can proceed to the Training Grounds to start the show.
Upon arriving, you’ll notice that the stage is set and the crowd is eager to see the performance. You can interact with some of them by tapping on their speech bubbles.
As it seems, your classmate did an awesome job gathering a large audience. The following few lines will differ, depending on the person you chose to promote the concert.

You’ll talk to Myron for a bit before drinking the Fire-Breathing Potion to impress the crowd and prepare them for what’s to come.

Afterward, Myron will cast the amplifying charm on your bass to make it play even louder.
Right after that, he’ll address the crowd before kicking things off.

Playing a concert is an eight-hour task requiring five stars to pass.

During this one, you can actually hear the music playing in the background, which will further add up to the atmosphere. You’ll notice that there are plenty of bonus progress actions here, mainly linked to the crowd and Myron, so it shouldn’t take you too long to finish the task.

Once the performance is done, Myron will thank everyone for coming and being such an amazing audience.

After that, he’ll ask you to meet him and the others in the Potions classroom. Go there when you are ready to continue.
When you get there, you’ll discuss the performance and Myron will decide to give you the Black Quill, as promised.

Orsino will say that the only thing that could top it off would be performing in the Great Hall. Perhaps, in several years, that could be the case, who knows?

Shortly after, you’ll need to cast Reparifarge on the Black Quill and see if it holds any clues to one of the vaults.

The spell will work and the quill will turn into a note.
Reading it will reveal some rather interesting information.


Now, that is something new. This is the first time you’ll hear anything about the Sunken Vault. And also the first time you’ll hear Kirley talking. He’ll point out that the person who wrote the note clearly visited a Cursed Vault before.
He’ll wonder if that person broke the curse. He will also be curious to know how the writer of the note survived.

Most importantly, Kirley will want to know who wrote the letter, and who was supposed to receive it. Also, he’ll be curious why the recipient transfigured the letter back into a quill, and leave it for you to find.

This will leave Myron, Orsino, and you completely speechless.
Kirley will admit that he enjoys a good mystery.

After that, Myron will give you a parting gift as a thank you for everything you’ve done for the band.

You will wholeheartedly thank him and say that you will always be a proud member of the Weird Sisters.

And with that, Part 4 of the Weird Sisters adventure will come to an end. Hit the Collect button to claim your rewards. You will receive 3 Chocolate Frogs and a special outfit.
You will earn the achievement for completing the adventure.

The outfit you received from Myron will be added to your wardrobe.

Wow, what an adventure! That was one performance Hogwarts won’t soon forget. The concert was so great and the audience was amazing! Everything a rock star could ever wish for. And the Black Quill message near the end was a cherry on top.
Could this revelation help you solve the mystery of the cursed vaults? There is only one way to find out – continuing the main story and jumping into the excitement of the curse-breaking adventures!
Thank you for reading.
