Hello everyone, welcome to our Walkthrough for Chapter Three of Year One of Harry Potter Hogwarts Mystery. In the previous Chapter, you arrived at Hogwarts School of Witchcraft and Wizardry and got sorted into a House. You checked your Common Room out and got familiar with your new home.

Afterward, you attended your first Charms class in which you learned the Wand-Lighting Charm – Lumos. Next, you had a Potions class with Professor Snape, where you learned to brew Cure for Boils. However, thanks to Merula Snyde’s sabotage, you got punished and lost ten House Points.

Now is the time to report to your Prefect and explain the situation. Tap on the GO button to proceed to your Common Room.

[Disclaimer: Walkthrough for this chapter has been updated in September 2021.]

On the way there, you will encounter another first-year student. His name is Ben Copper. You’ll find out that he is in Gryffindor house, and he’ll thank you for standing up to Merula.

After some talking, you’ll find out that he got bullied by Merula a lot because he is from a Muggle family. That is one of the reasons he is always afraid of things. When you’re done with the conversation, proceed to your Common Room.

You’ll meet your Prefect for the first time. You’ll have the chance to explain yourself and earn some attribute points in the process. Choose one of the options to respond with when your brother gets mentioned.

Your Prefect will show you a letter sent by Professor Snape. In the letter, he will say he came to the conclusion that your potion might have been tampered with. He’ll ask you to bring him a jar of Pickled Slugs from the Potions Storeroom if you want to restore the house points you lost.

Rowan will immediately offer to go with you, so you have the option to let your friend tag along. If you like Rowan, it is highly recommended to pick the first option.

Your Prefect will be delighted to hear that you have a way to restore the House Points and will suggest you get that Jar for Professor Snape immediately. So, hit that GO button and proceed to the Potions Storeroom.

If you decided to let Rowan join you, the two of you will meet up at the storeroom door. Something will seem odd since your friend won’t be sure if you are at the correct location.

In any case, upon entering, you be completely surrounded by darkness and will notice that the door behind you is locked. You’ll have to cast the Wand-Lighting Charm to illuminate your surroundings in order to see anything.

Trace the path on the screen to successfully cast Lumos.

Once you do that, your wand will shine some light around and you’ll realize that you definitely aren’t in a potions storeroom. You will notice a huge plant-like creature in the room. You’ll then hear Merula speaking from the other side of the door, and you’ll find out that it was all a trap set by her, and the creature in the room is the Devil’s Snare.

Since you have to get out, you’ll decide to repel the Devil’s Snare while waiting for the help to arrive.

So, the next task is to get back to your Common Room and report to your Prefect. After you explain the whole situation, your Prefect will suggest you change your outfit.

So, like in other classes, complete actions by tapping on various objects to fill up the Star Meter. Every time you earn a star, you will be able to choose one of three possible rewards. Those are mostly random, but you can get from 5 to 40 attribute points for a single attribute, you can get from 25 to 1000 coins, and in some rare cases, you’ll be offered energy, gems, or notebooks.

We strongly suggest you pick attribute points in most cases unless you’re offered something like 200 or 1000 coins, gems, or notebooks. When taking attributes, always select the option with the most points offered.

Rowan will then explain the basic rules. To win the game, you’ll need to distract your opponent. The way to accomplish this is to choose the correct option. This will fill the Diamond Meter. You need to get three Diamonds to win. Also, each of the options is tied to a certain attribute, and having that attribute at a high level will fill up more of the Diamond Meter.
