Introduction

Hello everyone, welcome to our Walkthrough for the Billywig Blunder Side Quest of Harry Potter Hogwarts Mystery. This side quest is available for students of Year 5 and above, and it should unlock after reaching Chapter 20 of Year 5.

Once you start it, Hagrid will ask you to meet him in his garden, so go there when you’re ready.

Summary

Walkthrough

When you arrive, you’ll notice Fang floating in the air. Sadly, Hagrid won’t be able to get him down.

Needless to say, you’ll be surprised to see a dog floating. Hagrid will decide to tell you what happened as long as you help him get Fang down.

To learn what happened, you need to earn five stars within one hour. Three stars are required to pass.

There is a bonus progress action tied to the broken jar. Prioritize it to save a bit of energy.

Apparently, Hagrid was transporting a swarm of Billywigs rescued by the Ministry from the black market. Unfortunately, he dropped the jar and the creatures flew away. Hagrid will tell you some things about Billywigs.

You’ll quickly realize Fang was stung by one of the escaped Billywigs. Hagrid will say he’s afraid Fang might be allergic because he’s been floating half the day now.

And if that is the case, his floating could become permanent. You’ll decide to get Fang down.

There are three spells you can use to do so. The correct spell for this situation is ‘Descendo’.

Trace the wand movement to cast Descendo.

The spell will work and Fang will safely land on the ground.

Hagrid will suggest asking Professor Snape for help with the antidote. Unfortunately, the five escaped Billywigs are still on the loose.

You’ll tell Hagrid to look for the missing creatures. In the meantime, you’ll talk to Professor Snape about the antidote.

Before you leave, Hagrid will advise you to take another Billywig with you. According to him, those creatures can sense one another.

The following lines will differ, depending on whether or not you’ve adopted a Billywig.

Next, you’ll need to unlock Billywig.

To do that, you will need 30 Red, 35 Blue, and 25 Yellow Notebooks. On top of that, your Magizoology level needs to be 5 or higher. Luckily, this side quest is not time-limited, so you can take as long as you need to complete this task.

When you are done, go to the Potions classroom to talk to Professor Snape. You’ll find Snape brewing a potion. Unfortunately, he’ll be too busy to help you.

However, once you tell him you need an antidote for Billywig stings, he’ll turn his attention to you.

You’ll notice that Snape is not behaving like his usual self.

He’ll simply say that he is fine before asking you to tell him everything.

Talking to Snape is your next task. You need to earn five stars within three hours to complete it. Three stars are required to pass.

There are bonus progress actions tied to your character and the cauldron. Focus on those actions to save energy.

You’ll tell Professor Snape you need to make an antidote for Billywig stings as soon as possible.

Interestingly enough, he’ll agree to help you. You’ll realize that something is wrong with Professor Snape. It won’t take long for you to figure out why he’s acting like that.

Before getting started on brewing the antidote, Snape will ask you not to tell anyone he’s been stung by a Billywig. There are two options to reply with. If you don’t want to risk losing house points later, it is recommended to pick the first option.

Suddenly, your Billywig will fly away.

You’ll quickly figure out there’s another Billywig nearby. You will decide to follow the creature and catch the other Billywig before anyone else gets stung. Go to the training grounds when you are ready to continue.

When you arrive, you’ll spot some of your friends floating. You’ll realize that all of them were stung by a Billywig. You will take out your wand and cast Descendo.

The spell will work and your friends will safely land on the ground.

Penny will thank you for helping them and she’ll explain what happened.

Shortly after, you’ll tell your friends there’s another Billywig nearby. Barnaby will ask if anyone else got stung by a Billywig. If you don’t want to risk losing any house points, it is recommended to pick the first option.

Moments later, you’ll spot the Billywig that stung your friends.

Penny will tell you to get on a broom and catch the creature. If your character is a Seeker, you’ll get an additional line of dialogue.

Catching the Billywig requires earning five stars within eight hours. All five stars are needed to pass.

There are actions with bonus progress tied to Jae and your character. Prioritize those actions to save energy.

Luckily, you’ll manage to catch the Billywig.

You’ll decide to go back to Professor Snape and start brewing the antidote. Suddenly, you’ll realize that your Billywig is missing. Ismelda will tell you she saw Jae snatching the creature while you were on your broom.

You’ll recall what Hagrid said, that Billywigs catch quite a price on the black market. You will be sure that Jae knows this. Luckily, you know where Jae is headed next.

Go to Knockturn Alley when you are ready. Once you arrive, you’ll spot Jae showing your Billywig to a Dark Wizard.

You’ll quickly tell him not to sell the creature.

Apparently, Jae had no idea the Billywig is yours. He’ll ask if you believe him. There are two options to reply with. If you like Jae, it is highly recommended to pick the first option.

Thankfully, he’ll call off the deal and return the creature to you.

The Dark Wizard won’t be happy to hear that.

Unfortunately, he won’t be willing to let you go without a fight. The task window will display the recommended attribute levels and the cost of the duel.

The recommended attribute levels will be fairly similar to your attribute levels, which will make this duel quite challenging. One way to approach it is to go Defensive on the first turn and use the Incarcerous spell. This spell will often stun your opponent for two turns. If you get the stun effect, simply go Aggressive or Sneaky after that and use Depulso or Flipendo.

However, there is a chance you won’t get the stun effect. If that happens two turns in a row, you will most likely end up losing the duel. However, with a bit of luck, you should be able to win.

In the end, the Dark Wizard will walk away. Now that you have the Billywig back, you can go and brew the antidote.

You’ll need to reach level 4 trust with Billywig before you can continue. Since this side quest is not time-limited, feel free to take as long as you need to complete this task.

When you are done, go to the Potions classroom to brew the antidote. Once there, you’ll tell Snape you caught the Billywig that stung him. While you were doing that, he gathered everything needed to brew the antidote.

He’ll ask if you told anyone about his situation. There are two options to reply with. If you kept his secret, be sure to pick the first option.

Shortly after, you will start brewing the antidote. You need to earn five stars within three hours to complete this task. All five stars are required to pass.

There are bonus progress actions tied to Professor Snape and your character. Focus on those actions to save energy.

Professor Snape will praise your potion-making skills, in his own way.

He’ll then drink the antidote.

Luckily, the antidote will work, and Snape will return to normal. If you promised to keep his secret and didn’t tell anyone about it, you will receive five house points. However, if you broke your promise, you will lose ten house points.

You’ll decide to go back to Hagrid. You will need to reach max level Trust with the Billywig before you can continue. This might take a while, but luckily, there is no time limit to this side quest, so feel free to take as long as you need to complete this task.

Go to Hagrid’s hut when you are done. You’ll tell Hagrid you’ve brought the antidote for Billywig stings. By the looks of it, you’ll need to quickly administer the antidote to Fang.

You need to earn five stars within three hours to complete this task. All five stars are required to pass.

Make sure to slide the screen left and right to see all the available actions. There are bonus progress actions tied to your character and Fang. Prioritize those actions to save energy.

Thankfully, Hagrid will manage to grab Fang and give him the antidote.

Luckily, it will work. You’ll tell Hagrid you managed to catch one of the escaped Billywigs. He will say that he was able to catch two of them. In other words, there are two Billywigs still missing.

According to Hagrid, it is highly unlikely you’ll find the two missing creatures. There are two options to reply with. If you want to stay positive, it is recommended to pick the first option.

Shortly after, your Billywig will start buzzing. Could it be there is another Billywig nearby?

You’ll quickly decide to follow it. Go to the Desert Dunes area of Magical Creatures Reserve when you are ready to continue. When you arrive, you’ll spot Jae floating in the air. He’ll ask you to get him down.

The choice you made while talking to Jae in Knockturn Alley will take effect here.

Hagrid will also voice his opinion.

You’ll ask Jae to explain himself before you bring him down. You need to earn five stars within eight hours to complete this task. All five stars are required to pass.

There are bonus progress actions tied to your character and the Billywig. Prioritize those actions to save energy.

Jae will admit he had the other two Billywigs when you met him in Knockturn Alley.

The choice you made while talking to Jae earlier will take effect here.

As it appears, Jae was stung while trying to return the escaped Billywigs. He’ll apologize to you and ask for your forgiveness. There are two options to choose from. If you like Jae, it is highly recommended to pick the first option.

You will take out your wand and cast Descendo to bring Jae down.

He’ll thank you for helping him. According to Hagrid, all of the escaped Billywigs have been caught.

The creatures will happily buzz together.

This will conclude the Billywig Blunder side quest. Hit the Collect button to claim your rewards. You will receive 500 Experience Points and 200 Friendship Experience for Hagrid.
