The Halloween Feast Part 4
Introduction
Hello everyone, welcome to Part 4 of our Walkthrough for The Halloween Feast Adventure of Harry Potter Hogwarts Mystery. In the previous part, you learned that Chiara is a werewolf. She was bitten when she was just a little girl and she managed to keep her condition in check by using the Wolfsbane Potion.
However, she recently ran out of the ingredients for it, so she asked you to help her gather the missing ingredients. With the help of Rowan, you got some Aconite from the Potions Classroom. You also managed to convince Penny to help you brew this potion.
Once you start this part, there will be a waiting period of five hours before you can proceed with the next part of the story. Since you will likely be low on energy at this point, it is recommended to wait, and let your energy recharge in the meantime. However, if your remaining time on the adventure is less than 16 hours, you might want to consider spending some gems or time toffees to speed things up.

Walkthrough
Disclaimer: This walkthrough will feature the gameplay from the perspective of a Year 1 student. Since the adventure is available for students of Year 1 and above, the star and attribute requirements for certain tasks might be different for you, depending on your current progress of the main story.
Head to the Artefact Room once the waiting time is over. Penny will make it clear that she doesn’t wish to do anything with werewolves. Chiara will be puzzled that Penny doesn’t know her secret yet and she will reveal to her that she’s a werewolf.
Penny will be very surprised once she finds out that Chiara is a werewolf. Chiara will mention that she was bitten when she was a little girl. She doesn’t wish to hurt anybody, which is why she needs Wolfsbane Potion to stay in control after the transformation. She also wants to stop Greyback.

Nevertheless, Penny will agree to help you brew the potion. This task requires you to earn five stars within three hours. All five stars are needed to pass, so avoid starting this task if you are low on energy.

There is a bonus progress action tied to Chiara, so focus on her actions if you want to save a bit of energy.

When you are done, Chiara will place her trust in Penny and she’ll immediately drink the potion.
Sadly, there’s no way to know if the potion worked until the next full moon. This will frighten Chiara and she’ll ask you to do whatever it takes to stop her from hurting someone else in case she loses control.
You have three response options. If you like Chiara, it is recommended to pick the second or the third option.

For the next task, you need to check in with Cecil Lee. Hit the GO button and proceed to the Clocktower Courtyard once you’re ready.
Since there is a high possibility that Greyback will attack again soon, Cecil will decide to teach you a spell that is useful when dealing with werewolves – the Homorphus Charm.

Learning this spell is a three-hour task that requires you to earn five stars in order to pass. Because of that, it is not recommended to start this task with an empty energy bar.

There are only two objects you can tap on for this task – Cecil and your character. There is a bonus progress action tied to Cecil, so prioritizing his actions should save you a bit of energy.

Once you are done, Cecil will ask you to cast the spell, but the only problem is there is no werewolf to use it on. Cecil will ask if you know of any werewolf that could be a test subject for the spell.
You have three options to answer with. All of the options will lead to the same outcome, but some of those will result in hilarious lines of dialogue, so be sure to check them out.

You’ll then be tasked with performing the Homorphus Charm. Trace the wand movement on the screen to cast this spell.

Soon after, Cecil will inform you that he’s located Fenrir Greyback. Hit the GO button and proceed to the Training Grounds. When you arrive, you’ll encounter Fenrir and two of his werewolves.
They will surround Cecil while Fenrir sets his eyes on you. He’ll transform and just before he attacks you, Chiara will step in to defend you. Sadly, she won’t be able to stop him, and he’ll quickly send her flying to the ground.

For your next task, you need to defeat Fenrir in a duel. The task window will display the recommended attribute levels as well as the cost of each attempt.

The recommended attribute levels for this duel will always be one level higher than your attributes. Because of that, this duel is one of the hardest duels in the game, especially for Year 1 students. You will have a -2 damage penalty on every single damaging spell you use, which will put you at a significant disadvantage.
However, there is a strategy you can use to easily win this duel. At the time of writing this Walkthrough, Fenrir Greyback was always following the same pattern of moves. He would go Sneaky on turn 1, Defensive on turn 2, Aggressive on turn 3, Defensive on turn 4, and then repeat the same pattern until the end of the duel.
As for his moves, in Aggressive and Sneaky stance, Fenrir will hit you for 9 damage and leave a bleed effect that deals 3 damage per turn for 2 turns. In Defensive stance, Greyback will hit you for 7 damage and leave a bleed effect that deals 3 damage per turn for 1 turn. He also has a chance to stun you for 1 turn when he uses his Defensive move.
In order to easily defeat Fenrir, you should always force a draw whenever he is going Sneaky or Aggressive (on turns 1, 3, 5, 7, and so on). On turns when Fenrir is going Defensive (turns 2, 4, 6, 8, and so on), you should go Sneaky and hit him with Flipendo. That way, regardless of whether or not you get stunned, you will always deal more damage than you take. And since you are forcing draws on turns when Fenrir is going Sneaky or Aggressive, the stun effect will wear off during the draw.

Once you defeat Fenrir, Cecil will step in and cast the Incarcerous Spell to bind him.

You will notice that Chiara is still unconscious on the ground.

Thankfully, Cecil will decide not to capture her, but instead, take her to the Headmaster’s office. He’ll thank you for your help with everything. For the next task, you should proceed to the Great Hall.
When you get there, you’ll notice that Chiara is alive and well. You’ll be able to interact with her, Cecil and Penny by tapping on their speech bubbles.

Dumbledore will commend your bravery and soon after you’ll get your final task of this adventure. This one involves hanging out in the Great Hall and enjoying the Halloween Feast.
To complete it, you need to earn five stars within eight hours. All five stars are required to pass.

There are bonus progress actions tied to Professor Dumbledore, the Grey Lady, Cecil, Chiara, and your character. Prioritize those actions whenever they are available. This will save you some energy and enable you to complete the task faster.

When you are done, you will thank Chiara for helping you against Greyback. Moments later, Cecil will approach and congratulate you on becoming an honorary member of the Werewolf Capture Unit. He even got a uniform just for you.
Interestingly enough, you will learn that Greyback already escaped. Cecil will admit that the Werewolf Capture Unit often has trouble with holding the captured werewolves.

Shortly after, the Headmaster will animate some dancing skeletons to entertain everyone. It truly is a sight to behold.

With this, the Halloween Feast Adventure will be completed. Hit the Collect button to claim your reward – Werewolf Capture Unit Uniform and 3 Chocolate Frogs.

Be sure to check it out in your wardrobe.

You will also earn the achievement for completing the adventure.

With this, the thrilling adventure has come to an end. It definitely was a fun and interesting one. Thank you for reading and see you soon with more exciting adventures. Until next time!
