Hello everyone, welcome to Part 4 of our Walkthrough for Duelling Deathday Parties Adventure for Harry Potter Hogwarts Mystery. During the previous part, Nearly Headless Nick asked for your help to find the perfect venue for his Deathday party. After considering the options, you suggested the Training Grounds. Unfortunately, Madam Hooch was against the idea, but she helped you figure out the next best option, the dungeons. Nick was pretty content with having his party in the dungeons, so that matter was settled. Later on, after having a conversation with Merula and you, he made a decision to sabotage Erling’s Deathday feast, and he asked both of you to help him with it. You went to the Great Hall and successfully froze Erling’s feast, but before you could leave the hall, Professor Sprout arrived, shocked to see what you’ve done. Once you start this part, Nearly Headless Nick will ask you to meet with him in the Courtyard. Proceed there when you are ready.

Moments later, Nearly Headless Nick will arrive, saying he needs to talk to both of you.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

You will ask him if everything is all right.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

Sir Nicholas will say he managed to come to an agreement with Professor Sprout.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

He also promised her he would talk to Merula and you about what you did in the Great Hall.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

This requires earning five stars within three hours. All five stars are needed to pass, which is why you shouldn’t start this task if you are low on energy.

There are 5-cost actions linked to Merula and Nearly Headless Nick. Prioritize those if you want to save as much energy as possible.

By the looks of it, neither you nor Merula will get any further punishment for what you did.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

Apparently, Nick took the full blame for everything.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

Apparently, Nick was not aware that Professor Sprout was helping with food preparation for both parties.

The Most Powerful Witch at Hogwarts won’t seem to care about that.

Sir Nicholas, on the other hand, will feel terribly sorry for everything.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

He will ask both Merula and you to forgive him.

Suddenly, Erling the Great will arrive.

Unfortunately, Myrtle won’t be interested in going anymore.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

You will be curious to know why she had a sudden change of heart.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

She’ll say that the other ghosts don’t want her there.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

As it seems, you’ll have to convince her to attend the party.

Soon enough, you’ll decide to go to Sir Nicholas’s Deathday party.

Harry Potter Hogwarts Mystery Walkthrough Duelling Deathday Parties Part 4

Unfortunately, Nick hasn’t completed all of the preparations just yet, and it will take him around three hours to do so. Since you’re probably low on energy at this point, it is recommended to wait and let your energy recharge in the meantime.
