Hogwarts Diary Guide
Introduction
The Hogwarts Diary event is a limited-time feature designed to enhance storytelling in the game by allowing players to unlock and complete various pictures. These pictures represent key moments in the game’s story, and as you complete them, you’ll not only reveal parts of a larger narrative but also earn valuable rewards like in-game currency and special items.
This feature unlocks after completing Year 1, Chapter 8. Upon reaching this milestone, you’ll get a short introductory side quest titled The Hogwarts Diary, which rewards you with 100 Coins. After that, you can fully participate in the event.
Core Mechanics
The main goal of the Hogwarts Diary event is to collect Inkwells, which are used to reveal pieces of pictures. These Inkwells come in various rarities, and higher rarity Inkwells unlock more significant parts of the picture.
- Picture Completion: Once you collect all the pieces of a picture, the full image is revealed, unlocking a story segment and granting you rewards like coins or even exclusive in-game items.
- Time-Limited: Each event has a deadline for completing all pictures, so effective time management is key.
- Inkwell Packs: You will earn these by completing stars in tasks, with longer tasks offering better chances of receiving them.

Collecting Inkwells
Inkwells come in five rarities, with Rarity 5 being the rarest and most valuable. You can collect these by completing various in-game tasks, with different odds of obtaining an Inkwell Pack depending on task length and your current year in the game.
Chances of Receiving Inkwell Packs:
- 8-hour tasks: Guaranteed Pack
- 3-hour tasks: 47% to 78% chance, depending on your year
- 1-hour tasks: 21% to 43% chance
- 30-minute tasks: Lower chances, but still possible in later years

The higher your in-game year, the better your odds at receiving packs in shorter tasks.
Strategies for Maximizing Inkwells
- Prioritize 8-hour tasks: These always guarantee a Pack, so they are the most efficient way to gather Inkwells.
- Don’t ignore shorter tasks: Though they have lower chances, completing 30-minute and 1-hour tasks quickly can still help you gather Packs over time.
- Replay time-limited side quests: If you have replay options, these often reward Inkwells, so take advantage of them.
- Use duplicates wisely: As you progress, you’ll likely earn duplicate pieces. These are converted into Crystals, which can be spent on additional Inkwell Packs in the store.
Purchasing Inkwell Packs
If you find yourself short on Inkwells, you can buy Packs from the store using gems. Packs come with varying crystal rarities, and each pack has different probabilities of containing higher-tier Inkwells:
- 90 Gem Pack: 1-2 Crystals, with a focus on lower rarities
- 175 Gem Pack: 1-3 Crystals
- 455 Gem Pack: 1-5 Crystals
- 945 Gem Pack: Guaranteed missing picture piece
These packs can also appear in special offers or bundles during events, giving you additional opportunities to stock up.

Rewards and Bonus Events
Completing pictures in the Hogwarts Diary unlocks valuable rewards, including exclusive cutscenes, in-game currency, and special items. Occasionally, certain events like Crest events may offer additional opportunities to earn Inkwell Packs, so keep an eye on the event calendar.

Conclusion
The Hogwarts Diary event adds a new layer of engagement to Harry Potter: Hogwarts Mystery, combining puzzle-solving with narrative progression. By strategically collecting Inkwells and prioritizing tasks, players can unlock hidden stories and earn rewards. Focus on completing longer tasks to guarantee Inkwell Packs, use your Crystals wisely, and don’t miss opportunities in special events. With careful planning, you can successfully complete all the pictures and enjoy the full rewards of the Hogwarts Diary.
