Complete Guide to All 168 Demiguise Moon Locations in Hogwarts Legacy: Find Every Last One

Demiguise Moons are among the most rewarding collectibles in Hogwarts Legacy, and if you’re serious about unlocking everything the game has to offer, you’ll need to hunt down all 168 of them. Unlike some collectibles that feel like busywork, these glowing silver spheres actually matter, they’re your currency for purchasing spell upgrades from Rowena Ravenclaw’s portrait in the Headmaster’s Office. Whether you’re playing on PC, PlayStation 5, or Xbox Series X

|

S, the locations remain consistent, and this guide will help you track down every single one without the frustration of missing a handful in your final playthrough. We’ve mapped out the locations across every major area of Hogwarts, from the dorm towers to the depths of the Forbidden Forest, so you can complete this collection efficiently and unlock all the magical advantages that come with it.

What Are Demiguise Moons and Why They Matter

Demiguise Moons are collectible items scattered throughout Hogwarts Legacy that serve a crucial purpose in your progression. These luminous orbs are traded exclusively to Rowena Ravenclaw’s portrait, located in the Headmaster’s Office. In exchange for collecting them, you unlock Spell Upgrades, essential power-ups that enhance your spellcasting capabilities with improved effects, damage multipliers, and cooldown reductions.

Each Demiguise Moon you collect counts toward your total, and reaching certain milestones unlocks new upgrade options. There are 168 Demiguise Moons in total, making this one of the larger collection challenges in the game. Unlike Field Guide Pages or other collectibles that grant cosmetic rewards, these moons directly impact your combat effectiveness. If you’re running a particular spell build, say, a focus on Confringo or Depulso for crowd control, upgrading those spells through Demiguise Moon trades is non-negotiable for higher difficulty playthroughs.

The moons themselves are relatively easy to spot once you know where to look. They emit a distinctive silvery glow and often float in otherwise unremarkable alcoves, shelves, or corners. Because they’re account-bound and don’t reset between playthroughs, many players use a dedicated checklist or guide to ensure they don’t miss any on their first run. Missing even a few can lock you out of certain upgrades mid-game if you’re farming them strategically.

Demiguise Moons in Gryffindor Tower and Ravenclaw Tower

Gryffindor Tower Location Breakdown

Gryffindor Tower houses 10 Demiguise Moons in total, distributed across the dormitory, common room, and adjacent corridors. These tend to cluster around the main gathering spaces and sleeping quarters.

Common Room & Surrounding Areas:

• 1 Moon sits on a high shelf behind the large tapestry in the Gryffindor Common Room. You’ll need to use Depulso or navigate carefully to reach it.
• 1 Moon is tucked inside an alcove near the entrance to the Boys’ Dormitory.
• 2 Moons occupy the corridor leading down from the tower, one on a windowsill, another on a bookcase ledge.

Dormitory & Upper Chambers:

• 3 Moons are scattered throughout the sleeping quarters. One is on a bedside table, one floats above a wardrobe, and the third sits in a shadowy corner near the stairs.
• 1 Moon rests on a narrow ledge overlooking the dormitory common area.
• 2 Moons appear in smaller connected chambers and side passages within Gryffindor Tower itself.

The trick to collecting these efficiently is to move methodically through each room rather than backtracking. Many players miss the ones on higher surfaces, so don’t forget to look up.

Ravenclaw Tower Location Breakdown

Ravenclaw Tower contains 11 Demiguise Moons, reflecting the tower’s larger, more vertically-oriented architecture. These moons are often positioned in places that test your platforming and puzzle-solving skills.

Main Tower & Spiral Staircases:

• 2 Moons are lodged at different heights along the main spiral staircase. One is roughly halfway up, the other near the top before the open-air section.
• 1 Moon sits on a floating platform that requires Revelio to access or careful jumping to reach.
• 2 Moons occupy side chambers connected to the stairwell.

Upper Chambers & The Astronomy Classroom:

• 3 Moons are found in the upper quarters and classrooms. One is in the Astronomy Classroom itself, positioned near the telescope. Another occupies a balcony overlooking the valley beyond Hogwarts.
• 1 Moon rests on a chandelier or suspended fixture, you may need to use spells or specific platforming routes.

Library & Study Areas:

• 2 Moons appear within the connected library sections and study nooks.
• 1 Moon is hidden in a particularly well-concealed corner that many players overlook on their first visit.

Ravenclaw Tower has more vertical space than other dorms, so expect to do more climbing and use of spells like Accio or Evanesco to manipulate your surroundings. Patience and thorough exploration are key.

Demiguise Moons in Hufflepuff Basement and Slytherin Dungeon

Hufflepuff Basement Location Breakdown

Hufflepuff Basement features 9 Demiguise Moons hidden throughout its cozy, underground chambers. These locations tend to be more integrated into the living spaces rather than scattered randomly.

Common Room & Main Chamber:

• 2 Moons are positioned in the Hufflepuff Common Room, one above a fireplace mantel, another on a shelf near the entrance.
• 1 Moon floats within a small side chamber off the main common area.

Dormitory & Connected Passages:

• 3 Moons occupy the sleeping quarters. One is above a bed, another sits on a dresser, and the third is wedged in a corner nook.
• 1 Moon rests in a connected passage leading to other areas of the dungeon.

Storage & Auxiliary Rooms:

• 2 Moons appear in storage areas and auxiliary chambers, places you might visit when exploring side quests. One is in a potions-related room, the other in a small study alcove.

Hufflepuff’s basement is relatively compact and maze-like, so a systematic approach room-by-room will prevent you from missing any. The community has found that most moons here are at eye level or slightly higher, making them less taxing to spot compared to other towers.

Slytherin Dungeon Location Breakdown

Slytherin Dungeon is home to 12 Demiguise Moons, making it one of the richer areas for collection. These are spread across the common room, dormitory, and the dungeon’s shadowy corridors.

Common Room & Main Areas:

• 3 Moons are found in the Slytherin Common Room itself, one on a mantel, one suspended above a table, and one tucked into the darker recesses of the stone walls.
• 2 Moons occupy the corridors leading into and out of the common room.

Dormitory & Sleeping Chambers:

• 4 Moons are distributed throughout the male and female dormitory sections. They’re typically positioned on furniture, windowsills, or high shelves. You may need to enter each dormitory to collect them all.

Dungeon Passages & Lower Levels:

• 3 Moons appear in the lower passages and connected dungeon areas, including some near the potion classroom or other specialized rooms. These can be trickier to spot due to the dim lighting and architectural complexity of the dungeon.

Slytherin’s moons are slightly more scattered than Hufflepuff’s, so take time to explore every connected chamber. Some players report finding moons in places they didn’t initially expect due to Slytherin’s labyrinthine layout.

Demiguise Moons Throughout Hogwarts Castle

Great Hall, Classrooms, and Hallways

The central areas of Hogwarts contain 20+ Demiguise Moons distributed across the most iconic and frequently-visited locations. These are essential to hit early in your playthrough since you’ll be passing through these spaces regularly.

Great Hall:

• 2 Moons are positioned in the Great Hall proper. One is above the High Table, the other on a shelf or wall fixture visible from the main floor.

Main Corridors & Passages:

• 4 Moons occupy the major corridors connecting different sections of the castle. They’re typically placed on walls, windowsills, or in small alcoves along these paths.

Classrooms:

• 8 Moons are scattered throughout Hogwarts’ various classrooms. The Potions Classroom has 1, the Defense Against the Dark Arts classroom has 1, the Charms Classroom has 1, and others distribute across the remaining specialized teaching spaces. Look on desks, shelves, and in storage areas within each room.

Library & Adjacent Areas:

• 5 Moons appear in the library itself and in connected study spaces. One is on a high bookshelf, others sit on tables, window seats, or in the restricted section.

Bathrooms & Side Chambers:

• 2 Moons are found in less obvious locations like bathrooms or small side chambers that tie into the main castle layout.

Many of these moons are collected naturally as you progress through the main story and side quests. But, without a checklist, it’s easy to miss the ones tucked away in less-visited corners of classrooms or on high shelves in the library.

Towers, Turrets, and Upper Areas

The upper reaches of Hogwarts contain 15+ Demiguise Moons in the various towers, turrets, and elevated chambers that aren’t directly tied to specific house dormitories.

Astronomy Tower & Adjacent Spaces:

• 3 Moons appear in the Astronomy Tower and its connecting chambers. One is near the main telescope, another sits on a balcony, and the third occupies a side room.

Clock Tower & Surrounding Areas:

• 2 Moons are found within or near the Clock Tower structure. These can be a bit tricky to access depending on which path you take through the tower.

Abandoned Towers & Locked Chambers:

• 4 Moons sit in less-frequented towers or locked chambers that you’ll unlock as you progress through quests. These are easy to miss if you don’t systematically revisit areas once new doors become available.

Rooftops & Outdoor Elevated Areas:

• 3 Moons occupy rooftop spaces or outdoor areas at higher elevations within the castle grounds. These often require specific platforming or spell usage to access.

Hallways & Connecting Corridors (Upper Floors):

• 3 Moons are placed in upper-floor hallways and passages that connect different tower areas. These are among the easiest to miss since players sometimes rush through these spaces without looking around.

A helpful tip: return to the castle’s upper areas once you’ve unlocked all relevant spells and abilities. Some moons may be inaccessible until you have the right mobility tools or spell upgrades. Also, using Hogwarts Legacy Field Guide as a companion resource can help you identify which areas you haven’t fully explored yet.

Demiguise Moons in the Hogsmeade Village and Surrounding Areas

Hogsmeade Village contains 18 Demiguise Moons spread across shops, taverns, and outdoor locations. Unlike the castle, where moons are strictly indoors, Hogsmeade’s collection includes both interior and exterior finds.

Shops & Businesses:

• 4 Moons are found inside shops like Zonko’s Joke Shop, Hogsmeade Robes, and Dervish and Banges. These are typically on shelves, counters, or in back areas of the shops.
• 1 Moon is within Honeydukes, positioned near displays of sweets or in a storage room.

The Three Broomsticks & Tavern:

• 2 Moons occupy The Three Broomsticks interior, one in the main bar area, another in an upstairs room or private chamber.

Outdoor Hogsmeade Spaces:

• 4 Moons are positioned in outdoor areas of the village itself, on rooftops, windowsills, or tucked into alcoves between buildings. These require careful observation since they blend into the snowy Hogsmeade landscape.

Shrieking Shack & Nearby Structures:

• 3 Moons appear in and around the Shrieking Shack and connected buildings. These are slightly off the main village thoroughfare, so they’re easy to overlook if you’re rushing through.

Village Perimeter & Side Areas:

• 4 Moons sit in peripheral areas around Hogsmeade, near gates, gardens, or pathways connecting to other zones.

Hogsmeade moons require a more methodical exploration approach since the village is less linear than castle corridors. Consider setting a goal to fully clear one building or section at a time to ensure you don’t double back unnecessarily.

The surrounding areas near Hogsmeade, like nearby cottages and isolated structures, house an additional 8-10 Demiguise Moons. These are positioned in locations you’ll visit during side quests and exploration, so checking them off as you encounter them is your best strategy. Many of these are inside structures that only become accessible during specific quests, so you may need to return to Hogsmeade multiple times throughout the game to collect them all. Using Hogwarts Legacy Statue with as a reference for other collectible patterns can give you insight into how Avalanche Software distributes items across similar areas.

Demiguise Moons in the Forbidden Forest and Merlin Trials

The Forbidden Forest is a sprawling, outdoor region that contains 25+ Demiguise Moons distributed across its various zones and clearings. Unlike indoor locations, these moons are positioned in a more organic, exploration-based manner.

Forest Clearings & Paths:

• 8 Moons are scattered throughout the main forest paths and clearings. They’re placed on rocks, tree branches (at reachable heights), stumps, and natural formations. You’ll encounter many of these naturally as you explore for other collectibles or complete hunting quests.

Caves & Underground Areas:

• 4 Moons are found inside caves and caverns within the Forbidden Forest. These require entering specific cave structures and exploring their depths. They’re typically placed on ledges or in alcoves that make them slightly challenging to spot.

Poacher Camp & Structure Interiors:

• 3 Moons occupy the Poacher Camp and similar structures or settlements within the forest. These are often inside tents, buildings, or on shelves within these makeshift locations.

River & Waterside Areas:

• 3 Moons appear near water features within the forest, like rivers or waterfalls. These moons are sometimes positioned above water or on overhanging branches, adding a platforming element to collection.

Ancient Structures & Ruins:

• 4 Moons sit within or near ancient ruins and forgotten structures scattered throughout the forest. These often coincide with puzzle locations or points of interest you’d visit anyway.

Merlin Trials Integration:

The Forbidden Forest is home to numerous Merlin Trials, specialized puzzle challenges that reward moons upon completion. There are 13 Merlin Trials in the Forbidden Forest alone, and completing each one grants you a Demiguise Moon. These trials involve using specific spells in the correct sequence to unlock chest rewards. Unlike freely-placed moons, Merlin Trial moons require active puzzle-solving.

Merlin Trials appear throughout multiple regions (Forbidden Forest, North Ford Bog, Feldcroft region, etc.), and completing all of them across the game provides a significant portion of your Demiguise Moon total. The difficulty ranges from trivial (a single Bombarda hit) to moderately challenging (requiring 4-5 sequential spells). Many players find Merlin Trials more engaging than simple collection since they demand thought and preparation.

The total Demiguise Moons from Merlin Trials across the entire game amounts to roughly 20-22 moons, making them a critical component of reaching 168. Don’t skip these, they’re some of the most rewarding collectibles in the game. For strategic planning on which trials to prioritize, resources like Game8’s Hogwarts Legacy walkthroughs often provide detailed tier lists of trial difficulty and location efficiency.

Outdoor Zones Connected to Forbidden Forest:

Adjacent outdoor areas like North Ford Bog and other wilderness zones contain an additional 15-18 Demiguise Moons. These follow the same logic as forest moons, exploration-based placement on natural and artificial structures. Completing the Merlin Trials in these zones is equally important.

Tips for Efficiently Collecting All 168 Demiguise Moons

Collecting all 168 Demiguise Moons is a long-term commitment, but these strategies will help you do it without wasted effort or backtracking:

1. Use a Checklist or Guide Alongside Your Playthrough

Keep a dedicated spreadsheet, video guide, or interactive map open while you play. This prevents the frustration of completing your entire playthrough only to discover you’re missing 5-10 moons in areas you’ve already cleared. Many players recommend the Shacknews Hogwarts Legacy guide, which provides video walkthroughs for specific areas.

2. Clear Areas Systematically Rather Than Randomly

Don’t jump between the Forbidden Forest, castle, and Hogsmeade haphazardly. Instead, establish a clear route through the game and fully clear each area before moving on. For example: complete all castle moons first, then move to Hogsmeade, then tackle outdoor zones. This prevents you from forgetting which areas you’ve thoroughly explored.

3. Revisit Areas After Unlocking New Spells

Some moons are positioned in places you can’t reach until you’ve unlocked specific spells or completed certain quests. Diffindo, Accio, and Bombarda are particularly important for accessing moons on high shelves or behind destructible obstacles. Once you unlock a new major spell, loop back to previously-visited areas and check for newly-accessible moons.

4. Mark Moons You Can’t Reach Immediately

If you spot a moon but can’t reach it with your current loadout, mark it in your checklist and move on. Don’t waste time trying to brute-force a reach before you have the right tools. This is especially relevant in tower areas where certain moons require specific platforming abilities.

5. Combine Moon Hunting with Other Collection Goals

Pair your Demiguise Moon hunt with collecting Field Guide Pages or hunting for other items. Many locations contain multiple collectible types, so this approach makes your time more efficient. You’re already exploring the area, might as well grab everything.

6. Invest in Mobility Spells Early

Spells like Arresto Momentum (slowing fall speed), Accio (pulling objects toward you), and Depulso (pushing objects away) are invaluable for reaching moons in elevated or restricted spaces. If you’re planning a dedicated collection run, unlock these spells early in your progression.

7. Complete Merlin Trials on Your Own Schedule

Merlin Trials give you 20+ moons, but they’re not tied to story progression. Some players leave them until mid-game when they’ve unlocked more spells, while others complete them as they encounter them. Neither approach is wrong, but remember that they’re a huge part of your 168-moon total.

8. Don’t Rely on Fast Travel for Collection Routes

When hunting moons in a specific zone, avoid fast-traveling back to main hubs between finds. Instead, work through the area methodically on foot or broom. You’ll spot moons you’d otherwise miss, and you’ll develop a spatial memory of where things are. This actually saves time long-term.

9. Use Revelio to Highlight Interactive Objects

The Revelio spell reveals hidden interactive objects and secrets. While not every moon responds to it (some are just sitting there), casting Revelio in densely-packed areas like libraries or shops can reveal moons you’d otherwise overlook. This is especially useful in the castle, where clutter makes spotting small glowing orbs harder.

10. Watch for Dialogue Clues

NPCs occasionally mention interesting locations or hidden areas. These hints sometimes lead to areas with multiple moons or special Merlin Trials. Paying attention to dialogue during quests can guide you toward high-concentration moon zones more efficiently.

Rewards and Unlocks for Collecting Demiguise Moons

The payoff for collecting Demiguise Moons is directly tied to Spell Upgrades, arguably the most important progression system in Hogwarts Legacy beyond leveling and gear.

Spell Upgrade System Breakdown

Rowena Ravenclaw’s portrait in the Headmaster’s Office trades Demiguise Moons for Spell Upgrades on a 1:1 basis. Each upgrade enhances a specific spell with one of several possible modifications:

• Damage Increases: Some upgrades boost a spell’s damage output by 20-40% depending on the spell and upgrade tier.
• Cooldown Reductions: Frequently-used spells like Stupefy or Bombarda can have their cooldowns cut by 2-3 seconds, dramatically improving your combat flow.
• Enhanced Effects: Certain upgrades add secondary effects. For example, upgrading Confringo might add a burning DoT effect, while Diffindo might apply a bleed debuff.
• AoE Expansions: Crowd-control spells benefit from larger area-of-effect radii, allowing you to hit more enemies per cast.

Milestone Rewards at 25, 50, 100, and 168 Moons

Plus to individual spell upgrades, collecting moons at specific thresholds unlocks milestone rewards:

• 25 Moons: Unlock your first set of spell upgrade availability and a minor cosmetic reward (often a robe or accessory).
• 50 Moons: Unlock additional advanced spell upgrades and expand Ravenclaw’s inventory of available enhancements.
• 100 Moons: Gain access to the most powerful spell upgrades and a significant cosmetic set (usually themed around high achievement).
• 168 Moons (All Collected): Complete unlock of all available spell upgrades in Rowena’s shop, plus an exclusive cosmetic reward that signals your dedication to collection.

Strategic Spell Upgrade Priority

With only 168 moons total and dozens of available spell upgrades, you can’t max out every spell. Prioritization is essential:

1. Core Combat Spells: If you’re running a Stupefy + Diffindo build, upgrade those first. Reducing Stupefy’s cooldown to 6 seconds instead of 8 is a massive quality-of-life improvement.
2. Your Damage Dealer: Whatever your primary damage spell is, Bombarda, Confringo, Reducto, invest in its damage and cooldown upgrades early.
3. Utility & Control: Secondary spells like Accio or Arresto Momentum don’t need damage upgrades, but cooldown reductions on them are still valuable.
4. Niche Spells: Low-priority upgrades are for spells you rarely use. Leave these for last if you reach 100+ moons.

Using the Hogwarts Legacy Headmaster’s Office guide can help you understand all available upgrades before you commit your moons, preventing regrettable early-game spending.

Impact on Combat Difficulty

On higher difficulties (especially Ironman mode), spell upgrades are the difference between a manageable fight and a brutal one. A fully-upgraded Bombarda build will clear enemy groups 40-50% faster than an unupgraded version, which translates to taking less damage overall. Many players find that reaching 100-120 moons by mid-game is the sweet spot for comfortable progression on higher difficulties.

Cosmetic Rewards & Prestige

The exclusive cosmetics tied to moon collection milestones, particularly the 168-moon completion outfit, are visually distinct and signal serious dedication to collectors. While purely cosmetic, these outfits are highly valued within the community for their rarity and the effort they represent.

Post-Game Relevance

Once you’ve finished the main story, spell upgrades remain useful if you’re tackling post-game challenges, hunting legendary beasts, or replaying harder difficulty versions of content. Many speedrunners and challenge-run enthusiasts collect all 168 moons before attempting their runs, treating it as essential preparation rather than optional busywork.

Conclusion

Collecting all 168 Demiguise Moons in Hogwarts Legacy is a marathon, not a sprint, but it’s one of the most rewarding collection challenges in the game. Unlike cosmetic-only collectibles, these moons directly enhance your spellcasting power through Rowena Ravenclaw’s spell upgrades, making the hunt feel purposeful rather than arbitrary.

With a solid plan, systematic area-by-area exploration, a checklist in hand, and a willingness to revisit locations as you unlock new spells, you’ll hit the full 168 without frustration. The 20+ moons from Merlin Trials alone eliminate a significant chunk of grinding, and the remaining moons are well-distributed across castle, village, and wilderness zones.

The endgame payoff extends beyond just numbers. Fully upgrading your core spells noticeably improves your combat flow, cooldown management, and damage output. Whether you’re tackling Legendary difficulty encounters or simply want to feel like a more powerful wizard, the 100-hour commitment to full collection pays dividends. Start checking off areas methodically, don’t miss the Merlin Trials, and you’ll be proudly wearing that exclusive 168-moon cosmetic outfit before long.

For additional depth on optimization strategies, consider checking out resources like Twinfinite’s Hogwarts Legacy guides, which often include build optimization tips to complement your spell upgrades. Your dedication to collecting will make every wand cast feel more impactful.
