Merlin Trials in Hogwarts Legacy: complete puzzle guide and rewards

Merlin Trials in Hogwarts Legacy: a complete puzzle guide and reward overview

Merlin Trials are short, mechanically varied exploration puzzles that dot the highlands of Hogwarts Legacy. Solving them is the single best way to expand your Gear Inventory, which means more room for the legendary outfits, beasts, and quest rewards the rest of the game keeps handing you. There are 95 trials spread across every major region, and each one belongs to a small set of solution families that repeat with new geometry. Once the pattern of a trial is in your head, the open world becomes a checklist of satisfying five-second puzzles rather than a maze of confusion.

This guide is written for players who want to understand the system before they sprint across the map. It explains how to unlock the activity, how the Mallowsweet economy works, what each trial type expects from you, and how to plan a route that respects travel, vendor timers, and your own pace. It also covers the design logic behind the puzzles from a development angle, because the Merlin Trials are a useful case study in how a large open world layers short, repeatable, low-friction content without breaking exploration pacing.

How to unlock Merlin Trials and what you need to start

Merlin Trials are gated behind a single main story beat. You cannot interact with any of the 95 puzzles until the Trials of Merlin mission in Lower Hogsfield is finished. Once that quest wraps, the trial markers appear on your map and the game enables the interaction prompt at each location, but it will not let you begin a puzzle without Mallowsweet Leaves in your inventory.

Mallowsweet is the resource that turns a visible puzzle into a solvable one. Without it, a trial is just a sculpted stone formation that ignores your wand. With it, the formation activates and presents the challenge you actually came for. The leaf is a soft gate rather than a hard progression wall: nothing else in the main story requires it, and the only direct cost to doing every trial is the time you spend gathering leaves and walking between them.

The Mallowsweet economy

You begin with five Mallowsweet Leaves thanks to Nora Treadwell’s gift after the unlocking quest. Those five are enough to dip your toe in, but they are not enough to clear the entire highland. You have two realistic sources for more leaves, and the game pushes you toward one of them through vendor inventory and timers.

• Vendor purchase. The Magic Neep in Hogsmeade, Leopold Babcocke near Hogsmeade Station, and Arn in Hogwarts Valley all stock Mallowsweet. The problem is stock size and restock cadence. Each vendor holds only a handful of leaves at a time, and once they sell out they do not restock for 2.5 in-game days. Treating vendors as a primary source turns a long walk into a slow waiting game.
• Growing Mallowsweet. The reliable approach is to purchase the spell that lets you cultivate the plant, then dedicate a small patch of land in the Room of Requirement to it. The spell is the more sustainable investment because it converts idle time into a steady supply of leaves without forcing you to wait on merchant cycles.

If you plan to clear every trial, budgeting Mallowsweet before you start a route is the single most useful habit. A run that burns five leaves and then idles for a vendor restock is the most common reason players stall halfway through the highlands.

The core reward: Gear Inventory Slots and why they matter

Every Merlin Trial you complete grants one Gear Inventory Slot. The slot is permanent and applies to your overall carry capacity, so the rewards compound over the course of a playthrough. The number of slots you can earn is fixed by the total trial count, which is what makes the activity a long-term inventory project rather than a quick side quest.

More inventory means fewer forced decisions about which legendary piece to keep. The base game hands you a steady stream of gear with stat rolls you actually want to test, and without extra slots you end up selling or destroying items that turn out to be useful two hours later. The trials exist, in part, to relieve that pressure. Treating the activity as a way to widen the carrying capacity of the wizard you actually play, rather than as a checklist, changes how the entire gear grind feels for the rest of the run.

How trials compare to other exploration challenges

Hogwarts Legacy splits its open-world content into several challenge families, and each one trades time for a different kind of reward. The table below shows where the Merlin Trials sit in that economy.

The Merlin Trials are the densest reward-per-minute challenge in this list, which is why speedrunners and completionists both prioritize them. They are also the only exploration challenge in the base game that targets your carry capacity, which makes them functionally unique even though the surface activity looks like a generic collectible hunt.

The full set of Merlin Trial puzzle types

All 95 trials fall into a small number of mechanical families. Every individual trial is a fresh arrangement of one of these templates, which is why reading a single walkthrough teaches you most of the game. Recognizing the family from a few seconds of inspection is faster than rereading a guide at every marker.

Stone block arrangement trials

The most common trial type. You will find a cluster of stone blocks on the ground in front of a central platform. The blocks need to be moved with the basic Levioso spell, guided through the air, and placed in a specific pattern that usually mirrors an arrangement hinted at by markings on the platform or the surrounding stones. The block count varies, and the silhouette you have to recreate is always readable if you stop to look at it before you start lifting.

The mechanics here are simple but the timing is not. Blocks swing under Levioso, so you have to feather the cast to settle them on their targets. A small overcorrection is usually harmless because the blocks respawn, but a constant overcorrection is the main reason these trials drag on for several minutes the first time you try them.

Statue and fire bowl trials

You will find a set of statues with empty bowls and a stand holding a fire source. Conjuring a flame with Incendio at each bowl lights it, and lighting all of them within a short timer triggers the completion. The trick is to start the timer as late as possible so the chain has more breathing room. Walk to the furthest bowl first, ignite it last, and only kick off the chain when you are confident you can sprint between the rest.

Some variants use small braziers instead of statues. The mechanical intent is identical: deliver a flame to a set of objects in a time window. The variation is only there to keep the silhouettes fresh across regions.

Cube and sphere physics trials

A few trials replace stone blocks with cubes or spheres that you roll or push into recessed slots. These trials often look like classic push-the-block puzzles. The constraint is that the slots are usually narrow and the rolling objects can overshoot easily, so a measured push from the side is more reliable than a strong frontal shove. The geometry almost always includes a second, easier path that goes around a low wall, and the easiest solution is to look for it before you start brute-forcing the front.

Lumos and dark cave trials

Some trials take place in partially collapsed rooms or caves where the only meaningful mechanic is visibility. Activating Lumos lights the area and reveals a hidden pattern of glyphs or switch stones. The hidden pattern is the real puzzle, not the lighting itself. Once you can see the floor, the trial usually reduces to standing on marked stones in the right order or dragging a beam of light across a wall inscription.

These are the trials most affected by the time of day cycle, because ambient darkness affects how quickly the glyphs read. If a cave trial feels unreadable, fast travel to a nearby Floo flame and return to reset the local lighting and the spawn of any moving elements.

Platform and timing trials

A small set of trials revolve around moving platforms, swinging pendulums, or disappearing runes. The pattern is always the same: reach a central structure before a timer or a sequence expires. The reliable approach is to scope out the geometry from a distance, plan a route, and then commit. Re-attempts after a failure are immediate, so the cost of dying is low, but the cost of rushing without a plan is high.

Defensive and combat-adjacent trials

A few trials present a small set of enemies in front of the puzzle object. Clearing the enemies is the only way to interact with the puzzle. These trials are mechanically simple but they are a useful mid-route breather because they give you a moment to cast potions or set a sign before you solve the puzzle proper.

Symbol and riddle trials

The rarest family. For additional context, These trials present a riddle etched on a stone or given by a ghost, and the answer maps to a specific environment interaction: a painting to look at, an animal to find, or a phrase to call out with a spell. They are the only trial type where a guide is genuinely useful, because the riddle text is often written in archaic phrasing that does not translate to obvious actions.

The table below summarizes the families, the most common failure mode for each, and the practical habit that fixes it.

Where the 95 Merlin Trials sit across the regions

The trials are scattered across every major region of the highlands, with a smaller cluster inside the castle and the immediate castle grounds. The exact count per region is fixed, and the same number applies across platforms. The pattern below comes from the in-game region map. Use it as a planning tool, not a substitute for opening your own map, because the placement of individual trials can change slightly with patches and the Switch release.

The split is intentional from a design perspective. The early clusters are walking-friendly because the player is on foot and still learning the broom. The later clusters are large and broom-heavy, which lines up with the broom upgrade the main story delivers. This is why doing every trial in region order tends to feel natural, while doing them in random order often costs a lot of travel time.

A practical route plan for clearing the map

Most players treat Merlin Trial completion as a single multi-hour sweep rather than a series of small errands. A good sweep is built around three constraints: how Mallowsweet moves through your inventory, how the broom connects the regions, and how the Floo flame network supports fast travel. The list below is the order that minimizes travel for the largest number of players.

1. Start in Hogwarts Valley and the South Hogwarts Region. These clusters are close together and easy to walk, which lets you burn through the first ten or so trials before you have to think about broom travel.
2. Move into Hogsmeade Valley. Pair trials with the main quest path through the valley so you solve two objectives per long walk.
3. Push into Feldcroft and the northern fields. The broom upgrade from the main story is normally available by this point, and the distances in these regions reward a good broom.
4. Sweep the North Ford Bog. The bog is large, the trials are spread out, and the ground is slow on foot, so plan to broom between markers and Floo back to the closest flame when you run out of Mallowsweet.
5. Handle the coastal regions. The coastline rewards a broom even more than the bog, because there is little cover for ground mounts and the trials often sit on small rocks or short piers.
6. Finish in the castle grounds and the Forbidden Forest perimeter. These clusters are walkable, but they are best saved for last because they overlap with the final story chapters.

If you stick to this order, the travel time between consecutive trials stays small, and you avoid the worst version of the Mallowsweet problem, which is running dry in a remote region with no vendor in fast-travel range.

Managing Mallowsweet like a resource

Mallowsweet is a soft currency, and a few habits make the entire sweep less painful. The first habit is to never let your stock drop below ten leaves unless you are about to fast travel to a vendor. The second is to use the Room of Requirement planter as the primary source, because growing the plant is a fixed-time investment that pays back the rest of the playthrough. The third is to treat vendor restock as a fallback, not a plan, because the 2.5 day timer can stall a sweep if you rely on it.

The fourth habit is to keep a small mental count of how many trials are left in a region before you commit to a long broom run. If the count is higher than the leaves in your inventory, route through a vendor first. The cost of a short detour is always less than the cost of being stuck on a clifftop with no leaves and no fast travel for ten minutes.

How many Mallowsweet Leaves you actually need

Each trial consumes one leaf. With 95 trials in total and a five-leaf head start, the full sweep needs 90 additional leaves. Growing the plant in the Room of Requirement produces leaves on a regular cadence, and that cadence is faster than any vendor can match once the planter is set up. The practical recommendation is to start the planter the moment it becomes available and let it accumulate for an hour or two of real time before you commit to a long sweep. By the time the broom is upgraded, the planter has produced enough to keep a region-by-region run fed without vendor interruptions.

Troubleshooting common Merlin Trial problems

Most Merlin Trial failures are caused by one of a handful of issues. The list below pairs the symptom you will see with the cause and the cleanest fix.

• The trial does not activate when you cast a spell. You are out of Mallowsweet Leaves. Open the map, set a waypoint to the closest vendor, and restock before returning.
• Blocks refuse to settle on the targets. You are overshooting the platform edge. Drop the cast early, walk the block down with feathered inputs, and try again.
• The fire bowl timer expires immediately. You started the chain from the closest bowl. Walk to the furthest bowl first, ignite it, and only then move back toward the start to trigger the timer.
• You cannot see the glyphs in a cave trial. Lumos is at a low angle or the camera is too close. Raise the wand higher and back the camera away until the floor pattern is readable.
• The trial marker disappears after you arrive. You are standing too close. Merlin Trial markers can clip out of view at very short distances, so back up a few meters until the icon returns and the prompt reappears.
• A platform trial restarts before you reach the structure. You started before scoping the path. Let the timer run out, watch one full cycle, and then commit to a clean run.

These are the same failure modes that show up across every guide for the system, which is a useful signal in itself. The fact that the same six problems appear in most help articles is a strong hint that the trial design is consistent and forgiving: once you internalize the habit, the same fix works at every marker in the same family.

Why Merlin Trials are a useful design case study

From a production angle, the Merlin Trials are a tight example of how a large open world layers short, repeatable content. Each trial is small enough to solve in under two minutes, the input vocabulary is shared with combat and exploration, and the reward is a permanent character upgrade that motivates long-term engagement. The trial families are also distinct enough that a player never feels like they are doing the same thing twice, even though the underlying mechanics are a small set.

The trials also demonstrate a few patterns that are worth noting if you are studying or building open-world systems:

• Recognition over recall. Each trial belongs to a small number of mechanical families. Once the family is recognizable, the player solves the trial by recognizing geometry, not by remembering instructions.
• Soft gating through a single resource. Mallowsweet is a soft gate that paces the activity without locking it behind story progression. This lets the player choose when to engage without losing access to the reward permanently.
• Reward that compounds the core loop. Gear Inventory Slots are useful to every player, which removes the usual completionist tax of rewards that only matter to specific builds.
• Region pacing that respects travel upgrades. The trial density and travel character of each region line up with the broom upgrade, which means the player is never forced to do a long broom run before the broom is available.

None of these are accidental. The trials are the cleanest example in Hogwarts Legacy of a content layer that respects the player’s time without dumbing down the activity, and the design lessons generalize well to any open-world game that wants to add a long-tail exploration activity without breaking pacing.

How Merlin Trials interact with the rest of the completion loop

The Hogwarts Legacy completion percentage pulls from a long list of activities, and Merlin Trials are one slice of that pie. The trials are not required to finish the main story, but they are required if the player wants the full inventory upgrade the base game offers. They also tend to overlap with the other exploration challenges, which is why a careful sweep through a region often hits several collectible types at the same time.

The list below shows the activities that pair well with a trial sweep, and the order that tends to keep travel short.

• Ancient Magic Hotspots. These are short combat arenas that grant spell XP. They are common in the same regions as the trials and can be solved between trial markers without a long detour.
• Demiguise Statues. The Demiguise hunts are a stealth activity that pairs well with evening or night play. They are best handled on the same sweep as the trials, because the routes overlap.
• Flying Field Guide Pages. The broom pages are the natural filler between two distant trial markers, because you are already on a broom and the pages are usually close to your line of travel.
• Beast Dens. The dens sit in the same regions as the trials. The dens are a useful mid-sweep stop because they let you pick up materials for upgrades without leaving the route.

Pairing these activities with the trial sweep is the single best way to keep the late-game exploration loop feeling like one continuous play session rather than a series of disconnected errands. If you are interested in how those other activities feed into the broader progression loop, the same patterns show up in our broader coverage of exploration systems and open-world design.

Common myths about Merlin Trials

Because the trials are popular with completionists, a few pieces of community advice have hardened into folklore that does not actually hold up. The list below is the short version of the most common myths and what the real behavior is.

• Myth: missing a trial is permanent. False. Every trial in the base game is a static marker. If you cannot find one, it is more likely that the marker is off-screen at your current distance, or that you are in the wrong altitude band for the Floo network to draw it on the map.
• Myth: trial rewards cap below the inventory you actually need. False. The slot count is exactly tied to the trial count, and finishing all 95 is what gives you the maximum carry capacity the base game offers.
• Myth: vendors are the only reliable Mallowsweet source. False in the long run. The Room of Requirement planter is the sustainable source, and vendors are best treated as a fallback for short windows.
• Myth: every trial needs a broom. False. Many trials are within walking distance of Floo flames, and the broom is only the dominant travel tool in the bog and the coastal regions.

These myths are mostly harmless, but they can derail a sweep if you plan around them. The activity is more forgiving than the community makes it sound, and the design supports a slow, region-by-region pace rather than a single marathon.

What to do once every Merlin Trial is done

Once all 95 trials are complete, the practical effect is the maximum Gear Inventory the base game allows. The main story and most side content remain unchanged. There is no bonus dungeon, no exclusive cosmetic, and no extra quest line. The reward is structural, not narrative, and it is most visible in the late game when you have a long list of legendary gear you actually want to keep.

If you are aiming for 100 percent completion, the trials are one slice of a larger checklist that includes Demiguise Statues, Ancient Magic Hotspots, Field Guide Pages, and the broader collection of regional challenges. The trials are the densest reward slice in that checklist, which is why most completionists clear them first and let the other activities fill the remaining gaps.

Frequently asked questions

How many Merlin Trials are there in Hogwarts Legacy?

There are 95 trials in the base game. The count is the same on PC, PlayStation, Xbox, and Switch. Every trial grants one Gear Inventory Slot, so finishing all of them unlocks the maximum carry capacity the base game offers.

How do you unlock Merlin Trials?

Trials unlock after the Trials of Merlin main story mission in Lower Hogsfield. Once that quest is finished, the trial markers appear on the map, but you still need Mallowsweet Leaves in your inventory to actually start each puzzle.

Where do you get Mallowsweet Leaves?

You start with five leaves from Nora Treadwell. After that, you can buy more from the Magic Neep in Hogsmeade, Leopold Babcocke near Hogsmeade Station, or Arn in Hogwarts Valley, with a 2.5 day restock timer. The more reliable source is to purchase the planter spell and grow Mallowsweet in the Room of Requirement.

Do you need a broom for every Merlin Trial?

No. The early trial clusters in Hogwarts Valley, the South Hogwarts Region, Hogsmeade Valley, and the castle grounds are walking-friendly. A broom is most useful in the North Ford Bog, the coastal regions, and Feldcroft, where the trial markers are spread across long distances.

What happens if you run out of Mallowsweet mid-sweep?

The current trial simply refuses to start, and the prompt tells you that you are missing Mallowsweet. The cleanest response is to fast travel to the closest vendor, restock if the vendor has inventory, or wait for the Room of Requirement planter to produce more leaves.

Are Merlin Trials missable?

No. Every trial is a static marker on the map, and none of them are tied to a story decision. If you cannot find a marker, you are usually too close to it for the icon to render, or you are outside the altitude band the map uses to draw the marker.

Do Merlin Trials carry over to a New Game Plus run?

The trials reset with the rest of the open world content in a New Game Plus run. Because the reward is a permanent inventory upgrade, the trials are most useful in the playthrough where you intend to use the extra slots the most.

What is the fastest way to clear all 95 Merlin Trials?

The fastest realistic approach is to start the Room of Requirement planter early, wait until the broom upgrade from the main story is available, and then sweep the regions in the order that minimizes travel: Hogwarts Valley, South Hogwarts, Hogsmeade Valley, Feldcroft, North Ford Bog, the coastal regions, the Forbidden Forest perimeter, and finally the castle grounds.

Do Merlin Trials scale with difficulty or level?

The puzzles themselves do not scale. The combat-adjacent trials do scale with the surrounding enemy population, but the core puzzle mechanics are consistent from the first trial to the last. The activity is paced by Mallowsweet and travel, not by player level.

Are there Merlin Trials in Hogwarts castle itself?

Yes, there is a small cluster in the castle grounds and on the towers. These are walking-friendly and are best handled as a clean-up sweep after the main story progression has opened every door you need.
