The 16 Hogwarts Valley Merlin Trials in Hogwarts Legacy are required to unlock Merlin’s Beard! Trophy/Achievement. Solving the 16 Trial puzzles in the Hogwarts Valley region will also help you complete Challenges and increase the size of your inventory. But before you can start any Trial, you must first complete the Trials Of Merlin main quest, where you meet Nora Treadwell, who teaches you everything you need to know about these puzzles that are scattered all over the open world.
You’ll also need to have Mallowsweet Leaves in your inventory to start a Trial, and they can be found in the open world or grown at a potting table in the Room of Requirement, provided you’ve bought the Mallowsweet Seed Recipe from The Magic Neep shop in Hogsmeade.
Where To Find All Hogwarts Valley Merlin Trials in Hogwarts Legacy
First, you should check the following Hogwarts Valley map. On it, I’ve marked the locations of all 16 Trials, which, as you can see, are scattered all around the area.
Merlin Trial #1: East of the Brocburrow Hamlet
The first Hogwarts Valley Trial is found east of the Brocburrow hamlet in the northeastern corner of the region. Once you reach the spot, if you can’t see the Trial’s altar, look at your minimap because its icon should appear when you get close enough. Interact with the altar to start the Trial, then turn to the southeast to spot a couple of stones. To solve the puzzle, you must go to the first stone on the opposite side of the altar. Then, jump from stone to stone without touching the ground, and you complete the Trial.
Merlin Trial #2: In Brocburrow
For the second Hogwarts Legacy Trial, you need to go to Brocburrow, and you’ll find the altar west of Hamlet’s Floo Flame. Start the Trial and head southeast to find a hole in the ground. Now, go uphill to the south of the hole to find a boulder next to some rocks.
The trick is to get the boulder in the hole from before. To do so, you have to use the Depulso spell on the boulder to push it downhill. Also, you’ll need to destroy the rocks standing in the way of the boulder. You can clear the path by simply using basic attacks on the rocks.
Merlin Trial #3: West of Brocburrow
The next Merlin Trial will take you not too far west of Brocburrow at the third location pinpointed on the map above. After you start the Trial, you need to find three stones with diamond-shaped holes and three groups of fireflies. The trick is to bring the fireflies to the stones; to accomplish this, you need to use the Lumos spell.
The stones are really close to the altar, one to the northeast, another northwest, and the last south. As for the fireflies, one group is to the east, another north, and the last to the west. Now go to each group of fireflies and make them follow you to the stones by casting Lumos near them. You have to take one Firefly group at a time. Also, a stone can’t hold more than one group. You can see all the stones and firefly groups if you get on your Broom and gain some altitude, just like in the next image.
Merlin Trial #4: Near a River
Another Merlin Puzzle in Hogwarts Valley is southwest of the Central Hogwarts Valley Floo Flame. Check our map for the exact location. After reaching the place, you can see the altar near the river. Don’t forget to check your minimap for the Trial’s icon if you can’t find the altar.
Now start the Trial, go to the river, and look for the three torches you need to light up. One torch is next to the stone bridge southwest of the altar, and the other two you can find by following the river to the northwest, as shown in the following screenshot.
To solve this puzzle, you need to light the torches pretty fast using the Confringo spell, and we suggest you do it in the same order as the one in the previous image. It would be best to position yourself near the shortest torch to reach all of them fast without wasting time moving too much. The range of Confringo is quite big, so it shouldn’t be a problem.
Merlin Trial #5: South of the Lower Hogsfield Hamlet
The fifth Trial is south of the Lower Hogsfield hamlet in the northern part of the area. When you arrive at the fifth location on our map, start the Trial for which you have to destroy nine balls scattered around the altar. The balls are placed on top of small pillars, and you can see them easily, even through objects, if you cast Revelio, like in the image below. Destroy all nine balls with basic attacks to complete the Trial.
Merlin Trial #6: Northwest Of The West Hogwarts Valley Floo Flame
The sixth Hogwarts Valley puzzle is found northwest of the West Hogwarts Valley Floo Flame in the northwestern corner of the region. Interact with the altar, then head south to find a platform with four holes in it. Also, on the cliff left of the platform, you can find five balls.
You must use Accio on the balls to place them on the platform. Hold the button you have assigned for Accio to guide the balls. The platform starts spinning when you’ve placed the balls correctly. Then, look for a second platform east of the altar and another five balls in the tent north of the platform. The third and last platform is west of the altar. For the last balls, you need to turn north from the platform and cast Revelio to see some rocks highlighted blue. Throw basic attacks at the rocks to destroy them and reveal the remaining balls. Once you’ve placed the balls on the last platform, you complete the Trial.
Merlin Trial #7: East of the West Hogwarts Valley Floo Flame
For the seventh Hogwarts Valley Merlin Trial, you must go east of the West Hogwarts Valley Floo Flame.
When you reach the spot and interact with the altar, you’ll see that the Trial is similar to the previous one, and you must follow the same logic to complete it. Therefore, you have three platforms and three groups of balls you must find. The first platform is on the top of the stairs west of the altar, and the closest balls are under the tower further to the west.
Place the balls on the platform using Accio. Another platform is found southwest of the altar, and for the closest balls, you have to open the gate to the right. Then, go through to see the balls next to many crates. The last platform is east of the altar, and you’ll need to destroy the fence standing in your way to get to it. Also, the remaining balls are in the space under the rock to the left of the last platform, and to get to them, you first have to burn the vines using Confringo or Incendio.
Merlin Trial #8: In Some Ruins
The next Merlin Trial in Hogwarts Valley is found in the ruins southwest of the previous puzzle you solved. It’s worth mentioning that in the same ruins, you can clear one of the Hogwarts Valley Ancient Magic Hotspots. For this puzzle, you must do the same as you did for Trial #5 and destroy nine balls using basic attacks. The balls are scattered all over the ruins, and you can easily spot them all if you get on your Broom, go southeast of the altar, and cast Revelio, like in the next image.
Merlin Trial #9: Northwest of the Keenbridge Hamlet
Next, go northwest of the Keenbridge hamlet to find another Trial puzzle near the river. Upon interacting with the altar, you’ll see that you have to solve another puzzle with stones and fireflies, just like you did for Trial #3.
The first two stones are found southwest of the altar, and two groups of fireflies are also southwest but a little further. For the last stone, head north of the altar, and the remaining fireflies are located downhill east of the stone. Cast Lumos next to the fireflies to make them follow you to the stones. When you bring the last group of fireflies to the last stone, you complete the Trial.
Merlin Trial #10: Next to the Keenbridge Floo Flame
The tenth Merlin Trial on the map above is in Keenbridge, right next to the hamlet’s Floo Flame. Now start the Trial and go southwest of the altar to find a boulder under a tree next to a fence. To solve the puzzle, you must push the boulder using Depulso into a hole northeast, across the bridge next to the Floo Flame.
You can also use Accio for some parts, but the bridge can be crossed only with Depulso because of the small slope. Once you get the boulder into the hole, the puzzle is solved.
Merlin Trial #11: Northeast of Keenbridge
The eleventh Hogwarts Valley Merlin puzzle can be solved northeast of Keenbridge. When you reach the spot, you should see the altar surrounded by stones. Interact with the altar, cast Revelio, and look around to see 5 of the stones highlighted in blue. The trick is to use Confringo to destroy the stones that get highlighted by Revelio.
Merlin Trial #12: Next to a Waterfall
To get to another challenge, you have to head to the west side of the area. Look for the altar high on a cliff next to a waterfall. To complete the Trial is fairly easy because all you have to do is jump on the three stones southeast of the altar without touching the ground.
Merlin Trial #13: In a Small Bandit Camp
Now, head northwest of the Northern South Sea Bog. You should see the altar in a Small Bandit Camp once you reach the spot. The puzzle can be solved by rebuilding three stone statues from the remaining pieces. So, use the Reparo spell on the remains scattered around the camp.
The first group of remains is next to the wooden stairs south of the altar. More remains can be found on the north side of the camp between the tents. For the last remains, you first need to burn the veins standing in your way west of the altar. If you have trouble finding them, don’t forget to use Revelio and highlight them.
Merlin Trial #14: Northwest of the Mine’s Eye Floo Flame
For the fourteenth Trial, go northwest of The Mine’s Eye Floo Flame. You have the exact location marked on our map. After finding the altar, interact with it to start the Trial, then turn to the west to see more of those stones you have to jump on. Start from the south and jump from stone to stone to solve the puzzle.
Merlin Trial #15: West of the Mine’s Eye Floo Flame
The next puzzle is very close west of The Mine’s Eye Floo Flame. Now start the Trial and head north of the altar to find a boulder you need to guide to a hole downhill. Push the boulder by getting behind it and casting Depulso.
Merlin Trial #16: Next to a Railroad
The last Merlin Trial in Hogwarts Valley is next to the railroad directly south of the previous altar. After reaching the sixteenth location pinpointed on the map above, begin the Trial and look for three torches you must light up. One torch is behind the barrels northeast of the altar; hence, you should first destroy the obstacles to have a clear shot because you’ll need to move fast later when you light the torch.
Another torch is on the other side of the railroad southwest of the altar. The last torch, which we suggest you start with, is located on the other side of the gap northwest of the altar.
You should get as close as possible, without falling, to the last torch and use Confirngo to light it. Then, light the one next to the railroad and finally the one to the northeast. Don’t forget you need to move fast to solve this puzzle.
