Hogwarts Legacy Marunweem Lake Merlin Trials are puzzles you can solve while exploring the southeastern lake area of the video game published by Warner Bros Games. If you’re a completionist, it’s important to know that if you find and solve all Merlin Trials in Hogwarts Legacy, you unlock Merlin’s Beard! Trophy/Achievement.
By solving multiple Trials, you also complete Challenges that increase your inventory size, allowing you to carry more gear. However, you’ll first have to complete the Trials Of Merlin main quest, then obtain some Mallowsweet Leaves, and only after can you worry about the Merlin Trials.
If you are wondering how to get Mallowsweet Leaves, note that the fastest way is to grow them in the Room of Requirement. Of course, you’ll need the Mallowsweet Seed Recipe, which can be bought in Hogsmeade from the Magic Neep shop.
Where To Find the Four Marunweem Lake Merlin Trials in Hogwarts Legacy
To find the Merlin Trials in the Marunweem Lake area, make sure you use our map below. As you can see, they are scattered all around the area. Here is where to find them in the game.
Merlin Trial #1: Southeast of the Coastal Mine Floo Flame
The first Marunweem Lake Merlin Trial altar is found on the east side of the region, and you can quickly get to it by fast-traveling to the Coastal Mine Floo Flame and then heading southeast. Keep an eye on your minimap because the altar will appear if you get close enough.
Once you reach the first location on the map above, interact with the altar and cast Revelio to spot three stones. One stone is northeast of the altar, another southeast, and the last is on the cliff behind the large tree southwest.
As you can see, the stones are made of 2 parts, each with symbols on them. To solve the puzzle, you must go to each stone and use the Flipendo spell to match the symbols on the top parts and with those on the bottom.
Keep in mind that you can flip only the top parts. Also, your position toward the stones matters for the direction in which the top pieces will get flipped. Now, practice a little with Flipendo on the stones to better understand how it works and solve the puzzle.
Merlin Trial #2: Next to Some Ruins
The next Marunweem Lake Merlin Trial altar is next to some ruins east of the Marunweem Lake Floo Flame. Upon getting to the altar, start the Trial and go to the round boulder in the ruins because you’ll need to use Depulso on it to guide it to the hole northeast, across the bridge. However, a closed gate will stand in your way, and to open it, you have to cast Depulso at the mechanism next to it.
Merlin Trial #3: By the Water
The third Hogwarts Legacy Merlin Trial in Marunweem Lake is by the water west of the Marunweem Floo Flame. To solve the puzzle, you must interact with the altar and then turn west to see some stones. To continue, jump from stone to stone, starting with the one to the southwest. When you reach the last stone without touching the ground or water, you complete the Trial.
Merlin Trial #4: In the Ruins South of the Marunweem Ruins Floo Flame
For the last Marunweem Lake Merlin puzzle, you have to head to the ruins south of the Marunweem Ruins Floo Flame in the southwestern corner of the region. Now start the Trial, then cast Revelio to see three stones with diamond-shaped holes around the altar.
One stone is in front of the wall west of the altar, another next to some barrels northeast, and the last next to the pillar southeast. You also need to find three groups of green fireflies. You’ve probably figured it out, right? You must bring the fireflies to the stones to solve the puzzle.
But remember that a stone can’t contain more than one group of fireflies. To see two groups of fireflies, you have to turn northeast of the altar, and for the third, look southeast, outside of the ruins. Don’t worry; the fireflies are easy to spot because of their green glow. Now, to make the fireflies follow you back to the stones, you must cast Lumos near them.
