There are a total of 95 Merlin Trials in the Hogwarts Legacy. All of them can be found in the Highlands. They are simple puzzles that in most cases require the use of one of the spells you can learn to achieve a certain goal. To unlock Merlin Trials you must complete the main quest "Trials of Merlin".
To start the trial you need to approach the stone circle and interact with it. To be able to do this you need the Mallowsweet Leaf. You can grow it yourself in the Room of Requirement. Mallowsweet seeds can be purchased from The Magic Neep. They can be grown in pots of any size.
