According to Hogwarts Legacy lore, the legendary Arthurian wizard Merlin was once a member of the Slytherin house at the Hogwarts School of Witchcraft and Wizardry, and during that time he established a wide selection of extra-curricular activities for himself and his fellow Slytherins. These activities appear in Hogwarts Legacy as Merlin Trials; puzzles and challenges scattered about the map that test your spell-casting and puzzle-solving skills. One of the more challenging Merlin Trials is in the tiny village of Irondale, which is in the Feldcroft Region, close to where it borders Hogwarts Valley and the South Sea Bog.

How to complete the Merlin Trial in IrondaleThe Irondale Merlin Trial is in a scarecrow-guarded pumpkin patch on the mountainside on the northwest side of the village. Sprinkle some Mallowsweet Leaves on the Merlin Trial marker, then start looking for three sets of pillars with large stone balls (or orbs) on top of them.
