Helm of Urktot is a main quest that you will come across quite early in your adventure of the Hogwarts world. The quest requires you to go into the Witch’s cave. The cave is named the Collector’s cave. You need to find the Witch’s Tomb and retrieve the helmet.
During the quest, you will find several puzzles that will block your progress. Like much of the game, the puzzles unlock doors and progress deeper. There is a title of three-door puzzles.
All of the Witch door puzzles in Hogwarts Legacy can be opened with the help of the Lumos spells. All of the doors you will encounter will have the spot where moths need to go. The moths will be scattered around the dungeon. You need to attract each moth/butterfly with the help of the Lumos spell and then lead them to the door.
Two other spells you will need to use to solve the moth/butterfly puzzle are Accio and Depulso. With that revealed, you can watch our video to solve the Witch/Collercor’s cave puzzle in Hogwarts Legacy.
