While Hogwarts Legacy doesn’t feature controls to crouch anytime you want, you can conceal yourself and keep close to the ground while the Disillusionment charm is active. This charm is also known as the invisibility spell, which you’ll learn from Sebastian Sallow early on in the game.

Once unlocked, you can use this spell to sneak into enemy camps and freeze the enemies with the Petrificus Totalus spell. Apart from the charm, you can also use the Invisibility Potion to hide from the enemies and sneak around.
