As you make your way through Hogwarts castle, you’ll eventually stumble upon Eye Chests. These can be randomly found throughout the grounds, although it’s not immediately clear how to open them. Get too close, and they’ll lock down tight – blocking your attempts to pick the lock until you retreat out of sight. And try as you might, no spells seem to have any effect on Eye Chests.
Instead, you’ll need to cast a spell on yourself to open Eye Chests in Hogwarts Legacy. After learning the Disillusionment spell (which occurs during the Secrets of the Restricted Section quest), you’ll need to cast the spell on yourself while out of sight from an Eye Chest. Then, with the spell cast, you can simply walk up to Eye Chests and unlock them.
Keep in mind that you’ll likely find several Eye Chests before learning the Disillusionment spell – so commit their location to memory and head back once you’ve added the spell to your arsenal.
Another option is to use Invisibility Potions instead of the Disillusionment spell. We’d recommend against this, however, as those potions have better uses. Just be patient, and once you’ve unlocked the proper spell, retrace your steps and unlock the Eye Chests.
