This guide will let you know how to find & open the Entrance To The Hall Of Herodiana in Hogwarts Legacy.
This one is a side quest. The first thing you will need to do is follow the objective marker, and it will take you straight to the actual location. Go to the hall and you will find a strange button on the wall. You need the Depulso spell to push the button. So aim at the button and use the Depulso to press the button to reveal the entrance.
