This guide will let you know how to open Treasure Vault East Of Phoenix Mountain Cave in Hogwarts Legacy.
You will first need to use your spell on the pole-like structure until the door opens. After opening one side, use the Arresto momentum on them.
After getting inside, you’ll be greeted with a chess game; you need to have the transform spell and then use it on the chair. Pick it up and drop it right there. Then you will get the treasure.
