The Ends Petrify the Means Trophy in Hogwarts Legacy

Petrificus Totalus and Disillusionment, the spell that hides you, come with Secrets of the Restricted Section. Cast Disillusionment, sneak up behind an enemy and press when the prompt shows. Each enemy counts once: reloading and petrifying the same one again doesn't count. Bandit camps all over the map are full of targets. The Petrificus Totalus Mastery talent (level 22, Stealth) also catches the enemies standing nearby.
