A new update was recently released for Hogwarts Legacy and it seems to have included a rather controversial change that was not mentioned in the patch notes.
In a new post on the HarryPotterGame subreddit, it was revealed that the Unforgivable Curses are no longer usable in the boss fight against Cassandra Mason, a villain in the game. She was the original owner of The Haunted Hogsmeade Shop who lured people into entering it and getting inside a chest owned by a poltergeist named Fastidio and becoming trapped there. She was defeated by the player and gets taken to Azkaban.
Originally, players could use any of the three Unforgivable Curses on her. These are spells that are illegal to use in the Wizarding World, but very powerful. These are the Crucio which tortures the target, Imperio which controls the victim, and lastly Avada Kedavra, the Killing Curse. With the latest update, it seems it has been disabled for the fight and will have to defeat here with the basic spells the players have.
The patch notes did say that it resolved an issue that would crash the game if players used Avada Kedavra on Cassandra Mason at the start of the fight. It could be that the patch just made it impossible to use Unforgivable Curses altogether so it would not trigger the bug or it was triggered unknowingly. Some fans did not like the change because it took away the freedom that Hogwarts Legacy offered to players in playing.
Hogwarts Legacy is out now on PC, PS4, PS5, Xbox One, and Xbox Series X/S.
