In this guide, you will find how to unlock CRUCIO (Dark Arts Unforgivable Curses) in Hogwarts Legacy.
CRUCIO is the first of three unforgivable curses in the game. To unlock it, you must progress far enough into the main story quests and complete the High Keep. After that, you will get an alpost from Sebastian and need to start Sebastian’s quest.
You’ll meet with Ominous and go down into Salazar Slytherin’s Scriptorium. Start at the entrance, and there will be some puzzle doors. To unlock these puzzle doors, look at symbols at the gate and determine what that symbol is.
Find the right mechanism, the one with the snake sitting on top of them and then move your left stick and the right stick to match up the symbols. It will open up the gates. Enter the room; you will find a blocked door, and bones will be laid on the inside floor. You need to do a conversation between Ominous and Sebastian, and you will learn the CRUCIO.
After that, finish the quest, and you will have access to CRUCIO. You cast it on your enemies, and it will cause agony.
