How To Complete Acting On Instinct in Hogwarts Legacy
As you approach Natty, you will see Professor Onai, Natty’s mother, concerned about her health and asks if she is up for a visitor. Natsai reassures her mother that she is fine and wants to see you. Professor Onai warns Natty not to overdo it.
When you speak with Natty, she will be happy to see you, and you’ll start discussing her recent injury. When you apologize for your role in it, Natsai will tell you not to feel guilty because she chose to protect you.
She then realizes that her father’s sacrifice was also based on instinct and reassures you are not to blame for her injuries. Then, you’ll discuss the battle at Hogwarts and the defeat of your enemies, including the death of Rookwood and the capture of Harlow.
Natsai expresses gratitude for your friendship and its important role in her life. You both acknowledge the importance of your teamwork and the safety it has brought. Finally, you both express appreciation for each other’s company and the visit, which will complete the Acting On Instinct Relationship Quest in Hogwarts Legacy.
