Love the story so far! Keep up the good work! Also, some ideas for cursed spirits for the MC: one to act as an inventory/storage (so he can take everything in the Room of Lost Things in the Room of Requirements of Hogwarts), one that can help protect his mind and help him attack/read the minds of others, one that can help him go places/teleport/shadow travel (like Dumbledore's phoenix that cannot be stopped by wards), one that can help him copy the knowledge/books of things/people nearby, one that can hide him/hide his presence completely (both physically and magically), one that can purify/devour Negative Magical energy and/or convert it into regular Magical Energy, one that can grant him regeneration/recovery, one that can hypnotize other people/beasts, one that can possess/enthrall/control other people, and one that can track people from far away.
