I've been playing Hogwarts Legacy for a month and haven't completed the game. There are so many path-specific conversation options, I can choose not to learn unforgivable curses. Given the fact that Sebastian Sallow's uncle
does not want you and Sebastian to use unforgivable curses after Sebastian used Imperio on the goblin to protect his younger sister,
Will learning unforgivable curses (and using them) lead you to become a dark wizard or something along the same lines?
So, if there is more than one ending, it would be helpful if anyone could tell me what I need to do to cause the branching, other than learning unforgivable curses (such as picking a good-ish option in conversation?)
