I'm a shameless Harry Potter fan and I've created a character who I would like to be either an extremely skilled legilimen/occulmen or a metamorphmagus. I can't decide which one I want because I want my character to be able to speak to magical creatures too but I have scenarios where my character can disguise herself as another hogwarts student. Would it be too 'Mary-Sue ish' to give my character both abilities instead of choosing just one?
