What spell is it to Become a real wizard forever if you are not a wizard?

In many fantasy contexts, there isn't a specific spell that guarantees someone can become a wizard forever if they aren't one already. Instead, the journey often involves extensive study, practice of magical arts, and sometimes a rite of passage or a transformative event. In some narratives, acquiring a powerful artifact or completing a quest may also lead to permanent wizard status. Ultimately, the specific spell or process can vary greatly depending on the fictional universe.
