If there was ever an essential class that players could choose just one from classic fantasy worlds, it would have to be wizards, right? They are some of the most iconic and imposing characters and have formed a core part of the genre ever since Gandalf the Gray was first introduced in Tolkien's The Lords of the Rings. Since then, wizards have flooded the genre, and naturally made their way into open-world video games where players can actually pick them as their go-to choice to play.
