Diablo 4 is the kind of game that benefits from a keyboard and mouse and with a slight tweak to the controls, using skills can become even more efficient. Given how important movement abilities are in an action-RPG, it’s crucial that players looking to optimize their builds correctly assign their powers to buttons that make sense. This can be made a little easier on a controller thanks to various shortcuts, but when it comes to a mouse and keyboard, having all those separate options can be intimidating for newcomers.
