You know how Scorch Wheel and Mirror Buster have a white bar on top of the normal one that displays how much time an action has before it ends, right? I wanted to suggest using that same aesthetic in reverse for Pharaoh Shot. Make the white bar rise to show how much the weapon has charged. Sure, you know when it's at maximum when it flashes, but it's good to know when that's going to happen in the middle of a fight.
