Oxidals get three extra points in their Advantages if they don't take magic, right?

"Oxidals aren't attuned to any magical element so they don't get any points to spend on powers. Instead they have to spend their advantage points to get access to magic. On the bright side, Oxidals can't be manipulated by Spirit magic or be detected by Ashan Third Eye and Erdevar Magical Sense."

They start with three extra anyway but if you want to use magic you have to use your Advantage points since you don't get any magic points.
