Tieflings are able to use a wide range of magic. Different aspects are determined by a tiefling's heritage, which is displayed primarily by their physical traits. The skin tone of a tiefling is the most reliable indicator of heritage and magical capability.

(No, I'm not going to list all the different subraces and ancestors from MToF. We can discuss that stuff over DMs)
