This is one’s innate resistance to Magick, and is similar in nature to that immunity which is provided by Technological Aptitude. (In fact, a creature with both faculties simply adds the two together, when Magic is directed against his or her person.) Unlike Technological Aptitude, however, innate resistance to Magic does not affect one’s own use of items or spells.
A final caveat: Armor, Background, Race, Technological Therapeutics and Magick can modify any or all of these resistances.
