From Forbidden Arcana:
THE NULL WIZARD
The null wizard is an odd manifestation of magic. These Awakened, if you call them that, cannot
actually create anything magical. They are, however, talented in disrupting or redirecting magic.
How some individuals have Awakened this way
is a mystery, though one theory suggests that the
metahuman condition as a whole subconsciously perceives magical threats, and some manifest
this awareness as null wizards.
• Cannot use any of the following skills: Alchemy, Artificing, Binding, Ritual Spellcasting, or Spellcasting.
• Cannot astrally project.
• Gains Reflection metamagic for free (p.151,
Street Grimoire).
• Gains Spell Resistance quality for free
Does a Null Wizard require a magic rating, or are they unable to have a magic rating?
Chummer adds it on as a quality not as a priority option and Spell resistance states that you can't have a magic rating with the quality. And reflection uses the magic rating to calculate its effect. Would I have to make a mage of some sort and then apply Null Wizard after the fact, or just go with "Aware"?
