During character creation, one of my players realized he could do the following:
He took a B priority on Metatype, and be a Human with 7 points of Special Attributes.
He split his points as 1 Edge, and 6 Resonance.
He then took an A priority on Magic or Resonance, to have Magic 6.
That's when we realized that we couldn't find anywhere a mention of the usual "you can't have Magic and Resonance, impossible, nada".
Did we miss something? Is it written somewhere that we haven't found, or are you supposed to know it from previous editions?
