From the discussion in another thread...
Minor Magic [-0]: You are either a budding apprentice, a late bloomer, or otherwise have a very minor talent for magic. While not capable of true Evocation or Thaumaturgy, you can tag your high concept once per scene without spending a fate point, to perform very minor magical feats. You must have an aspect related to your magical talent, such as I DIDN'T KNOW I COULD DO THAT or BUDDING PYROMANCER, and may be subject to compels when your magical talent gets out of your control. With time, effort, and/or instruction, you may be able to upgrade to Channeling, Rituals, Evocation, or Thaumaturgy (spending the appropriate refresh). If so whichever full spell casting power you take replaces this power.
