Sacred Guardian (Totally Rewritten) [-2]
You possess a holy power that allows you to harm monsters that would otherwise resist or ignore your attacks.
Musts: You must have a high concept representing some sort of celestial or divinely empowered status.
Skills Affected: Fists, Guns, Weapons.
Benefits: Holy Attacks. Your physical attacks satisfy Catches of "holy stuff".
Shatter the Immunity. You may take one point of Mental Stress, before rolling the attack, to allow a single attack to satisfy any Catch or Catches possessed by your opponent.
Does that look more balanced? Cheaper than ACAEBG, but per-attack, not per-scene.
