Creatures will follow this MP chart based on what kind of caster it is. FC for full casters, who act like full fledged wizards and clerics. SC for semi-casters, who act like warrior wizards or jack of all trades. PC for partial-casters, who act like a full fledged warrior with minor magic usage. You could also apply the PC to any monster who doesn’t have a MP if you want a source of mana in your game setting. Most MP will be rounded down and creatures will receive bonus MP on their caster modifier Int, Wis, or Cha [varies on creature] from the MP System page.
