SirTapTap, I wish more games did stuff like #FinalFantasy Tactic's "Faith" stat. It's mostly a generic force multiplier for incoming magical healing/damage
But if your faith is 0, AKA your character does not trust/believe in the divine whatsoever...magic doesn't affect them. At all. Cannot be healed, or hurt by magic. Which is otherwise, by any other measure, completely real in this universe.
