Spiru-Dynamics
There is a divine law is known as spiru-dynamics. What this means is the output of power from divine magic can never be greater than the input used to manifest the effect. This really only has one applicable scenario, and that is the healing of Spirit. While incantations can heal and restore Body points and even Mind point to produce numbers greater than the cost of the incantation, this is only due to the inequality of types of energies transfered. For example, the treat minor wounds incantation costs 2 Spirit but could potentially produce 4 Body points in return. This also true for treat mind.
Again, while all of these healing and restoration spells are useful, the law of spiru-dynamics limits the amount of healing to Spirit that can be produce to the equivalent of the cost put into the incantation. Using again treat spirit as an example, the incantation heals Spirit on a d4; however, as a two-point cost, the maximum restoration to anyone's Spirit is two points. Granted, the d4 is a statistical measure and the roll indicates that on a raw 2, 3, or 4 the amount healed is the maximum two points, but this divine law prevents no more than two points to be healed for this incantation. To clarify, this is not just the spells in the examples, but also restore spirit and any other incantations that heal Spirit points.
