Frost and cold
We write frost as:
Frost notation
Strength x Efficiency
Effects of frost
Hit
Attack = frost strength + 2d6
against
Defense = constitution + 2d6
The “defense” roll is completely unconscious; you do not have to concentrate on it, spend defenses, etc.
Evaluation
Multiply the difference between attack and defense by the efficiency of the frost:
Frost effect
Effect = difference x efficiency
