How does Lunar soak work?
In the Lunar book, we learn that a Lunar Exalted cannot have a natural soak (i.e., soak gained from Stamina, Charms, and Beastman-form Gifts) higher than 12L/12B. [Lunars, 127] Any points of natural soak above that amount “spill over” and allow the Lunar to totally ignore weak attacks. The Player’s Guide refers to this as “hardness”; Power Combat changes many soak Charms to provide hardness.
