Cool is all about how you react to situations, will you be scared and run away or will you keep your cool.
This is the character’s natural ability to negate the effects of shock, severe wounding and fear. The higher the amount the character has in cool the better the chance he or she has of not succumbing to their effects.
All opponents will have a Fear Factor (F.F.), this F.F. acts as a modifier against a PC or NPC’s cool. In certain situations the Guide may require players to roll their characters cool. (See also the section Cool Rolls for further information).
