Editing Autumn (section)

==The Core Rules ==
Autumn is based on a class and rank system to simply the diverse vehicles, soldiers, and equipment into a manageable (mostly) one roll system. All forces are classified under elements, all of which have innate statistics that are modified by the extensive trait system. These statistics are compared and rolled based on their relative values. 

Compare your score and the enemy's, using the difference to find the success threshold. 

Enemy skill is 4 higher: automatic failure
Enemy skill is 3 higher: 8+
Enemy skill is 2 higher: 7+
Enemy Skill is 1 higher: 6+
Enemy skill is equal   : 5+
Enemy skill is 1 lower : 4+
Enemy skill is 2 lower : 3+
Enemy skill is 3 lower : 2+
Enemy skill is 4 lower : automatic success

This is known as a ''rank roll'', and defines shooting and melee rolls.
