For determining the success or failure of actions and attacks, each unit is assigned an appropriately sized polyhedral die for its Action attribute, which it must roll against a set number determined by the difficulty of the act. When an attack successfully hits, the attacker rolls their weapon's Damage dice in the hopes of overcoming the target's Armor dice roll. Most infantry units are killed by having their Armor overcome once, while larger vehicles and structures are more resilient and may take multiple hits before being destroyed. At each stage, the die rolls can result in a variety of unintended consequences beyond simple success or failure, usually to amplify mayhem in extremely unlikely ways by power of irresistible "Koincidence."
