An attacking combatant rolls percentile dice, adds his or her OB to the total, adds modifiers, and subtracts the defender's DB. The total is then applied to a table for the attacker's weapon. The attack total is cross-indexed with the type of armor (if any) worn by the defender and the result will be a number of concussion hits dealt, which are then subtracted from the defender's running total. If sufficient hits are dealt, the defender may go unconscious, but death seldom results purely from concussion hit damage.
