A critical divisor or crit divisor refers to a property of armor that determines the rank of a critical when struck. The critical divisor for an unarmored opponent is 3, so in order to inflict a level 1 critical, an attacker must deal 3 to 5 raw damage. Achieving six raw damage will cause a level 2 critical, though the actual level of a critical will vary due to critical randomization.
