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 5, so in order to inflict a level 1 critical, an attacker must deal 5 to 9 raw damage in the absence of weighting. Achieving ten raw damage can cause a level 2 critical, though the actual level of a critical will vary due to critical randomization. See also damage factor and armor.
