Critical hits occur as a result of an accuracy roll that results in all three dice landing on the same number (three of a kind). The exception to this is the 1/1/1 roll, which is called a critical miss. All other critical hits will automatically hit, regardless of whether the attacker's accuracy was high enough to overcome the target's evasion.
Critical hits will cause the relevant damage rolls to deal full damage in addition to their normal damage.
Critical hit chance[]
The standard critical hit chance is 2.31%, but some abilities have keywords that affect critical hit chance.
