Critical hit

• A critical hit occurs randomly (with a 9% chance, subject to certain modifiers) when hitting with a ranged or melee attack, as well as when casting spells as of August 12, 2009. A critical hit will always hit the monster, regardless of your actual hit chance. It also increases the amount of damage you deal to your opponent. Specifically, it doubles the weapon power component of the damage:

 weapon damage = (a term based on your stats vs. monster's defense)
                 + Main weapon damage × crit × tsfactor            
                 + Offhand weapon damage
                 + bonus melee damage                              
                 + bonus elemental damage

 spell damage = (crit × base spell damage + bonus absolute spell damage) × (1 + bonus percent spell damage)

Where

• crit is 1 for a normal hit, and 2 for a critical hit, and
• tsfactor is 1 for a normal attack, 2 for a Thrust-Smack, and 3 for a Lunging Thrust-Smack.
• Weapon damage is (10%-20% of weapon power + 0 to 1), or 1 if barehanded.

Monster Critical Hits

Monsters can critical hit too -- but a monster critical hit doesn't cause you any extra damage; it just succeeds in hitting when it otherwise would have missed. Monster critical hits, like monster fumbles, occur with a 1/22 (4.5%) chance per round. Thus, the total chance of abnormal monster behavior in any given round is 1/11, the same as player critical hits.
