Critical

CRIT
Critical Hit Rate: Your critical hit rating, which increase damage by 200%. Offensive Skills do not take CRIT into account except for a few exceptions like Focused Arrow Strike.

The critical rate being displayed in the status window isn't the true value which is applied against monsters. The "status crit" is calculated by dividing current LUK by 3 and adding the crit bonuses from equips/cards. The real crit rate is a little different. Formula : LUK*0.3 + bonuses.

Critical Hit Rate is doubled when you use Katar type weapon.

Because of difficulty of acquiring CRIT without sacrificing lots of other stats or useful cards/gears, it is recommended it is used on classes that naturally has fast ASPD one way or another.
