[Bugs] Superior Weapon Mastery Skill
 

Superior Weapon Mastery (10251) str+2, spd. +25%, P.atk. +376 and p.accuracy +3 when a sword, blunt, or spear weapon is equipped. Increases the number of possible targets during a spear attack. 50% chance of triggering Lightning Force during a critical attack. Additionally, there is a chance the re-use time of skills will reset or the duration double depending on your str.

As description, this skill has 50% chance of triggering Lightning Force during critical attack.

But when we test, even with normal attack without using skill or using skill but no critical, Lightning Force is still triggered.

Fixed, bad Russian translation :)
