If the character is stealthy or behind the opponent's back, he can deal a fatal blow to an enemy. The character must make a DEX test (including bonus) and must be greater than or equal to 20 to instantly eliminate a target. If the target is a boss or mini-boss, he takes double weapon damage. If the result is 15 or more, it deals normal weapon damage.
