Trivia
Apparently this skill has a unique attack animation. The character starts to perform a regular slash, but brings the sword the equivalent of about 8 inches lower, then performs a swift right-to-left slash at this lowered height. Presumably, this would be striking the opponent's legs, although it sill works against things which lack them, and the attack hits somewhat higher than a proper hamstring would.
