Secret Art: Titan Blade

You greatly increase the size and weight of your weapons, then slam them down in a direction. You make a melee Heavy attack against all enemies in a 15ft wide line up to the range. On damage, a target is knocked prone.

After the initial hit, a shockwave follows. You make another Heavy attack against any enemy still in the original line’s range. This second attack has the Sure Hit and Full Pierce qualities against a prone target.
