Mii Swordfighter gets down on one knee and lays their blade across their leg; they then draw a whetstone and stroke it across the blade, sharpening it. The move increases Mii Swordfighter's attack power for the next twenty seconds, allowing them to deal 2% more damage with all of their attacks. If the button is pressed again just as the red glow appears from the whetstone's stroke across the sword, hot sparks will fly off of the blade and spread in front of Mii Swordfighter, dealing damage to nearby opponents.
