Overview

Marth does a forward vertical slash from top to bottom with his sword, doing 7% damage on the base of the sword and 10% with the tip. Although it has low knockback if hit on its base, it has KOing potential at around 150% when hit on the tip, and can KO earlier when used near the edges of the stage. Hits with an arc which covers his entire front body within frames 6 to 8. It is useful move for spacing, edgeguarding, and aerial approach tool due to its long-ranged disjointed hitbox. However, it has 16 frames of landing lag making it unsafe to land with this attack. It also has low hitbox duration, making it require precise timing to consistently space with it.
