Longsword

The Longsword is a melee weapon in Xenoblade Chronicles X, used by the Striker, the Samurai Gunner, and finally the Duelist classes. Additionally, the characters Gwin, Frye, and Nagi use this weapon.

Overview
Longswords are popular due to their quick ability to gain from large numbers of enemies through their powerful area of effect Arts like Tornado Blade and True Stream Edge. They primarily use their stances, Offensive Stance and Defensive Stance, for the ability to act as either an offensive or a defensive weapon.

Ether Longswords are popular thanks to the combination of the Core Crusher and the arts Blossom Dance, Offensive Stance, and Ghostwalker (from Dual Guns) to do massive damage while dodging attacks, in a build known as the Ether Blossom Dance build.
