Swift Sword

The Swift Sword is a Light Blade found in both Golden Sun games. Being a Light Blade, it can be equipped by Isaac, Felix, Garet, Jenna, Ivan and Piers. It increases the wielder’s attack by 104 and their Wind power by 10. It can be bought in Lalivero (in Golden Sun) and Shaman Village (in The Lost Age) for 9400 coins and sold for 7050 coins.

The Swift Sword's Unleash effect is Sonic Smash (Sonic Slash in Japan), which converts all damage to Jupiter damage. Although normally Sonic Smash doesn’t increase attack power, it occasionally does three times the normal amount of damage. Visually, Sonic Smash resembles the attacker rushing up and hitting the target, with small shockwaves released on impact. Normally the attacker only hits the target once, but when Sonic Smash does triple damage the target is hit three times.

In Golden Sun, the Swift Sword can overpower even the Gaia Blade when Sonic Smash does triple damage. The Swift Sword is best placed into Ivan's hands, since it boosts his already high Jupiter power and Sonic Smash does Jupiter damage. In The Lost Age, the Swift Sword is unavailable until late in the game, and so players will probably have already acquired stronger and more reliable weapons.
