Sword of Dusk

The Sword of Dusk is a Long Sword-class Artifact weapon introduced and available in Golden Sun: Dark Dawn. It resembles a type of broadsword with a purplish-black colored middlepart of the blade and a golden hilt.

Basic Description
The Sword of Dusk raises the wielder's attack by 100 points. It can be sold for 8625 coins and subsequently re-bought for 11500 coins.

The Sword of Dusk is found in a treasure chest inside of Teppe Ruins and can be equipped by Matthew and Tyrell. The Sword of Dusk features three Unleashes: Critical Strike which deals increased damage, resembled by a huge cutting mark. Spin Strike propels the Adept towards the opposition and releases a shockwave to hit multiple targets. Last learned is the Sunset Burst, its signature skill. The blade begins to glow like a sun during the user's forward leap and detonates in sunset resembling explosions upon contact with the target.

Analysis
As soon as it is available, this sword is a powerful weapon that will be useful no matter which Adept receives it. This is mainly as its last Unleash is Mars-based and comes with a powerful damage multiplier at this point in the game, so it will probably end up in the hands of Tyrell whose innate Mars power bolsters the strength of its Sunset Burst even further. When activated, it may also cause Delusion at the target which is a minor bonus as most enemies will fall shortly after this attack. Thanks to the high attack increase, it will remain useful throughout Morgal, and can later be given to Matthew after Tyrell acquires the Giant Axe. Once the party gains access to the ship, the Sword of Dusk gets outclassed rapidly by other weapons found in certain water spots and upcoming Vendor artifacts.
