Sagittarius Bow

The Sagittarius Bow is a Bow-class Artifact weapon available in Golden Sun: Dark Dawn. It is notable for being the strongest weapon of its class.

Basic Description
The Sagittarius Bow increases the wielder's Attack by 170 points. It can be sold for 21750 coins and subsequently re-bought for 29000 coins.

To obtain the Sagittarius Bow, the player must explore the depths of Crossbone Isle and find the room with a pirate skeleton surrounded by several treasure chests. One of these chests contains a Worn Bow. Bring this item to Obaba in Champa and she will re-forge it into the Sagittarius Bow, and give it to the player free of charge. The Sagittarius Bow has three Unleashes: Triple Burst, Star Dust, and Comet Burst. Triple Burst is a Jupiter-based Unleash that does 80% more damage than a standard attack. Star Dust is a Mars-based Unleash that does 40% more damage than a standard attack, and may hit up to three adjacent targets. Blue Comet is a Mercury-based unleash that has a guaranteed multiplier of 2.2.

Analysis
The Sagittarius Bow is one of the strongest weapons available to Karis and Amiti, but is outclassed in terms of Attack rating by the Tisiphone Edge or Lachesis Rule. However, it has an edge in terms of Unleashes. Both the Tisiphone Edge and Lachesis' Rule have four Unleashes to choose from, while the Sagittarius Bow only has three. Thus, Blue Comet is statistically more likely to appear than either the Tisiphone Edge's or the Lachesis' Rule's main Unleashes. The Sagittarius Bow's Unleashes do an overall average of 1.8 times the normal damage, ensuring a relatively high, yet steady amount of damage.

Also, the Sagittarius Bow possesses one of the strongest Mercury-based Unleashes in the game in Blue Comet. Thus, Amiti can very easily increase the Unleash's Power with his own naturally high Mercury Power.
