Hunter's Sword

A Hunter's Sword (Hunter Sword in the Japanese version) is a common Light Blade-class weapon available throughout the Golden Sun series.

Basic description by game
A Hunter's Sword increases the wielder's attack by 28 points. As a common item, it can be repeatedly bought for 520 coins each and can be sold for 390 coins each. In the original Golden Sun, Hunter Swords can be bought in the towns of Bilibin, Imil, and Kolima, and can be equipped by Isaac, Garet, and Ivan. In Golden Sun: The Lost Age, it can be bought in the towns Alhafra and Garoh, and can be equipped by Felix, Jenna, and Piers.

In Golden Sun: Dark Dawn, due to changes to the Unleash system, the Hunter's Sword gains two Unleashes: Gale Force and Critical Strike. Gale Force is deals damage equivalent to the wielder's physical attack times 1.3, and then modifies the damage based on the wielder's Jupiter Power and the target's Jupiter resistance. Critical Strike deals damage equivalent to the wielder's physical attack times 1.5. Hunter's Swords can be bought in the towns of Harapa and Kaocho, and can be equipped by Matthew, Tyrell, Karis, Amiti, Eoleo, and Himi.

Analysis
In Golden Sun when it can be first bought in Bilibin, it is only slightly stronger than the  Battle Axe which can be bought as early as in the earlier town of  Vault, but it is practically twice as expensive, and yet it is also  only half as expensive as the strongest weapon in the vendors at that  point, Broad Swords. This severely limits its practical usability. Since Ivan's strongest weapon by the time he enters Bilibin can be the Magic Rod which still has a good deal less Attack than a  Hunter's Sword, it might have worked out to buy one for him, but also  available at Bilibin's Artifacts menu is the Witch's Wand, which is  stronger and better for Ivan to wield than the Hunter's Sword because it  has an Unleash effect that may inflict the Stun status effect.

In Golden Sun: The Lost Age, much of the game's focus is on completing puzzles in the dungeon-style locations that provide as rewards weapon artifacts far superior to commonly bought weapons and even weapon artifacts that can normally be bought in vendors, so you will most likely not want to buy and equip this weapon because you will have very easily found superior weapon artifacts such as Themis' Axe, Pirate's Sword, and Blow Mace before you even get to the towns that sell Hunter's Swords.

In Golden Sun: Dark Dawn, the Hunter's Sword will most likely be outclassed as a weapon by the stronger artifacts the player is able to acquire. Thus, it is not likely to see much use, as weapons such as Themis' Axe, the Elven Rapier and the Blow Mace can all be acquired by that point in the game.
