Hypnos' Sword

Hypnos' Sword is a Light Blade in Golden Sun: The Lost Age.

Basic Description
Hypnos' Sword increases the wielder's Attack by 49 points. It can be bought for 2900 coins and sold for 2025 coins.

In the caves under Garoh is a ring of platforms, with an invisible platform in the center. Using Reveal will allow players to cross, and following the path will lead to a chest containing Hypnos' Sword. Being a Light Blade, it can be equipped by Isaac, Felix, Garet, Jenna, Ivan, and Piers.

Hypnos' Sword's Unleash effect is Moon Air. Moon Air converts all damage to Jupiter damage and attacks with an additional 18 damage points. Also, it may put the target to sleep. Visually, Moon Air resembles a normal strike with a cloud released on impact.

Analysis
Most likely, Hypnos' Sword will be given to Jenna. Felix will be able to equip the stronger Storm Brand, which can be picked up at Air's Rock. It serves as an effective replacement for the Pirate's Sword (should it still be in the party's inventory) as both their Unleashed powers can put the target to sleep. Hypnos' Sword may remain equipped to someone up to the battle with the Aqua Hydra.
