Levatine

A Levatine is a Long Sword-class weapon Artifact available in Golden Sun: The Lost Age. It is only bought randomly by bringing a Mythril Silver forgeable material to the blacksmith in Yallam so that he may create one of several possible, randomly determined items from it, including this one. Being a Long Sword-class weapon, the Levatine can be equipped on warrior-style Adepts, namely Felix, Piers, Isaac, and Garet. Its buy value is 19700 coins and its sell value is 14550.

The Levatine increases the wielder's base Attack rating by 173 points. Its Unleash effect is Radiant Fire, with the standard base activation rate of 35%, which is a physical attack with an additional 66 points of damage added, and then the resulting damage is either increased or decreased based on how the user's Mars power measures against the target's Mars resistance. In addition, the effect may ignore half of the target's Defense rating during the attack, which increases the damage done. Radiant Fire visually resembles the wielder’s attack explode into a series of circular fire patterns.

A Levatine is technically one of the game's best weapons because it is about equal to the Fire Brand, and the two are the strongest Mars-based weapons. While the Levatine will always do enhanced damage because of its Unleash's side effect, the Fire Brand is a pure-element weapon whose Unleash may put the target to Sleep, so if you have both weapons deciding between one over the other is a matter of personal taste. However, they are not the actual best weapons because weapons of other elements such as the Tisiphone Edge, Excalibur, and Masamune can outright multiply the damage they inflict with their Unleashes, so while the Levatine and Fire Brand are solid for a Mars Adept warrior like Garet to wield, it might be better for him to use one of the above three weapons for potentially much stronger damage.

The Levatine is often compared to the Mythril Blade, the other weapon artifact that can be forged from a Mythril Silver, and the more-common-to-forge Mythril Blade has lower power levels and has an Unleash that is of the Mercury element and Seals the target's Psynergy. Many players would identify the Levatine as a better weapon, but to be fair that would only be the unshakable truth if it's a Venus or Mars Adept who is considering equipping one of the two weapons. The Mythril Blade is a strong, solid weapon for the Mercury Adept warrior Piers to equip just as the Levatine is a solid weapon for the Mars Adept warrior Garet.
