Mythril Silver

Mythril Silver is advanced forgeable material in Golden Sun: The Lost Age. It is described as "Legendary dwarven metal" (this solidifies the apparent fact that the residents of Loho, where one piece of Mythril Silver can be found, are a race of dwarves). It is found in various areas after the Wings of Anemos are acquired, such as in Loho and Yampi Desert Cave, and can also be dropped very rarely from a Soul Army in the same cave (fell it with Jupiter Djinni to increase drop rate by four times). Being an Artifact, it can be sold and later repurchased. It can be bought for 2000 coins and sold for 1500 coins. It can be forged into the following highly powerful equipment:

Analysis
Several pieces of the Mythril Silver-forged equipment are among the best equipment in the game. The Mythril Clothes are a slightly-toned down Valkyrie Mail, but it can be worn by any Adept, the Mythril Helm is an ideal piece of headwear for offensive warrior Adepts, and the Psychic Circlet has a very high PP recovery rate (sure to be useful to any Psynergy-centered Adept). However, the Levatine can be outperformed by weapons with unleashes that multiply attack power, and the Mythril Armlet is ultimately an inferior form of the Riot Gloves.
