Orihalcon

Orihalcon is the most powerful forgeable material in Golden Sun: The Lost Age. It is described as "An ore of great power". Because it is an Artifact, it can be sold and later repurchased. It can be bought for 4000 coins and sold for 3000 coins.

The Lost Age
Orihalcon can be obtained in the following areas:


 * A chest in Anemos Inner Sanctum
 * Mars Lighthouse
 * From an transfer-data event during the first departure from Contigo after The Reunion, assuming Isaac's party rescued Hammet from Dodonpa in Golden Sun.
 * A chest in Yampi Desert Cave

It can also be dropped (extremely rarely) from a Sky Dragon in Anemos Inner Sanctum (fell it with Jupiter Djinn to increase drop rate by four times).

Dark Dawn
Orihalcon can be obtained in three chests:


 * Champa, Obaba's Storeroom B1F (entry through B2F requires Briggs' Key, then access B1F through usage of Thermal Psynergy)
 * Crossbone Isle, Level Three Lower Floor, northern chest
 * Crossbone Isle, Level Final Lower Floor, middle of room

Also, Nightmares in the Otka Island labyrinth drop Orihalcon. Its drop rate is 1/256, which improves to 1/64 when a Venus Djinni deals the killing blow.

Analysis
Because of the power of the equipment forged from it, Orihalcon is a desirable and practical item that many players seek multiple copies of. From it can be forged Excalibur, which is the second best weapon in the game because it can triple the user's damage output. On average, the Sol Blade will deal more damage than Excalibur, but only one Sol Blade can be acquired so multiple copies of Excalibur are desirable for the three remaining warrior-style Adepts. An Orihalcon can also yield the Cosmos Shield, which is the best hand-armor available because of its defense and resistance boosts. The 40-point Mars-power boost of the other hand-mounted armour, the Big Bang Gloves, is a great asset to any Adept using Mars-aligned abilities, and the Nebula Wand's PP restoration and Mercury-alignment make it arguably the best weapon for Mia to equip. The Millenium Helm and Xylion Armor are strong defensive items with big statistical buffs. Orihalcon's only item that is undesirable is the Stellar Axe, because though it is powerful in its own right, it is inferior in every way to Excalibur.

Cultural Allusions
The material "Orichalcum" is a brass/gold-like metal mentioned in several ancient texts, such as Plato's account of the mythological civilization of Atlantis.
