The Xylion Armor is an Armor-class piece of armor, which can be forged from Orihalcon in Golden Sun: The Lost Age and Golden Sun: Dark Dawn. Visually, it resembles yellow body armor, appearing similar to Erebus Armor.
 Basic Description by Game
The Xylion Armor increases the wearer's Defense by 50 points and the wearer's Attack by 12 points. It can be bought for 22500 coins and sold for 16875 coins.
In The Lost Age, the Xylion Armor is obtained by bringing an Orihalcon to Sunshine in Yallam, where there is a 20% chance of the Orihalcon being forged into the Xylion Armor. Xylion Armor can be worn by Isaac, Garet, Felix and Piers. In Dark Dawn, Xylion Armor is obtained by bringing Orihalcon to Obaba in Champa, who can forge the Orihalcon into Xylion Armor. It can be equipped by Matthew, Tyrell, and Eoleo.
In both Games, the Xylion Armor and the Demon Mail tie for the second-highest defense rating of any Armor, outdone only by the Valkyrie Mail. However, one can only obtain one Valkyrie Mail, whereas it is possible to have multiple copies of the Xylion Armor. Its high defense, combined with its bonus to attack, make it a very practical choice for an endgame party. In The Lost Age, it is perhaps only outdone by Mythril Clothes for warrior-type Adepts, because some players may prefer the Mythril Clothes' increased criticals to the Xylion Armor's increased attack.
