Dagger of Bahamut Nova	Side Story: What Makes the Sky BlueTrade Bahamut Claw in the Shop Shop: Bahamut Weapons	Bahamut Weapons are very strong Normal modifiers and can be used in any element grid. Once forged further, they will boost two races depending on the weapon type. Dagger of Bahamut Coda boosts Human and Erune characters which are the most common races in the game. Sword of Bahamut Coda is the second common choice which boosts Humans and Draph characters. More Bahamut Weapons can be forged later to support different team compositions.
Gauntlet of Uriel (SR)	Shop: Seraphic Weapons	This weapon should always be in a grid when fighting at an elemental advantage because of its 10% damage amplify even at 0★. See Damage Formula for a detailed explanation of how the game calculates damage.
