Core Grid Weapons

Weapon	Obtain	Notes
Ancient Ecke Sachs	Quest: Twin Elements Showdown Shop: Prestige Pendant ×1,000	Stacking four copies in your grid with 4★ Colossus Omega in Main/Support summons brings you to 88.4% critical hit chance. Later on, once you begin using 5★ Colossus, this will jump up to 98.8% crit chance.
Dagger of Bahamut Coda	Side Story: What Makes the Sky BlueTrade Bahamut Claw in the Shop Shop: Bahamut Weapons	Bahamut Weapons continue to be a core part of grids especially once it's fully forged and uncapped. Forge to Coda 4★ with materials from Proto Bahamut (Impossible) (Rank 101) Uncap to 5★ with materials from Ultimate Bahamut (Impossible) (Rank 130)
Sword of Michael (SSR)	Shop: Seraphic Weapons	This weapon should always be in a grid when fighting at an elemental advantage because of its 20% damage amplify. See Damage Formula for a detailed explanation of how the game calculates damage. Its 4★ upgrade into the Sword of Valorblaze, which increases its amplify from 20% to 23%, costs a sizeable amount of hard-to-get materials and should not be prioritized.
Scythe of Renunciation	Treasure Trade: Dark Opus Weapons Fire Quartz ×500 Axe Stone ×255 Shadow Substance ×5	This will be an anchor piece for all Omega Fire grids onwards into endgame content. This weapon should not be used until it is uncapped to 4★ and upgraded to lvl 120 as that is when you unlock its second weapon skill. 4★ Uncap Cost: Shadow Substance ×5 Silver Centrum ×5 Legendary Merit ×10 Supreme Merit ×100 Fire Urn ×30 Shiva Omega Anima ×10

Supplementary Weapons

Weapon	Obtain	Notes
Nilakantha	Raid: Shiva (Raid) Shop: Prestige Pendant ×6,000 (2 copies) Daily Point Shop (300 Points, 1 copy)	This weapon can introduce a boostable Stamina modifier to your grid before you can uncap your Scythe of Renunciation to 5★ at rank 170. This weapon is very expensive to purchase in the shop and should not be purchased until the rest of your grid is completed.
Al-Abad	Raid: Atum (Raid)	One of Fire's few charge attack related weapons, provides 400,000 Supplemental Damage to Fire allies' charge attacks as well as boosts Charge Attack Cap Up. Up to 2 are used with Attack awakening.

Cosmic Sword	Raid: Grand Order (Raid) (Share Chest) Treasure Trade: Cosmos Weapons Heavenly Horn x 30	This weapon comes uncapped to 3★ when obtained. Only one copy of a Cosmos Weapon is needed, feel free to fodder extras. Functions as filler until uncapped to 4★ which is locked behind materials accessed at rank 151 in Grand Order (Impossible). At 4★, the boost to the ATK and HP of equipped swords increases to 50% and gains a 1% boost to Damage Cap based on how many swords are equipped.
