Ultima Weapons are fabled weapons associated with Ultimate Bahamut. These weapons boost ATK and HP for characters that match a weapon specialty.

The first weapon stage is called Atma. Atma and Ultima weapon skills can be customized with Gauph Keys after its creation.

You must be at least rank 80 to craft these weapons. A free Atma Weapon can be obtained from the event What Makes the Sky Blue III: 000.

Multiple Ultima weapons cannot be equipped in the same grid. At 5★, Ultima weapons can be placed in the additional weapon slots of Party Set Extra.

List of Ultima Weapons

Step 1: Obtain a Rusted Weapon

The first step to creating an Ultima weapon is obtaining a level 75 Rusted Weapon. There are three ways of getting these: commonly from the Proto Bahamut raid, uncommonly from the Angel Halo dungeon, and by trading Renown Pendants for them at the Shop. If you run Angel Halo, it's recommended to run it on Very Hard.

A rusted weapon can be uncapped by combining 4 copies, but you can also buy Steel Brick square.jpg Steel Bricks from the Casino to fully uncap it.

Step 2: Create an Atma Weapon

To create an Atma weapon, you must first create a relic from a level 75 Rusted Weapon. To create a relic, go to the Shop > Weapon Series > Ultima Weapons > Atma Recollection, then look for the weapon type you wish to craft. In addition the following items are needed to create a single relic. These depend on the element you choose for your weapon:

After creating a relic, the following materials are required to upgrade the relic into an Atma weapon. These also vary depending on the element chosen (Dark requires both Water and Earth trial fragments; Light requires both Fire and Wind):

You can currently only obtain Ultima Core square.jpg Ultima Cores by hosting and clearing an Ultimate Bahamut raid of either difficulty for the first time, by trading in Ultima Unit square.jpg Ultima Units or Cloud Commendation at the Shop, or from the event What Makes the Sky Blue III: 000. Thus, you can have at most six Atma Weapons in your inventory. However, reducing an Atma weapon allows you to regain its core.

Step 3: Create an Ultima Weapon

An Atma weapon at level 100 and weapon skill level 10 is required to create an Ultima weapon. Note that increasing an Atma weapon's skill level is equivalent to that of a Bahamut Weapon. These materials are needed to forge an Atma weapon into an Ultima weapon, some of which correspond to the weapon's type and element.
