Ultima Weapons are fabled weapons associated with Ultimate Bahamut. These weapons boost ATK and HP for characters that match a weapon specialty, and at their highest level of crafting have three weapon skills that can be customised with Gauph Keys to the user's needs.

The first weapon stage is called Atma. The first skill offers a selection of modifiers including ATK, HP, Stamina, Enmity, Critical Hit Rate, and Attack Rate boosts.

The next crafting stage develops the weapon into a true Ultima weapon. The second skill can be one of several Damage Cap boosts, and can only be obtained with drops from the Impossible version of the Ultimate Bahamut raid. The third skill, only obtainable with drops from Rage of Super Ultimate Bahamut, offers further specialist skill choices for high-level players.

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

See: Weapon Lists/Ultima

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 Bricks from the Casino to fully uncap it.

Step 2: Create an Atma Weapon

What Element Should I Make the Atma Weapon In?

See also: Advanced Grids#5★ Ultima Weapons

As all skills on Atma and Ultima weapons affect allies of any element, the element choice is not especially important. Any Atma/Ultima weapon can be used in any grid, so the element only matters for main weapon or auxiliary weapon purposes. And although Ultima weapons become very powerful at 5★, their charge attacks remain old and outdated. As a result, most Ultima weapons are only used as a "last resort" main weapon when an element lacks strong farmable weapons to use with a certain class, or sometimes to free up grid space in a setup that won't charge attack.

When deciding on which Ultima Weapon type to make, it's always best to consider what would benefit the teams that you use the most. Each player has different teams and characters available to them so there is no single "correct" choice.

The element selected for the weapon is largely irrelevant as Ultima Weapons are rarely used as main weapons. If you need some general guidance, refer to the chart below.

Relics

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:

• 
  Low Orb
  • Fire Orb
  • Water Orb
  • Earth Orb
  • Wind Orb
  • Light Orb
  • Dark Orb
   ×250
• 
  Whorl
  • Infernal Whorl
  • Tidal Whorl
  • Seismic Whorl
  • Tempest Whorl
  • Radiant Whorl
  • Umbral Whorl
   ×250
• Flawed Prism ×250

Creating the 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):

• 
  Trial Fragment
  • Hellfire Fragment
  • Deluge Fragment
  • Wasteland Fragment
  • Typhoon Fragment
   ×20
• Horn of Bahamut ×2
• Meteorite ×10
• Supreme Merit ×20
• Ultima Core ×1

There are only a limited number of Ultima Cores available, and thus only a limited number of Atma/Ultima weapons can be owned at any one time. However, reducing an Atma or Ultima weapon allows you to regain its core and thus choose a different Atma weapon type to build. Cores can be obtained from

• Hosting and clearing an Ultimate Bahamut raid for the first time (1 core per difficulty level)
• Trading in Ultima Unit ×20 in the Shop (3 cores available)
• Trading in a Cloud Commendation obtained from Pride of the Ascendant in the Shop (1 core available)
• Obtaining the free Atma weapon from the side story What Makes the Sky Blue III: 000 and deciding to reduce it.
• Obtaining the free Ultima weapon from the event Heart of the Sun during a rerun and deciding to reduce it. (Not recommended, as this weapon comes fully uncapped and getting another Ultima weapon to that power level will be difficult for early or midgame players.)
• Obtaining the free Ultima weapon from Sierokarte's Knickknack Academy.

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.
