This event is connected to multiple event storylines and Fate Episodes. See Event Teaser Page for more details.

In the beginning, god created the world and man.
The land took shape, and fed man its abundance.
Yet this realm of peace filled not man's heart.
Thisting for greater prosperity, man defied god.
To man's aid came the whispers of a great bird.
So did man conquer god, and was god torn atwain.
Thus, the world assumed its present form.

But within this realm devoid of divinity,
a foreboding light now flickers to life,
showing signs of flaring into an untamed blaze.
O, beings that resist thy fate.
O, tome of wisdom that binds the enigmas.
Gather thy whishes and wills into one place,
and of them an immortal, invincible force make.

Choosing Your Free Ultima Weapon

For Beginners

Ultima Weapons are a unique weapon series that can equip different keys to gain different effects. In this event, players will receive a free 5★ uncapped Ultima weapon which is usually reserved for rank 200+ players who can clear Super Ultimate Bahamut! As a new player, it's important to choose your free weapon and its keys wisely. Below is a recommended weapon setup that will most widely benefit all of your teams.

Recommended Weapon Type	Recommended Element	Recommended Keys
Ultima Staff	03 05	1st Slot Gauph Key of Strength Big boost to allies' ATK based on how high HP is (Only affects this weapon type specialty allies. ATK boost is based on weapon skill level) Gauph Key of Strength	2nd Slot Gauph Key α 10% Boost to one-foe attack DMG cap Gauph Key α (Auto Cap)	3rd Slot Gauph Key Tria Amplify all allies' superior elemental DMG by 25% Gauph Key Tria (Lvl 200 required)
Ultima Sword	03 04 06

What Weapon Type Affects

Your Ultima weapon type only affects the boost it gives on its first key slot as well as its ability to be used as a mainhand weapon. This boost can largely be ignored in early game setups. Further in game progression, players will craft different Ultima Weapon types to min-max their damage output for key characters.

Why Gauph Keys Are Important

It's really important to level up your Ultima Weapon to lvl 200 because it will gain access to its 3rd Gauph Key slot which is the most impactful part of this weapon. Once this key slot is unlocked, be sure to equip the Gauph Key Tria. This gives the weapon a very strong Seraphic-type ATK boost, even higher than a fully upgraded Seraphic Weapons which means you can replace them with your new Ultima Weapon in all of your grids when fighting at elemental advantage.

As previously mentioned, the 1st key slot only boosts allies that match the weapon type of the Ultima Weapon being used. It's nice when the weapon proficiencies match up, but it shouldn't be forced. This key is affected by weapon skill, but for new players it's less important to raise than other weapons like Bahamut Weapons or even Dark Opus Weapons.

The 2nd key slot gives a damage cap up weapon skill based on the key selected. We suggest equipping the Gauph Key β which increases the cap of Skill DMG, as this type of damage is the easiest to cap even for beginner players.

Alternative Weapon Choices

Main article: Advanced Grids#5★ Ultima Weapons

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.
