Chamber of Arms in Final Fantasy Resonance: All 12 Ultimate Weapons and Trials

Quick answer: The Chamber of Arms has 12 altars, one for each Ancient piece. Bring an Ancient piece to its altar and beat a Lv. 50 trial boss to restore it (for example, the Ancient Greatsword becomes Ragnarok). Then, once the named character reaches Lv. 70, an ultimate trial against a Lv. 75 version of the same boss turns it into a “+” version: the eight “+” weapons add “Raises damage cap to 99999.”, while the armor and accessory “+” versions get stronger effects. Trials cost no gil or materials; each one uses up the item you bring and gives the new one. You reach the Chamber of Arms later in the story.

Ancient pieces come from Colosseum battles, chests, the Merchant Ship, the Tablet Shard collector and Chloe’s side event. The table below lists every piece with its source, both trials and the gear you end up with. For exact locations, check where to get all 12 Ancient pieces.

How the Chamber of Arms trials work

The game’s Steam page describes “the Chamber of Arms with formidable foes sealed within legendary weapons”, and that is how it plays out. Each Ancient piece goes through two trials. The Ancient Greatsword is used as the example below, but every altar uses the same pattern. If you still need that piece, here is how to get the Ancient Greatsword.

Check the altar to see what it wants. If you don’t have the Ancient piece, the altar only gives a hint, such as “Acquire the ancient greatsword whose gleam has long since faded.”

Return with the Ancient piece and talk to the altar again. It now says “Should you desire its power, take up the trial of the greatsword.” and asks “Will you take up the trial?” The first trial has no level requirement, so you can accept right away.

Beat the Lv. 50 trial boss. When you win, the Ancient piece is used up, and the game says the Ancient piece “has regained its strength, transforming it into” the restored item, which for the greatsword is Ragnarok.

Bring the restored item back to the same altar. If the named character is under the level requirement, the altar says, for example, “O bearer of Ragnarok, its true strength shall be granted only unto those deemed worthy.” and “You must hone your abilities if you are to undergo the trial.” You can’t take the second trial until you meet that requirement.

Get the named character to Lv. 70 or higher, then return to the altar. It now says “Should you desire its true strength, you must take up the ultimate trial of the greatsword.” Accept it to fight the Lv. 75 version of the boss.

Win the ultimate trial. The game says “The true power of” the item “has been awakened, transforming it into” the “+” item, followed by a line like “Well done. You have drawn out the true strength of Ragnarok.” The restored item is used up and you receive its “+” version.

Lv. 70 is not the level cap: characters go up to Lv. 99, as the max level page shows. Rain is the named character for the greatsword and for all four armor and accessory trials, so leveling Rain opens five ultimate trials.

Weapons

Eight Ancient pieces become weapons, one for each weapon type. Each “+” version keeps the effect below, gains a little attack, and adds “Raises damage cap to 99999.” For every other weapon in the game, see the full weapons list.

Armor and accessory

The other four Ancient pieces become armor and an accessory. Rain is the named character for all four ultimate trials. Their “+” versions don’t raise the damage cap. Instead, each gets a new or stronger effect, listed in the paragraph below the table.

Restored item	Phys. Def / Mag. Def	Effect	+ version Phys. Def / Mag. Def
Tatenashi Armor (Heavy armor)	259 / 153 (Speed -30)	“Prevents Instant Death.”	272 / 165 (Speed -35)
Mirage Vest (Light armor)	229 / 153	“Nullifies damage received once per battle.”	241 / 171
Lordly Robes (Robe)	159 / 217	“Enables magic to hit targets under the effect of Reflect.”	166 / 238
Gold Hairpin (Accessory)	Mag. Atk 30	“Halves MP cost.”	Mag. Atk 60

Tatenashi Armor+ adds “Increases damage dealt by 20%.” Lordly Robes+ adds “Increases max MP by 30%.” Gold Hairpin+ adds “Increases speed by 20%.” Mirage Vest+ changes its effect to “Nullifies damage and status ailments once per battle.”

Trial bosses

Each altar’s ultimate trial uses the same boss as its first trial, now at Lv. 75 with several times the HP. The Ancient Bow is the only one that is a three-enemy fight: Dabih, Dabih Cultist and Dabih Warlock, in both trials. The other story and optional fights are on the bosses list.

Aileen’s Adamantite weapons

Aileen’s weapons are not part of the Chamber of Arms, and she doesn’t require an Ancient piece. During her Chapter 6 event, Aileen, the rebels’ weaponsmith, uses 1 Adamantite to forge a weapon for the character you select. Her eight options are:

Rain: Save the Vermillion (Greatsword, 179 / 93), “Reduces damage taken from physical and magic attacks by 20%.”
Lasswell: Shisui (Katana, 197 / 148), “Grants Hone Senses and Placidity for 5 turns at the start of battle.”
Fina: Elysium (Bow, 114 / 162), “Increases potency of healing magic by 20%.”
Lid: Mechabo Hammer SUPER (Hammer, 142 / 133), “Grants Overclock and allows the wielder to act first at the start of battle.”
Nichol: Codex Providentiae (Tome, 106 / 181), “Grants Tactic: Fluid Warfare for 3 turns and allows the wielder to act first at the start of battle.”
Archwitch Fina: Abyss (Whip, 130 / 178), “Increases the duration of debuffs and status ailments inflicted by the wielder by 2 turns.”
Jake: Caelum Renatum (Firearm, 222 / 88), “Raises luck level by 8 at the start of battle. Restores 2% of max MP upon dealing damage with a standard attack.”
Sakura: Roselia (Rod, 154 / 204), “Grants Concentrate for 3 turns and Sage’s Eye for 4 turns at the start of battle.”
