The Twelve Legendary Arms are among the most powerful weapons and armor in Final Fantasy Resonance. Square Enix detailed them on July 16, 2026 as one of the game's named high-difficulty tracks.
How to Claim Them
Twelve pieces of equipment lie sealed at points scattered across the world. Each one can only be claimed after breaking its seal and defeating the ruthless monstrosity sealed within it. Japanese material describes the reward as the strongest weapons and armor in the game, and frames the whole track as preparation for taking on even greater foes.
The Chamber of Arms
If you are unsure where one of these weapons is located, you can visit the Chamber of Arms, a room somewhere in the world where hints for each of the twelve can be viewed. It functions as the hunt's index rather than as a fast route to the rewards.
Detail | Value |
|---|---|
Count | Twelve pieces of equipment |
Location | Sealed at points scattered across the world |
Requirement | Break the seal, then defeat the monstrosity sealed within |
Reward | Some of the strongest weapons and armor in the game |
Hints | Viewable in the Chamber of Arms |
The September 2026 Restatement
Square Enix returned to the track on September 10, 2026 with a dedicated entry in its Japanese video series on the game's completionist content, and named the entry for the Chamber of Arms itself. The description matches the July account and sharpens one point: twelve arms lie scattered across the world behind seals, a boss sleeps inside each seal, and defeating that boss is what releases the arm. The reward is again given as the strongest weapons and armor in the game. The Japanese Steam store description, rewritten ahead of the free demo, names the Chamber of Arms directly as well.
Detail | July 2026 | September 10, 2026 |
|---|---|---|
What is sealed | Twelve pieces of equipment | Twelve arms, scattered worldwide |
The obstacle | A ruthless monstrosity sealed within | A boss sleeping inside each seal |
The reward | Some of the strongest weapons and armor in the game | The strongest weapons and armor in the game |
The Chamber of Arms | A room holding hints for each of the twelve | Named as the subject of the video and in the Steam store description |
Related Optional Content
Other optional tracks were named later and sit alongside this one: Mighty Foes presiding over the caverns that dot the land, Secret Dungeons set apart from the main story, and the endgame fights against Gilgamesh and Ultima Weapon. The Colosseum is the other high-difficulty track Square Enix detailed on the same day. Square Enix added one more optional opponent on September 3, 2026: Sephiroth, whom players can find and challenge for a special reward. He has not been placed inside any of the tracks above, so he is recorded at Side Content and Endgame.
This track is separate from Aileen's adamantite forging, which is its own weapon source.
Ancient equipment and guardian trials
An Ancient equipment piece is the base for its corresponding Legendary Arm. Take the base to its pedestal in the Chamber of Arms and start the level 50 trial. Defeating the guardian transforms that base into the Legendary Arm listed below.
Ancient equipment | Legendary Arm | Guardian |
|---|---|---|
Ancient Greatsword | Ragnarok | Alpherg |
Ancient Katana | Sasuke's Blade | Aldhafera |
Ancient Bow | Artemis Bow | Dabih |
Ancient Hammer | Thor's Hammer | Tegmine |
Ancient Tome | Last Resort | Elnath |
Ancient Firearm | Arcturus | Alhena |
Ancient Rod | Wizard's Rod | Sheratan |
Ancient Whip | Fire Birch | Nunki |
Ancient Cuirass | Tatenashi Armor | Sadalsuud |
Ancient Garment | Mirage Vest | Vindemiatrix |
Ancient Cloak | Lordly Robes | Shaula |
Ancient Accessory | Gold Hairpin | Brachium |
After clearing the level 50 trial, its level 75 trial becomes available once the required character reaches level 70 or higher. Defeat the guardian again to upgrade the Legendary Arm to its + version.
Tablet Shard Rewards includes the Ancient Firearm at 76 shards and the Ancient Whip at 84 shards.
Guardian battle preparation
Guardian | Response |
|---|---|
Shaula | Modes nullify one damage type. Read the current mode and use the effective type; repeated attacks shorten the time to its next change. |
Brachium | Use magic against its physical mode and physical attacks against its magical mode. Light helps build stagger. |
Vindemiatrix | Draw its frequent opening attacks with a tank and use Dark. Losing body parts reduces its attack frequency. |
Aldhafera | Prepare against Confuse and Berserk. Use Lightning in phase one, then Wind or Earth in phase two; avoid unnecessary attacks that reduce later damage. |
Tegmine | Prepare against Instant Death, Blind, Sleep and Silence. It counters attacks and has high defenses; Deprotect and Deshell can help. |
Alhena | Phase one nullifies magic and phase two nullifies physical damage. Check its Fire/Wind weakness changes and avoid unnecessary attacks. |
Elnath | Use Lightning while watching the countdown. Excessive stagger-gauge reduction between its actions can give it an Additional Attack. |
Sheratan | Use Fire and prepare ailment protection. Destroy the fruits in phase two before it consumes them for permanent buffs. |
Sadalsuud | Prepare against Paralysis, Petrification and Instant Death. Check each Barrier Shift and reduce incoming magic damage. |
Alpherg | Use physical attacks while Reflect is active. In phase two, use Lightning once Reflect has expired. |
Nunki | Recheck weaknesses and resistances as they change. Prepare protection against Paralysis. |
Dabih | Bring both damage types: Dabih resists physical attacks while its Cultist and Warlock resist magic. Prepare Light, Ice, Fire and Lightning coverage. |
