All Ancient Arm Locations and Guardian Battles in Final Fantasy Resonance

There are 12 Ancient Arms to collect in Final Fantasy Resonance, and each can be restored into a powerful Legendary Arm by defeating its guardian inside the Chamber of Arms. Finding some of these requires specific story progression or Enterprise upgrades, so you won’t be able to collect all 12 as soon as the Chamber of Arms becomes accessible.

Here are all 12 Ancient Arm locations in Final Fantasy Resonance, along with their Legendary and Legendary+ stats, effects, guardian weaknesses, and boss strategies.

How to Unlock the Chamber of Arms in Final Fantasy Resonance

The Chamber of Arms becomes accessible during Chapter 5, after obtaining the Enterprise airship at the end of Chapter 4.

Fly northwest of Mobliz Shipyard in Dirnado, the Continent of Wind, to find an ancient ruin floating above the region. Enter the Chamber of Arms and follow the corridor through the portal to reach a large room containing 12 pedestals.

Each pedestal represents an Ancient Arm and provides a clue about where to find it. Once you’ve obtained the Ancinet Arm item, interact with its pedestal to begin a Level 50 guardian battle.

Defeating the guardian consumes the Ancient Arm and replaces it with its Legendary version, which has much better stats and unique passive effects. They’re some of the strongest weapons in the game, rivaled only by Adamantite weapons.

There are three versions of every Ancient Arm:

• Ancient Arm: The original item, usually with just 1 point in its main stats and no special effect.
• Legendary Arm: Obtained after defeating the Level 50 guardian.
• Legendary Arm+: Obtained after the character reaches Level 70 and defeats the Level 75 guardian.

The upgraded versions offer higher stats and additional effects, including a built-in damage cap increase to 99,999 for all eight Legendary weapons.

You only need to restore all 12 Ancient Arms into their regular Legendary versions to unlock the Legendary Arms trophy or achievement. The Level 75 battles are all optional and exist for bragging rights.

All Ancient Arms Stats, Upgrades, and Guardian Strategies

For the guides we’re assuming you have sufficiently leveled your party or have figured out combo setups such as Meltdown spam or Spellblade spam. Check our Visions tier list for the best visions to rank up.

Ancient Greatsword — Ragnarok

Stat	Ancient Greatsword	Ragnarok	Ragnarok+
Physical Attack	1	191	202
Magic Attack	1	99	104
Effect	None	+25% non-elemental damage and Stagger Power	Same effect, plus raises damage cap to 99,999

• Location: Grandshelt Colosseum.
• How to obtain: Win Fledgling League Battle 3.
• Guardian: Alpherg.

The Ancient Greatsword is one of the earliest Ancient Arms you can obtain. Once the Grandshelt Colosseum opens during Chapter 4, enter the Fledgling League and defeat the third opponent.

You’ll receive the Ancient Greatsword as a first-time completion reward. Take it to the Chamber of Arms and interact with the greatsword pedestal to challenge Alpherg.

How to Defeat Alpherg

• Level: 50
• HP: 200,000 in its first form.
• Weaknesses: Ice and Wind initially, Lightning in its later form.
• Absorbs: Water.

Alpherg begins the battle by casting Reflect on itself and your party, making offensive magic useless. Use physical Ice and Wind attacks during the first phase, and avoid Water entirely because Alpherg absorbs it.

Its second form is weak to Lightning, so switch elements once it transforms.

Alpherg also uses Meteor, Hydro Breath, and Strikes of the Duty Bound, which hits random party members eight times. Keep your party healed and focus on staggering each form before it can unleash its stronger attacks.

Defeating Alpherg transforms the Ancient Greatsword into Ragnarok, an excellent weapon for Rain if you’re using a physical attack spamming build.

Ancient Katana — Sasuke’s Blade

Stat	Ancient Katana	Sasuke’s Blade	Sasuke’s Blade+
Physical Attack	1	209	220
Magic Attack	1	160	171
Effect	None	+20% critical-hit rate and physical evasion	Same effect, plus raises damage cap to 99,999

• Location: Crystal Tower, Chapter 8.
• How to obtain: Open the chest west of the Middle Reach save point.
• Guardian: Aldhafera.

You’ll find the Ancient Katana inside the Crystal Tower during Chapter 8. Once you reach the Middle Reach section, look for the save point near the airship entrance. The chest containing the Ancient Katana is just west of this location.

Return to the Chamber of Arms and interact with the katana pedestal to challenge Aldhafera.

How to Defeat Aldhafera

• Level: 50
• HP: 200,000 in its first form.
• Weaknesses: Lightning initially, Wind and Earth in its second form.

Aldhafera becomes more resistant to damage when repeatedly hit between turns, making powerful individual attacks more effective than long multi-hit combinations. It also targets characters with low HP and uses Head Hunting, which can inflict Instant Death. Keep your healer protected and avoid leaving characters with low HP.

During its second phase, switch to Wind and Earth attacks. Aldhafera begins charging powerful attacks, including Meteor, so prioritize Stagger to interrupt them.

Defeating Aldhafera rewards you with Sasuke’s Blade, one of the best weapons for Lasswell thanks to its critical-hit and evasion bonuses.

Ancient Bow — Artemis Bow

Stat	Ancient Bow	Artemis Bow	Artemis Bow+
Physical Attack	1	133	142
Magic Attack	1	174	184
Sanctity	—	155	170
Effect	None	Restores MP equal to 2% of damage taken and +10% healing magic potency	Same effects, plus raises damage cap to 99,999

• Location: Felicitas and Chamber of Arms.
• How to obtain: Complete Chloe’s questline and speak with her at the Chamber of Arms.
• Guardian: Dabih.

The Ancient Bow requires you to progress Chloe’s questline in Felicitas. After completing Secrets Unearthed and unlocking the Enterprise, return to Felicitas in the Kingdom of Grandshelt. Enter the Item Shop in the northern part of town and speak with Chloe.

She’ll eventually appear inside the Chamber of Arms, near the bow pedestal. Speak with her there to receive the Ancient Bow.

How to Defeat Dabih

• Level: 50
• HP: Dabih has 125,000 HP, the Cultist has 70,000 HP, and the Warlock has 65,000 HP.
• Weaknesses: Dabih is weak to Ice and Light, the Cultist to Fire, and the Warlock to Lightning.

Unlike the other guardians, Dabih fights alongside two additional enemies, the Dabih Cultist and Dabih Warlock. During the first phase, you’ll need to deal with their different elemental weaknesses while surviving Dabih’s Gravity attacks. Windstorm is especially dangerous because it removes 99% of the party’s current HP.

In the second phase, all three enemies become weak to Light and begin praying together. If they complete their prayer, they’ll receive powerful stat buffs for four turns.

Use Fina’s Light attacks or Lid’s Mecha Behemoth to trigger a Sweeping Stagger and interrupt the prayer before it finishes. We brute forced the fight with Lasswell and Rain’s Spellblade Mimic combo.

Defeating Dabih and his followers restores Artemis Bow, an excellent weapon for Fina thanks to its healing bonus and MP recovery.

Ancient Hammer — Thor’s Hammer

Stat	Ancient Hammer	Thor’s Hammer	Thor’s Hammer+
Physical Attack	1	151	159
Magic Attack	1	142	150
Sanctity	—	124	136
Effect	None	+30% damage and Stagger Power after landing a physical critical hit	Same effect, plus raises damage cap to 99,999

• Location: Western coast of Dirnado, the Continent of Wind.
• How to obtain: Discover the hidden treasure using the Enterprise’s upgraded radar.
• Guardian: Tegmine.

The Ancient Hammer is hidden on the world map and requires upgrades to the Enterprise’s treasure radar.

First, travel to Gaberada, the Undertown, in Gronoa during Chapter 6. Behind the inn, follow the hidden path down the western stairs to reach an NPC beside the water. Speak to him to obtain the Magi-tenna. You’ll also need the Resonance Stone upgrade to reveal the Ancient Hammer’s magically concealed location.

Once both upgrades are installed, fly to the western coast of Dirnado and look for a cove. Activate the Enterprise’s treasure scanner and follow Lid’s proximity hints until you locate the Ancient Hammer.

Return to the Chamber of Arms and interact with the hammer pedestal to challenge Tegmine.

How to Defeat Tegmine

• Level: 50
• HP: 200,000 in its first form.
• Weakness: Dark initially, Earth in its later forms.
• Absorbs: Water and Light during the first form.

Tegmine has extremely high defenses and takes heavily reduced damage until its Stagger Gauge is broken. It also counters incoming attacks, so repeatedly attacking without preparing is risky.

Start with Dark attacks to build Stagger, then use your strongest abilities once it’s vulnerable.

In the second and third forms, switch to Earth damage. Tegmine also gains access to Ferocious Strike, which can inflict Paralysis, alongside attacks that cause Blind, Silence, Sleep, and Instant Death.

Bring status recovery items and keep your healer protected throughout the encounter.

Defeating Tegmine restores Thor’s Hammer for Lid. Its bonus to damage and Stagger Power after physical critical hits works well with her Mechabo abilities.

Ancient Tome — Last Resort

Stat	Ancient Tome	Last Resort	Last Resort+
Physical Attack	1	112	118
Magic Attack	1	193	204
Sanctity	—	124	136
Effect	None	+10% LB gauge from non-damaging actions; buffs applied last one extra turn	Same effects, plus raises damage cap to 99,999

• Location: Roaming Merchant Ship.
• How to obtain: Purchase for 45,000 Gil.
• Availability: Chapter 7 onward.
• Guardian: Elnath.

The Ancient Tome can be purchased from a roaming Merchant Ship once you reach Chapter 7. These ships appear while you’re flying around the world map. This particular ship is found circling around Grandshelt and Dirnado. When you find it, position the Enterprise above it and interact to access its inventory.

Purchase the Ancient Tome for 45,000 Gil, then return to the Chamber of Arms to challenge Elnath.

How to Defeat Elnath

• Level: 50
• HP: 100,000 in its first form.
• Weakness: Lightning throughout the battle.

Elnath is a mechanical guardian that uses countdown-based attacks and becomes more dangerous as its Stagger Gauge decreases. Lightning attacks are effective against every form and body part.

During the second phase, Elnath summons two arms with different immunities. The Right Arm nullifies magical attacks, while the Left Arm nullifies physical attacks.

The order you destroy them matters because the final arm defeated determines Elnath’s remaining defenses. Defeat the Right Arm last if you’re relying on physical damage, or the Left Arm last if your party specializes in magic.

Its final form uses Wave Cannon and Frenzied Bombardment, so try to stagger it before these attacks activate.

Defeating Elnath transforms the Ancient Tome into Last Resort, one of the best weapons for Nichol. His Formations count as non-damaging actions, allowing him to build his Limit Break gauge while extending the duration of party buffs.

Ancient Firearm — Arcturus

Stat	Ancient Firearm	Arcturus	Arcturus+
Physical Attack	1	237	251
Magic Attack	1	94	100
Effect	None	+10% LB gauge and +1 Luck level on the wielder’s turn	Same effect, plus raises damage cap to 99,999

• Location: Oblivion Palace.
• How to obtain: Collect 76 Tablet Shards.
• Guardian: Alhena.

Collect 76 Tablet Shards from across the world and return to the Enigmatic Princess at Oblivion Palace. This unlocks Chest IV in Treasure Room 3, which contains the Ancient Firearm. Our chapter guides cover all Tablet Shards in each chapter so be sure to check them out.

Take it to the Chamber of Arms and interact with the firearm pedestal to challenge Alhena.

How to Defeat Alhena

• Level: 50
• HP: 240,000 in its first form.
• Weaknesses: Water and Dark in Fire stance, Ice and Dark in Wind stance during the first form.

Alhena switches between Fire and Wind stances, changing its elemental weaknesses throughout the battle.

During its first form, Alhena nullifies magical attacks unless staggered, so focus on physical abilities that exploit its current weakness. In the second form, this immunity reverses, requiring magical attacks instead. If you can spam enough attacks, you can stagger it every turn to ignore the physical immunity.

Water works against Fire stance, while Ice works against Wind stance. Alhena also uses Black Hole, which temporarily removes a character from battle until White Hole releases them. Keep your party’s HP high and avoid relying on a single damage dealer.

Defeating Alhena restores Arcturus for Jake. Its automatic Limit Break generation and Luck bonus work well with his critical-hit abilities.

Ancient Rod — Wizard’s Rod

Stat	Ancient Rod	Wizard’s Rod	Wizard’s Rod+
Physical Attack	1	163	171
Magic Attack	1	216	227
Effect	None	+30% damage when exploiting elemental weaknesses; +20% magical evasion	Same effects, plus raises damage cap to 99,999

• Location: Abandoned Cabin, northeastern Kingdom of Pharm.
• How to obtain: Unlock the cabin using the key obtained in Sian.
• Guardian: Sheratan.

Travel to the northeastern part of the Kingdom of Pharm and attempt to enter the Abandoned Cabin. You’ll discover that the door is locked.

Next, head south to the Town of Sian and speak with the man standing outside the inn in the northwestern part of town. He’ll give you the cabin key, provided you’ve already inspected the locked door.

Return to the Abandoned Cabin, unlock it, and open the treasure chest inside to obtain the Ancient Rod. Take it to the Chamber of Arms and interact with the rod pedestal to challenge Sheratan.

How to Defeat Sheratan

• Level: 50
• HP: 240,000 in its first form.
• Weakness: Fire.
• Immunity: Earth.

Sheratan is a plant-based guardian that uses several status effects, including Poison, Sleep, Paralysis, Charm, and Confusion.

Its most dangerous first-phase attack is Alluring Pollen, which can inflict multiple status ailments across the party. Equip Ribbons if you have them and bring Esuna or other recovery abilities.

During the second phase, Sheratan summons the Fruit of Fury and Fruit of Obsession, which it can consume to strengthen itself.

The Fruit of Fury is weak to Earth, while the Fruit of Obsession is weak to Wind. However, you don’t need to defeat both fruits to win. Focus your Fire attacks on Sheratan, since any remaining fruits disappear when it falls.

Defeating Sheratan restores Wizard’s Rod, an excellent weapon for Sakura thanks to its high Magic Attack and bonus damage when exploiting elemental weaknesses.

Ancient Whip — Fire Birch

Stat	Ancient Whip	Fire Birch	Fire Birch+
Physical Attack	1	151	160
Magic Attack	1	207	217
Effect	None	Damage increases with target debuffs and status ailments; extends inflicted effects by one turn	Same effects, plus raises damage cap to 99,999

• Location: Oblivion Palace.
• How to obtain: Collect 84 Tablet Shards.
• Guardian: Nunki.

The Ancient Whip is another reward from the Enigmatic Princess at Oblivion Palace. You’ll need to collect 84 Tablet Shards to unlock Chest VI in Treasure Room 3. Open it to obtain the Ancient Whip. Our chapter guides cover all Tablet Shards in each chapter so be sure to check them out.

Bring it to the Chamber of Arms and interact with the whip pedestal to challenge Nunki.

How to Defeat Nunki

• Level: 50
• HP: 300,000 in its first form.
• Weaknesses: Fire, Water, Wind, and Ice in sequence during the first form, then Earth in its second form.

Nunki is one of the more complicated guardian fights because its elemental weaknesses change repeatedly throughout the battle. During its first form, the weakness progresses through Fire, Water, Wind, and Ice before reaching a final stage without an elemental weakness.

Several stages also absorb the element used against the previous one, so you’ll need to switch attacks instead of repeatedly using the same spell.

Its second form is weak to Earth but gains powerful physical attacks, including Unbound Fangs, which can remove 90% of a character’s maximum HP. The final stage can also act three times per turn and inflict Paralysis, so keep your healer protected and bring status resistance.

Defeating Nunki restores Fire Birch for Archwitch Fina. Its damage bonus scales with the debuffs and status ailments affecting enemies, making it an excellent match for her abilities.

Ancient Cuirass — Tatenashi Armor

Stat	Ancient Cuirass	Tatenashi Armor	Tatenashi Armor+
Physical Defense	1	259	272
Magic Defense	1	153	165
Speed	—	-30	-35
Effect	None	Prevents Instant Death	Prevents Instant Death and increases damage dealt by 20%

• Location: Grandshelt Colosseum.
• How to obtain: Win Brawler League Battle 5.
• Guardian: Sadalsuud.

Return to the Grandshelt Colosseum and progress through the Brawler League until you reach its fifth battle. Defeating the opponent rewards you with the Ancient Cuirass as a first-time completion reward.

Take it to the Chamber of Arms and interact with the cuirass pedestal to challenge Sadalsuud.

How to Defeat Sadalsuud

• Level: 50
• HP: 130,000 in its first form.
• Weaknesses: Changes between Ice, Fire, Wind, and Water.

Sadalsuud constantly changes elemental weaknesses through Barrier Shift. During its first form, only one element is effective at a time, while the remaining elements are nullified. Use Libra after each transformation to identify its current weakness.

In the second phase, Sadalsuud summons four elemental wings, each with its own weakness. Destroying a wing strengthens Sadalsuud, granting additional actions, defense, or offensive power. Because the wings disappear when Sadalsuud is defeated, you can focus your attacks on the boss instead of clearing every wing individually.

Watch for Windstorm, which removes 99% of the party’s current HP, and heal immediately afterward.

Defeating Sadalsuud restores Tatenashi Armor, which offers excellent physical defense and protection against Instant Death. Its only drawback is the Speed penalty.

Ancient Garment — Mirage Vest

Stat	Ancient Garment	Mirage Vest	Mirage Vest+
Physical Defense	1	229	241
Magic Defense	1	153	171
Effect	None	Nullifies damage once per battle	Nullifies damage and status ailments once per battle

• Location: Eastern coast of Gronoa, the Shuttered Land.
• How to obtain: Discover the hidden treasure using the Enterprise radar.
• Guardian: Vindemiatrix.

Like the Ancient Hammer, the Ancient Garment is hidden on the world map and requires the Enterprise’s treasure radar. You can obtain the Magi-tenna upgrade during Chapter 6 by speaking to the NPC behind the inn in Gaberada, the Undertown. Follow the hidden western staircase to reach him.

After installing the upgrade, fly and scan the east of the platform where you land and enter Granoa. Use the treasure scanner and follow Lid’s proximity hints to uncover the Ancient Garment.

Return to the Chamber of Arms and interact with the garment pedestal to challenge Vindemiatrix.

How to Defeat Vindemiatrix

• Level: 50
• HP: 250,000 in its first form.
• Weakness: Dark.
• Immunity: Light.

Vindemiatrix specializes in magic and goes through several consecutive forms. Its opening form can act five times per turn, making it extremely dangerous if your party isn’t prepared. It uses elemental magic, Charm, Confusion, and Meteor, so bring status resistance and magical defense buffs.

During the second phase, Vindemiatrix begins draining MP whenever you attack it. After enough MP-draining counters, it prepares Chain Holy, a powerful Light attack that bypasses Reflect.

Dark attacks are effective throughout the fight, or you can just brute force the fight with Staggers.

Defeating Vindemiatrix transforms the Ancient Garment into Mirage Vest, a defensive item that completely nullifies one instance of damage per battle.

Ancient Cloak — Lordly Robes

Stat	Ancient Cloak	Lordly Robes	Lordly Robes+
Physical Defense	1	159	166
Magic Defense	1	217	238
Effect	None	Allows magic to bypass Reflect	Allows magic to bypass Reflect; increases maximum MP by 30%

• Location: Roaming Merchant Ship.
• How to obtain: Purchase for 40,000 Gil.
• Guardian: Shaula.

The Ancient Cloak is sold by a roaming Merchant Ship after you reach the Town of Duggle at Gronoa continent. This one can be found circling the region between Mysidia and Pharm. Find it and position the Enterprise above it, and interact to open its shop.

Purchase the Ancient Cloak for 40,000 Gil, then take it to the Chamber of Arms and interact with the cloak pedestal to challenge Shaula.

How to Defeat Shaula

• Level: 50
• HP: 240,000 in its first form.
• Weakness: Wind.
• Immunity: Earth.

Shaula switches between physical and magical modes, changing how you should attack it.

During the second phase, its physical mode nullifies physical attacks, while its magical mode nullifies magic. Bring both physical and magical Wind abilities so you can continue damaging it regardless of the current mode.

It also uses status effects, including Paralysis, Silence, Poison, Petrification, and Charm.

Its stronger attacks include Ferocious Strike and Calamity, which can hit the entire party multiple times. Keep your HP high and use Wind attacks to stagger Shaula before it unleashes them.

Defeating Shaula restores Lordly Robes, which are useful against enemies that rely on Reflect to protect themselves from magic. Lordly Robes+ also increases the wearer’s maximum MP by 30%.

Ancient Accessory — Gold Hairpin

Stat	Ancient Accessory	Gold Hairpin	Gold Hairpin+
Magic Attack	1	30	60
Effect	None	Halves MP consumption	Halves MP consumption and increases Speed by 20%

• Location: Quarry Cave, western Zoldaad Empire Territory.
• How to obtain: Open a chest inside the cave.
• Guardian: Brachium.

The Ancient Accessory is found inside Quarry Cave, located on a small island off the western coast of Zoldaad.

You’ll need the Enterprise to reach this island, so it becomes accessible after unlocking the airship at the end of Chapter 4. Land near the cave, head inside, and open the treasure chest to obtain the Ancient Accessory.

Return to the Chamber of Arms and interact with the accessory pedestal to challenge Brachium.

How to Defeat Brachium

• Level: 50
• HP: 200,000 in its first form.
• Weakness: Light.
• Immunity: Dark.

Brachium alternates between physical and magical forms during its opening phase, switching whenever you trigger its counters.

It uses Gravity attacks, status ailments, and Instant Death abilities. Its Execution and Cleave Clean attacks ignore Instant Death resistance, so accessories like Safety Bit won’t protect you. Instead, spam Reraise and focus on staggering Brachium to interrupt Execution before it activates.

In its second form, Brachium gains stronger buffs and can remove your party’s buffs with Dispelga.

Its most dangerous attack, Judgment of the Demon, removes 99% of the party’s current HP and strips buffs. Keep your party healed and use powerful Light attacks such as Fina’s Luminant Cannon to maintain pressure.

Defeating Brachium transforms the Ancient Accessory into Gold Hairpin, one of the most useful accessories for MP-usage-heavy characters.

That covers all 12 Ancient Armaments and their respective Guardian boss fights. For more guides, check out our Visions Tier list and the best mods for Final Fantasy Resonance.
