Baldesion Arsenal Overview

The Baldesion Arsenal is the only raid available within The Forbidden Land, Eureka, introduced in Stormblood. The raid features multiple bosses and small-scale encounters, requiring a large group of players with good coordination to complete. The raid is designed for up to 56 players but can be entered with undersized parties should they still meet the entry requirements.

Entry to The Baldesion Arsenal is located within The Forbidden Land: Eureka Hydatos and will require completing several prerequisites before players can enter the raid.

Raid Guide

Eureka Overview

Eureka allows players to progress their character's power in many different ways, each serving to help the player in all Eureka-related Field Operations.

These upgrades are not strictly required to clear the raid but are generally recommended if you have lots of Gil and/or plan to spend a lot of time in Eureka-related Field Operations.

Logos Actions and Wisdoms

Logos Actions, first introduced in The Forbidden Land: Eureka Pyros, allow the use of up to 2 specialised actions at any time that have various, powerful effects.

To obtain and equip them, players must first acquire the necessary Logograms. These can be dropped by mobs and Notorious Monster FATEs, found in coffers and also purchased off the Marketboard. Afterwards, you can speak with Drake to appraise them, and finally combine them at the Logos Manipulator to create the actions.

Wisdoms, also introduced in The Forbidden Land: Eureka Pyros are a subset of Logos Actions that passively boost certain stats, lasting until the player leaves the instance or changes jobs.

To see a complete table of Logos Actions, along with their effects, recipes and Logogram acquisitions, please see the website below.

Logos Actions List

Aethertight Flasks

Aethertight Flasks, introduced in The Forbidden Land: Eureka Hydatos are items used to increase the amount of Logos Action slots available to the player.

Aethertight Flasks are only obtainable via Silver Happy Bunny Lockboxes in Hydatos, and each flask can be traded with the Expedition Alchemist up to 3 times for a maximum of 6 total Logos Action slots.

6th and 7th Magicites

Certain Notorious Monsters within both The Forbidden Land: Eureka Pyros and The Forbidden Land: Eureka Hydatos have a very rare chance to drop a unique material.

You must obtain 1 of each unique material available within each Field Operation and speak with the Expedition Engineer located within each Field Operation to earn your 6th and 7th magicites. You may also purchase these materials off the Marketboard.

Below is a table listing the name of the unique material and the Notorious Monster FATE it drops from.

Pyros	Hydatos
Lamebrix's Dice (Thirty Whacks)	Molech's Horn (Bullheaded Berserker)
Ying Yang's Tissue (Haunter of the Dark)	Goldemar's Horn (Duty-free)
Skoll's Claw (Heavens' Warg)	Ceto's Claw (Stone-cold Killer)

Cassie Earring, Blitzring and Optical Hat

Certain Notorious Monsters within The Forbidden Land: Eureka Pagos have a very rare chance to drop a piece of gear that increases the player's Haste stat while in Eureka-related Field Operations, with each point reducing the GCD's cooldown by an additive 1%.

Both the Cassie Earring and Blitzring are available as rare drops, whereas the Optical hat can be obtained by collecting an assortment of items across the Field Operation and crafting them into a singular item, then completing the requisite FATE. All these items are also purchasable on the marketboard.

These items are extremely rare, expensive and optional for only a minor increase in damage (if your job directly benefits with more skill/spell speed). In the Optical Hat's case, it is outclassed by Elemental +2 headgear or Vermilion chestpieces due to the Elemental Bonus attached to both pieces, offering more raw offence and defence.

Elemental +2 Sets and Physeos Weapons

Elemental +2 Sets and Physeos Weapons are obtainable gear that offers substantial increases in universal offence and defence by increasing your Elemental Bonus stat while in Eureka-related Field Operations.

The Elemental sets are first available from The Forbidden Land: Eureka Pyros, and require players to fulfill 2 conditions to unlock the Expedition Artisan:

1. Obtain an Elemental stage weapon.
2. Discover 50 Logos Actions.

The sets can then be augmented with the Expedition Artisan within The Forbidden Land: Eureka Hydatos, first to +1 with Hydatos Crystals and finally to +2 with Eureka Fragments, dropped from The Baldesion Arsenal.

To upgrade your weapon to a Physeos Weapon, you must exchange both your Eureka stage weapon and 100 Eureka Fragments with Gerolt within The Forbidden Land: Eureka Hydatos.

Kirin's and Vermilion Chestpieces

Kirin's and Vermilion chestpieces also offer a substantial increase in Elemental Bonus and Haste.

Kirin's and Vermilion chestpieces are available for exchange with the Nostalgic Fellow in Kugane using Cryptic Seals and Damascene Cloth, both obtainable within The Baldesion Arsenal. You may also buy the armour, seals and cloths off the Marketboard or ask your local Field Operation groups for any handouts as they aren't used for much else.

Raid: The Baldesion Arsenal

WARNING

This guide will entail Set Ups and strategies for an ANYPROG run, meaning that any player at any prog-point in the raid can join.

Depending on what type of run it is and who is running it, your assigned roles and Logos Actions in the raid can change considerably. Please confirm your role and actions with the raid leader's linked resources, and be sure to ask questions if you are unsure of anything.

Visual Guide

This visual guide details entry requirements, party and Logos Action setup, boss abilities and their potential callouts. The guide also features the trash mobs between each boss, trap zones and loot. While this guide isn't 100% accurate on boss timelines, it should give any player a general idea of the mechanics in any given fight.

Entry Requirments

Any player who is Elemental Level 60, has completed all available story objectives in The Forbidden Land: Eureka Hydatos and has spoken with the Expedition Scholar can enter The Baldesion Arsenal.

To enter The Baldesion Arsenal, a minimum of 8 players must have met the above prerequisites to spawn the Umbral Turbulence weather and the following Notorious Monster FATE: I Don't Want to Believe.

I Don't Want to Believe

Dispel L is required to remove any personal buffs the Notorious Monster gives itself. Look for the cast "Fluorescence".

Players can receive the Aetherially Primed buff for 10 minutes from this FATE provided they fulfil the following conditions:

• They are Elemental Level 60 before the FATE concludes.
• They are within the FATE's boundaries when it concludes.
• They achieve a Gold Rating.

This buff allows players to access 1 of the 48 Aetheric Nodes scattered around Hydatos that spawn shortly after the FATE concludes. There are 2 kinds of Nodes that appear:

1. Unstable Aetheric Nodes, spawning 3 minutes after the FATE concludes and blue in colour. Requires the buff and the use of an Aetheric Stabilizer to access.
2. Stable Aetheric Nodes, spawning 6 minutes after the FATE concludes and red in colour. These can be accessed by anyone with the buff.

Set Up

NOTE

The nature of Logos Actions allows players to take on other roles to cover any missing bases of tanking, healing and damage.

Logos Actions List

Each party should aim for:

• x1 Tank
• x2 Healers
• x5 DPS

Extra tanks and healers are welcome should the whole raid not have enough players to clear comfortably healthy or need a safety net for Proto Ozma.

Additionally, everyone should have a Spirit of the Remembered buff active AT ALL TIMES, available from the Logos Action of the same name. It offers you a 70% chance to be automatically revived if you die, a very useful tool to circumnavigate the restriction on standard raises. If it gets consumed, find a safe moment to refresh your buff, even during battle.

Depending on your role, it's useful to have certain Wisdoms active to further amplify your role in the raid, these are:

Role	Wisdom
Tank	Main Tank - Indomitable or Guardian Off Tank - Martialist
Healer	Pure Healer - Ordained or Aetherweaver Barrier Healer - Templar or Aetherweaver
Melee DPS	Duelist or Skirmisher
Phys. Ranged DPS	Fiendhunter or Skirmisher
Caster DPS	Elder or Skirmisher

Finally, at least a couple of DPS players should have the Logos Action Perception L to uncover any traps littered throughout the raid as well as the portal leading to the secret rooms.

Below are mini-guides and example loadouts for each role within The Baldesion Arsenal:

Tank LoadoutHealer LoadoutDPS LoadoutPerception L Guide

Encounters

Notable Trash Mobs

While trash mobs generally aren't very threatening, there are a few sprinkled throughout The Baldesion Arsenal with dangerous casts that we generally want to avoid or interrupt.

In general, you shouldn't pull any mobs unless you are a tank, have defensive Wisdoms and have rotated your Magia board defensively.

Below is a table noting some mobs and their dangerous casts, as well as a link to a more in-depth guide on the trash mobs.

Enemy	Attack
Arsenal Poroggo	Toy Hammer - Chunks your health by 90% of your max HP.
Arsenal Byblos	Page Tear and Tail Cleave - An untelegraphed front and back conal AoE respectively.
Arsenal Calcabrina	Terrifying Glance - An untelegraphed front conal AoE that inflicts Confused.
Arsenal Centaur	Berserk - Large damage buff to self. Dispel or interrupt the cast with Sleep.
Arsenal Sprite	Banish III - Small but heavy-hitting AoE that also removes a random buff from all players hit. Stun or Interrupt.
Arsenal Strix	On the Properties of Darkness - Removes a random buff from any player affected. Stun or interrupt the cast with Sleep.

Boss Timelines and Trash Mobs

Boss 1 - Art and Owain

Art and Owain are located in separate rooms and have no strict enrage, but they must both be engaged in combat at the same time and reach 1 HP to be defeated.

Art can be found through the West hallway and Owain can be found through the East hallway.

Art

Art is Earth-aspected, so adjust your Magia Board to Earth for defence or Water for offence.

Art will begin the fight with the following sequence:

1. Thricecull - A tankbuster.

2. Two unique casts of Legendcarver and Legendspinner - A PB-AoE and Donut respectively.

3. Acallum no Senorach - A raid-wide.

4. Mythcall - Summons 4 spears around the arena that mimic the Legendcarver or Legendspinner the boss uses.

   Players should first dodge the original cast, then dodge that same attack from the spears.

5. Legendcarver or Legendspinner

6. Acallum no Senorach

7. Thricecull

8. Mythcall

9. Legendcarver or Legendspinner

From here, Art will enter a loop of attacks until it'd defeated, adding in 3 new attacks to the fray:

• Legendary Geas - Targets a player with an avoidable AoE and turns the floor black in colour.

Players moving while the floor is darkened will be inflicted with a Bleed and Heavy. This is followed by multiple line AoEs that become difficult to dodge if you have Heavy.

• Pitfall and Glory Unearthed - The boss will jump away, creating a proximity AoE and targeting a random player with a large, chasing AoE.

• The targeted player must bait the AoEs away from both the party and the proximity AoE.
• Art will return at the centre of the proximity AoE.

• Piercing Dark - A targeted AoE on 2 players.

Owain

Owain is both Fire and Ice-aspected, so adjust your Magia board to Fire and Ice respectively for defence or Wind and Fire respectively for offence.

Owain will begin the fight with the following sequence:

1. Thricecull - A tankbuster.

2. Acallum no Senorach - A raid-wide.

3. Mythcall - Summons 8 spears around the arena that become Fire or Ice-aspected in the following cast.

4. Elemental Shift - Owain shifts its own element and the spears around itself to either Fire or Ice.

5. Elemental Magicks - A telegraphed PB-AoE that also casts from any spears that are the same element as the boss.

   Players should position at a spear of the opposite element to Owain.

6. Thricecull

7. Acallum no Senorach

8. Elemental Shift

9. Elemental Magicks

10. Thricecull

11. Spiritcull - 2 players are marked with a targeted AoE and several other players are marked with red triangles.

    Any player with a red triangle mark should pair up with another marked player.

12. Thricecull

From here, Owain will enter a loop of attacks until it's defeated, adding in 2 new attacks to the fray:

• Pitfall and Piercing Light - The boss will jump away, creating a proximity AoE where it lands and targeting 2 players with a targeted AoE.

• Owain will return at the centre of the proximity AoE.

• Hands - 2 Ivory Palms will spawn around the arena, tethering to a player. These adds will swiftly move towards the tethered player but freeze in place if being looked at by them. They also have a damage resistance buff that can be removed by being in close proximity of its tethered player.

  Tethered players should look at their hand and move towards it to remove its buff, making sure not to touch it directly.

  Everyone else can wait until the buff is removed before DPS'ing them down.

Boss 2 - Raiden

Raiden also has no strict enrage but still has attacks that can instantly kill any players not paying attention.

Raiden is Lightning-aspected, so adjust your Magia board to Lightning for defence and Earth for offence.

Raiden will begin the fight with the following sequence:

1. Spirits of the Fallen - A raid-wide.

2. Shingan - A tankbuster.

3. Thundercall - Creates a bleed wall along the outer edge of the arena.

4. Ame-no-Sakahoko, a massive untelegraphed PB-AoE centred on itself as well as a large backflip, landing a considerable distance behind where the boss is facing.

5. Whirling Zantetsuken, a massive untelegraphed donut with the only safe spot being directly under its hitbox.

Raiden will then cycle through the following attacks until its HP falls below 70% or it has completed the cycle once:

1. Spirits of the Fallen
2. Ame-no-Sakahoko
3. Whirling Zantetsuken

TANK

If you're the current MT, position Raiden at the wall at the beginning of the fight so that the boss has ample space to backflip.

Upon either the threshold being passed or the cycle completing, Raiden will disappear and reappear at the East or West of the arena, becoming untargetable and beginning the following sequence:

1. Lateral Zantetsuken and Ball Lightning - A half-room cleave dictated by the direction its sword is pointing towards. In addition, Ball Lightning adds will spawn under players and begin casting Shock, a telegraphed PB-AoE.

   All players should stack up in the middle after Raiden disappears and look for the boss on either side of the arena to watch the sword. When the AoEs appear, players can start running away from the direction the sword is pointing towards.

2. Spirits of the Fallen

3. Lancing Bolt - 6 massive targeted AoEs on random players, spawning Streak Lightnings where each player was hit.

   Streak Lightnings are Lightning aspected adds and render Raiden invulnerable while it casts its next attack.

4. Ultimate Zantetsuken, an enrage that wipes the party if the cast finishes.

   All players must DPS down the Streak Lightnings before Raiden can finish casting Ultimate Zantetsuken.

5. Spirits of the Fallen

6. Booming Lament - A large telegraphed AoE targeted on a player.

From here, Raiden will enter a loop of attacks until it's defeated, adding in 4 new attacks to the fray:

• Cloud to Ground - Multiple exaflares spawn along a side of the arena.

  Players can position in later-spawning lanes of exaflares, and then move into earlier-spawning lanes as the AoEs travel along the arena.

• Bitter Barbs - Several players are tethered together and several other players are targeted with a small telegraphed AoE.

  Tethered players must run away from each other to break the tether, keeping in mind that some exaflares are still travelling across the arena.

• For Honor - An untelegraphed PB-AoE.

• Levinwhorl - A heavy-hitting raid-wide.

Secret Rooms and Expedition Support

To remove the buff that Absolute Virtue has, players inside the raid are required to spawn the Notorious Monster FATE: The Baldesion Arsenal: Expedition Support and players outside the raid are required to complete it.

To spawn it, players must first discover the secret rooms via a portal in one of the rooms before Absolute Virtue. The portal can be uncovered via the use of Perception L.

There are 6 secret rooms, each aspected to an element and each with a button that when all simultaneously pressed, will do the following:

• Spawn the Notorious Monster FATE The Baldesion Arsenal: Expedition Support.
• Lock the entrance to the room and spawn enemies that must be killed to unlock the entrance.

NOTE

Because the nature of the buff on Absolute Virtue only requires that the FATE be spawned and completed, you may opt to cheese a room instead. There are 2 available methods to cheese a room:

1. Use Return to exit the room AND the raid as a whole.

2. Log out. The doors will open and allow players outside your room to pull the mobs within.

Players outside the raid will need to complete the FATE, receiving the Aetherially Primed buff provided they fulfil the following conditions:

• They are Elemental Level 60 before the FATE concludes.
• They are within the FATE's boundaries when it concludes.
• They achieve a Gold Rating.

After the FATE, 8 Aetheric Nodes will appear around Hydatos, allowing addtional players to join the raid for the following encounters.

The Baldesion Arsenal: Expedition Support

• Dispel L is required to remove any personal buffs the Notorious Monster gives itself. Look for the casts "Mighty Strikes" and "Shock Spikes".

• Wind-aspected enemies have some slight innate evasion. Players can circumvent this via 2 Logos Actions:

  1. Feint L - Reduces an enemy's evasion.

  2. Spirit of the Remembered - Increases a player's accuracy.

Boss 3 - Absolute Virtue

Absolute Virtue is the first boss in The Baldesion Arsenal to introduce a hard enrage at 7:20.

Absolute Virtue is Wind aspected, so adjust your Magia board to Wind for defence and Ice for offence.

Wind-aspected Enemies

Wind-aspected enemies have some slight innate evasion. Players can circumvent this via 2 Logos Actions:

1. Feint L - Reduces an enemy's evasion.

2. Spirit of the Remembered - Increases a player's accuracy.

Absolute Virtue begins with the opening sequence:

1. Meteor - A raid-wide

2. Eidos - creates Light or Dark-aspected bracelets that surround its wrists, augmenting any future attacks that are of the same element. A buff based on the augmented element will also be visible on the boss.

3. Hostile Aspect - Several Light and Dark aspected AoEs litter the ground, but only one element will be augmented based on the boss's bracelets, suddenly growing in size before the cast finishes.

   As long as players stand away from the augmented AoEs, the unaugmented AoEs will never grow in size.

4. Medusa Javelin - A wide telegraphed conal AoE targeted at a random player.

5. Eidos

6. Impact Stream - Splits the arena into a Light and Dark side. Getting hit by the augmented element will result in lethal damage.

7. Auroral Wind - A small AoE tankbuster.

8. Eidos

9. Hostile Aspect

10. Meteor

11. Turbulent Aether - Several random players are tethered to a Light or Dark orb, spawning with a puddle of the same element under each orb.

    Tethered players must run and stand under a puddle of the opposite element to safely pop their orb.

12. Medusa Javelin

13. Auroral Wind

14. Meteor

15. Meteor

Absolute Virtue will then jump away, becoming untargetable and beginning the following sequence:

1. Explosive Impulse x3 - 3 proximity AoEs along the walls of the arena. Also spawns 3 clones of Absolute Virtue with active Light or Dark bracelets. These clones will each cast one Impact Stream.

2. Impact Stream

   To identify which clone is casting Impact Stream, players can follow the cut down the middle to a clone.

3. Impact Stream

   To identify which clone is casting Impact Stream, players can follow the cut down the middle to a clone.

4. Impact Stream

   To identify which clone is casting Impact Stream, players can follow the cut down the middle to a clone.

5. Explosive Impulse - A proximity AoE targeted on a player.

   Absolute Virtue will reappear at its location.

6. Medusa Javelin

7. Auroral Wind

From here, Absolute Virtue will enter a loop of attacks until it's defeated or it enrages at 7:20, adding in one new attack to the fray:

• Call Wyvern - Summons 2 Aern's Wynav adds, both Lightning aspected.

  These must be killed before they cast Explosion, a hefty raid-wide that also inflicts everyone with Damage Down.

Boss 4 - Proto Ozma

Proto Ozma is the final boss of The Baldesion Arsenal, constantly switching between forms that adjust both its auto attacks and available mechanics. It also has a hard enrage at 10:30.

Proto Ozma is Lightning-aspected, so adjust your Magia board to Lightning for defence or Earth for offence.

Below is a table with every shape Proto Ozma can take, along with the attack it executes after changing shape and the type of auto attacks.

Form	Form Shift	Auto Attacks
Sphere 🪩	Black Hole - 6 glowing buttons appear around the arena. Players must be standing on a button to avoid being removed from the raid. Additionally, each button must have at least one player on it.	Highest enmity target of each platform.

Pyramid ⚠️	Execration - Large Line-AoE down the platform.	Small AoE on a random player at the back half of each platform, inflicts a cleansable DoT.
Star ⭐	Mourning Star - PB-AoE centred on Proto Ozma.	Stack AoE on a random player on each platform.

   • Meteor (Stack) applies a cleansable Magic Vulnerability to all players hit.

   MTs should avoid the stack entirely, use all their defensives and stand on the right side of their platform, popping any orbs travelling towards their platform.

   Everyone else should stack towards the front left of their platform to avoid clipping the MT with the Magic Vulnerability.

   Failing this mechanic deals 90% max HP damage to yourself and anyone around you, severely crippling you and any others against any upcoming attacks.

   Players are suggested to step away from the party to resolve these to affect as little people as possible with the punishment.

4. Meteor (Proximity) - 2 players per platform for a total of 6 players are targeted with a placeable proximity AoE. Each proximity AoE also spawns an Arsenal Urolith, a Lightning aspected add that players need to kill.
