How to acquire items to upgrade
Hydatos Crystal: These are acquired by killing Notorious Monsters in Eureka Hydatos. The higher level the Notorious Monster, the more crystals it will drop. While fewer crystals are needed compared to prior steps, Notorious Monsters in Hydatos also drop fewer crystals. A good source of crystals is the FATE 
The Baldesion Arsenal: Expedition Support, although this only spawns when there is an ongoing run of 
The Baldesion Arsenal.
Crystalline Scale: 3 scales will drop each time you complete the FATE Crystalline Provenance with gold medal credit in Eureka Hydatos, which requires you to kill the notorious monster Provenance Watcher. This is the only way to obtain the item as they are not sold by the Expedition Birdwatcher.
Physeos Weapons
An upgrade to Eureka weapons. Stats and appearances are identical to Eureka weapons, except that they have extra Elemental Bonus stats that increase the weapons' power in Eureka zones only (including The Baldesion Arsenal).

How to acquire items to upgrade
Eureka Fragment: These are exclusively acquired inside The Baldesion Arsenal. A complete clear yields 28 fragments total, with each boss defeated dropping a portion of that total amount. It requires a total of four runs, assuming all of them are successful, to obtain enough fragments for one weapon.

Notorious Monsters
Players may encounter notorious monsters that cannot be found in other regions of Eureka. Those who would engage them are advised to seek aid from other adventurers.
Defeating notorious monsters yields a great deal of elemental EXP, as well as various rewards.
The Baldesion Arsenal
The Baldesion Arsenal is a brutally difficult open dungeon that can be challenged by up to 56 players at once. To enter, you will need to complete the main Eureka storyline and prepare for the worst.
The entry requirements for this duty are extremely strict, as savage bosses, devious traps, and an effect that prevents resurrection by certain means all await you within.
Those who hope to challenge this dungeon should read all available information thoroughly, and properly understand the risks before entering.
Entering the Baldesion Arsenal
Aetherial nodes throughout Hydatos can provide access to the Baldesion Arsenal.
To make use of these nodes, your elemental level must be 60. You will also require a particular status enhancement.
Aetherial Nodes
There are two varieties of aetherial nodes: unstable blue nodes, and stable red nodes. Regardless of type, each node will disappear once accessed by a player, or if a certain amount of time passes without its being accessed.
- Only the player who accesses a node will be transported, even if that player is in a party at the time.
The appearance of aetherial nodes is related to the atmospheric condition umbral turbulence.
Unstable Aetherial Nodes
An Aetheric Stabilizer is required to use unstable nodes. Aetheric Stabilizers can be acquired in Hydatos through various means, and will be consumed once they are used to access a node.
Stable Aetherial Nodes
Stable nodes do not require the use of Aetheric Stabilizers. However, each will only appear after a certain amount of time has passed following the disappearance of an unstable node.
Resurrection Restrictions
The detrimental status effect "Resurrection Restricted" will be applied upon entering the Baldesion Arsenal. While this status is active, you can only be resurrected via limit break or a specific logos action. For this reason, be aware that KO carries a heavy risk.
Withdrawal and Re-entry
If you use choose the Return function from the menu, or accept the prompt to return to the starting point while KO'd in the Baldesion Arsenal, you will be removed from the dungeon and transported to the expedition camp in Eureka Hydatos. To re-enter the dungeon, you will once again need to access an aetherial node, so think carefully before returning.
Rewards
- Main article: The Baldesion Arsenal#Loot
Those who defeat the bosses within and clear the entirety of the Baldesion Arsenal will be richly rewarded. To do so will be no mean feat, however─you must communicate well with your fellow adventurers if any of you are to reach the prize.
