Eureka Hydatos is the fourth and final Eureka Instance. The main weather affinity of the instance is Water and the zone boss to get the last material for the weapon from is Provenance Watcher.
Once elemental level 60 is reached, you can unlock The Baldesion Arsenal.
Getting Started
Once the story of Eureka Pyros has been completed, you will get the quest "And We Shall Call It Hydatos" which leads you back to Rodney at Pier #1 in Kugane. Here you will unlock the next step of the Eureka Journey: Eureka Hydatos.
When entering Eureka Hydatos via Rodney, you will find yourself in the base camp of this zone called Central Point. Once again, various NPCs can be found here, as well as the main Aetheryte.
Just as in Pyros, monsters are able to mutate or adapt, for significantly more EXP gains and for possible drops of Moisture-Warped Lockboxes.
Traveling across Hydatos
Since Patch 5.1 you are able to ride mounts in Eureka from the start, which makes traversing the lands a lot easier.
Upon reaching level 51, you will be able to attune to the Aetheryte on the southwestern side of Hydatos, called Unverified Research. At level 55 the eastern Aetheryte The Dormitory will become available and complete all connections.
Just as in previous zones, Aetherytes can be used to travel between them, but they cannot be ported to via map or Teleport-Menu. However, using Return will bring you back to Central Point.
Hydatos' layout characteristic is that, western side of the zone is filled with lower level mobs (51 to 59), while eastern side of the zone is filled with higher level mobs (60 to 65). Southernmost side of the zone is completely devoid of mobs, so it can be used to travel safely (especially if you are trying to get to aetherytes). Travelling across Hydatos is much easier compared to previous zones as it is a flat zone, and you don't have to pass through narrow corridors, hallways etc. filled with mobs to get to somewhere.
NPCs
Expedition Chronicler
Upon talking to this NPC, you will be able to get summaries of the Eurekan Expedition, which brought you here in the first place. As you progress through the zones you will be able to unlock more and more records of the expeditions. Once unlocked, you will find information about The Baldesion Arsenal in here too.
Gerolt
Well known from previous relic weapon and armor questlines, this NPC gives you information about and lets you upgrade your Anemos weapons with crystals and materials collected from the zone. The table shows which items are needed for which step, please note that the weapons vary by name and prerequisite depending on job.
The weapon will be upgraded through all zones, which means if you want to reach the Eureka or Physeos stage of your weapon, you have to upgrade it all the way through Anemos, Pagos, Pyros and Hydatos.

Choose between Krile's path (sealing) or that of Ejika Tsunjika (destruction) for another cutscene. Return to Central Point and talk to Ejika Tsunjika (when doing Krile's path) or Krile (when doing Ejika's path) to complete the quest.
You can now talk to Expedition Scholar and unlock The Baldesion Arsenal.
Fates
All Fates in the Eureka Instances are Notorious Monsters (NM). Usually those fates are spawned by defeating a specific enemy or enemy type and if at least 120 minutes have passed since the Fate was last active. Some Fates have specific conditions which have to be met in order to be spawned, or the monsters which are needed to spawn the fate might have conditions as well. A map of all Fates in Eureka Hydatos can be found to the right side of this text. The completion of Fates in Eureka Hydatos will reward the player with Elemental EXP, Hydatos Lockboxes and Hydatos Crystals. Some Fates have added special drops like extra magicite items.
To keep track of the instance and the Fates within, it is recommended to use a so called Tracker. Not only does it make the coordination of an instance easier but it will also help to check quickly, which Fates can be spawned, which ones will soon be spawnable and which conditions will be met soon.

Bunny Fate
Just as in Pagos and Pyros , Bunny Fates exist in Hydatos as well. These Fates always involve saving Happy Bunnies from imminent danger. While fighting the Fate, the bunnies will help the player in one way or another, by healing them or spawning AOEs which will give a damage buff. Once the Fate is defeated and a Gold Rating is achieved, the player will have a bunny following them, which will eventually lead them to a treasure, when interacted with a Lucky Carrot. When the Carrot is used, you will receive a prompt, which wants you to move into a specific direction and once reached the location, a treasure will be unveiled. These treasures can have mounts in them, along with some other things.
Other than Notorious Monsters, these Fates do not have to be spawned by killing enemies. The Fate will spawn after a set timer once all Bunny Treasures from the previous Fate have either been found or the bunnies have been discarded or killed.

Zone Boss: Provenance Watcher
The last Notorious Monster of Hydatos is Provenance Watcher aka PW, which will drop Crystalline Scale in order to upgrade your relic weapon to Eureka Weapon version. You will need 5 Crystalline Scales in total to upgrade your weapon, and you need to be at least elemental level 59 to get the drop.
Boss abilities
He starts in fire element, but later changes to ice. It’s good to start the battle with /magiaauto macro, or remember to switch elements as he changes. (REFORGE is when he switches)
- The Scarlet Price: A single target tankbuster.
- The Scarlet Whisper: Frontal cleave, basically he pukes fire in front. Move to the sides/behind
- Ice and Levin: Boss will call down little AoE's. Dodge them and go inside his hitbox.
- Ice and Wind: Boss summons ice spikes and bigger aoes that do wind damage and blow you up to the air . Avoid all.
- Diffractive break: Raidwide AoE, proximity-based so go a bit further.
- Hot tail: A big line aoe from the front and back. Move to flanks (he does it twice in a row)
- Akh morn: A hard, multi-hitting tankbuser, can be shared.
- When he flies away, look where his copies are, they will run through the arena in a straight line. You can hide on the bridge outside of fate bounds, or find a safe area.
Hydatos Loot Table
Just as previous zones, Hydatos also has potential goodie drops from lockboxes, FATEs(NM), and random mob kills. For each FATE(NM) completion, you will get Hydatos Lockboxes as a reward. For higher level mutated mob kills, you will get special lockboxes called Moisture-warped Lockbox with additional loot drops. You can exchange these boxes to Expedition Lockpick in base or R'ghonati in Kugane at Pier #1. Some of the FATEs(NM) have rare drops from bosses as well.
