There are many secrets hiding below the surface in the partially sunken land of Hydro. If you dare to explore the expanses of the map while relying only on a few key abilities and no elemental energy, there is treasure to be had. A lot of it. Plus, you wouldn’t want to miss out on some of the most strikingly beautiful sights the game has to offer, right? So take a deep breath (or don’t, it doesn’t matter) and let’s dive right in.
How To Get The Ability To Dive
To be able to dive you will have tointeract with the Statue of the Seven in Fontaine. Any interaction with it will trigger a dialogue with Paimon where she says she feels a strange power emanating from the statue. After a couple more lines, a tutorial explaining theblessing of the Transoceanic Sourcewaterwill be triggered. From then on out you will be able todive throughout the entire Fontaine region.
You don’t have to resonate with Hydro to be able to dive.

The Basics Of Diving
The first thing to note about the blessing of the Transoceanic Sourcewater is thatyou cannot drown in Fontaine, even when swimming at surface level.
Your stamina bar will be replaced by anaquatic stamina bar whenever you are in the water. This bar works pretty much the exactsame way that regular stamina works when sprinting.

When you run out of stamina, you will immediately stop swimming fast whilethe bar takes a few moments to recharge. When swimming at a normal pace, the bar simply disappears.
There are a fewcontrols to know for diving. Keep in mind this will ultimately depend on your mapping and this is the default selection:

What Is Transoceanic Sourcewater?
Transoceanic Sourcewater refers toa little orb that floats alongside characters when they dive, presumably being the representation of the blessing that keeps them from drowning.
When triggered by using the corresponding control, awhiplash-like water rope will shoot out from the orb. If used against an enemy, it causes asmall amount of physical damage.

Characters with Arkhe energy alignment maintain it underwater, so their abilities can be used todisable underwater Clockwork Meks.
Using Transoceanic Sourcewater against aXenocromatic Creature allows you to absorb their abilities for a short duration, which is usually until you leave the water or switch abilities.

Underwater Combat Abilities
All party members will be able to use Transoceanic Sourcewaterupon diving. No extra actions are needed. However, this isnot the only offensive abilitya character may have.
There arespecial creaturesyou will find swimming about that lookdifferent from most Fontemer Aberrants. They areblue and glow dimlywith a symbol floating by them. These are known asXenocromatic Creatures.

Each one has aspecial ability with a unique effectthat you can temporarily adopt bydeploying Transoceanic Sourcewater against them. There are three types of creatures and corresponding abilities you can obtain.
Xenocromatic creatureswill not attack youon proximity or even after you attack them first. They cannot be killed, either.

Xenochromatic Armored Crab
Armored Crabs are small crustaceans with a sturdy shell that is both their home and their protection against predators. Though they are not particularly powerful creatures in battle, they do have pincers to counter-attack, balancing defense and offense to ensure survival.
This creature grants the ability tocreate shields that are able to withstand one or two attacks at a time, depending on the mobs' damage. It also allows you toattack with a small blast or deal a powerful counter-attack. It can be used in two different ways:

This ability can be used tobreak rocks and mineCondessence Crystal. It can also block the pressurized water from vents for a short duration.
Xenochromatic Blubberbeast
Blubberbeasts arelarge and round, peaceful creaturesthat just lounge about. They are mostly inoffensive, thoughthey will fight back when provoked, drumming on their bellies to generate shockwaves.
This creature grantsthe ability to use a sonarthat can bothcause damage and help you locate unseen objectsthat are buried beneath the sand at the bottom of the ocean floor. There are two ways to use this ability:

Xenochromatic Hunter’s Ray
These slick and elegant creatures seem to glide around rather than swim.They will generally not attack without reason, but if you get too close to them, they might find you threatening and engage in combat mode.
This creature grants the ability to unleash powerful water blades that deal big amounts of damage and have quite a long attack range. It is the only ability that has two charges. There are two ways to use this ability:

These water blades are also theonly ability that can cut through seagrass.
How To Heal While Diving
Since the abilities you can use underwater are very limited, you will need toresort to the environment to be able to restore health and energy.
You will be able to findsmall fish schools that glow with a faint green swirlthroughout Fontaine. These are called Recovery Orbs.
Swimming right through thesewill make them temporarily vanish,restoring a chunk of your health, and your aquatic staminaif it’s down. After a short wait, they willrespawnin the same positions.
Underwater Puzzles
The puzzles that can be found throughout Fontaine arenot very different from the puzzles you will find on land.
Most of them will belocked behindArkhe energy mechanics. However, you will also be able to findOusia and Pneuma blocksclose to the mechanisms.
The main difference between underwater and above water puzzles is that you will have torely on Xenochromatic Creature abilitiesto solve underwater puzzles very often. Some of the most common puzzle mechanics include:
