There’s a Hypostasis for every element now, and even though they provide similar challenges, they can’t all be defeated in the same exact ways. If you’re having trouble with this boss, we’re here to help. Here’s a guide on how to get to the Hydro Hypostasis and beat it in Genshin Impact.
Genshin Impact Hydro Hypostasis Guide
How to Get to the Hydro Hypostasis
First off, this boss is actually a tricky one to find even though it’s clearly marked on the map. It appears to be floating on the ocean, but it’s really in an underground/undersea cavern in the Suigetsu Pool area of Watatsumi Island. This is the exact spot on the map where the entrance to the cavern is located:
Look for a waterfall near the shore that leads down below the ground. It’ll be slightly hidden by a cliff face and a few plants, but it should look like this location in the picture below:
How to Beat the Hydro Hypostasis
You should have a bit of an idea of what’s to come if you’ve fought the previous Hypostasis bosses. This one summons other enemies, uses large AOE attacks, and can heal itself as well.
It goes without saying, but don’t use Hydro for DPS here. Instead, pick Cryo, Pyro, or Electro characters to deal with the Hydro shields that enemies will have. Aim to trigger Vaporize, Frozen, or Electro-Charged elemental reactions here.
Some of the best DPS options to take advantage of those reactions are Ayaka, Hu Tao, Ganyu, Diluc, Yoimiya, Keqing, Razor, and Yanfei. Characters like Diona, Qiqi, Bennett, and Xinyan can also create shields and/or heal while causing reactions as well. Barbara and Kokomi also work here strictly for healing. There are plenty of options for this one.
The Hydro Hypostasis will usually attack with huge splashes that deal damage if you get too close. Whenever it transforms into dolphins, a big splash is coming. The dolphins will either dive directly at you, or nearby to block your movement. Simply run away while they’re in mid-air to avoid damage.
The boss will also split into two separate slime-like Water Droplets — a darker one that moves toward you to explode, and a lighter one that sends healing orbs to the main body. Use elemental attacks to destroy the darker one before its explosion to expose the Hypostasis core. you can also intercept the healing orbs to use them for yourself, or destroy the light Droplet in the same way as the dark one.
Outside of those moves, the Hydro Hypostasis will also cause damaging rain to fall randomly on the platform, transform into a vortex like the Pyro Hypostasis, and even summon large rolling waves that start from the perimeter of the platform and move inward.
After almost every single attack, the boss’s core will be exposed and that’s your chance to deal high elemental damage through reactions — especially during/after the attack when it surrounds itself in a ring while staying still, much like the other Hypostasis bosses.
Once you’ve dealt enough damage, the familiar little Hypostasis healing mini-game begins. Three Water Droplets will start at the edge of the platform and slowly move toward the boss to heal it. Destroy all three of them with Electro, Pyro, Cryo, Anemo, or Geo attacks to end this boss fight.
Be sure to do this part quickly too, since the fight continues if the boss gets healed by even one of the Water Droplets.
