We show you how you can find, summon and defeat the three Hydras that we have roaming around the Core Keeper map.If you’ve already defeated all the main bosses in Core Keeper and want to go one step further, either because you want to platinum the game or simply because you liked it so much that you want to fight all the possible bosses , your next step is the Hydras, which we will talk about in this guide.

If you don’t want to walk all over the map looking for the three hydras in the game, you’ll have to make the scanner for each of them using the Ancient Hologram Capsule . Once located, you’ll need to build a series of organs using the Hydra Altar.

How to summon the three Hydras in Core Keeper

To summon each of the Hydras, you will need to build three key items , one for each of them. These can only be obtained after unlocking the Hydra Altar . Below is a list of the items and their descriptions.

How to get the Hydra Altar in Core Keeper

I’ll tell you right away that you’ll need to be far enough along in the game to have several solarite ingots around your base, since in order to start summoning hydras, you’ll need to have the hydra altar . This altar can be built using the solarite workbench .

The key material for this craft will be the Giant Bug Brain , which you can only get by defeating Ra-Akar , the Sand Titan.

Druid, the Savage Titan

The Druid is located in the jungle biome where we defeated Azeos and to summon her you will need the Nature’s Wind Organ , which you can craft using the altar we talked about just above. As a general rule, this will be the first hydra you face, so it will be the easiest.

His movements are quite predictable, as he only shoots a beam which you will have to dodge by moving as far away as possible and launches melee attacks . From time to time, he will let out a roar with which three platforms will fall from the sky, so you will have to be on the lookout to dodge. Also, a worm will roam the ground that will be as annoying as possible.

As a reward for defeating her, you will receive a wide variety of items, although as with all bosses, these can vary depending on your luck. In this list, we will leave you with all the ones that have a 100% probability.

Cryoidra, the Ice Titan

The Cryo-Hydra is found in the sea biome where we defeated Omoroth and to summon it you will need the Ice Wind Organ , which you can craft using the same altar as the previous one. Here the combat starts to get a little complicated, although it’s nothing that can’t be overcome with good equipment.

Its movements are similar to the first Hydra, as it will use the same melee attack and the beam, although now instead of platforms, a kind of ice rock will fall that will throw projectiles . Now, two heads will appear instead of one, although the second will be a ghost and you will not be able to hit it.

As a reward , you will receive a wide variety of items, although as usual, these may vary depending on how lucky or unlucky you are. In this list, we will leave you all those that have a 100% probability.

Pyrohydride, the Titan of Fire

The Pyro Hydra is found in the desert biome where we defeated Ra-Akar and to summon it you will need the Fire Wind Organ , which you already know where to make. Without a doubt, this Hydra is the most complicated of all, since it will have three heads , two of them phantom.

The movements will again be similar to those of the first and second Hydra, although it will also incorporate new mechanics, such as a charged attack which we will have to dodge by moving as far away as possible to avoid the impact of the roar. In addition, blocks of lava will also fall from the sky, although they will warn us of the location of the impact with red circles.

As a reward , you will receive a wide variety of items, although as usual, these may vary depending on your luck. In this list, we will leave you all those that have a 100% probability.
