Hydras are minibosses in Dark Souls.


A Hydra can be found at the bottom of Darkroot Basin and another is found close to the entrance to Ash Lake.


The Hydra is a large sea monster with a body similar to a plesiosaur, but with tentacles underneath a shell-like structure and several long necks and heads. Each head can fire blasts of water from a distance or lunge into the ground for a close range attack.


The Hydra can be defeated by severing its heads or by targeting the main body and using ranged attacks.

As the player moves closer to the shore, the Hydra will almost exclusively use its head strikes. After it lunges toward the player, each head will bury itself in the ground for a short time, presenting an opportunity to sever its vulnerable necks. As each head is defeated, the spread of the Hydra's attacks will diminish, making it easier for the player to finish the job.

The lunge attacks can be blocked or dodged. Certain spots can be found where the heads will completely miss the player. If the Hydra's position does not change, these spots can be exploited throughout the battle.

Darkroot BasinEdit

The Darkroot Basin Hydra rests in a deep pit beyond an otherwise shallow pond and hardly moves at all. By wearing the Rusted Iron Ring, mobility will not be an issue throughout the fight, although care should be taken not to walk too far into the lake, risking a sudden death by sinking into deep water, either it is by human mistake, by being pulled in by one of the Hydra's heads while it is retracting, or by being launched in by the area of effect blast unleashed by the water projectiles.

Crystal Golems in the area can be damaged by the Hydra's water projectiles.

As the player approaches the Hydra at a distance from its front, the slightly elevated area on the left, from the player's perspective, is almost completely safe from the water projectiles; however, they are relatively easy to block. Although the player is relatively safe from health and stamina damage when blocking, the water projectiles can still deal substantial stamina damage through the shield. Alternatively, equipping the Ring of Fog will allow the player to approach the Hydra much closer. The monster will still start shooting projectiles, although at no specific direction until the player gets too near.

While using a hit and run method, players can utilize the rock and tree near the edge of the water as cover from the water projectiles and head strikes. After the Hydra thrusts its heads into the ground, hack at one of the necks until the head is severed. The last head, which is usually inaccessible for melee players, will repeatedly swing over the deep water area, causing it to always miss the player. The head can be dispatched with ranged attacks. A few shots will quickly sever the head and defeat the Hydra. Alternatively, the last head can become accessible if the Hydra's position is shifted by running along the water's edge.

Ash LakeEdit

The Ash Lake Hydra rests near the edge of a sandbar entering the lake. Some distance from the Hydra, a large log lies on top of a ridge of the sandbar. Sheltering behind this log will attract long range attacks from the Hydra, which will be blocked completely by the log. It is possible to shelter behind the log and attack the Hydra safely with a bow; the Hawk Ring and Dragonslayer Greatbow are recommended. When the Hydra is already at very low health, the Symbol of Avarice and Covetous Silver Serpent Ring can be equipped to increase the number of souls gained when the Hydra dies. Equipping the Symbol of Avarice will mean shooting blind, but the Hydra is so large that it is easy to continue hitting its body (it is not necessary or advisable to aim for the heads), for the last few shots required to kill it.

For melee based characters, one of the major danger while confronting the Hydra is actually reaching up to its location, as that would mean having to evade or block the constant barrage of homing water shots. Wearing the Ring of Fog allows the player to approach the Hydra without issues, to the point that it will only become hostile once the player is right in front of it, having a melee based fight for the most part from the beginning. Unlike the Hydra fight in Darkroot Basin, the waters of the shore where this battle takes place is shallow enough, so mobility will not be an issue throughout the fight.


  • When moving closer toward the Hydra in Darkroot Basin, tilting the camera higher will help identify the dark areas from the shallow side. Venturing into the deep end will cause the player to abruptly sink, as one would fall from a cliff, resulting in an instant death.
  • It is possible to shoot off the Hydra's heads from Darkroot Garden, though it may require many arrows and a long range bow. The Black Bow of Pharis makes a good choice for this, if the player has the stats to wield it, as it can be found on the way to the pass overlooking the Hydra. May require the Hawk Ring for further range.
  • Regardless of how much remaining health it has, if all of a Hydra's heads are severed it will die instantly.
  • Resting at a bonfire will cause the Hydra to regenerate its lost health, but any heads which have been severed will remain that way.
  • If one continues through the Ash Lake without defeating the Hydra, it will attempt to follow the player. Once the player passes the area where the Giant Clams are, the Hydra will jump out of the water and fly across the beach to the other side to continue to pursue the player. It will then follow all the way to the archtree at the end, making confrontation with the Hydra basically unavoidable.
    • If the player attempts to double-back to the entrance to the Ash Lake, the Hydra will once again jump out of the water and fly back over to its original position.
    • While flying over the beach, the Hydra will bombard the area below it with water projectiles.
    • This is the only time that the Hydra's body can be clearly seen in its entirety.

  • Since they drop Dragon Scales when defeated, the Hydras could possibly be descendants of the Everlasting Dragons.
  • In Greek mythology, the Hydra was a serpent-like, multi-headed water beast. Various accounts of the creature claim that for each head that was severed, one to multiple more would sprout in its place.
