Hydra (aka Serpent King) is a Boss in Dark Souls.


Hydra Information

 Situated in a shallow lake at the very end of Darkroot Basin and is also guarded by four Crystal Golem Guards. The Hydra is massive in size with 9 heads.



It has two main attacks:

  1. Each head can spit an extremely powerful water projectile that can travel a surprisingly long distance from it and is not affected by gravity. The range on these projectiles is so great that the Hydra often begins spitting them before the player can even see it clearly. The player should utilize all available cover when working their way up towards the Hydra, as the projectiles are numerous and very difficult to roll through. It should be noted that each water attack is PHYSICAL, not magic. So don't go into this fight thinking a magic shield will do you any good.
  2. At close range, each head will perform a quick melee type attack against the player.





  • Your main goals is to get in close to the Hydra and position yourself a bit into the water in the large lake that contains him. This will cause the Hydra to switch primarily to its less dangerous physical attacks. Be careful, however, as the safe zone inside the lake is quite small and there is a drop-off zone inside of it that you can fall into for an instant death. Once close, just keep up your shield - the Hydra's attacks are fairly weak and with a good shield like the Heater Shield you should deflect all damage. After each attack, simply locate one of it's heads and hack away. Rinse and repeat until the Hydra is defeated.
  • Range attack: There's a spot around the middle of the lake's edge where none of the Hydra's heads will attack. Find that spot and you can shoot with arrows or use sorcery. You won't even need a shield to block at all. The spells must hit a neck, a head or even the stump where a neck used to be, because the body itself is not vulnerable at all.
  • A good crossbow, such as the Heavy Crossbow located in the Depths, can be very effective once the player reaches the edge of the lake. A crossbow enables the player to still block with a shield between shots, and the Hydra can be target locked from quite a distance. Simply block the Hydra's bite attacks with a shield, and then fire crossbow bolts at its main body. Often the Hydra's heads or necks will interfere with the shot, resulting in even greater damage due to the close range.
  • Another way to kill the Hydra and take 0 damage is to equip the Dragon Slayer Great Bow and a Hawk Ring. Using the Darkroot Garden entrance, climb down to the last ladder, but do NOT climb down beside the waterfall. You can shoot him from the top of the waterfall without him using his spit attack.


  • The most convenient bonfire to the Hydra is usually the otherwise little-used bonfire at the bottom of Darkroot Basin, near the lone knight with a halberd, and the Grass Crest Shield. The bonfire is located in a tunnel near the knight, and allows for a fairly easy run back to the Hydra in the event of the player's demise.
  • Summoning (and PvP) activity in the Basin tends to be low, so the player should expect to take on the Hydra solo.
  • The water projectiles should be avoided at all costs. They do heavy damage and can travel a surprising distance. Try to stick around the trees in the level and keep moving, as they'll sometimes block the projectiles. You can also use the Crystal Golem Guards as shields, as they can be killed by the water projectiles. You will have to contend with the Crystal Golems first. They have strong attacks but move slowly. Use your shield and avoid their area of effect attack. A ranged weapon such as a shortbow or crossbow can also be used to draw the Golems out one at a time without triggering many Hydra projectile attacks.
  • The Hydra telegraphs both of its attacks - the physical attack is preceded by an easily distinguishable loud shriek, and about a second before firing the projectile attack the Hydra will suddenly jerk its heads around faster than normal (this one is a bit less obvious, but it is there.) This is very useful to remember when fighting at close range and blocking its physical attacks. If the Hydra has waited a bit longer than normal between attacks and has not shrieked, it is time to start running sideways and zigzagging as the projectile attack is probably coming.
  • The water projectiles are actually classified as physical damage. This means that individual water projectiles can be blocked with a high stability shield (albeit at significant stamina cost), but be wary of the other projectiles landing behind or beside you - they can still damage you and even knock you into more incoming projectiles. It is generally safer to try to avoid the projectiles or hide behind cover rather than try to block them in the open.
  • Bring as many Estus flasks as possible, ideally at least 10, and try to upgrade your flask to at least +3 prior to the battle. You may have to heal repeatedly before you can even get to the shoreline thanks to the incoming water blasts, and may only have time for a single flask between the Hydra's projectile attacks. Thus your Estus flask should be strong enough to keep you alive if you get hit by multiple projectiles and have little time to heal.
  • Try approaching from the left (the opposite side of Havel's Watchtower). You can get fairly close to the lake while the cliffs protect you well from the water blasts. Once you're close enough that you have to be exposed dash towards Hydra, because the downward slope of the shore will cause it to shoot its projectiles over your head. Get into melee range ASAP for an easy fight.
  • Obtaining the Rusted Iron Ring can lessen the difficulty of the fight as it allows you to walk through water without speed reduction.
  • Tip: While melee attacking the heads after they strike the ground, move beside them and do not stand under/behind them (i.e., between the head where it has impacted the ground, and the main body of the hydra). As the head withdraws for another strike, it can drag you backwards towards the Hydra and there is a significant risk you will then fall into the drop-off zone in the water and instantly die.

      "Safe spot"16 Jun 2016 22:36  

      Everyone know about the corpse next to hydra. It is recommended to bring a bow and Iron ring. My strategy is to get there and stay but not in front of it (due to the short spot before falling off). At least 2-3 heads will attack or hurt you so be careful but after cutting them, you should be safe. Use your bow to shoot him to death or use the iron ring to chop off other. He will switch to water attack if you get to the shore. I hope this will help other people who are having trouble with him.

        If you are planning to kill the Hydra in melee, while there are doubtless other methods, I find that Havel's ring coupled with the Rusted Iron Ring allows you to get into range quickly (mostly useful for getting to the 'safe zone' of the lake before it stops firing water projectiles) and move to slice the heads off and retreat back into the safe zone quickly. Another suggestion would be to use the Ring of Steel Protection (as all the Hydra's attacks deal this kind, thus reducing the chance of it getting a lucky kill).
