Great Serpent

Location Sunken Valley Passage
Reward 1st Serpent: Fresh Serpent Viscera
2nd Serpent: Dried Serpent Viscera

Great Serpent is a Boss in Sekiro: Shadows Die Twice. Bosses are special Enemies that feature their own arena, a large and prominent health bar, and a variety of unique moves and abilities. You will need to perform multiple Deathblows on them in order to defeat them, and filling their Posture Gauge is the only way to accomplish this. However, decreasing their health will make it so their Posture Gauge depletes more slowly, assisting you in accomplishing this feat.

While this description fits most bosses, the Great Serpent is more akin to an in-game event than a classical boss. You encounter two Great Serpents in multiple areas of the game and must progress through each encounter without dying in order to discover how to eventually kill the Serpent which first ambushes you. (The second Serpent, found near the Toxic Memorial Mob at the bottom of the Sunken Valley, is not killable). Each encounter with the first Serpent must happen in order, or the boss will never progress to its final resting place. As a boss, the Serpent shares similar mechanics to the Great Colored Carp  event/boss fight.



Great Serpent Location

Instead of one location, the first Great Serpent is met several times throughout the game. Though two of its encounters are optional, in order to kill the Great Serpent that first ambushes you, you will need to encounter it in the following order:

  • Ashina Castle Outskirts: While traveling to the Ashina Castle Gate Sculptor's Idol. (Not optional)
  • Gun Fort/Ashina Depths: Right after leaving Gun Fort, across the rope bridge. (Not optional)
  • Sunken Valley: Reachable later in game through Senpou Temple, Mt. Kongo. (Optional)
  • The second Great Serpent, which is found in a cave near the Toxic Memorial Mob merchant at the bottom of the Sunken Valley, is not directly related to the first and will stay alive even after you have killed the first Great Serpent. Encountering both Serpents, and killing the first, is required to unlock an alternate ending to the game when on the Immortal Severance path.

Strategy Write-up

  • 1st Encounter: If you move through the grass, during your first encounter with the Serpent, you can avoid been caught by it while on your way to the abandoned palanquin. Once you find the palanquin, enter it and wait until prompted to deliver a deathblow to the eye of the Great Serpent, which will cause it to flail about in pain--careful, it can still hurt you!--and allow you to escape.

  • 2nd Encounter: Stick to the reeds/plants in the water while swimming toward the the far edge of the lake you've fallen into. There are patches of reeds/plants which will allow you to stealthily hide from the Great Serpent while it's looking for you. With enough health, you can brute force your way swimming to the opposite side of the lake, or take the much safer route of swimming from stealth spot to stealth spot until you reach the opposite shore.

  • 3rd Encounter: After gaining the Puppeteer Ninjutsu, head back to the first Sculptor's Idol for Senpou Temple, Mt. Kongo. Exit the shack and head toward where the Kite mechanism is nearby, then perform the Puppeteer Ninjutsu on the Rat enemy just before the kite. Your new puppet will unwind the Kite and keep it floating for you, which will then allow you to use it as a grapple point from the tree next to the first temple past where the white and red pinwheels and the Old Hag NPC are located. Use the new grapple point to get to the previously unreachable area across the ravine, then climb up to where the Sunken Valley Cavern Sculptor's Idol is. Past this point, you will be able to jump from a nearby wooden plank onto the head of the Great Serpent resting far below you; simply deathblow it twice to kill it, as it does not fight back.

  • Optional Encounter: The second Great Serpent can be found in a cave just behind the Toxic Memorial Mob. You must use the Puppeteer Ninjutsu on a lone, frightened Monkey near where you find the Serpent in the back of the cave in order to distract it, then run past when its not looking at you in order to grab the item it guards. You cannot kill this Serpent, and it remains alive even after killing the first.

    • Alternatively (1): Getting the item this particular Serpent is guarding can be achieved without use of the Puppeteer Ninjutsu by doing the following--grapple onto the ledge where the Serpent is, then fall immediately after so that you dodge the attack. Grapple back up to the ledge again while the Serpent is recovering from its attack, then sprint away into the house.
    • Alternatively (2): Run towards the serpent and quickly make use of  Mist Raven  when she attacks you. Then sprint into the house.

        I have made a discovery. The first serpent does not come back, once you triggered a fight with Gyoubu Oniwa. I did not stab it in the eye while in the palanquin.

          There is only 1 snake. Check out the eye of the one in the cave, it's clearly bloody. And when u get swallow by it after gun fort it just withdraw to its lair and***** you out. There maybe a continueity error?

            I think it's pretty stupid that both serpents look the same. How hard is it to open photoshop and fiddle with the hue thingy for a few minutes, jeez.

              If you don't perform the second deathblow when you jump onto the snake in the sunken valley, it transports you to the snake cavern near the Toxic Memorial Mob

                What happens if you don't go into the palanquin and don't stab its eye? Will it be resting in the Sunken Valley, perhaps without a bloodied eye?

                    Interesting thing to note: If you don't kill the first serpent when doing the plunge attack, it will swallow you and bring you to the entrance of the cavern with the dried serpent viscera. Shocked me when it happened by accident. You discover something every day.

                      Anyone knows if something happens when you decide to stay in the Palanquin instead of stabbing the snake in the eye?

                        Just wanna note that the Fresh Serpent Viscera is NOT the heart of the Serpent but its liver. It's mentioned by the divine heir I think. Anyway it makes me think that it didn't really get killed by Sekiro.

                          There appear to be at least two serpents; one unharmed near the Dried Viscera and the other with a gouged out eye. Also all the statues of a Woman embracing a serpent in the Sunken Valley and near the first staff wielding monk in Senpou Temple seem to refer to the act of becoming a Cradle. The Large Fan also seems to connect the statues, Sunken Valley and Senpou Temple.

                            Thought I was being clever when I killed the boss and then went to get the dried fruit, only to see the snake still there. I thought there was only one.

                              After Stabbing it's eye in the first encounter, the snake basically completely ingored me after the gun fort. I'm not sure if it's because she was blinded in that eye and didn't see me, or if it was the Gachiin's Spiritfall I was using at the time (this was done in ng+)

                                Everyone who felt of the bridge after killing the snake dont worry you can get the items anyway well it is true you cant go back up there but you can buy the items from the little chest at the sculpturers place next to your immortal training partner

                                  You can get past its first encounter by either doing a very lucky dodge, resurrecting or using Ungo's Sugar to reduce damage taken (I'm in ng+ with 9/10 beads, but also bell and without charm active, so idk how feasible it'd be on a first turn) - Just get to the palanquin via stealth and there start running over, it'll try to eat you once but not follow you aimlessly as it does when you half-blind it. I don't know if this can have any consequences, I'm just writing this so that more people can look for those

                                    So i have a little theory that i wanted to share. On the Sekiro wiki there is written that there are 2 great serpents but i don't think that that is correct. I think that there is actually 1 Serpent that have 2 heads, one on each end of it's body. Some arguments 1: After you stab its eye and look on it while you are in the cave you can see that its running away backwards. ( and i don t think "normal" snake would do that") 2 You never see the end of its boddy 3 in the sekiro lore it's told that some people worshiped the Snake God and i m preatty sure that they would realize that theri is more of there gods 4 After you plunge attack its head its body is laying on the mountain but after a while it dissaperd so i suspect that the "other Half of Snake has pulled it to itself. ( it's not some super serious theory just a random stuff that i have come up with while playing the game over and over again)

                                        After you kill the snake, by any chance, don't go to the bridge to look around, cause you will fall, and there is no alternate way back, than killing the nope.
