Seath the Scaleless is a Boss in Dark Souls Remastered.


Seath the Scaleless Information

Envy and bitterness; words used to describe Seath's betrayal of his own kind; for unlike his brethren, Seath was born without the stone scales of the Everlasting Dragons. But with the help of Gravelord Nito and the Witch of Izalith, and Gwyn, the Lord of Cinder, Seath brought his own race to the brink of extinction, with many believing him to be the last of his kind.

As reward for his service, Gwyn anointed Seath the title of "Duke" and gave him permission to build a grand archive where he could continue his research into his long held desire for immortality. This archive would come to be known as "The Duke's Archives". Along with these gifts, Gwyn also bestowed a shard of his Lord Soul upon him.

After much research, Seath finally achieved his goal of immortality through the discovery of the Primordial Crystal. However, the discovery did not come without a price. As the albino dragon delved deeper and deeper into his research, his mind began to fade, and by the time he had achieved his goals, he had descended into madness.

Becoming more and more paranoid, Seath locked himself away in the archives, fearing the other lords would attempt to steal his immortality for themselves. Barricaded within the archives, he sent his Channeler servants far and wide across the land to kidnap fair maidens and the undead for his experiments.




  • 60,000 Souls
  • Bequeathed Lord Soul Shard
  • Humanity
  • Moonlight Greatsword: Attacking the tip of Seath's larger rear tail (not the smaller side ones) will eventually cut it off, giving the host the sword automatically. Players must attack the tip of the tail and not the base. 


Cursed Crystal Breath

Seath breathes a white mist in a circular arc, directly in front of him. This mist triggers a mass of crystals to protrude from the floor, wherever the mist touched. This can be dangerous as the initial breath deals magic damage of its own, while the follow up crystals build up your curse - this is the case for any crystals that he raises from the ground. A telltale sign that this is about to happen is his head drops slightly, to his left. This is an imminent sign of the cursed crystal breath attack, so roll backwards to avoid any form of damage.

The second variation of this attack is the same, but with a larger radius. However, due to the range of it, the sign that it is imminent is clear and takes a bit longer. Seath throws his head back for a second, then sweeps his head from side to side. When you see his head swing up, bolt it, or get behind him.

The final variation on this attack is instead of throwing his head completely back, Seath winds it while still facing forward - think of it as preparing to header a ball in soccer - and blows a straight line of white mist. He starts directly below him, and follows through, for quite a large distance. When you see this, just run to the sides.


Crystal Explosion

Arguably his most deadly move, when you see Seath curl up, run for the hills. Create as much distance as you can from the white mist that forms around him, as he's about to let out a great explosion directly in front of him. This explosion is then quickly followed up with a mass protrusion of crystals in the white mist area. This attack deals a combination of physical and magic damage, and cannot be blocked.


Tail Attack

If you stay around his tails too long, Seath won't stand for it. Instead, he raises his largest tail - which should be the telltale sign for a tail attack - and slam down with all three of his tails all around the area. He can do this a few times, and getting caught will result in your death as it can stunlock the player. Seeing as you probably are trying to get the Moonlight Greatsword, you should see the sign, and since you need to attack the tip of the tail to do so, you can easily get out of range of this attack by rolling back.

Alternatively, he has a second variation on this attack in which after lifting his tail, he still slams it down but only to begin sweeping with all three tails. This is arguably harder to get out of the way of, as the tails are always grounded. Use the same preventative measures as with the other variation.



He's had it with you, Seath ain't taking your smack anymore. He raises either hand, and lays down an open-palm smack, dealing seriously physical damage. When the hand is coming down, roll in the direction it's coming from (left or right) while moving away from Seath.



The cutscene only triggers when the host player moves into the area. If you have summons with you, give them time to run forward and position themselves near the crystal before you enter the room. Once Seath enters for the first time, he will block off the entrance, leaving you and your summons closer to the crystal.

First Encounter

Meet Seath for the first time after taking the second elevator in the Archives and continuing up an increasingly-crystalized corridor, that ultimately leads up to Seath's fog gate. This is where your 0 deaths attempt comes to an end, as to progress, Seath needs to kill the player. Souls and Humanity will be lost upon death, unless a Ring of Sacrifice/Rare Ring of Sacrifice is worn - we highly recommend to equip one as this next section presents you a couple of challenges that may result in your death. 

Go gently into the night; delaying the inevitable will result in not only your death, but being cursed as well. So make it easy for Seath this time, so you can eventually return, and give him a proper fight.

The player will respawn inside the Archives Tower after being defeated, locked up in a cell in the Archive Tower Prison.

However, if you choose against equipping a Ring of Sacrifice/Rare Ring of Sacrifice and managed to complete the Archive Tower Prison without dying, when you return for your second attempt at Seath, you will find your bloodstain in the boss room.


Tips, Notes & Lore

  • Though he was never an immortal, Seath is nonetheless still a dragon, and as a consequence of that greatly susceptible to Lightning Damage.
  • The miracle Great Magic Barrier is very effective against the magic damage dealt by Seath's crystal breath, but it does nothing against Curse buildup
  • Seath is blind, as noted in the description of the Helm of the Channelers, as a consequence you can use Slumbering Dragoncrest Ring or the sorcery Hush to make yourself undetectable, but that will not stop him from responding aggressively to all of your attacks.
  • After starting the battle, re-enter the room of the first encounter to find a Large Magic Ember and a valuable Soul. The room may contain a hostile, insane Big Hat Logan if you previously saved him from Sen's Fortress and then from the Duke's Archives. You must also have purchased all of his magic spells while he was in near the moving bookcase. After becoming hostile, Big Hat Logan will be naked aside from his hat (the rest of his gear may be obtained from a chest located in the room behind the moving bookcase, where you spoke to him before to purchase spells), suggesting he is attempting to mimic Seath's "scalelessness".
  • The name "Seath" appeared before in Fromsoft's King's Field games.
  • Watch out for the clams before the fight the first time you enter his arena, it is possible for them to enter the arena, push you around during the cutscene causing your starting location to be different, and then fight you during the boss fight. (could not insert a link, it would become a blank space)

Easy Way to Get the Sword

  1. Make sure you have no armour. (Or have less than 25% Equip Load)
  2. Approach Seath directly from the front.
  3. Immediately after he begins his melee or vertical crystal breath, make a break for his tail.
  4. Seath's animation can be quite lengthy, giving you a short amount of time to get a hit or two in.
  5. Don't bite off more than you can chew. If you don't think you'll make the strike, or if he begins doing his AoE crystal storm, or if he raises his tail to slam down on you, back away immediately.
    • For optimum maneuverability, lure Seath into the center of the chamber.
    • If you have summoned someone, have them stand in front of Seath, distracting him (while they try to do a minimum of damage). This should keep him distracted long enough for you to cut off his tail. Remember step 5, though, and be careful if Seath starts getting ready to attack with his tail. 

Second Encounter

This encounter allows you to enact your revenge on Seath, for the injustice of the first. To do this, you must venture through the Crystal Cave, and find him at the end of the area, past an abundance of invisible walkways, Man-Eater Shells, and Crystal Golems. Unlike most other boss areas, Seath's area will lack a fog gate, the first time you enter from the Crystal Cave which allows the Man-Eater Shells to enter the area making it a tougher fight; however they can be damaged by Seath, and in the event that you do die, the next time you enter the area and every subsequent attempt, a fog gate will be present to block Man-Eater Shells from entering the boss' arena. Past the Man-Eater Shell area, you'll find another spacey area with a number of statues of cursed players standing in low, glowing mist.


Make your way across the area to trigger the cinematic that will show Seath the Scaleless make his grand entrance, but not before emphasizing the crystal at the end of the room; this is the Primordial Crystal, his immortality. Destroy it, destroy his immortality. Alternately, if you are entering a second time, you'll be required to run around Seath to reach it, but don't be too worried as it will break on one hit.

Unless you have already been defeated by Seath before, do not break the Primordial Crystal immediately. If he is entering for the first time, wait for him to move forward into the middle of the room, first. If you break it too early, he will spend most of the battle right at the area's entrance, and his tail will clip through the walls. This makes it extremely difficult to acquire the Moonlight Greatsword, and exposes you to much greater risk from his physical or breath attacks when trying to get behind him in close quarters.

  • It is possible to kill Seath without destroying the crystal yourself. If you would like to add insult to injury, wait for Seath to reach you, then circle around to his tail. He'll most likely attempt an attack on you but will destroy his crystal, reversing his immortality and becoming momentarily stunned, which gives you a small window to get free hits on his tail. 

Numerous strategies will be effective against Seath, as he moves slowly and can be target locked from very far away. Ranged weapons, spells, pyromancies, and miracles are all effective, as are melee attacks on his appendages. During your first battle with Seath, it is recommended that you do not rush him, but instead observe him to get a sense of his attack patterns and vulnerabilities. The boss area is quite large and it is usually trivial to stay out of range of his breath attacks until you decide to commit.

Specifically, staying off to either the left or right of Seath will allow the player to take him on quite easily. Just continue to hit his side tails until he lunges down to hit, then roll or block to get away and face his front. When Seath goes for a frontal attack, move to his side again and attack. Repeat these patterns until he is dead.


Pyromancers & Mages

Continually circle him while locked on and cast your best fast spells such as: Great Chaos Fireball, and Crystal Soul Spear. It is unlikely he will even hit you, If he does, continue to circle and Heal when behind or beside him. He is very susceptible to spells and pyromancies, and the ability to lock onto him from afar means such spells may be used quite safely.



The Paladin Set, the Dingy Set, and the Antiquated Set, all have high resistance to curse build-up. Holding extra humanity can also greatly increase resistance, however it's up to you to weigh the pros and cons of using this in a high risk area like this. If you have low curse resistance, you may want to equip the Cursebite Ring before the battle. This will help slow the curse if you do happen to get stuck in his crystal field. If you get caught in it, roll out of it ASAP. Finally, if you become stuck in one of Seath's crystal fields, keep your shield up as you try to escape. This seems to reduce damage and possibly curse buildup, and you will see stamina drain as if you are continually blocking damage.

      Constantly circling him at medium range works very well. It baits his lazor/crystal attack that will always miss you by just running to the right, leaving his side tail exposed and enough time to hit it at least 6-7 times. Cutting his big tail off (if you want the weapon) is the hardest part. He can sometimes do the tail slam immediately just from you going near it, so watch out for that and roll well away as the tail slam can repeat.

        Just asking, would a +5 Chaos Zweihander, or a +5 Lightning Zweihander do more damage to Seath? Asking so I can do less farming between him and the Four Kings.

          Part of the reason the second half of Dark Souls just doesn't feel quite as epic. This guy should be one of the greatest badasses in the world. One of the last Everlasting Dragons, granted a Lord Soul shard by Gwyn, and spent countless years experimenting and studying the mysteries of the soul, crystal, and magic. His boss fight is pretty easy and most people only remember that cutting his tail was kind of a pain in the ass. Lore wise, bosses like him and Nito should be way stronger than O & S, yet they're somewhat of a joke.

            Nowhere in the game is it stated that Seath built the archives. They were granted to him. There's heavy evidence that the archives belonged to a craftsman deity who either died or departed from Anor Londo. This wiki is infested with speculation.

              Cosplay: Moonlight Greatsword, Tin Crystal catalyst, White dragon breath (and possible other crystal sorceries), Dragon torso stone. It will become Seath 2.0

                FINALLY got this bastard's tail with my sorcerer! What worked for me was a crystal halberd with crystal magic weapon on it, used two handed. With that even my wet noodle sorcerer was able to do decent melee damage. I wore the cursebite ring and lingering dragoncrest ring to increase the weapon enchant time. Took about three tries with that combo but I did it.

                  Funny how Seath is an easy boss, but when a 100%er tries to get all the weapons in the game, Seath becomes super tough guy because of his f***ing tail!

                    Poor thing only wanted to live forever, but went insane in his search for it, now you have to put him out of his misery, one of the last dragons in existence. Feels bad man :(

                      By far, the easiest boss in the game. I didn't use any Estus and wasn't even using a shield (holding a +14 Zweihander on two hands). The real deal here is actually cutting his tail off...

                        The ring doesn't work, I wasn't touching him but still he kept spinning like a spin top. He stops when casting but not long enough to cut his tail before he spins again. So f****ing frustrating.

                          How does Seath navigate his own archives if he can't fit through most of the doors? Also... Seriously... What's with the tentacles? Does being born without scales include also having octupus legs?

                            Inaccuracies here - First off, Seath didn’t build the Archives. The archives were given to him as part of his Dukedom reward for his participation in the Great War. Second, he didn’t go mad as in his obsessions made him insane. More accurately he’s a mad genius in the sense he disregards all morality and empathy, this is where he is seen as insane for he’s experiments and abductions are seen as abhorrent. Third, he plundered the primordial crystal during the war so he could study it, he didn’t discover it for it was already part of his reasons for betraying his own. This is how he discovers soul crystal sorceries for he learns there’s a close relationship and/or link between crystals and soul, it might even be a reason for the undead curse. Anyway, I don’t see Seath as a bad guy, I actually feel sorry for him in a sense and admire (in a game lore perspective) how he transcended his own weakness through arcane science. Granted the cost was very high, but achieved what he was after...until an undead jerk went full Havel on his crystal and him. :P
