"Awarded a Dukedom for his betrayal of the Everlasting Dragons, the albino dragon Seath the Scaleless has since become obsessed with his sorcerous experiments and research. Functionally immortal due to his possession of the Primordial Crystal, Seath uses his Channelers to seek out subjects for his nefarious procedures."
— Bio from Dark Souls: The Age of Fire

Seath the Scaleless is a boss in Dark Souls. He is one of the holders of a Bequeathed Lord Soul Shard necessary to satiate the Lordvessel.

He is a Dragon, but since he was born without scales[1] (hence his nickname) he envied the Everlasting Dragons and helped Gwyn by revealing him their only weakness: the Lightning. He was thus awarded a Dukedom. He then became a prominent scholar, amassing the countless library known as the Duke's Archives, and supposedly created Sorcery.


Encountered at the top of The Duke's Archives, and later at the end of the Crystal Cave.


The albino dragon, Seath the Scaleless, was born deformed and blind, lacking the stone scales that gave his kin their immortality. Seath became obsessed with gaining immortality, and when war broke out between the dragons and the newly empowered Lords, Seath betrayed his own people by aiding Gwyn, Lord of Sunlight, revealing to him that the dragons' greatest weakness was lightning.[2] He acquired the Primordial Crystal; a sacred treasure pillaged when he turned on the ancient dragons, granting him immortality."[3] Gwyn awarded Seath with dukedom for his role during the war and gave him a fragment of his own Lord Soul.[4]

During his time as duke, Seath became obsessed with his experiments and research, amassing countless tomes and was eventually driven completely mad.[5] The Channelers, sorcerers under Seath's command, traveled to far lands in order to acquire more specimens for Seath to experiment on.[6] These experiments resulted in many "mistakes", that Seath kept locked away in his dungeons.[5][7]

The six eyes of the Channelers compensated for Seath's blindness.[8] Crystal Soldiers populate the fortress, as well as a few Serpent Soldiers to help guard the prison.

Seath is said to be the creator of Sorcery[9] and is the object of the infamous sorcerer, Logan's, obsession. Seath's creations include the Pisaca, Moonlight Butterfly, and Crystal Ember.[5][10][11]

Seath found himself a target for the Chosen Undead, who required his shard of Gwyn's soul to access the First Flame. Seath set a trap for the Chosen Undead, and had his underlings capture them, but the Chosen Undead escaped, tracked him down to his lair, and killed him after destroying the ancient crystal that granted him immortality.

By the time of Dark Souls II, Seath had faded into legend, yet his legacy still loomed large. Like the other holders of great souls, Seath had been reborn in the countless ages that followed the repeated linking of the First Flame, and his soul continued to exert influence over the land. His role as the father of sorcery and the creator of the smithing techniques used by Weaponsmith Ornifex was considered legend.

By the time of Dark Souls III, Seath's legacy had been somewhat re-discovered. The Crystal Sages began to preach of the work of Logan, acknowledging the "Paledrake" as the being whom Logan learned from.[12] He became so revered by scholars that most assumed him and his influence on Logan to be a myth,[13] and he was worshiped like a god.[14]


When first encountered in The Duke's Archives, he regenerates health extremely quickly due to the power of Primordial Crystal, effectively making him invincible.. He inevitably kills the player[note 1]. Loss of souls and humanity can be avoided by wearing a Ring of Sacrifice, but if he kills the player through Curse, then a Rare Ring of Sacrifice is needed to avoid penalties. In addition, it is possible to travel back through the fog door to avoid being killed by Seath, however can still go through the fog wall after exiting. Regardless, the player must be killed by Seath in order to progress.

Upon encountering him again within the Crystal Cave, he will be fought within an arena that contains the Primordial Crystal. In order to defeat Seath, it is necessary to destroy the Primordial Crystal so that any damage dealt to him is not immediately healed. The crystal will respawn if the player dies or leaves the fight, making it necessary to destroy it in each attempt to defeat Seath.

Staying at his side makes it easier to stay out of the area-of-effect of his breath attacks, and he won't be able to hit with his claws or tail as easily. Video

It is also possible to use only a bow against Seath with great success. Get a good distance away from him and it is possible to get 4-5 shots in before he gets too close. The only real danger in this strategy is when running past Seath to gain some distance.

His only long range specific attack is the far curse beam. That means if players stay at a distance, one can lure him to fire the beam and charge his defenseless body.

Crystal curse explosion triggers when the player cannot be reached by any of Seath's other attacks; usually when situated behind Seath with the tails just out of reach. One strategy is to begin sprinting a good distance away from him once he arches forward to charge a ball of magic. A second approach would be to develop a high enough curse resistance and block some of the erupting crystals. Immediately heal the damage received before he executes his tail swipes/slams.

Being the godfather of Sorcery, Seath is extremely resistant to Magic damage, so it would be wise to try to use a different element when combating him.

When trying to obtain the Moonlight Greatsword it is best to attack the tip of the tail, as the area around midway through the tail is considered his body. Thus dealing damage to this area will not help in acquiring the Moonlight Greatsword.

A good strategy for acquiring it is when Seath himself breaks the Primordial Crystal. Wait behind the crystal until Seath starts to rear up his head for any of the Curse Beam attacks. Just before he fires it, start sprinting left or right around the sides and towards his tail. Seath will break the crystal and stun himself, giving the player ample opportunity to attack his tail three to four times. Make sure Seath's tail isn't clipping in the wall before trying.

It shoudl be noted that Seath takes extra damage if hit in his belly. As an example, when hit with standard 1H fast attack Man-serpent Greasword +15 in of his tentacles at STR 40, Seath takes 226 damage. And if hit in his belly by the same attack, he will take about 450 damage. If the character is tanky enough and has enough Curse resistance, he can stay right at Seath's belly and hit him without pausing until Seath dies, using his Estus Flask only one or two times.

Moonlight Greatsword[]

To cut off a tail it's necessary to deal a certain amount of damage against it. The HP of the tail increases with higher NG cycles and is based on the HP of the respective enemy. Seath's tail has 825 health on Ng and 1,295 on NG+.

  • Equipment load under 25% is highly recommended to cut his tail.
  • Lure Seath as close as possible to the crystal. It is ideal to kite Seath close to one of the walls, so that when he attacks with his breath, you have plenty of room to move around his other side. Once Seath is close enough to you he will pause and begin his breath attack; immediately run behind Seath. Run to his left side (your right), as he breathes his crystal breath from his right to his left. Seath will destroy the crystal with his own breath attack and be stunned temporarily. Without locking on to him, target the tip of his back (middle) tail and attack it while two-handing your highest damage weapon or using fast strong spells.
  • Use weapons that have vertical slash when two-handed: katanas, straightswords, greatswords, ultra greatswords, etc. Slash the tip once or twice, then run away. Provoke him to attack with his crystal breath, run to his tail, slash once or twice again, then repeat.
  • You can also use fast spells to cut his tail. Unlike using weapons, it is recommended to retreat from the boss battle (Homeward, Homeward Bone, or quit game) if you fail to cut it on the first try after breaking the crystal.

Boss information[]


Close Curse Beam[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
0 564 0 0 Strike No Both Medium

The first of Seath's Curse Beams: Seath will fire a beam from his mouth in a circular arc close to his body, and crystals will erupt from the ground around where the beam touched.


Breath Crystal[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
72 0 0 0 Strike
Curse: 2
No Both Medium

The crystals that erupts form the ground after each Curse Beam attack, they are unblockable and deal continuous damage, as well as curse build up.

Crystal Curse Explosion[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
144 480 0 0 Strike No Neither Medium

Seath's most dangerous attack: he will begin charging briefly, and will then erupt crystals from his body in all directions. This crystal eruption is even more damaging than the others and, of course, much harder to evade. The only way to avoid it is to get quite far away from Seath's body, out of range of the eruption.


Tail Thrash[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
612 0 0 0 Strike No Neither Medium

Seath will attack with his tails if the player stays near one of his three tails for too long. There are two variations of this attack, one where Seath repeatedly slams his tails onto the ground, and the other where he sweeps them. These can hit multiple times, stunlocking the player. This attack has considerable range, but it can be reduced by cutting off Seath's tail.


Far Cursebeam[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
0 570 0 0 Strike No Neither Medium

The same effect as the Close Curse Beam, except this is fired in a circular arc further away from Seath's body.


Straight Cursebeam[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
0 575 0 0 Strike No Neither Medium

The last of the different Curse Beam types, Seath fires a beam in a straight line from the base of his body to the end of the room, in the direction the player is standing.


Left or Right Hand Swipe[]

Dmg phy.png Dmg mag.png Dmg fire.png Dmg lght.png Attack Type Parryable Tracking Speed
624 0 0 0 Strike No Right Medium

Seath will swipe his left or right hand at the player. This is incredibly damaging and can only be blocked by high stability shields, but fairly easy to dodge since his hand hitbox is small.

Dark Souls OST - Seath the Scaleless


  • Respawning at the prison bonfire is tied to the room and not dying to Seath. This means being killed by Seath while outside the room will not move the player to the prison.
    • Similarly, if Big Hat Logan kills the player in this area they will be moved to the prison.
  • If the player cuts off Seath's tail it may not disappear and will persist after Seath has been killed.
  • The Japanese description of Seath's Bequeathed Lord Soul Shard uses the Chinese term "外戚 " which is used for blood relatives of the monarch's wife.
  • Seath's character is an homage to the dragon god of the same name in From Software's King's Field series for the original Playstation. The Souls series is often referred to as the spiritual successor to King's Field.
  • The ghostly hands that emerge from the tomes in the Grand Archives in Dark Souls III closely resemble those of Seath.
    • This is most likely a reference to the fact that Oceiros and the Scholars were researching on his sorceries.


  1. It is not known if Seath also was born blind (see Six-Eyed Helm of Channellers description: "Seath's lack of sight"; also, if one closes up on Seath's face, it can be seen that Seath has no eyes) or if he turned blind due to his experiments.
