The Asylum Demon (不死院のデーモン) is a boss in Dark Souls, located in the Northern Undead Asylum. It is the first boss in the game to be encountered by the player.


The Asylum Demon is found in the Northern Undead Asylum. It will attack the player in the exit room that lies immediately after the first bonfire, through the first set of large double-doors. It can be first seen standing above the room before it jumps down to attack the player.


The Asylum Demon wields a Demon's Great Hammer, an intimidating weapon molded from stone archtrees. The demon has an almost draconic appearance, with spotted blue-green scales all over its body and a pair of stubby wings on its back. It sports a tail and horn-like growths portrude from its legs and arms. Dark red eyes are accompanied by a set of large teeth that are revealed by the demon's permanently exposed gums.


The Asylum Demon is a greater demon spawned from the Bed of Chaos, the entity that appeared following the attempt of the Witch of Izalith to make a power similar to the First Flame using her Lord Soul. The attempt was successful and she create the Flame of Chaos but Izalith and her powerful soul became a seedbed for a new lifeform: the mother and source of all demons[1][2][3]. After its birth, the Asylum Demon managed to survive the war that the Silver Knights of Gwyn, Lord of Sunlight waged against its kind[4] and at some point it was able to escape from the ruins of Lost Izalith, bringing its Demon's Great Hammer, made from the stone archtrees, with it[5]. The demon wandered Lordran until it came to reside in the Northern Undead Asylum, the prison designed to keep Undead locked away from the rest of the world until the end of time[6][7], and that became its domain.


The first encounter with the Asylum Demon is optional and it is highly advised for first-time players to escape the room to avoid confrontation. However, if the player has obtained Black Firebombs as a starting gift, they can be used to defeat the demon relatively quickly, requiring just 5 of them (in NG). Killing the Asylum Demon within this first encounter will yield the Demon's Great Hammer.

Should the player avoid the first encounter, they will have to endure the mandatory second encounter with the Asylum Demon. However, the player can gain a massive advantage by using a plunging attack from the ledge above the boss. This will typically deal 1/4 of its health bar, varying depending on which weapon is used. Take note that wielding one's weapon two-handed is recommended for the plunging attack, as it will increase the damage of the attack. Furthermore, players should not stand upon the platform for too long because the demon will eventually leap up and destroy the platform, potentially killing the player.

On New Game Plus, the Asylum Demon can be easily defeated in the first encounter as the player retains all of their equipment from their previous playthrough.


  • Players can escape from the Asylum Demon's fight on the first encounter, by going through the doorway on the left-hand side of the room, just as one can do so for the initial fight with Seath the Scaleless. However, on the second encounter, it is impossible to do so.

  • The Asylum Demon shares its battle soundtrack with Taurus Demon and Demon Firesage.
  • The Asylum Demon is a callback to the Vanguard tutorial boss from Demon's Souls, as it displays nearly identical behavior.
