Quelaag is a daughter of the Witch of Izalith and, along with most of her family, failed to escape from the chaotic flame and was corrupted by it. Due to exposure to the flame, Quelaag and her sister mutated into spider-like creatures with their upper body being fused to the monsters' backs.
She is the Fair Lady's older sister. When their mother, the Witch of Izalith along with their other two sisters became the Bed of Chaos, she fled with her sister. Although their sanity is intact, their lower bodies became bound with demon spiders. When her sister became weakened and blind, Quelaag remained in Blighttown to protect her from anyone or anything that would try to harm her.
A relatively easy way to beat this boss is to be human and summon Maneater Mildred, whose summon sign is right outside the Fog Door. Let Mildred distract Quelaag and stay away from her lava attack, as this is certain death. When away from her, pick off her health with ranged attacks, while Mildred tanks. This way Quelaag should be dead within a short period of time.
Another easy way to kill her is to get any halberd with a vertical light attack, such as the Great Scythe or Gargoyle's Halberd, and then repeatedly hitting Quelaag's human part. When aimed properly, she will stagger every time the attack connects, interupting whatever she's doing. This can be repeated to prevent her from attacking at all.
There is a spot between the stairs on the far side of the arena and the wall where Quelaag is unable to reach the player, at which point she can safely be killed from a distance using ranged attacks.
- Hitting her human body will stun her instantly.
- The Black Knight weapons will do extra damage against Quelaag.
- It is possible to summon Maneater Mildred for this battle provided she was defeated in Blighttown. Mildred has a large amount of health and can help distract the boss whilst the player attacks from a distance or heals.
- Running on the right-hand side of the swamp to Quelaag's domain will let the player ignore all enemies with ease, which can speed up the process of retrying the bossfight.
- Very rarely, Quelaag will actually jump at the player from a considerable distance. If this connects, it will knock the player down regardless of their poise, and inflict massive damage.
- Further, she can follow up with a lava attack, resulting in an almost guaranteed death to an already injured player.
Triple Fury Slash[note 1]
Quelaag will charge up briefly and swing her sword from bottom-left to top-right (from her perspective). Roll to the left (player's perspective) to dodge this attack easily.
Quelaag will charge up for a longer time and stab with the sword, holding it out for a short duration. This attack homes in much more reliably than the slash and deals multiple hits.
Quelaag can create lava pools in three ways:
- She may briefly fire globules that form small lava pools;
- She may stop to generate large amounts of lava in front of her over an extended duration, during which she is completely vulnerable to attacks;
- From a range, she may leap abruptly towards the player, firing lava
Quelaag will lift four of her legs and slam them back down. This attack can be performed from the left or right side, or directly in front of her. It has a very long startup and is easily dodged.
Quelaag hugs her spider body and, after a roar, performs a deadly explosion. Quelaag will use this attack if the player gets very close to her body, such as beneath her legs.
Quelaag will emit fire jets from her spider body.

Soul of Quelaag
Quelaag had dialogue removed from the final game:
- Go back. Forbidden be, these parts. The realm of the creatures of chaos. They accept their banished fate. Go back. Lest the flames devour all, and the children of chaos feed upon your charred ashes. Those who defy the pact... Those who trespass Quelaag's domain... May you feel the depth of our wrath! Ahh, a precious new sacrifice! Forbidden be, these parts. The realm of the creatures of chaos. Go on, go on ahead... Welcome, bringer of meat. The children of chaos are hungry; give yourself to Quelaag's flame!
- This indicates that Quelaag had a matriarchal status within the Chaos Servant covenant, along with or instead of her sister.
- According to Miyazaki, Quelaag's name is pronounced "kwee-leg."
- According to an interview with Miyazaki, Quelaag was inspired by the Cragspider, a unit from the fantasy board game Dragon Pass. Dragon Pass received a Japanese release by Hobby Japan.
- Another possible inspiration is Lolth the Spider-Queen, a half-spider demon goddess in Dungeons & Dragons canon. She is first encountered in the 1978 adventure module Vault of the Drow. Like Quelaag, Lolth rules over a subterranean domain.
- Damage is listed per hit.
