Chaos Witch Quelaag

Chaos Witch Quelaag is a boss in Dark Souls.

Description
Queelag 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.

Lore
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 body 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.

Strategy
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.

Location
Found in Quelaag's Domain in between Blighttown and Demon Ruins.

Triple Fury Slash
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.



Chaos Stab
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.



Lava Surge
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

Leg Stomp
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.



Fire Burst
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.



Lava Spew
Quelaag will emit fire jets from her spider body.



Removed content
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.
