Maneater Mildred

Maneater Mildred is a character in Dark Souls. She is a (relatively speaking) heavyset woman wearing a Sack and wielding a Butcher's Knife.

Locations

 * Invades the player as a red phantom to the right of the second bonfire in Blighttown.
 * Appears as a white phantom if the player uses the summon sign in front of the fog door before the fight against Quelaag, if defeated as a red phantom.

Plot
Maneater Mildred has no dialogue whatsoever, and her appearances are brief. As such, little is known about her. She was probably included in the game to give offline players a taste of invasions and co-op play.

Given her garb, gender, and title, Mildred may be the entity that was seeking to devour Laurentius of the Great Swamp, but there is no concrete evidence to suggest this.

Strategy
Maneater Mildred moves quickly, but her attacks are slow, and don't do that much damage. She also can't block attacks very well and she can be stunlocked by any weapon. Mildred can be easily Backstabed or Parried, and takes high damage. On the other hand, fighting her can be dangerous as she spawns inside a poisonous swamp with movement impediments. It is recommended to lure her into the Bonfire area before engaging her.

Drops
Mildred drops her Butcher Knife upon defeat, as well as 3 Humanity.

Up to 8 liquid humanity can be taken from her using a Dark Hand.

Trivia
According to developer interviews, Maneater Mildred was created as a joke when one of the developers, inspired by the Meat Cleaver Black Phantom from Demon's Souls, invaded people in Blighttown with the Butcher's Knife during testing phases.
