If you kill Quelaag and ring her bell or collect the two firekeeper souls before killing the Gargoyles, in addition to not be in his jail anymore, he will kill the firekeeper Anastacia without being a friendly NPC located at firelink shrine.

Who killed the firekeeper ds1?

Anastacia of Astora, also known as the Ash Maiden, is the fire keeper of Firelink Shrine. She will upgrade your Estus Flask if you bring her a Fire Keeper Soul. She is unable to talk until you bring her back to life, after she is killed by Lautrec.

Should I kill Lautrec immediately?

He won't drop his armour, but will drop 5 Humanity, 1000 souls and Ring of Favor and Protection, a very powerful ring that is useful the entire game. ... Killing him early will end this sidequest, and you will miss your chance to obtain both his and Anastacia's armor sets.
