Another PvP/PvE cosplay build...
Mildred is a cannibal Butcher who invades you in Blighttown. After you kill her Black Phantom form, you'll be able to summon her as a phantom to help fight Chaos Witch Quelaag. As an invading Dark Spirit. Her invasion can be triggered by walking out to the right from the second bonfire in the poison swamp. Be wary of moving into the poison and of mosquitoes moving in to attack.
Please Enjoy
