Once you’ve defeated the Butterfly of Delirium boss in the Ruined City Center you’ll be asked with finding the Goddess Statue to progress in the story. Depending on how much exploration you’ve done, you may have encountered the Goddess Statue already, but if you haven’t this guide will explain exactly where you need to go.
Head to the Park Ruins Fast Travel Point
The Goddess Statue is actually located very close to one of the fast travel points in the Ruined City Center location. Assuming that you’ve activated the Mistle just before the boss fight with the Butterfly of Delirium, you will have access to the right fast travel point to get to the Goddess Statue.
From the teleport menu select the Ruined City Center and then select the Park Ruins (You can also use the Poisonous Butterfly Nest as well, but Park Ruins is closer). Spawning at the Park Ruins you will see that there is a ladder in front of you on the ledge to the right. Slide down the ladder and proceed forward and you will find that the Goddess Statue is sitting at the bottom of this area.
Walk up to the Goddess Statue and interact with it to lower a ladder which will lead you to a new area.
