The Last Faith

When you first meet her sitting outside the Oxnevylle Manor she will ask you to help her find an item. She needs the Blessed Teacup which is found in The Esk Mansion. You will be searching pretty much every room so you will come across these pretty easily. You find the Teacup using the third mirror it will bring you out on the right side of the mansion in front of three Dream Catcher Pastilles. Just return the teacup to Helenya and you will get this achievement.
