Aldrich Faithful (item)

- Found in Irithyll of the Boreal Valley. Obtained by interacting with Archdeacon McDonnell's remains in the Water Reserve and accepting to join the Aldrich Faithful covenant. - From the Pontiff Sulyvahn bonfire, proceed through the level and make way to the opposite side of the big courtyard with several dead Giant Slaves. Enter the building at the end and hit the wall on the left to reveal a hidden ladder. Climb down and defeat the two Sulyvahn's Beasts lurking at the bottom. Once done, head to the far-left corner of the room to find McDonnell's remains.
