Return to cathedral ward and go down to the side of the large staircase where you fought Amelia. You will find a path that will lead you to a huge graveyard. Here you will find Rabid Dogs and a lot of Afflicted Yharnam Riflemen. Moving further into the graveyard brings you to a graveyard where a mine where Wicked Hags are patrolling.
As you go up the stairs you will be greeted by more Wicked Hags, Rabid Dogs, and an Eldritch-like Witch
As you continue on exploring , you will find a gate that is locked. Take the pathway down on the right instead. There you will find a lift that will transport you back to the entrance of Hemwick. On the opposite side, you will find a barn with horse cadavers around. As you go deeper into the barn, you will find a ladder. Climb this ladder and then descend the stairs. In the other room, you will find an old man in a wheelchair trying to attack you.There will be stairs in the room where you will pick up an eyeball. After battling the Eldritch Witch, you will find a roof as you move further into the room.
By the roof there is a path leading to another graveyard garden where Ogres and Hags are waiting. Here you will find a path which can open the gate that was locked earlier. At the end of this path, you will also find a corpse that will give you the Lake rune.
Fronting the gate is a hill-like path where a house sits on the side. There will be a chest beside the house too. You will find a path filled with corpses lined along the way and where a building with an arch is located.
Take the stairs down which will bring you to an abandoned church lobby where you will battle the Witches of Hemwick--which summon several Eldritch Witches. The Witch of Hemwick is an old hunchback hag that appears and disappears. There will be a red orb before the witch appears so keep your eyes peeled and prepare your charged attack. Once you kill the Witch of Hemwick you will be awarded with a Bloodshot Eye. Here you may also activate the lantern here.
At the end of the room, there is a room also in the church where a dead hunter rests. Inspecting this will give you a Rune Workshop Tool.
Note: Talking to Gehrman at this point, will open a door a the cathedral ward, which will bring you to a courtyard. A chest will be available which will give you Communion. At the side, there will be a bridgeway leading to another tower (Healing Church Workshop).
