Full Cathedral of the Deep Walkthrough
Finding Paladin's Ashes and Crest Shield
From the first Bonfire, to the left you can follow the path down to take on a dagger-wielding enemy and behind it, Paladin's Ashes (this enemy will sneak up behind you while you fight the axe-wielding enemy at the top of the stairs if you do not kill him first.) Head up the staircase to take on an axe-wielding NPC who also tosses throwing knives at you. He'll drop the Spider Shield. If you head to the left of the stairs into the wooded area, you can find a corpse with a Titanite Shard 1x. To the right of the stairs, follow a path a drop down to the lower path. Follow the path up to find a Crest Shield.
Continue up the stairs through the archway and into the wooded area. You will encounter undead dogs and hollows perched on the stone walls firing flaming bolts at you. This can be a chaotic area trying to fight off the dogs and dodge the bolts, so use the environment to your advantage by using the trees to block bolts while engaging the dogs. Once you have cleared the enemies, you are safe to grab the Large Soul of an Unknown Traveler that sits on a ledge to the right of this area.
Proceed forward into the next area where a self-immolating hollow will charge you, you will encounter many of these enemies in the Cathedral. The best way to fight them is to charge at them and kill them before they have a chance to transform. Enter the cathedral ahead and open the double doors to find and light a Bonfire in front of an altar. In the corner of the cathedral is a corpse with the Notched Whip. If you have bought the Ashes of Arandiel DLC, there will be a man or a piece of a paint nearby the altar. Interact with them to start the DLC content. It's worth noting that Siegward's quest can be furthered here, he's in the well nearby the entrance. He appears once you have opened the double door that from the Cathedral lead to the graveyard.
Exit the church and head right, where you find a group of hollows in prayer around a corpse. Dispatch them to loot the Estus Shard 1x from the corpse. Continue up the crumbling stone stairs and enter through the open gate. On the path ahead will be many zombie-like, Reanimated Corpses. Continue forward until you come to a path on your left. Take that path, with more zombies, and on your left, you can take another path where a zombie is crouched in front of a gravestone. You can loot a corpse here for an Astora Greatsword. If you continue to explore the network of paths in this graveyard you can find a Fading Soul 1x and Executioner's Greatsword. Looting this will trigger a zombie ambush. If you head up the path on the hill right to the right of the gravestone with the sword you will come to a ledge where you can drop down to a path where a solitary hollow lurks. Head up this path and cross stone walkway/bridge.
Dispatch the several zombie hollows here and cross the bridge and head up the stairs. If you have befriended the giant archer in Undead Settlement, he will shoot arrows in this area, only targeting enemies. If you have not made friends, you will continue to be a target for his arrows. Along the stairs you will encounter a dual wielding grave warden. Dispatch the enemy and at the center, make a right down a flight of stairs to come to an area marked by many spears stuck in the ground. There are several items to loot from corpses here, including Young White Branch 1x, Large Soul of an Unknown Traveler 2x, Repair Powder 2x, Undead Bone Shard 1x.
Return up the stairs and head right and right again down a short staircase to find another staircase leading up into a chamber. Inside the chamber you can loot a corpse for a Curse Ward Greatshield. If you travel down the stairs here you will come to a ladder, which you can kick down and descend. At the bottom, you can exit to the outside and if you go straight you will come to an area patrolled by a zombie hollow. Near here you can approach a structure with several small windows, one of which is open. Loot a Titanite Shard 1x from the corpse in the open window. Entering this window leads back to the bonfire. Instead, if you descend down and to the right from here you will come to an area with both a large and normal Crystal Lizard. Up a narrow hill here you can find a tree with a corpse that holds a Titanite Shard 1x
Back in the area with the Crystal Lizards, in the corner you will a narrow passageway from which you can enter into a dark room where you will find a writhing rotten flesh. In this room, you can loot a corpse for the Poisonbite Ring. If you exit this area near the building, you will find another Crystal Lizard and a corpse along the wall with a Titanite Shard 1x. Head down the stairs to encounter another writhing rotten flesh. To the left another writhing rotten flesh waits in the water. On a small mound, by a tree stump to the left you will find a Saint-tree Bellvine. Ahead will be writhing rotten flesh in the water.
Continue down the watery path until you come to a hill on the left. Go up and left into the building and climb the tall ladder you kicked down earlier. Exit the building and proceed ahead up the central staircase. Around the corner to left, you can find Rusted Coin x2 behind some boxes. To the right you can loot a Red Bug Pellet from a corpse. Beyond you will encounter several hollows, one with a spear and shield, one self-igniting rushing hollow and one above firing arrows at you. If you head down you can cross some broken pathways to a roof across with a hollow self-igniter. On a balcony here, you will find a hollow and a corpse with a Soul of an Unknown Traveler. When you approach this corpse, hollows will crawl over the balcony and attack.
Proceed down a narrow stretch of the roof and to the landing where 3 archer hollows and a spear and shield hollow lie in wait. After dispatching them, make the short, easy jump to the slanted rooftop opposite the one you came down. This leads back to the rooftop where two more gremlin hollows are ready to drop down in ambush. From here you can drop down onto a flat rooftop just below where you will find 3 gremlins ready to ambush you if you had taken the normal path instead. To the far right side of this rooftop you can see a gremlin hanging on the slanted rooftop ready to ambush you if you grab the item below. Take a swing at it from the rooftop if you can or just drop down and take care of it to loot your Red Bug Pellet. Head down this path until you come to several hollows in worship by a large Evangelist. You can loot a corpse here for an Undead Hunter Charm 3x.
Head back down to the landing and make a left to go down the walkway. Draw out the hollow wielding a Halberd and fight him alone, 1 gremlin hollow will leap out from the doorway to your left (and 2 from the rooftop if you didn't dispatch of them earlier). If you head into that room, you will see more of the gremlins on the ceiling waiting to drop down and attack. You can loot a corpse here for a Soul of a Nameless Soldier 1x. Exit this room and head left to see 3 hollows resting. If attacked from a distance they will throw Undead Hunter Charms at you before attacking. Head up the next staircase into a room where 2 dual wielding grave wardens lurk. If you head up the staircase here, you will encounter 2 of the self-igniting hollows. At the top of your stairs, proceed and to your left will be a seated hollow. At the end of this path you will find several hollows kneeling. A corpse will have an Ember 1x. An axe-wielding hollow will jump out at you here from the left.
Beyond is a large double door that you can open and enter. Down a short flight of stairs, you will see a tunnelway on the left. There is a tar blob down this tunnel. Down the hallway will be a corpse with a Duel Charm 1x. In the next room, 3 undead will attack you.
Proceed to the next area, where you can either make a left to a lift or right into a doorway. If you take the lift on the left down and proceed down the hallway you will come to a grated door which you can open and exit to the exterior, leading to double doors into the building that you can open to unlock the shortcut to the Bonfire.
Getting Past the Giants
Make your way back up the lift and enter the doorway. Down a long staircase you will come to a room with an Evangelist. On a balcony outside the room is a corpse with a Deep Gem. Return up the stairs to defeat a tar enemy and step outside to enter a central chamber with a massive giant who attacks you. Note that these giants can be killed and are guaranteed to drop a Large Titanite Shard, but you might miss it permanently if you don't pick it up before either dying or reloading the area. You shouldn't fight him here; instead, wait until you go down to the bottom of the large room where it is easier to kill him. You can dodge his attacks (or return to the top of the stairs and stand in the center of the dais until he starts to attack, then retreat a moment and take swipes at his hands). Navigate the perimeter of the area, being mindful of enemies here. Along the way you can loot corpses for a Soul of a Nameless Soldier 1x, and Lloyd's Sword Ring. The giant can easily kill you in one hit so be aware of his positioning at all times. On a corpse hanging over the edge you will find Exploding Bolt 6x.
Continue dodging the giant's swipes until you arrive at a doorway to a staircase heading down. Upon arriving at the first landing, make a left and head into the next room where several gremlin hollows emerge to attack. In a corner a corpse lies with Seek Guidance but beware of the tar blob that will drop when you approach. Exit via the ladder in the corner and ascend to a room where an Evangelist patrols to the left. In this area is a corpse with an Ember 1x.
Return back to the staircase leading down to come to a room with a chest in front of an altar, except in this case it is a mimic. Defeating it or using an undead hunter charm will cause it to drop a Deep Braille Divine Tome. Take the next staircase down and enter a room to face off against a greatshield and mace-wielding Cathedral Knight.
Note: Giving the tome to Irina of Carim and buying the dark spells will fail her questline.
The Deep-Accursed Room
In the adjacent room, upon walking in a spider-like Deep Accursed will drop down to attack. To make this fight easier, run back to the entrance of this room and attack it from the doorway. Defeating it will earn Aldrich's Sapphire. In this room you can loot an Ember 1x. Exit this room back from where you came and enter the next doorway to enter the large open area where the giant is. If you are in Ember Form, Longfinger Kirk (one of the Fingers of Rosaria) will invade when you enter the room. Be careful as he can hit hard. Once taken care of, he'll reward you with a Spiked Shield and Barbed Straight Sword.
In front of you will be a lever, if pulled it will raise a divider. Nearby there is a cathedral knight and some gremlins, with poison water spewing fountains along these walkways. You can loot a corpse in a corner here for a Soul of an Unknown Traveler. Continue down the stairs, open a grated door and continue until you reach a double door. Open it and you will find a lift. Don't take the lift and continue to another double door, which opens a shortcut to the Bonfire.
Go back in the room with the giants. The one in the corner on your left (the one that has not attacked you) will be surrounded by tans and several corpses that can be looted for Drang Shoes, Large Titanite Shard 1x and Dung Pie 4x, Large Soul of an Unknown Traveler 1x, Pale Tongue 1x, and Drang Armor and Drang Gauntlets. Behind a pillar you will also find the Drang Hammers.
Nearby the other giant you can loot the Maiden Set from a corpse here as well as a Soul of a Nameless Soldier. Make your way carefully to the large double doors here and open them to reveal a large staircase down. At the bottom of the stairs is another set of double doors which you can open to exit to the outside. Directly ahead on a corpse along the railing you will find Saint Bident. To the right at the end of a broken staircase you will find Homeward Bone 2x.
Ensuring the Meeting with Patches
It's worth noting that taking the path along the rafters will prevent Unbreakable Patches from making an appearance later in the cathedral (See Rosaria's Section). To meet patches surpass the giant in the corner, and climb the stairs on the left. This leads to a chapel-like area where you will see a cathedral knight and several cleric hollows. If you head left to the edge of this area, you will find a corpse with an Ember 1x. There is also a cathedral knight seated in one of the pews here. Take a lift in the opposite direction of the stairs you have taken and you'll reach a double door. Open it to open a shortcut to the graveyard and trigger his spawn, then reload the area and come back. Continue your path along the stairs, and you'll be in a room with a corpse with a Duel Charm 3x and Siegward of Catarina. Siegward will talk about a treasure and tell you to walk over the narrow bridge. Walk the bridge and in the middle, a cutscene will trigger.
Finding the Rosaria's Fingers Covenant
Now return to the lift beyond the double door nearby the last shortcut you opened to the bonfire and take it up to encounter a crossbow-wielding enemy. Step outside and take the narrow ledge on the left around the corner to find a ladder. Take the ladder up to take out a red-eyed foe and take the wood plank ramp out to obtain the Deep Ring. You can drop down to the narrow roof here and take it up where a thrall will emerge to attack you. Follow this path to the left and at the end you will encounter an axe-wielding enemy on the right. Make your way back in the opposite direction to encounter a halberd-wielding enemy. If you take one of these narrow rooftops down to the tower at the end, you will find a corpse with Arbalest on it. Return to the main path and at the end, you will find a thrall enemy in front of a corpse with a Pale Tongue 1x. Another thrall will climb the wall and attack you here.
In the middle of this wide ledge, take a doorway inside to come onto a series of curved rafters, where several thralls wait to attack. A cathedral knight is also present on a platform here (be careful, he can cast Emit Force). A corpse along the wall here can be looted for a Blessed Gem.
Make your way back across the rafters and on the right-hand side (opposite from where you came in) you will see a ledge that you can drop down to. The ledge is being guarded by two cathedral knights, the furthest one has a ranged weapon and the closer one will try to follow you down if not killed. It is a bit of a drop and will take some of your health, so make sure you're healed up before taking the plunge. From this platform you can drop down to another landing and ahead will encounter a casting worm where several more hollow worms will attack. They are weak to fire so pyromancy like Fire orb is helpful. There is a lever here you can pull.
Head up the stairs through the doorway to encounter several more worm enemies. At the end of this room, you can attack a seemingly unhostile enemy who drops the Red Sign Soapstone.
Through a broken portion of the gate here, open the double doors to enter a room with a Bonfire. In this room you'll find the Armor of Thorns Set on a body near the back if you have been invaded by Longfinger Kirk. Also in this room is a bedchamber at the end, where you will meet Rosaria, Mother of Rebirth the leader of the Rosaria's Fingers Covenant. This is the standard invasion covenant, as well as where you can find stat reallocation and appearance alteration services.
Note: Joining this covenant has implications for other NPCs and their Side Quests, so if you are attempting a specific playthrough please consult those pages to help with your decision making. For example, giving a Pale Tongue to Rosaria will fail Sirris of the Sunless Realms questline.
There's a lever outside Rosaria's Bedchamber, and Unbreakable Patches will be standing here if you have progressed things properly (a reload may be necessary). Activating it, raises the narrow bridge that leads to the graveyard.
Towards the Catacombs
Return to the area with the pews where you encountered the cathedral knight seated in a pew. There will be 2 deacons facing an altar you can dispatch. Beyond this central altar to the right of the archway you will find the summon signs of Horace the Hushed and Anri of Astora. Descend the stairs and enter the fog to take on the boss of this area, Deacons of the Deep. Defeat them to earn the Small Doll which allows passage to Irithyll of the Boreal Valley and Soul of the Deacons of the Deep. A Bonfire will appear. Resting at the Bonfire or coming back to this area will spawn in a drop for the Archdeacon set. Continue your journey either to Farron Keep or Catacombs of Carthus via the Road of Sacrifices or Irithyll of the Boreal Valley if you have already cleared Farron Keep and the Catacombs of Carthus.
