Strategy 1 (Melee)

This is a relatively straightforward fight. You're going to sprint from enemy to enemy killing the ones with the red aura as fast as you can, following it from one enemy to the next. The undead do very low damage so prioritize offense and heal if you take too much damage.

In phase 2 there will be one enemy that possesses the red aura for the duration of the fight. He will be closely guarded by other undead who will try to put a protective barrier between you and them. Try and maneuver around them if you can, or if you feel confident try and AoE them down with a wide swinging weapon. Rolling into enemies is a good way to get out of trouble, as it will make them stumble backwards which should give you some breathing room.

Casters will pool their magic together with the main hollow to fire a black mass that goes through objects to hit you but won't track. Keep these four casters alive until they start pooling their magic separately making a curse debuff fog. Kill one and their spell will be halted. Ignore them and the player will be instantly killed by a curse.

Pontiff's Left Eye will allow you to dive into the mob safely when you use a weapon with large horizontal attacks as it will heal you for each enemy you hit in one swing. Using an item or consumable that increases stamina regeneration will allow you to remain within the mob longer, assuming a brief pause after each swing. As long as you are swinging with an appropriately sized weapon (such as the Hollowslayer), it is possible to heal at a rate faster than damage can be done to you, effectively rendering you immune to any attack that does not stagger. It is a good idea to avoid allowing enemies to circle in behind you, as it increases the likelihood that an enemy will be able to use a physical staggering attack on you before being knocked off balance by your weapon.

Strategy 2 (Magic)

Only a few magic spells are effective in this boss fight, namely (Crystal) Soul Spear, White Dragon Breath, Soul Stream and Soul Greatsword, which can all help you taking down deacons left and right. It may however be difficult to cast properly due to the high number of enemies and their ability to cast fireballs, which may interrupt your own spellcasting.
Note that despite the Soul Spear's ability to pierce through enemy groups, it can be very difficult to hit the actual boss with it due to not being able to target him properly; the same goes for White Dragon Breath and Soul Stream.
The seldom-used Pestilent Mist can actually be an absolute killer in this boss fight, in particular when used in combination with Aural Decoy or an Alluring Skull. Notice that it takes relatively long to set up such a trap, so it is advised to do so from behind a corner or pillar; also, try to cast The Pestilent Mist first, as its effect expires a little slower than the lure.

For the most part, the best strategy in this fight will be to slay a few deacons with a Soul Greatsword, then pull back behind the pillars on the sides of the battlefield, and start another attack on another deacon cluster.
In Phase 2 the Archdeacon and his henchmen appear, and once again the Soul Greatsword is your best tool to clear the way; however, the best way to attack the Archdeacon himself is with Farron Flashsword (or a regular weapon).
Generally speaking, standing around and casting is a bad idea in this battle, as you will get interrupted or overwhelmed quickly. Try instead to stay in motion, and use corners and columns to your advantage. Notice that Soul Greatsword will not bounce off obstacles and can therefore also be used to attack from behind a pillar.

Strategy 3 (Caster/Pyromancy)

With Pyromancy this fight becomes a walk in the park and you don't even have to be a dedicated Pyromancer, I used this strategy with my Sorcerer and only swapped the equipment and spells to Pyro without respecing my attributes. Use Great Chaos Fire Orb for damage and Flash Sweat to buff yourself. This does several things for you: GCFO does a lot of AoE damage which means you don't have to always target the red glowing guy, it's enough to get one that is near him. It kills a lot of other Deacons too which breaks up the cluster so you can easily focus on the main target. Flash Sweat lets you pretty much ignore their fireballs even at VIG20 on NG+.

If you need to run to the other side of the cluster, run behind the pillars to lessen the damage you receive even further. When the boss is down to 50%, run up to the Blue Deacons and kill them as quickly as possible or they will heal the boss. Use the corners of the building in the middle to heal yourself and pull the Cluster around the corner and away from the main boss, leaving him open on the other side. See video above as an example of this strategy, although it was made on NG+ you can apply the same tactics to NG.




First Phase (Red Orb moves from Deacon to Deacon)
Lunge A Deacon will lunge at you with the Cleric's Candlestick for weak damage.
Fireball Some of the Deacons throw fireballs at you.
Second Phase (the Archdeacon Royce appears and get surrounded)
Curse  The Archdeacon Vanguard will congregate and cast a long build up spell that will cover the arena in curse-inflicting fog. Can be interrupted.
Deep Soul Fires dark soul dregs. These souls are drawn towards life, so they will follow you or nearby summons.


Lore Theories

The deacons use pyromancy in addition to the miracles typical of clerics.

Pyromancy is considered heretical in Dark Souls so this shift to pyromancy is probably connected to their fall from grace.

The red aura that hops from deacon to deacon has appeared before in Bloodborne.

This red aura is connected to blood-drunkness, buffs granted by witches, "rot" and Vermin.

Mad Ghru can also obtain a red aura after grabbing you.

The deacons were followers of Aldrich, Devourer of Gods that stayed behind to protect his tomb.

The name of the Archdeacon in this fight is Royce, as indicated by the description of the set found on his corpse after reloading the boss arena.


Notes & Trivia

  • Pontiff's Left Eye Ring is very useful in this fight, due to the clusters of enemies making for good multi-hit opportunities. Spells such as Poison Mist/Poison Spores can also serve as decent crowd-control, simultaneously wiping out a large number of deacons when used properly.
  • Bring a Dagger or Mail Breaker to this fight, as it is very easy to fish for backstabs, assuming your target isn't tightly clustered with the other deacons.
  • Royce is in the boss fight arena for the whole time - during 1st phase, he is inside the coffin. 
  • The Farron Greatsword is particularly useful here, due to its special moveset.
  • If you want to make this fight even easier try to use the Ring of the Evil Eye and if you need FP regen try the Executioner's Greatsword. In NG+, the +1 version of the Ring of the Evil Eye is found right behind the large altar in the area just before the Deacons boss fight.
  • As of App Ver 1.05 Regulation 108, this boss is optional, due to a glitch allowing you to bypass the barrier in Irithyll of the Boreal Valley that requires the Small Doll to go through.

      Died to these guys on NG++ with my lvl60+6 pyro. It's like the crystal sage, those projectiles end up being pretty damn dangerous with the damage boost.

          While trying out a parry run I saw that this line on combat information is wrong:
          Can be parried, which allows to perform a riposte, backstabbed or pinned down. *note* The possessed deacon can't be parried since it doesn't attack the player.

          The posessed demon does in fact attack the player, but it is very rare. The Archdeacon for comparison has a much higher attack rate/chance.

            Hey i've noticed that in weakness, there is Vow of Silence. I think that you might want to point out that vow of silence doesn't stop them from cursing you.

              Only realized this boss had a curse attack from Jerma’s old DS3 stream. The fight has to go on pretty long whilst being too passive against the important targets for it to happen.

                Omg the set didn't even say that Archdeacon name is Royce. Where you get that from? Also where the idea of him being in the coffin came from? It's not mentioned anywhere. It's clearly shown he spawned in with his 4 blue guards from the ground, not spawn walk out of the coffin. Please don't anyhow speculate.

                  Possibly my favourite boss in the game, I'm not keen on the Cathedral as an area so these were the perfect ending, it's almost like a stress reliever being able to wail on so many enemies without much reply and it's something you won't get many other times throughout the series.

                    Alright... I've killed this boss a few times but I still don't really understand how to stop the curse build up attack that covers the whole arena.

                    Who exactly am I supposed to be interrupting? Do I need to kill ALL of the dudes channeling dark, or do I just hit the main red guy? Or both? I killed at least 1 or 2 of the dark guys during the cast, but the attack didn't stop. I also hit the main guy several times and that didn't seem to do it.

                    I'm on them now at SL20 with a +3 weapon, trying to stay there (long story, but no I'm not invading), so not understanding this attack is a bit more of a problem this time around.

                    When I figure it out I'll post back here, but if someone already knows the answer it'll save some tedium.
