Old Demon King Information

Old Demon King is a boss enemy in Dark Souls 3. Burning in the pits of the smouldering lake, the corpses of demons surround him.

  • You can summon Knight Slayer Tsorig to help you fight this enemy. His summon sign becomes available by killing him after he invades. He will invade in the hallway before the collapsing rope bridge. Summon can be found next to the bonfire to the right of the fog gate.
  • You can summon a White Phantom Great Swamp Cuculus to help fight the boss. The sign can be found at the bottom of the stairs directly in front of the fog gate. If you summon her and defeat the boss with her surviving, the Spotted Whip and Cornyx's set will appear where you first rescued Cornyx of the Great Swamp.
  • This boss is optional.

 

Location

  • The Old Demon King can be found in Smouldering Lake, which can be accessed via collapsing the wooden bridge in the Catacombs of Carthus. The boss room is located to the left of the entrance, behind the Carthus Sandworm.

    • He will also try to raise his mace to attack but is unable to do so completely as it slams back down to the ground.

 

Strategies

Strategy 1 (Melee)

The first phase: The best opening is when he slowly vomits lava from your left to right. Just run next to his left leg (your right) and attack a few times before he is done. The next best opening is when he lowers his club to his left side and slowly swings it to his right side. Again move towards his left leg without target lock and dodge the swing behind him. Do not attack yet because he is about to continue with a AoE blast. Keep moving towards the tip of his tail and when you catch it you are far enough to avoid the AoE and take a few swings at the tail. A weapon with a lot of range and wide swipes is recommended.

Staying too long near him and especially in front of him triggers the fast AoE mouth blast. Attacking only a couple of times and then retreating to medium range to wait for openings is easier.

In the second phase: Now Old Demon King has a certain attack pattern: 1-2 melee attacks/combos and then a ranged attack. Usually no two ranged attacks in a row. Same openings as in the first phase work here too but triggering them is different. You can outrange every long range attack of this boss. As you return to medium range to catch his melee attack openings do not stop approaching. Keep moving towards him until he does a melee attack. If he lowers his club for the slow swipe do the same thing as in phase one. If it is any other melee attack you can dodge or even walk under him to get behind him.

Strategy 2 (Sorcerer)

One of the easiest bosses for Sorcerers. Just stay out or range and spam Great Heavy Soul Arrow until the boss is dead. Circle around the pile in the middle of the arena to take cover from his AoE attacks and keep moving.

Strategy 3 (Toxic)

Dodge his attacks until you get into range and cast Toxic Mist. Once the boss is poisoned, stay as far away as you can so he can't hit you with his spells. When the toxic wears off, get close and reapply it. Four rounds of toxic should do it.

The Storyteller's Staff's  weapon art is also very effective and a single cast will nearly defeat the boss by itself. One or two attacks will be enough for the poison to finish him off without having to reapply it.

 

Strategy 4 (Bow)

The Old Demon King can be easily defeated using a bow if you have a shield with good fire damage mitigation like the Dragon Crest Shield. Other than his fire spray attack, which you should block, there is nothing he can do to you if you keep your distance.

He moves slowly enough that it's possible to simply shoot him whenever he stops to perform an attack and continue to run away without him ever getting a chance to hit you; at some point in the fight, he'll start moving a bit faster, but it's still not fast enough to run you down.

It also helps to take advantage of one of the two mounds of corpses in the arena. Circle around one walking backwards, keeping your distance, and dodging the lava spew, lava AoE, and meteor attacks. Combined with the Cloranthy Ring, the Grass Crest Shield, and lots of careful rolling, this boss becomes almost trivial.

 

Strategy 5 (Pyromancy)

This fight will either be near impossible or very easy depending on how far you've advanced your pyromancies. The boss is extremely resistant to fire spells, so your best bet instead is to attack him with non-fire pyromancies. Boulder Heave will work, but your very best bet is getting access to Karla's Dark Pyromancies

Using Black Fire Orb will make this an easy fight. Stay at range and evade his melee attacks, which have relatively limited range. During Phase II, the only attack you have to worry about is his expanding fire circle. You can either move out of range, or roll through it at the right time to dodge the damage. Whenever he casts a spell, he leaves himself open to several Black Fire Orbs. When he summons the meteor shower, simply run until the meteors explode. Around 20% hp the boss will collapse and explode. As long as you outrange this explosion, the fight is essentially over, since the Old Demon King will simply lay there and not attack anymore. 

If you do not have access to Karla yet, another method would be using Black Serpent, although the hit rates are not that reliable, as it travels on the ground and the only hitbox it has to do with are the legs of the Old Demon King.

 

Strategy 6 (Pestilent Mercury)

For pyromancers which do not have access to Karla, pestilent mercury might be a good spell to use (30 int requirement). This works for sorcerers as well but would most likely not need it as they have their normal spells. You can cast pestilent mercury around a large pillar in the boss arena and run around it, letting the old demon king chase you, evading his attacks and damaging him at the same time.

Attacks

 

First Phase
Swing The demon will swing his hammer, causing fire and melee damage, beware AOE, move under the attack, toward the weapon, or get behind or below him.

Fire Ring

 

The demon will conjure a circle of fire that will move inwards or outwards from him, can be blocked or dodged through.

Fireball-

shower

The demon bashes his hammer in the ground and then starts to turn it in circles above his head.

Fire Glyph

The demon bashes his hammer in the ground, linear trails of fire covering different directions will emit from the center.  Take Evasive Action.

Meteor Rain

A phase two move, multiple slow flaming rocks will fall towards the player. Slight tracking. If you are quick, hit and run works. Evasive action and use of pillars to absorb shots is effective.

Lava Breath

The demon will spew lava at those in front of him. He will move his head to extend his AOE. His range is short and those flanking him or under him can smack him.

 

Lore Theories

  • The Old Demon King is the oldest and the last remaining witness of the chaos of Izalith. "The shriveled Old Demon King is now like a clump of burnt ash, but he is the last living witness of the Chaos of Izalith." - Soul of the Old Demon King.
  • "This weapon has survived since old Izalith, and is imbued with remnants of the Chaos Flame." - Old King's Great Hammer.

Trivia

  • If, when entered the arena, you go straight forward and then, look carefully up on the left side on top of the pile of dead demons that are surrounding the whole area, f.e. Centipede Demon body, a boss from Dark Souls.
  • During the second phase of the fight, if the player listens carefully to the song playing, they can hear a small slightly remixed excerpt of the Bed Of Chaos's theme.

      First boss I killed on first try without any help. Used a +6(or maybe 5?) Dark Sword two handed, and all 10 Estus +6. Just roll under his hammer and hack away at his legs and tail. It should be pretty easy to get behind him. Every now and then you have to eat his AoE attacks but that's why you use the Estus.

      Almost died right at the very end when he exploded. Then he took a knee and basically waited for me to finish him off. Kinda sad actually... never seen a boss admit their defeat like this before.

        Did they buff him? I just killed Wolnir in less than 1 1/2 minute and went to him. He just crushed me for the 7 attempts. Also, the mobs inside the Smouldering Lake seems to be a lot stronger since the first time I played DS3 (about a year ago).

        • 30 May 2017 18:29  

          well, he is quite easy to defeat, i did it with my first attempt. Just took both Tsorg and Cornyx, and used a black knight sword in his first phase, and a bow with poison arrows in the second.

          • 21 May 2017 11:02  

            Somehow you can sometimes glitch into his hammer and remain inside it for a while while he moves it with you inside around until he does something with aoe damage and knocks you out of it.

              I believe the NG+9 souls are incorrect as currently stated in this article (now it says 71,790). I got 95625 solo at NG+7, which should be equal to the NG+9 amount.

                There's a sad moment where after the demon king uses his explosion ability where he's too exhausted to continue fighting. It's sad, even though it's a demon, to see the old king at that state surrounded by the charred corpses of it's brethren. ;(

                • 06 May 2017 00:48  

                  With the latest DLC, mages can use Great Soul Dregs and Pestilent Mercury to easily cheese this boss. Just keep your distance, buff your catalyst and attack.

                  • 05 May 2017 00:23  

                    He is a slow boss. Even if one attack gets you, you should be able to avoid the second one. Only the final attack is a problem. But seriously, if you go with a 7 weapon it will most likely die before he has a chance to do it.

                    • 04 May 2017 12:38  

                      Pestilent Mercury is amazing against this boss. Summon Great Swamp Cuculus for this bossfight, and let her engage him. While they're fighting, keep on casting Pestilent Mercury by the boss, since he doesn't stray too far when he's engaged with her.

                      • 03 May 2017 01:34  

                        Fire Ring attack appears to glitch and 1-shot player and all summons regardless of how low the damage registers (sub 200 with stacked fire resistance or 275 on Swamp Pyromancer, Black Knight, etc.). Just had it score a triple on us three full hp. Did not do this prior attempts on the boss that I had to Homeward out trying to get Pyromancer items.

                        • 01 May 2017 10:17  

                          how the ***** are you supposed to roll through his fire rings?

                          i swear I've initiated my rolls on the very precipice of the ring's inside but by the time I arrive on the other side my ankles must get tickled by the slight heated breeze of the ring of fire and I get hit

                          • 16 Apr 2017 02:07  

                            He's the last witness to the chaos of Izalith. I have him waiting for me to finish him, and thought about sparing him..... But, alas, he awaits the cold embrace of death, what cruel fate to deny him the end he deserves.... Goodbye Demon.

                            • 12 Mar 2017 03:19  

                              Easy as hell with any ranged weapon or spells (besides pyro)

                              Melee? ***** you. AOE left right and center, unavoidable and unrollable through ground fire. Meteor spam you can't see. Timing that vary and aren't consistent. Good *****ing luck getting this guy as melee, doesn't matter what gear you have. Bring a friend if you want to survive more than 2 hits.
