Demon Information

Demon is a mini-boss enemy in Dark Souls 3. It is found roaming the Undead Settlement and Catacombs of Carthus.

  • The Undead Settlement one is tied to Siegward of Catarina's quest.
  • The Catacombs of Carthus one drops a special soul that can be used in Soul Transposition.



  • Undead Settlement: find the tower lift of the right of the area and drop down mid-way onto some rooftops, then further down to meet the demon.
  • Catacombs of Carthus: after you break the hanging wooden bridge, go down using it as a ladder to find the demon near a mimic and amongst many skeletons.



  • Souls: NG 5000, NG+ (30,000), NG++ (??), NG+3 (??), NG+6 (??), NG+9 (??)
  • Co-Op Souls: ??
  • Other: Fire Gem, Soul of a Demon


Combat Information

  • Can be fooled with alluring skull, and be charmed with rapport
  • Weak against demon weapons
  • Get between its legs and make your way to the tail.
  • You can be aided by Siegward of Catarina to defeat one
  • You can be aided by a nearby Mimic to defeat one.






Strategy 1 (Melee)

Catacombs of Carthus: Run down the stairs to meet the demon and run around the perimeter of the first platform. Two skeletons will rise and chase you. However, they are agressive to the demon. Run past the demon and the skeletons will start to fight it. They do quite a bit of damage, but are easily killed by the demon. More skeletons can be found on the platform below the demon. Most of the skeletons have more than one life. Allow the skeletons to bludgen the demon. Usually by the time all the skeletons die the demon is either dead or very close to dead. Mop up the rest of surviving skeletons (if there are any).


Strategy 2 (Melee)

Catacombs of carthus: using alluring skulls, bait the demon towards the edge, so that it will drop off to the lower platform. When the demon drops below, use a plunging attack or a jumping attack to deal massive damage very quickly. the skeletons in the lower section should keep it busy if you need to run to the upper platform to repeat this as necessary.&nbsp


Strategy 3 (Bow+Arrows)

Undead Settlement:  Run to the building where the dogs are and stand on the balcony.  Shoot him until he dies.

Catacombs of Carthus
: Lure the demon to the door of the room and shoot from a bow.
The demon can prevail upon you to task and fall through the texture, later died there (reward and soul will be received by you)
Alternately, if you go to the ledge away from the door and shoot him, he may repeatedly attempt to belch fire at you, which can be easily walked away from to allow you to regenerate stamina for your volleys.  I defeated him in this manner with approx. 20 standard arrows from my Black Bow of Pharis +3.

Strategy 4 (Magic)

Undead Settlement: Run down towards the shack on the left. There's a narrow path down the left side of the shack. Keep going and get the demon's attention, attack with heavy soul arrow etc.. Then quickly run back the way you came, get close enough to the start and Seigward will activate. Let him start attacking the demon. Run back down past that shack and attack the demon from behind with heavy soul arrow, till dead.


Strategy 5 (Mimic)

Catacombs of Carthus: When you enter the room with the demon is in do not go down to him. Instead, continue on the path you are on until you reach the mimic chest. After attracting the mimics attention lure him down to the demon, who will be hostile to the mimic. The demon and mimic will both deal heavy damage to one another, usually with the mimic killing the demon for you allowing you to collect the soul of the demon. Be wary of the skeletons in the area who may swarm and kill you before the mimic/demon fight is over.

Lore Theories

  • This demon was one of many created by the Chaos Flame, but since said flame has died, along with the other demons born of the Chaos Flame, it is possible that it, along with the one in the Catacombs of Carthus, and the Old Demon King, are the only demons left. "Demons were born of the Chaos Flame, but the flame has not survived, and the demons are a dying race." - Soul of a Demon

      When I used Great Magic Weapon( 123 spellbuff from Sorcerer Staff +3) + Bandit Dagger( +4), I killed the fire demon in about 30 seconds, lmao. Possible weakness to magic or dagger spam stronk?

      • 11 Feb 2017 08:56  

        Found a glitch where pulling the Demon to the entry door (Catacombs) and triggering his jump attack will occasionally send him into a rampant ragdoll seizure plummetting through the map after he has been taken down halfway.

        This is an instant kill and did net me the would after about 40 seconds. Kill zone must be far down haha

          So I used the spook spell to sneak my way to the other building, it succeeded and hasn't set the demon and siegward dialogue, I have a funny feeling it could be one of the only things left that hasn't been discovered? Also mayhaps putting the fires out without being seen could potentiall help he situation? Gods luck dark souls peps :) :)

          • 22 Jan 2017 09:53  

            Undead Settlement, get the irithyl sword from the outrider at the bottom of the elevator. i think it makes good damage even not upgraded. I stand on the wall and attack him from there, while siegward was tanking him.

            • 06 Jan 2017 20:00  

              Or, run right past him and down the stairs at the at the end of the room. From the BOTTOM of the stairwell he can't hit you and there's a bonfire right around the corner. Easiest cheese in the whole game.

                If you dodge when he charges at you, you can get him to fall down to where all the reanimating skeletons are and let them go to town.

                • really easy magic win - should be on the main guide17 Sep 2016 08:06  

                  if you can lure the demon to the doorway before you met him (which is very easy), you can hide behind the door and he cannot pass, allowing you to kill him completely safely with any kind of magic (although pyromancy will take significantly longer for obvious reasons). he also runs back to the doorway every time he is hit, meaning there is no need to keep putting yourself in harms way to lure him back.

                  • Undead settlement drop10 Jul 2016 17:44  

                    Does the demon on the settlement drop its soul? I don't remember receiving nothing but on soul transposition I can se the items it makes (hammer and knucles) without ever acquiring it.

                    • Easy Catacomb Fight01 Jul 2016 02:01  

                      I managed to get all of the skeletons to kill the demon for me by agroing them and then running past the demon and up the stairs. It may take a couple of runs for the skeletons to win, but if they don't, they will take his health down a good chunk, making him easier.

                      • Cheap Strategy19 Jun 2016 19:21  

                        I'm sure other people have done this, but I actually accidentally came across this strategy. In the Undead Settlement, I had talked to Seigward, went half way up the elevator and jumped off onto the wooden platform. Then I saw Seigward was there now, sitting on the edge talking to me. I egsausted his dialogue and tried to climb down. When I got to the bottom, I suddenly noticed the demon and hid in a corner to think about my strategy. Suddenly, I heard Seigward say something like "No no, we should have waited! Oh well, I'll fight along side thee". Then I realized he came down to help fight the demon who was now coming after me and I tried to help him, that is until I realized Seigward didn't seem to have a health bar. After that I basically just sat in the corner and let Seigward beat the hell out of him. GG demon.

                        • Funny strategy28 May 2016 19:29  

                          when i encountered the carthus catacombs demon, i decided to lure it back up the stairway and close to the archway, i switched into the greatlance. after agressively baiting him to the point where one of his moves causes him to go forward too far, he will get stuck in the archway and slowly rise into the ceiling. when you run back inside, one of his feet can clearly be seen protruding through the ceiling near the archway. after enough damage was done with bow and arrows, he suddenly becomes agressive again and will try to reach you with his attacks. when you leave the archway again and head outside, his violent swings will cause him to rise further and ultimately clip through a part of the ground above sending him straight down into the abyss; causing his death.

                          • note19 May 2016 23:06  

                            In the catacombs of carthus fight, you can get the demon to use its fire attack on the mimic, which will result in the mimic becoming hostile and attacking the demon.

                            • Demon vs. Mimic03 May 2016 20:47  

                              The demon can trigger the mimic itself with its flame breath. Bait the attack over to where the mimic is at, and you can safely stay up top while the mimic rushes down to engage the demon. Mopping up the survivor is easy after that.
