Demon Location

  • 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.

Demon Combat Information






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


Notes & Trivia

  • The Demon in the Catacombs can also be "cheesed" by luring the Demon up the stairs and towards the doorway you entered from.  Once he reaches the top of the stairs, he will slowly walk back down the stairs becoming hostile only after he has made it all the way down.  During this time, he is open to attack.

        What will happen to Siegward if I one shot that fire demon in undead settlement? I try it by using Millwood bow with red tear morion dragon form + hawk ring, and aim to headshot snipe it down before it trigger Siegward dialogue, but I failed, it remained last hit

          It says that you only get "Soul of a Demon" from the one in catacombs. But I can confirm this is incorrect. I have only reached road of sacrifices but I have this soul in my inventory and can transpose it. I think I probably got it from the drop at undead settlement.

            Demon in catacombs can be cheesed using a bow this may take longer but there is a slight chance the demon will glitch into the ceiling and if you walk to the bridge you will see the demon's head use an arrow against the head and it will fall into the abyss.

              you dont even need to lure the mimic yourself in catacombs. the demon seems to use the fire breath attack 100% of the time as long as you haven't used the stairs yet and with some messing around and hitbox janking, you can get a fire breath to hit the mimic and it'll be auto agro'd to the demon. just be careful not to let the fire breath hit the mimic too many times are it'll die before getting to the demon

                Idk if this is a bug but when the demon chased me all the way to the mimic chest(hasn't transformed yet) it would step back in fear and wouldn't attack at all. Instead it would repeatedly chase and move back.

                  Finally got the mimic to follow me down the stairs without getting flamethrowered at the same time, and this mother*****er jump kicks me *through* the demon, and then the demon one-shots us both LOL

                    Does it look like a reimagined Taurus Demon to anyone else? Considering how the Stray Demon miniboss looks different from DS1 as well. Of course the demon ruins depict the original versions of both.

                      Fun fact: the skeleton at the feet of the one in the Catacombs, under the boss arena before the Smouldering Lake, will attack the Demon. I don't know if the Demon hit him or what, but I went down the stairs a little too far while cheesing the mini-boss (letting him come up the stairs, hitting him as he slowly walks backwards down it, then hiding to the right when he spits fire and repeating) and for some reason the skeleton stopped attacking me and finished off the last few hits on the Demon for me.

                        Immune to frostbite is a lie... i tuned him off every time i hit with irythil sword (he become whiter). Then he uses somekind aoe blast to turn his fire back on. Absolute abuse strategy to just turn him of with that sword, place a few hits, run away from blast and come again.

                          Just going through NG++, and tried to bait the Mimic to help out for the Fire Demon on the way to the Smoldering Lake. That Mimic single handedly destroyed the Demon. They got locked into some sort of animation loop where the Mimic kept getting it's large golf-swing kick attack in, staggered the Demon, and the Mimic went straight for the kick again while the Demon tried to wind up for an attack before getting staggered out of it again. Yep, that Mimic stagger locked and killed the Demon for me, all by itself. Best Mimic ever.

                            Magic and lightning also do respectable damage against these enemies. Also, you can lure the Knight Slayer Tsorig invader to the demons area and use a Seed of a Giant Tree to make them both fight.

                              a bit of a paradox that "chaos" is based on faith and intelligence but the "chaos-creatures" have always a huge chunk of str within their builds if I look at their weapons (Hammer, axe, Demon fists).

                                I got him to destroy the bonfires around him by dodging his attacks when near one. But Seigward died. It could be part of the key to making him less “overheated”. Maybe this in combination with some sneaking and Rapport can make him friendly without Siegward dying. Maybe show up befor Seigward?

                                  Love leading em into the skeletons and letting them butt***** em. Mimic vs the demon seems to be weird though. Both the mimic and demon seem to be able to just about one hit each other. Mimic with that spin kick, while the demon and the flame breath. Least from the times I was able to get them to fight.

                                    Discovered a potential glitch when fighting in the Catacombs. I ran over to the mimic to try to get him to use the fire trick, but he decided to run up the stairs to try and melee me instead. I think he's too tall for the walkway so he got stuck about halfway. I attacked him from range and occasionally he would become aggressive and charge at me, but if i took a step forward he would be pushed back to the same spot where he started glitching. Just rinse and repeat until he died. Any one else encounter/can replicate this?
