Carthus Sandworm is an Enemy in Dark Souls 3.


Enemy Description

  • A visually impressive mini-boss that guards the entrance to the Old Demon King.
  • Erupts from the ground if you turn left upon entering the Smouldering Lake.


Combat Information

  • Will damage you if you stand too close to its moving body, or if you get caught by its lightning breath.
  • If Giant Avelyn is still active, player  can easily bait it to shoot Sandworm from a safe area behind any rock killing it with ease. Video Example. Therefore, it is adviced to not shut down Avelyn before killing Sandworm.
  • The Sandworm is unable to attack if you stay on the solid rock behind it.
  • If the Avelyn is taken out the Sandworm is easily baited into melee. Just wait for it to use its lightning attack and run up to hit it until it starts to move again and back away. Repeat as necessary.
  • It is advised to snipe at the worm with a bow of choice.
  • There are openings in its attack patterns for melee attacks. The worm has to stop moving or you'll be knocked back.
  • Cannot be lured.
  • Cannot be Rapported.
  • Weak to Thrust, Magic, Dark and Fire.
  • Resistant to Lightning and Bleed.
  • Immune to Frost and Poison/Toxic.

  • Souls: NG (6,000). NG+ (18,000) NG++ (19,801) NG+5 (22,501)
  • Is the same Worm that is mentioned in the description of the Yellow Bug Pellet.
  • Also might be a reference to the Shai-Hulud (or Shaitan later in the books) which are giant sandworms from the Dune saga writen by Frank Herbert.

      It's implied it could be Solaire but a Sunlight Maggot wouldn't transform him into what is seemingly a Chaos Demon/Centipede. Not to mention Canon doesn't have Solaire dying, his gear was well taken care of. Probably left over assets. Probably a poor attempt to tie in the Miracle, the unused asset and remove the Arch Peak Boss ties to Solaire.

          A bit of trivia: This creature is possibly based on the Mongolian Death Worm, a cryptid that is said to be a large, worm-like creature which bursts from the sand to attack prey with bolts of lightning.

            A way to kill the sandworm if you don't want to risk being hit by the ballista/giant avelyn is to stand on a cliff that is right next to the Demon Ruins bonfire and use a bow. Here, the ballista cannot detect you. Even if it could, it would simply hit a tree.

              I assumed that since the sandworm is guarding the Shield of Want, its description of a mad king that became a "soul eater" was referring to the sandworm itself.

                I didn't even know about the hole in the middle of the lake leading to the Demon Ruins when I first played, I just charged right past the worm and somehow survived, lol. I also didn't bother killing it in NG+ because it's just cool to look at and it doesn't really cause any problems unless you get too close.

                  I just stand behind it after the Avelyn is down and spam heavy soul arrow into its back, takes a while but it can't damage you

                    Extremely weak to Sorcery, go onto of the hill where the entrance to the Bonfire is so the big ass arrows don't hit you, and blow him away.

                      It actually IS possible for the sandworm to turn around, ofcourse this was a glitch, me and a friend of mine got to witness this firsthand. Unfortunently I have no living I guess I hope you take my word for it?

                        Why04 Oct 2016 16:16  

                        Why do some people out there believe that this random ass sand worm in the smoldering lake is everyone's favorite sun bro Solarie. Is it because its shoots lightning from its "mouth" and that it drops lightning stake when you kill it or let the giant cross bow kill it.

                          Weak to Dark. Can bleed. Can also be poisoned and intoxicated. Melee is the worst option; just use a bow and poison arrows. Pyromancers and miracle casters with Gnaw will have an easy time with this fight. Not sure about sorcery, haven't tried it.

                            This worm is really straight out of the Dune novels, including lightning.Not that this makes it any less fun.

                              Because you would need inspiration from elsewhere, to create a giant worm... Jfc, not everything in this game is taken from elsewhere. If I read one more comment about nameless King being goku, I'm done.

                                Just run left where the fog door is. The snake won't be able to reach you but the ballista will keep firing. The arrows will pierce the snake on the way, but they will still reach the ground so dodge rolling is needed. But i found a small elevation in the ground, so staying behind it will prvent any arrows from reaching you.A few arrows more, and the snake will die
