Mephistopheles is an NPC in Demon's Souls and Demon's Souls Remake. NPCs are the various characters that are encountered by the player throughout their journey. NPCs provide information, others are quest givers, while some are categorized as Merchants and/or Blacksmiths whom you can trade with or request for certain services.


Mephistopheles is a grim woman with a deadly secret. She seeks the assistance of Yurt, the Silent Chief, and later the player if Yurt is killed. She also wishes the death of key NPCs in the Nexus; specifically, those with knowledge of the Soul Arts.

Upon completion of her requests, Mephistopheles will say that the Order of the Soul has commanded her to remove all those who know the ways of Soul Arts from Boletaria, the player included, in order to keep the ancient rite a secret.


Mephistopheles Information

She offers you rewards in turn for assassinating other NPCs:

  • If an assassination target is already dead, Mephistopheles will skip to the next person on the list. You do not receive a reward.
  • You have to talk to her after every assassination and be handed the next task to actually receive the individual rewards.
  • When all assassinations are complete and you speak to her for your reward, she will attack you after giving you the reward
  • NPCs you assassinate are gone for the rest of the game, but will respawn once you complete the game and enter another cycle (once normal conditions are met for them to move to the Nexus). If you've killed Freke and Yuria you can no longer change your equipped Magic. If you kill Urbain you can no longer change your equipped Miracles. Once they are dead, you will have the same Magic and Miracles until you finish the game and beat Phalanx in the next cycle

If you kill Mephistopheles, she will drop the following:


Mephistopheles Location: Where to Find Mephistopheles

The Nexus, second floor using the outer staircase (ie. not the one with the Archstones).

To unlock:

Note: If you still can't see her, exit the Nexus and return. If you fulfill the requirements while you're inside the Nexus, Mephistopheles will not appear until you re-enter.


Assassination Sidequest and Rewards

  1. Saint Urbain, Worshipper of God and Acolyte of God - Stone of Ephemeral Eyes.
  2. Sage Freke and Freke's Apprentice - Stone of Ephemeral Eyes.
  3. Patches, the Hyena - Colorless Demon's Soul.
  4. Biorr, of the Twin Fangs - Colorless Demon's Soul.
  5. Ostrava of Boletaria - Talisman of Beasts.
  6. Yuria, the Witch - Foe's Ring.


Assassination Strategies

Many of the NPCs in the Nexus can easily be killed by casting normal spells (Poison Cloud works a treat) or using your melee weapon of choice. However, a few of them merit special attention:


  • An easy way of killing everyone on the list as quick as possible is using the Clever Rat's Ring and Morion Blade  trick. Use your fastest weapon, that deals a lot of damage and keeps them locked in a combo. Straight Swords are good for this. You will do massive amounts of damage per hit and maybe kill them before they can react, if you have enough stamina. The only exceptions would be high hp characters like Ostrava, of Boletaria and Biorr, of the Twin Fangs.
  • An easy way for magic users to kill everyone is call up Homing Soul Arrow and a sword with a strong thrust. Once you thrust, the Homing Soul Arrow will target. If your magic is high enough all five shots will hit. If they survive they shouldn't need more than Phalanx Archstone quick swings.
  • All of the targets are vulnerable to Death Cloud, allowing you to simply cast the spell and wait if you have the patience or are simply having problems killing them. (Note: As you accept each assassination request the target will remain friendly until you attack them, however most simply do not notice if you use Death Cloud, except Ostrava who remains friendly until under 25% health. At which point he becomes hostile)
    For ranged assassinations use a mixture of the Clever Rat's Ring, Morion Blade, and Thief's Ring with a strong bow. Shoot once and the NPCs get up. They remain standing in place since they don't recognize an attacker. A second shot should kill them. Just remember to kill Urbain's and Freke's followers first, since they'll turn hostile if you defeat their respective masters.
  • Every NPC can be killed in one hit using Soulsucker.

Freke & Urbain

You don't want to give Freke or Urbain a chance to counter-attack. Ambush them with God's Wrath and then knock them down with the Meat Cleaver; or a similar large melee weapon, when they try to get up. You should be able to kill them before they can gather themselves.


Don't get too cocky against Patches. His spear is a deadly weapon, and he also has an Adjudicator's Shield to regenerate his hit points, so he's not quite the pushover that he might seem. Though, as long as you're careful, you can take him out just about any way you want.


Note: If you have rescued Biorr, the last chance to kill him is right after you have defeated the Blue Dragon. If you leave for the Nexus without killing him, or walk too far away from him, he will disappear for good.
Biorr will also stay in his cell for the duration of the game, as long as he's not rescued. If you have already killed the Blue Dragon or Old King Allant, he must be killed right after being released, since going to the Nexus will make him disappear for good.
Possible bug: Sometimes Biorr will not attack you at all even if you do repeated 2 handed heavy melee attack or backstab attacks.
If this happens, you will still get the reward from Mephistopheles. This only happens in The Nexus.


Note: Speaking to Ostrava and making him suicide in Penetrator Archstone just before Old King Allant, wont count as a kill, thus you wont get the reward. Walking past him will also result in him killing himself, so you'll have to attack him while he's sitting in the staircase, without talking to him. He will still drop the Mausoleum Key when killed.


Unlike the other two spell trainers, Yuria has a wicked temper, and will become hostile within the first few attacks. If you ambush her with God's Wrath, she'll quickly recover and counter with Firestorm, which will likely kill you, regardless of your Soul Level, equipment, or defensive spells. To play it safe, get a good bow and some heavy arrows, hide behind the Archstones (the Shrine Of Storms side of the steps), and slowly wear her down. She'll throw fire at you, but from that distance, it's easy to dodge her attacks. If she positions herself out of range, walk over to the other side of the Nexus, behind the place where Urbain's female follower normally sits, and you'll have a clear shot at Yuria until she moves back to her original position. Casting the Anti-Magic Field Spell and using a melee attack also works against Yuria.


An easy way to kill Mephistopheles is to keep her just out of melee range and zap her with Soul Arrow until she dies, blocking her attacks with a good shield. Just don't let her touch you, as she will use the Soulsucker Spell.



Use Mephistopheles as an easy way to delevel. You can be soul sucked up to 4 times during your battle with her. This is most easily achieved if you keep within melee range of her with your shield up. Once you have blocked Phalanx Archstone of her attacks and she has staggered, she will usually pull out her catalyst and cast Soulsucker

When she pulls out her wand, keep your shield on her left shoulder. She will either dodge or strafe. If she dodges walk up and place your shield on her left shoulder again. If she strafes she is going to cast soul suck. If she leads you out on the edge by the staircases, back off. Let her follow you back into the upstairs room. She may roll/dodge from the ledge all the way down to the nexus ground floor. This will certainly kill her for the game cycle.


Mephistopheles Dialogue

First encounter:

  • I can see, that you have killed in the past…
    No one can blame you for that. Demon souls are too precious to relinquish.

    There is more work for you.
    I want you to kill the Witch, Yuria.

  • (yes/no)
  • So, you've completed everything, eh?
    You're what they might call a miracle worker.
    Lastly, I must only kill you, and the secret of the souls shall be eternally safe…

When attacked

  • Are you mad?
  • A fool such as you is a rare thing…

When the player is killed

  • Fool. Did you really think that you were special?

        needlessly detailed explanation for getting her to soulsuck you quickly:

        the easiest trigger for getting her to pull out her catalyst is to stand by her and use items. Instead of constantly wasting grass just put an item on your hotbar that you cant use, like the white eye stone, and just stand in front of her spamming it and she should try to suck you pretty quickly. she only has enough MP for 2 casts, however. after you've been sucked twice you can either let her kill you (also accelerated by walking up to her and trying to use items as it prompts her to attack you after shes out of MP) or if you're on the remake version its faster to just save and quit right after the second suck and run back to her as saving and quitting resets enemies so her MP will be back.

          Once she's appeared, does she disappear if your character tendency changes back to White, or is she there permanently once you spawn her?

          • Anonymous

            Ok yeah cool she's pretty hot, but wtf does, and I quote "If they survive they shouldn't need more than Phalanx Archstone quick swings." mean??? Lol must be a typo

            • A few words about PBWT and Mephistopheles questline.
              1. If you are not interested in rewards and just need the ring for the Platinum you can kill a few targets from her list (but not the last one, Yuria) even before starting the questline, to drop your CT to PB. She will simply skip NPCs you have already killed and ask to kill the rest. No big profit, just a time-saving trick.
              2. After killing Yuria but before talking to Mephistopheles free some space in your inventory for the ring. Because (as it happened to me) you don't do this, talk to Mephistopheles, she will give you the ring, the game will ask you "if you want to take the thing and move it to your Nexus stash automatically because it will overburden you blah-blah-blah" and your brain may lag a little, while the Mephistopheles herself had already become a foe and planning how to settle her knife between your butts. So you may get killed and I have no idea what happens to the ring you haven't picked up. Better not risk.

              Huge thanks to Need_help4_Platinum for saving me a few days/weeks of grinding through NG++, NG+++, and so on. I can finally rest of this game. And I really wish you all the luck and to get that platinum sooner.

                I made a simp assassin build just for her, and then she tried to kill me. I still love her though, anything for my goddess.

                • Anonymous

                  They made her look so hot in the Remake, oh my god. Finally got around to getting pure black tendency on my character, and dear lord she has such a perfectly modeled face I wish we could see her without the mask. Look at those lips oh umbasa! Her outfit is the best in the game too, I guess now I have to make a female character. Just great..

                    If one of the npcs is already dead due to a quest or another reason, would she just skip it and go to the next and I'll still get that ring in the end? :)

                    • Anonymous

                      This page is somewhat misleading. Based on the order of assassinations listed I thought from the moment I had encountered her, I had to go for Yuria first. Now she's gone, and I'm out of a Foes Ring.

                      • Anonymous

                        Patches disappeared from the nexus. I assume Yurt killed him at some point. Now I'm doing the assassination quest for Mephistopheles and I guess I can't finish it?

                        • Anonymous

                          I believe the notes for Ostrava are incorrect for the remake. I killed him on the stairs in 1-4 without speaking to him. I got the mauseleum key, but I didn't get the reward, which sucks because I'm doing a mag/faith build currently and wanted that reward. She just skipped his mission and went to Yuria. I think maybe Ostrava needs to be killed in the Nexus.
