Combat Information

  • Weak to Bolt and Fire.
  • Strong against Arcane.
  • Magic deals Arcane damage, includes "Rain of Flesh" - "Vein Shot" - "Blast"
  • To start the fight go to the second level to remove the casters. Be careful not to knock them to the first level as they are likely to survive the fall.
  • Plunging attacks from the second level are very effective against the boss.
  • High damage can be dealt to the boss after it collapses. Make sure to strike the corpse protruding from the top of the boss while it's collapsed.
  • Should you hear the torso caster on the back of the boss howl as he channels, back off immediately. It is about to do an area of effect attack that deals high damage. Avoid this by backing away or running to the back end of the boss.
  • Last half of the fight if the boss stops and appears to vomit, move to high ground immediately to avoid the flood of vomit which swamps all of low ground and deals massive damage. Sprint to one of the raised side paths or one of the staircases at the back of the arena.
  • Fighting him along his side between his legs is a recommended approach. Stay closer to the back of him to avoid the burst damage spell his raised head can cast. Roll out when he starts thrashing around of when your health is at about half. Especially if the casters are still active it is a good idea to stay above half health when meleeing to avoid getting trampled to death.
  • After you've struck the boss with a combo he may summon a rain of body parts which tracks you. Back step or dodge until the attack stops. This can cause a lot of damage so it's best avoided.
  • Adopt a hit-and-run tactic. The fireballs only do menial damage, and won't hit you often at all if you keep moving. Run, hit him with a dash strong attack, and run away, slowing to a walk to regain stamina. One should always keep on the move, and keep distance unless you're closing in for a pass.
  • Like Amygdala, the larger limbs at either end of the boss can be weakened and broken. You'll see blood coming out of each leg with combo'd hits. Focus on one limb and you'll break it, causing more damage.


Attack Name Attack Description & Counter
Flailing Corpses All limbs on the body of the one reborn start furiously kicking and swiping in all directions, literally every limb on its body flails.
Rain of Flesh Body parts fall randomly atop the player's head and deal damage.
Vein Shot Charges up massive ball atop his head that he then uses as a precision projectile.
Sweeping Corpses Reaches up to the bell women and swings its more massive limbs in a sweeping motion.
Discharge A stream of putrid liquid is discharged onto the arena floor. The slow speed of this attack gives ample time to move to higher ground.



This can be an easy boss if approached correctly. The player should first take care to run past the boss and up the stairs in the corner area and kill the Bell Chime Maidens that are buffing the boss. This approach will be similar to the Tower Knight of Demon's Souls.

Once this is done, head back to the boss arena and engage the boss from proximity, with a weapon that gives you either quick successive hits or a heavy knockback effect. You will want to target his mid section, making use of the specific spot between his middle legs where we cannot easily hit you. Alternatively pick one of the larger legs and focus on it entirely, weakening it for a lot of damage.

If the boss begins discharge or Vein Shot/Rain of Flesh you should run around the arena to counter, and Flailing Corpses is easily countered by backstepping away. This boss is easy to stagger, and weak to fire and bolt damage, to take advantage of this.

Notes & Trivia

  • The arena of this boss and the placement of the Chime Maidens is reminiscent of the Tower Knight and the archers in Demon's Souls; furthermore, Tower Knight's weak spot is his legs while this boss is entirely constructed from leg parts.
  • The One Reborn resembles Nito from Dark Souls and Dark Souls II's The Rotten. Undead amalgams first appeared in Demons' Souls.
  • The One Reborn's much resembles the song "" from the movie Prince of Egypt.

      If you don't know how to beat him easily, then just do the following: 1) Kill the chime maidens on top. 2) Wait in the middle of the balcony until he is right below you. Jump down and hit him with a falling attack. Hit him a few times afterwards (maybe he crumbles down, so you can get a few more hits in). 3) Get on top again. Jump down again. 4) Repeat.

        I think this boss is actually optional. You can get the tonsil stone to get to the lecture building floor 1, then go kill Rom, then when you're teleported to Yahar'gul, you can re-teleport back to the first floor of the lecture building, where you can access the nightmare of Mensis, killing Rom would be required since the Mergo doesn't spawn until doing so. But everyone thinks this boss is required but it actually is skippable. You have to take the proper steps, but nonetheless optional.

          What I did was just get a coop guy and be total cowards and hide behind the pillars. He's so big we could both hit him. It took a while but we won without getting hit more than 2 times each.

          • no purple sky and red moon05 Jul 2016 08:34  

            I was in YAHAR'GUL once and the sky was purple and the moon was red, but I didn't know about the one reborn so I went and killed amygdala the celestial emesstery and ebritus daughter of the cosmos and I went to go back to the area because I found out about the one reborn but the sky is black, the hypogean gaol gate that heads towards the boss isnt open anymore and I can even see any enemy's in the area besides the ones that are there in early game, also the elivator isnt going down, I have it at the top and it won't go down

            • Leaping attacks05 Jul 2016 08:34  

              If you have a heavy weapon like a transformed two hander, you can stagger him pretty easily with leaping attacks. Just stay toward his puking end so the corpse end doesn't do those ridiculously long range swipes. You can run to the stairs if he does the aoe vomit and are already a good distance away from his other end so you can avoid the red aoe blast. Just strafe like crazy to dodge his organ summoning and leap attack right after he does one of those. I was able to stun him with the greatsword every and every other leap attack which left his corpse part wide open to charge strike, which id massive damage to him.

              • Where were the stairs?05 Jul 2016 08:34  

                I didn't even realize I could kill the witches, so I just Kirkhammered him into submission while heal spamming. The cannon really helps too.

                • Boss guide video05 Jul 2016 08:34  

                  I don't think I'm allowed to edit the wiki page because I guess I'm a 'random'. But hopefully its fine to post a link here. If its not okay, I'm sorry, but I just want to help people =) <br/>

                  • Feeling a bit silly now05 Jul 2016 08:34  

                    It took me a few tries because I never realized you could scale the walls and take out the casters and use plunge attacks. On the flip side, when I just hugged the non-leggy part of his body and hacked away, he used the burst AoE only once, and never vomited. One thing I did that's not mentioned here, is that while hugging the boss, I would fire the Flamesprayer whenever I ran out of stamina, and keep that up until it had regenerated. I can't find any use for the pistol with these huge bosses, so I might as well turn my gun slot into a pure DPS tool. Didn't even go through all my QS bullets before he was dead.

                      Forgot the name, and not gonna go spending time to look it up. but I believe it was Baby ankles.

                      • How to treat the One Reborn like a joke05 Jul 2016 08:34  

                        If you run past him and head up the stairs, take out the bell chimers, then head to the upper area above the fog gate and wait for the One Reborn to approach. You can VERY easily plunging attack the boss from this point, even healing through the fall/corpse attack damage by regaining you blood via the plunging attack, and simply run back up, rinse and repeat. Just make sure to heal if you take a corpse to the face, and avoid the gore that falls from the sky. Easily defeated him first try with this method.

                        • Drop fall not working05 Jul 2016 08:34
