Combat Information

  • Weak to Bolt and Fire.
  • Strong against Arcane.
  • When at the second level, the boss can perform the attack "Swinging Corpses," (Scroll below for more detail) so make sure to be paying attention to the One Reborn while attacking the casters.
  • The corpse at the top, even while not collapsed, takes more damage from projectiles than the rest of its body.
  • 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.
  • 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.
  • If the boss stops and appears to vomit, move away immediately. You'll avoid the flood of vomit.
  • 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 areas and kill the Chime Maidens that are supporting the boss. This approach will be similar to fighting Tower Knight in 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 he has a hard time hitting 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.


Player Notes

  • It's easiest to get to the boss from the first lantern through the elevator instead of trying to take a closer lantern.

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 theme much resembles the song "The Plagues" from The Prince of Egypt movie.

      Never really understood this guy's deal outside of getting stunlocked and occasionally puking on you or shooting a blood thing for middling damage. Even at 27 Vitality, there's just not much challenge if you play fast and aggressive. Across multiple builds (Basic quality, Gun, Arcane), One Reborn just eats it and dies without much of a fight.

      Or, as the message I found in its arena with 500 ratings put it: "Pitiful, really." (Gesture: Shake Off Cape)

        Am I doing something wrong? I beat him twice already, both on different quality builds no sweat. Now I’m playing on a str/arc build, and I barely do 200 dmg and for some reason his ground poison attack can kill me from across the arena

          Is this thing supposed to deal so much damage? I keep reading up that its easy, but I get caught in something like its puke and end up dying very quickly, everything takes out at least a third of my health bar.

            Oh you can go up there and kill those ladies, huh? Whoops, killed him without realizing. Which was satisfying in it's own right, enjoyable fight. Killing the ladies might have made it too easy.

              Here's my theory: the mensis ritual's purpose is to create bodies for great ones of the nightmare to puppeteer. Obviously the snatchers are kidnapping people and bringing them to Yahar'gul so they can be integrated into these amalgams. The only great ones we see outside of nightmares are lesser Amygdala, Ebrietas, Rom, and the Celestial Emissary. Rom and the Emissary are "artificial" great ones of sorts as the Emissary was created by the Choir and Rom was born at Byrgenwerth. Ebrietas didn't ascend with the other great ones for whatever reason. However, Amygdala seems to exist in both the waking world and the nightmare, with the lesser Amygdala providing passage into nightmares. My guess is that Amygdala is supervising the ritual in place of the other great ones as she is the only one who can commune with the great ones of the nightmare and observe the ritual in the physical world. If you look at the living string description, it describes the brain of mensis as rotten. The brain also looks like a giant amalgamation of heads and eyes with some random appendages sticking out at various points, very different from the 2 other great ones in the nightmare, being Mergo's nurse and Amygdala. It's possible the brain of mensis was an earlier product of the ritual which is why it's completely immobile and unable to defend itself when dropped into the pit. Anyways, that's enough insane rambling from me.

                One of the best OSTs. Since the boss is actually pretty easy, I like to finish it off by running up the stairs to the connecting bridge, dodging the blood missiles, then doing a plunging attack when it gets close.

                Creepy as hell when it "stands up" to reach the upper levels, though.

                  You can also summon Yamamura for the fight. He's to the right, behind a carriage in the area directly before the fight. Idk if the League rune is required, but I had it. Oddly enough, I didn't get a summon for Antal, though.

                    "Some believe it to be the reincarnation of Gravelord Nito."
                    Yes, we should call those people - if they even exist - morons.

                      if you somehow are struggling to beat this boss, use fire paper and beast pellets, and tear apart one of its crotches

                        Given the known Bloodborne lore and the absence of such, I have a theory the One Reborn was the/a Moon Presence, as partly indicated by its intro cutscene. Since the one we're aware of is within the Hunter's Dream, it doesn't reflect it's physical presence in the "real" Yharnham, but is possibly Gehrman's memory of the Old One empowering his dream.

                        Considering the amount of mutations from beasts to man-beasts and from celestials to celestial kin, if we assume the Amygdala and the Moon Presence are similar, it's possible someone experimented with some of the Old Ones and recreated an Amygdala/Presence with human blood and ended up creating... this - the rebirth of an Old One.

                          If you have the Blade of Mercy you can kill the maidens, lock onto his middle section, stand between the joints of two of his legs, and R1 spam until he dies. Did this my first try only had to back off twice to heal.
