The One Reborn (再誕者 Saitansha lit. "The One Reborn") is a Boss in Bloodborne.

The One Reborn information

  • The One Reborn is a colossal undead mass. He is assisted by red Chime Maidens (killable).
  • The Chime Maidens shoot fireballs and heal The One Reborn using purple projectiles.
  • You gain 1 Insight from discovering this boss and 3 Insight for defeating him.
  • You can summon the Old Hunter Defector Antal (The Church Pick Hunter) with the Old Hunter Bell to assist you in battle. The summon "sign" is located in front of a crashed carriage near the fog gate. For more information about his human location, look at the Wiki page of the Church Pick.

  • Yellow Backbone x3


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.
  • 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

- One thing you can do before the boss battle begins to make it easier is to go to the glowing, kneeling corpses in the area previous to it and "activate" them. To do this you need to step into their rings and let them damage you three times and they will stop glowing; go around and do this for each kneeling corpse until none are glowing. Doing this will take away a couple of moves from the One Reborn: Rain of Flesh and Discharge. (At least it happened in my game, so full confirmation from others are needed.) 


(( Please respect these video posting guidelines))


  • A being reborn, as part of the Mensis Ritual.
  • Its internal ID name is "HalfBakedDevil".
  • Some believe it to be the reincarnation of Gravelord Nito.


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.

      I think my fight glitched, because I basically just glued myself to his side and hacked away. Every time the maidens hit me with anything I wailed on him to get my health back. I kept expecting a massive AOE....but... I figure it was either a bug or my boss RNG was insane.

        I believe the bosses name is an innuendo to what it is. My theory is the boss is made up of ALL the victims of those abducted by the college of Mensis and sacrificed. Anyway, “One Reborn” can also mean “Reborn as One.” Everyone sacrificed has been reborn as a single living entity. Anyway, I’m HP Lovecraft lore, the old gods delight in sacrifice, especially human sacrifice and I suspect that was the prime reason the College of Mensis was kidnapping people.

          This says back off immediately when vomit flood comes, that’s bull*****. It covers the whole floor! Run up the stairs to avoid

            Old Hunter Yamamura is also up for summons on this one. If you have completed Hunter's Nightmare, at least. I found this out whilst on NG++. His summon sign is behind a carriage, by the tower with the ladder!

              I slayed him just today one more time, and somehow it made me thinking... May this resembling to Orhpan of Kos? Just look at this. Looks like him (I mean that part of the body casting things, screaming). And right after him is Micolash, who were praying to Kos. So, we killed Orphan of Kos (or someone did before us), "reunited" him with the sea that "takes everything". I guess "everything" was corpses, many af (look how many drowned ships at the coast). We dispel his spirit/soul into the sea, and some part of the dead got it's pieces. That's why he's in that form now. Besides, there was a lighthouse. Lighthouses come with bells that indicating where it stands (besides the light). A beacon. Witches with bells played the role of this beacon, indicating where he should be. Aaaand here we go: Reborn means "born again", come back to life. Someone had to die before. And I see only one option with all these guesses. It may be barely readable, I'm sorry for this. English is not my native language, and I tried to match these thoughts just minutes ago and while I write this. I may be missing something tho, feel free to destroy this theory.

                Charge up the tonitrus, stay under the torso and beat his meat. Go to the stairs to heal/avoid aoe attacks. Second easiest bossfight.

                    So Easy! As long as you can summon Defector Antal to distract The One Reborn while you take out the Chime Maidens, and then whale on it together. Back up when it throws a tantrum and you're good!

                      At the Advent Plaza go towards the building with the members of school of Mensis, on the either side of the entrance you can see weird statue like things some partially covered in cloth. The structure and general design of those might hint at them being failed attempts at creating the One Reborn, as according to Darkbeast Paarl description, the school of Mensis tried several times to create a Great One.

                        I just used the Beckoning Bell and a cooperator came. I summoned Defector Antal, and charged in (team of 3 people). The player and me attacked the Chime maidens while Antal was dragging attention from the One reborn. We eventually gang-banged the boss (Antal still alive) with Bolt weapons, pretty easy since each player gets a weak spot from the One Reborn. But that of course, needs online play...

                          The One Reborn... The First of The Dead, the Great Dead One reincarnated. It's not a coincidence some of the enemies in this area leave behind pinwheels on the ground upon death.

                            How the hell do you avoid his arena spanning vomit attack? Or is there some sort of attire i could wear to give me better resistance?

                              The player notes aren't correct in the slightest so please take them off the page. Out of 35 runs against The One Reborn, all 35 times I "deactivated" the glowing skeleton pools and of the 35 runs only 3 had any noticeable behavior changes. The vomit attack didn't happen at all during those 3 but that was the only change. During a few runs the rain of corpses happened less sometimes.

                              tl;dr please take the incorrect information down. The glowing pools do nothing at all to the boss fight.

                                Good ol' Granfalloon--and I don't mean it just looks like the boss from Castlevania, I mean this thing really reflects Kurt Vonnegut's definition of such a conglomeration: "A proud and meaningless group of human beings." My interpretation was that this creature represented how the School of Mensis became a mindless, directionless group of philosophers who had lost sight of their own intentions. Instead of working with the Choir to "heal" Yharnam's blood, they became obsessed with the power that their pursuit of knowledge had granted them. This is illustrated quite clearly in the Student Set, which declares that the scholars had become focused "not on thought or knowledge, but pure pretension." By quite literally brainwashing Yharnamites, the School of Mensis relies upon esotericism to maintain their status, and the One Reborn is the image conjured by the Hunter's interpretation this conflict. Even the name, "One Reborn," seems to represent the abolition of the self and subjugation into a social structure.

                                    This is so weird. I haven’t had problems with any boss prior to this. Normally beat on the 1st or 2nd time but this one for some reason has been killing me. Never a problem down to the bottom 1/3 or 1/4 health but for some reason after that shit hits the fan.

                                      I have quite the awesome lore theory on this thing, bear with me, it appears in advent plaza, which afterwards is the only way to access the nightmare of mensis, note that it appears out of a void, and that the worlds are all above each other, my theory is that advent plaza is below the school of mensis, and TOR was kept in the void below the school, i think it was a vessel for the brain of mensis, but your appearance interrupted the ritual, note that there is a lever that allows you to drop the brain into the void, but you just pulled the lever all the way back and the stress dropped it, maybe that lever was supposed to lower the brain slowly and you basically fumbled that, what was supposed to happen was TOR was supposed to be summoned than the brain lowered onto it, upon which it would become a true man made great one, mensis. i assume it would be called mensis because we are given no clues as to why the school is named as such (for the record i do know what the word actually means) but my assumption is that the brain of mensis isn't just a title, its actually the brain of something/one CALLED mensis.

                                        This was literally the easiest boss. I beat him on my first try after accidentally summoning the guy. I just stayed behind him.

                                          Am I the only one who thinks that the one reborn is the orphan of kos , just "reborn" ? look at the two , the similarities in their appearance is obvious to me.
