Combat Information

  • When health drops below 70%, Phase 2 initiates, but only becomes more aggressive during Nightmare Veil.
  • Do not fear her flurry attack where she swings all of her blades- it may seem intimidating, but if you can run around to her back, she can only hit you a couple of times from there, and you can easily regain that health by attacking. It's also the best time to lay down some heavy damage.
  • At an unknown trigger, the nurse will create a purple fog that engulfs the area, and a clone will appear and perform an attack every time the real Nurse attacks. After about a minute, this fog will dissipate, as will the clone. During the fog, the clone will warp around the arena (typically behind the player) in an attempt to catch the player off-guard. While the original uses a variety of leaping and long-range attacks, where her arms extend to extreme length. During this part of the fight, the bosses' back is often left wide open, providing opportunities to deal massive damage.
  • The clone can be destroyed by just a single attack, if you are using a fast weapon, you can destroy it before it can attack and go back to the  real Nurse to get in easy damage.
  • When the purple fog appears, lock onto the original Nurse and evade counter-clockwise. She will always teleport to the player's left side, and won't be able to keep up. During subsequent fog phases, both the Nurse and the clone will teleport to the players right as they run counter-clockwise. The strategy still works perfectly though with the occasional jump/roll added while moving.
  • It is possible to prevent the purple fog if you can stagger her while she is casting it.
  • It's also possible to prevent the purple fog by 'dodging' it, as it registers as an AOE attack.
  • Evade toward her left side to avoid many of her attacks. Getting to her back side guarantees safety from most of her attacks.
  • Poison Knives are very effective against this boss.
  • Molotovs and Oil Urns can be combined for a safe, effective strategy.
  • The Arcane weapon buff Empty Phantasm Shell is effective against this boss.
  • Using the Tiny Music Box during this fight will cause the Wet Nurse to side step.
  • Most of her attacks (save for the blade flurry) can be rolled under. Pay attention to which way her arms move when she swings them around.
  • She is particularly weak to bolt, an upgraded Tonitrus or another upgraded weapon with Bolt Paper can do massive damage to her.
  • She is extremely weak to Rapid Poison as well.

 

Attack Name Attack Description & Counter
Flying Lunge Dodge forward into the attack or evade to the left or right to avoid this attack.
Long Slashing Attack with all Blades The Wet Nurse slashes viciously with all blades. Evade away from this attack or position yourself behind the boss so that you can attack during this long animation.
Spinning Attack The boss spins from its left to its right. Evade into the boss towards the left side to avoid this very dangerous attack. If this attacks hits you will take massive damage.
Lunge Attack The boss uses all of her blades to to do lunge attack in a straight line in front of her. If you take your distance, the attack won't even hit you most of the time.
Blade Slam The boss slams all blades on the ground in front of her. Has a long windup, and is easy to get hits in if you roll behind her.
Arm Stretch Occurs while the arena is covered in fog. The Wet Nurse stretches her arms forward in an attempt to stab the player. While this attack covers a great distance and can be difficult to see, it's easily avoided by dodging to the side.
Nightmare Veil Blankets the area in darkness, drastically reducing visibility. Keep moving till it wears off.
Phase 2 Attack Description & Counter
Deathly Duo Used only while Nightmare Veil is in effect. Summons a clone that attacks from beside you at regular intervals; Dash counterclockwise along the edge of the arena and don't stop moving until the effect ends.

Lore Notes

  • Mergo's Wet Nurse bears a resemblance to the Amygdala's with its four pairs of long limbed arms, although its head shape is entirely different.
  • The nightmare slain is actually Mergo, or the nightmarish link to Mergo, for whom the wet nurse is only the guardian. The long pause between defeating the boss and the confirmation that the nightmare is in fact slain only happens after the baby's cries fade away and goes silent.
  • Mergō is the first person form of the latin verb mergere which can mean anything from "to submerge", "to overwhelm", "to drown", "to conceal". One may assume that Mergo submerges the player and various NPCs in The Nightmare.
  • Mergo continues to cry during the fight and there is a strange patch of light just past the crib.
  • She is the only Great One that uses weapons and the blades greatly resemble the Burial Blade. According to the Burial Blade's description the blade, the siderite blade "fell from the heavens". It may have been dropped or given by The Wet Nurse.
  • The Wet Nurse does not bleed. Instead, hitting her produces puffs of dust and a strange sound. The same thing happens when hitting ghostlike enemies like Silver Lady, Evil Labyrinth Spirit and Mad Ones. This suggests that The Wet Nurse is a disembodied spirit.
  • Her amulet, with its four gems, matches the rune Communion.

 

Notes & Trivia

  • It's possible for the clone to remain after the fog dissipates.
  • She has one of two One Third of the Umbilical Cord's in the game that don't require correct actions to be taken at set times. The other being in the Abandoned Workshop.
  • After Mergo's Wet Nurse dies, the lullaby stops and the baby starts crying. However, using the Tiny Music Box makes the baby laugh before it goes silent.
  • After defeating her you can also go back the direction you entered, and Queen Yharnam, who was previously sobbing, will bow her head in thanks and vanish.
  • Mergo's Wet Nurse, along with Moon Presence, are the only two bosses that give the message "Nightmare Slain" instead of the normal "Prey Slaughtered" (or the Japanese message "You Hunted"). However, it could also be argued that the "Nightmare Slain" message doesn't appear until Mergo's crying stops, implying that the Nightmare was Mergo. The DLC increases this number to three with the Orphan of Kos.
  • The battle is triggered by going near the baby stroller, so it's possible to circle around the whole arena without starting the fight, as long as you stay a certain distance away from the stroller.
  • This fight was bugged and seemingly incomplete in pre-release copies, having only one attack programmed. This is not the case in the proper releases. Restarting the console seems to help with that glitch.
  • If you kill Mergo's Wet Nurse while she finishes casting her fog, her dying animation plays but the fog and health bar stay. You have to wait until the fog disappears to see the "Nightmare Slain" screen.

    • Holy hell she's a tank, sat her for like 5 minutes just wacking her with the chikage, got down to like 10 vials even though I dodged 90% of her attacks lmao

        i didn't realize there was a pause after the fight. i waited around a bit and decided i needed to kill the baby so i attacked the crib (overturned at this point) and immediately got the "nightmare slain" message. thought that was kinda funny

          bloodborne nailed it with the weapons and the lore, but the bosses are terrible. Mergo is a good example, as there is little room to breath and this makes for a rng fight.

            Why cant i even attack mergo’s clone? I swung at it several times, but my attacks had no affect, and the clone just teleported behind me and one shot me

              A wet nurse is a person the breast feeds a baby. When I look at this thing there is one simple question that comes to mind. Where the hell are her tits.

              • Anonymous

                Why she always drops 72000 Blood Echoes? There is any lore reason or hidden meaning or it is only a random thing that happens?

                  I remember after defeating her for the first time, the long pause was making me panic and was prepared to use Bold hunter's mark until the "Nightmare Slain" appeared. Chills.

                    Can't believe this was the final boss. This was by far the easiest final boss in any fromsoftware game. Kinda disappointing to be honest.

                      After killing The Wet nurse, Viola's (Gascoigne's wife) body disappears from Tomb Of Oedon. Can someone add this to trivia or lore?

                          I mean yeah you can kill the clone in one hit but it instantly spawns another one, so what even is the point?

                          • on co-op I found a bug with the nightmare veil attack. Once it ends, her scythes are still glowing as if the mist was still there and the clone occasionally shows up. It's actually pretty obnoxious lmao

                              I just experienced a rare glitch that makes so her second phase never began. It went night only after I defeated her. Since this was my first play through I thought the boss was way too easy. Thank God I got lucky and had a glitch :)

                                I got her health bar to 0 and it didn't show that the battle ended for a hot sec. I thought there was going to be a second phase, she was much easier than I expected.

                                        When I stood next to the basket that supposedly contains Mergo after killing her Wet Nurse, I thought I heard a shush from a woman before the baby stopped crying. If someone can confirm this, it would be interesting to know if it is Queen Yharnam that soothes the child or maybe even the Doll, maybe as a nightmare mediator. If not then it is possible I consumed too much insight IRL and I am hearing things

                                          I jus smack her ass a lot and run and roll like a mad man when the purple fog happens... very haaaaarrrrd!!!

                                            If you run and dodge like a spastic during the mist you'll be totally fine. Just wait for the arms to appear then dodge accordingly, it's easier than going for hits, as you'll get ganked

                                            • I swear to GOD I'm 100% sure the Mergo's crying sound effect is the same found in the level 6 "Infiltrate the Manji Cult" of Tenchu. Tenchu came out in 1998 (more than 20 years ago!) so the audio designer is the same or he used the same file in the library. Awesome!

                                                    Attacking it with the transformed Chikage makes her take a massive damage burst after a few hits, like bleed or frenzy.

                                                                Does not have the same number of limbs as Amygdala--Amygdala has 9 limbs (7 arms, 2 legs), whereas Wet Nurse has 8 arms and maaaybe 2 legs, but with or without the legs, it does not add up to 9. Not that it matters much, as spidery creatures are a big trend in Bloodborne and obviously all share some connection, but most people miss that detail on Amygdala.

                                                                    • Anonymous

I know if you respawn after killing Moon Presence, you can avoid the credit roll and NG+ cycle even though MP is dead. I wonder if you would have to fight the Wet Nurse all over again, or if Mergo would just stay alive, or if Mergo would die upon respawning... Oh damn I gotta test this out now.

                                                                      • Anonymous

                                                                        I wonder if Mergo's Wet Nurse might have something to do with the "call to the bloodless" mentioned by the Befuddled Villager. I mean, the Wet Nurse IS kind of the one perpetuating the dream and the scourge, which is evidently the exact sort of curse the Villager wanted to place on the "blasphemous murderers..." And if there was one word to physically describe the Wet Nurse, I'd say "bloodless" is a pretty accurate contender.

                                                                        • Anonymous

                                                                          Honestly, I feel there's a strong connection between Mergo's Wet Nurse and Eileen The Crow. My reasoning behind this is simply due to them having similar qualities. One clue is that the wet nurse's attire and feathers are very much like Eileen's attire, the Crowfeather set, and it mentions "sky burial" (leading to where the wet nurse appears from i.e. the sky). Another clue would be the description of the Blade of Mercy, "forged with siderite, a rare mineral of the heavens," which is similar to the wet nurse's blades and Gherman's Burial Blade- as mentioned in the notes. One other thing that is a bit far-fetched is that out of most of the NPC's we never see Eileen's face, which could give the idea that she has no face, similar to the wet nurse. Now, this is simply just a theory and nothing is concrete.

                                                                          • Anonymous

                                                                            • It's just my impression or this boss fight is designed to be a cakewalk for a ranged build? I fought her as a physical quality build and found out she barely did anything at all while I was at long range. In fact, the fight was a constant getting closer, fishing the attack, dodging it, land some hits and rinse and repeat...the only difficult part, for me, was the dark mist part, actually....can someone whi played ranged build confirm this?

                                                                              • Anonymous

I guess that's a pretty common theme in Bloodborne, though. Willem was once Laurence's master, but Laurence rejected his warning; the Vicars are the successors to Laurence's establishment, yet they don't seem to follow his teachings, either. Rulers are constantly being superseded by their subjects, perhaps because their servants envy them and their closeness to Greatness.

                                                                                • Anonymous

But then it seemed to lock on / focus on something totally apart from me. It just kept nailing the wall, circling and slashing the opposite direction as me. Almost like it thought I was the baby? It's the same melody as Margo's lullaby..... Just really strange. Seemed very non aggressive after that, though it did do the clone. But even then, the clone attacked me while the actual nurse just faced the wall and stood there. I saved the video via PS.

                                                                                  • Anonymous

                                                                                    Funny enough this would make the Moon Presence almost look like a good entity that just wants the infection to be over.

In the second time I try I used beast pills and bold paper, I kill it in less than a minute (no shadow clones).

                                                                                          • Anonymous

                                                                                            So, Mergo is dead in the waking world, stillborn from Queen Yharnam. However, as seen with Micolash, whose mummified body we find in Advent Plaza, one can be dead in reality but alive in the dream. Being an Old One fetus, however, he still needs to be sustained by a mother, in this case a surrogate, a wet nurse. Now, given that once the wet nurse dies, Mergos cries fade away, we can conclude that the formless wet nurse was the only thing keeping him alive.

                                                                                            Divert for a second and consider Yharnam bowing to the Hunter after the fight; Mergo's constant crying suggests he was in pain or otherwise suffering, and the Queen is thanking you for putting him to rest.

                                                                                            Finally, let's consider the role of the Moon Presence in all this. We know it instituted the hunt, and that the hunt ends when Mergo is dead. But what stake could it have in euthanizing Mergo? Well, the Great Ones are not unsympathetic to humanity and the School of Mensis is directly responsible for the plague of beasts by summoning the Blood Moon via a crying Great One. So, it may be that having transcended the physical world, the Moon Presence was merely trying to clean up the mess made by The Brain of Mensis.

                                                                                            • Anonymous

                                                                                              • Anonymous

                                                                                                • Anonymous

Put rapid poison gems on your weapon and stock up on poison knives to throw at him. Remember when you phase and there's two of them that you don't need to dps them to get it over with, just focus on surviving, it will end eventually.

                                                                                                        • I managed to beat her with a tonitrus the first time with only 5 blood vials and no quicksilver bullets, just time your side steps perfectly and stay behind her at all times and spam your weapon and you should be fine.

(Also helps that both are the only ones to give the "Nightmare Slain" message upon being killed).

I wasted a full compliment because it is stated that they are effective. I also stacked all the fast poison I could onto my +10 Ludwig's (+9.6, +6.4, +9.6) and it didn't do a thing.
