Living String

Special material used in a Holy Chalice ritual.

The immense brain that Mensis retrieved from the nightmare was indeed lined with eyes on the inside, but they were of an evil sort, and the brain itself was terrible rotten.

But even still, it was a legitimate Great One, and left a relic. A living relic, at that, which is a precious thing indeed.

Living String is a consumable material Item in Bloodborne.


Living String Usage



  • In Nightmare of Mensis, after defeating Micolash, Host of the Nightmare and using the lever to drop the Mother (Frenzy) Brain down, it is obtainable by accessing a green cage elevator in the black mannequin enemy area and then slaying the non-aggressive Mother Brain. Upon arriving in the dark area, head immediately northwest after exiting the elevator and it should be there. Listen for the sounds of its breathing.
  • Can be purchased in the Hunter's Dream for 10 Insight. The trigger for this item to appear is most likely killing the Mother Brain mentioned above. (Can confirm the Yharnam Stone is NOT required to buy the string and Make Contact gesture need not be done) (I killed her in my first play through but was never given the option to buy the living string. My assumption is that the trigger to buy it is first obtaining the string.)



  • Used to open the Great Pthumeru Ihyll Chalice Dungeon where Yharnam, Pthumerian Queen is located.
  • you can also get the moon +30% blood echoes rune by doing the make contact gesture for 40-50 seconds in front of the non-aggressive Mother Brain before killing it.
  • There seems to be a bug where killing the Mother Brain with a cooperator can cause you to not get the Living String. The bug seems to be caused by the cooperator landing the final attack, reloading the area and killing the Mother Brain again will get you the Living String.

      You can buy them in the insight shop ONLY after you've killed the Brain, it wasn't available to me after getting Moon from making contact. I could buy them only after I went back and killed the poor thing.

        Holy ****ing ****, I just want to be done with the awful chalice dungeons, but I end up having to farm materials for almost every single one - as if defeating defiled watchdog and amygdala wasn't a skillcheck enough, now I have to farm even more ****

        I understand that we all do this for the platinum and that it's optional, but did it really need a shitty grind for materials?

          This item is a progress lock, basically. You have to continue forward with the main game in order to continue with chalice dungeons at a certain point.

          • Is there another way to get the living string? Because I honestly don't want to kill the Brain of Mensis. It just looks so sad and helpless, lying in the dark.... I know it's terrible and evil and all, but there's a certain reverence about it that I don't want to disturb.

              Is there another way to get a living string? Does anyone know? Because honestly, I don't want to kill the Brain of Mensis. It just looks so pathetic and sad, lying in the blackness... like, I know it's evil and terrible and all, but I still feel like there's a certain reverence about it that should not be violated.

                There has never been living string in my insight store, I pulled the lever on mother brain several days ago and still didn't have it available. I looked up how to get it, found this wiki, double checked that I have never seen this item in my insight store, then left to go get it. Came back, and it's here in the store. I can 100% confirm that's what makes it appear. I don't know what qualifies making me a credible person and don't know if you guys wanna trust some random person but yeah I just did that and it's true. So there you go.

                • You can purchase this item BEFORE obtaining the Yharnam Stone, someone please change the entry. This item is purchasable from the insight merchants after having obtained the only one in game from the Mother Frenzy Brain, testing exactly what conditions are required to unlock each material.

                      In order to reach Yharnam the Queen (Yharnam Stone) you have to kill The Mother Brain (Living String). What's the purpose ?
