Blood Rock is an upgrade Item in Bloodborne.

blood_rock.jpgA large solid chunk that forms in coldblood.

After death, a substance in the blood hardens, and that which does not crystalize is called a blood stone.

This is no mere chunk, it is nearly a boulder.

Few blood stones of such size have ever been discovered, even considering the combined experience of all the hunters.


Blood Rock Usage



  • Only one blood rock can be obtained from the main game per NG cycle. It is found near Nightmare of Mensis: Middle Loft.
  • A total of three others can also found in sarcophagus chests depth 5 root chalice dungeons (One in each type; Pthumeru, Loran, and Isz)
  • There is also a chance of one dropping from the final boss of any depth 5 root chalice dungeon.
  • With the addition of The Old Hunters, there is one more Blood Rock in the Fishing Hamlet. Down the elevator leading to the boss, go into the large room opposite to the tunnel guarded by 2 Winter Lanterns and at the other side (through many snail women) you'll find the Blood Rock. The way to the Blood Rock from Lighthouse Hut lamp is shown .
  • After Patch 1.09 you can buy Blood Rocks from the Insight Shop in Hunter's Dream after beating Mergo's Wet Nurse. One Blood Rock costs 60 Insight.




How to get blood rock in Nightmare of Mensis:


1. Without Killing the Brain of Mensis

To get to this item easily and painlessly it is recommended that you return to the dream and spend all your insight. After that apply the Deep Sea rune for frenzy res, and wear your best frenzy res armor. Make sure you also have plenty of sedatives. Then spawn at the Mensis: Middle Loft lantern after killing Micolash, Host of the Nightmare, head outside, up 2 flights of stairs, and get into the bird cage elevator. During descent, there is a window you can jump into from the elevator (see video below).
From this point, run across the bridge with the 3 Winter Lanterns using the skull-rocks to avoid Frenzy. Run past the spiders, descend the stairs (careful in this room there is a hole in the floor which you can fall through earlier than wanted,) pull the lever on the balcony, this will trigger a cut-scene showing the Brain of Mensis drop into the abyss. After the cut-scene, turn around and drop down into a hole on your right. After dropping down the hole, run outside, collect all the items, drop down into the collapsed tower on the bridge (avoiding the bottomless pit in the center of the room) and there is a body holding the item.
Note: The Brain of Mensis is the creature causing Frenzy in the entire Nightmare of Mensis area, so the 'Killing the Brain of Mensis' option below is high-risk and should be avoided. Pulling the lever in this option allows players to get Blood Rock with no risk of Frenzy aside from the Winter Lanterns, and drops the Brain of Mensis into a abyssal pit where it can be killed without inducing frenzy. This also allows players to get the Tier 3 Moon rune.

2. Killing the Brain of Mensis

After killing Micolash, Host of the Nightmare, use the Iron Door Key to open the door located on the left side of the wall at the beginning of the boss fight. The door will open onto a bridge with numerous Insight items, and lead to a collapsed structure. Drop down into the collapsed structure to find the Brain of Mensis and a body holding the item.
IMPORTANT: Killing the Brain of Mensis this way will prevent one from obtaining the Tier 3 Moon Rune from her via the 'Make Contact' gesture in the abyss. You will, however, still get the Living String required for the Great Pthumeru Ihyll Chalice.

By making contact and getting the Moon rune then killing the brain, you can get both the rune and the Living String.

Blood Rocks in Chalice Dungeons

This item is also available in high-level Chalice Dungeons such as Isz Root Chalice or Lower Loran Root Chalice. It is a low drop-rate, so make sure you have high Discovery, which can be increased either by adding points to the Arcane stat or using certain runes.

The community has shared a few glyphs that contain blood rocks. Big thank you's to those who created and shared these chalices!

  • 1 Blood Rock available per Chalice type: Pthumeru, Loran and Isz (NOT Hintertomb)
  • Great One's Wisdom will replace Blood Rocks, (just like runes), if already obtained in that Chalice type.
  • This limitation does not reset upon entering NG+(+).
  • Rumored to reset upon some trigger, or through PvP victories, but none confirmed.
  • Blood Rocks can also be obtained by defeating Depth 5 Chalice Dungeon bosses.

  • Blood Rocks found in Chalice Dungeons seem to have a reset trigger (has yet to be confirmed, possibly after a certain time has passed?). It has been claimed you can get a second from Chalice Dungeons if someone shares the Glyph of a dungeon containing it but this is yet to be confirmed.

      Someone told me there was 5 BloodRocks in each play through.
      I just got the one from Mensis, and the one from Hunter's Nightmare. (those are 2)
      I got one from defeating Ebrietas in Level 3 Root Isz Chalice (making 3)
      And just got another three from the glyphs in this webpage.

      I'm absolutely sure that I got 6 blood rocks this time. Seems like you can farm Blood Rocks from Ebrietas in Level 3 Isz Root Chalice. Can't tell the drop rate, though.

        I got one from Ebrietas in a non-root Isz Chalice (the one she drops after beating her in the main game the first time). I've also seen videos of people getting Rocks from Loran Darkbeast in Lower Loran, Layer 3.

        • Mother Brain Location #205 Jul 2016 08:44  

          If anyone is wondering where Mother Brain falls to, take the non-cage elevator from the base lamp, then move past the creepy children and fat guy. There'll be a pretty obvious elevator there, taking you down to the (completely dark) floor. There you will find Mother Brain and you can kill it, it won't fight back. It drops a Living String (with interesting lore attached, it claims Mother Brain is a Great One)

          • Steps for Moon Rune05 Jul 2016 08:44  

            1. Obtain "Make Contact" gesture <br/>2.Get on the elevator with the busted cage and jump through the window <br/>3. Pull Lever on Brain (doesn't kill it) <br/>4.Head to room with sink holes (with the 2 armored fat guys and little men) <br/>5.There now should be a elevator there in the middle. Enter it and it will take you below ground. <br/>6.Do not kill the Brain, walk up to it and use "Make Contact" gesture. <br/>7.Drops Living String when killed. <br/> <br/>May need Mensis Cage. Other attire NOT required.

            • Re-rolling Dungeons05 Jul 2016 08:44  

              To my understanding: Blood Rocks have a chance to appear inside treasure coffins. Does resetting/rerolling a dungeon (pull the chalice off, spend materials to reuse same chalice, different seed) also give another chance to have another shot at a Blood Rock in a coffin/chest?

              • Having difficulty making Rotted Lower Loran Dungeon05 Jul 2016 08:44  

                How do you actually create the Rotted Lower Loran Chalice dungeon? How do you get the chalice in the first place? I have the Lower Loran Chalice already, but it won't let me create a rotted version to allow me to create another chalice dungeon to get the Blood Rock. Can anyone help? That is the last Blood Rock I can get this run through, and I want to get all of the in each playthrough.

                • miss information05 Jul 2016 08:44  

                  Please mention that in the rotted lower loran also rerequires a fetit offering. Because after I made the rotted offering is till did not meet the requirements

                  • BLOOD ROCK GLYPH05 Jul 2016 08:44  

                    Great phtumeru ihyll root, with rotten and foetid. The rock is in the bonus area in a gold chest, the area is through a door just before the layer 2 boss fight and you dont find the rock instantly, its a bit of a trek. Glyph is 9v7p9gd2. PS. to be able to access a chalice like this, or any other, i think you have to complete it first on your own before you can search for a glyph of the chalice. That might be why you're having trouble :)

                      wbgypzky - Sinister Isz Root<br /><br/>The blood rock is in the very first forked path, before the second lantern. A very straightforward path, there's a regular zombie, some spiders and a brainsucker on the way to it.<br /><br/>(I would edit it right into the page, but this wiki engine is a piece of *****.)

                      • "To the left of the start of the Micolash Bossfight"05 Jul 2016 08:44  

                        This could not be any more unclear or misleading. What is the "start" of the fight? Which stage of the "fight" are we referring to?

                        • 05.06.201605 Jul 2016 08:44  

                          Isz Root Chalice:Glyph wbgypzky worked for me, <br/>however the fsieuy9x Layer 3 one only contained a Great Wisdom :( <br/>(Assuming its the branch-off way right before the Layer 3 Lamp) <br/>Rest of the mentioned ones aren't found anymore or I don't meet the requirements.
