Blood Rock

A 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 is an upgrade Item in Bloodborne.


Blood Rock Usage



  • The main game contains one Blood Rock 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.


Pthumeru Chalice Blood Rocks

  • Pthumeru Ihyll: Glyph: jrwffkyp. Just after Chamber of the Seal, before main area. In the first pre-area. Beware of fatty.
  • Pthumeru Ihyll Root Chalice (Cursed Fetid Rotten): zziz2qbx. Layer 2 (pre-area before the boss room).
  • Sinister Pthumeru Ihyll Root Chalice: Glyph: u6d8itwm.
  • Sinister Pthumeru Ihyll Root Chalice: Glyph: hdmg5dzw. Defeat the layer 3 boss. (Pthumerian Descendant) Also had highest tier "Eye" rune equipped.


Loran Chalice Blood Rocks

  • Rotted Lower Loran Chalice: Glyph 4292egu2, Layer 2 (In pre-area before second lantern). (I found this to be incorrect, it is in on Layer 1 in the pre-area between the Chamber of the Seal and Layer 1 lamps, in the sewer section in a sarcophagus protected by a madman)
  • Fetid Lower Loran Chalice: Glyph 7guktqyg, Layer 1 (In the side area before the boss room).
  • Lower Loran Chalice: Glyph 6rxwxu3e, Layer 1 (1st bonus door, does not require offerings).
  • Rotted Lower Loran Chalice: Glyph gysprnag, Layer 3 upon beating the Aborrant Beast Boss.
  • Sinister Lower Loran Root Chalice: Glyph v77hfp2e, Layer 1 pre-lamp. (Sinister offering)
  • Fetid Rotted Lower Loran Root Chalice: Glyph xf9deybn, Layer 1, side area before the boss room. 
  • Fetid Rotted Cursed Lower Loran Chalice: Glyph g5pkmkua, Layer 1 pre-lamp


Isz Chalice Blood Rocks

  • Isz Root Chalice Glyph rr4jfbys, layer 3. Located through the bonus room past the boss gate.
  • Isz Root Chalice: Glyph fsieuy9x, layer 3.
  • Isz Root Chalice: Glyph wbgypzky, layer 1. 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.
  • Isz Root Chalice: Glyph s626p982, layer 1. Fetid Rotted Cursed. In the bonus room past the boss gate. The chest room has a tomb prospector hunter, a brainsucker, and a horde of celestial children.
  • Isz Root Chalice: Glyph gftbrfx6, layer 3; 2 blood rocks. 1st : chest in a bonus room before the boss. 2nd : for killing the boss; the Pthumerian Elder.
  • Isz Root Chalice: Glyph xdsyzmp6, Layer 2.
  • Isz Root Chalice: Glyph h6panx99, layer 3 . Fetid Rotted Cursed. Pre-Lamp side area. 





  • 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.

      Loran Chalice Blood Rocks
      Rotted Lower Loran Chalice: Glyph 4292egu2, Layer 2 (In pre-area before second lantern). (I found this to be incorrect, it is in on Layer 1 in the pre-area between the Chamber of the Seal and Layer 1 lamps, in the sewer section in a sarcophagus protected by a madman)

      This is close, however the actual location is layer 1 pre-boss bonus room. The coffin protected by a madman (labrynth sage) is correct

        Isz root chalice dungeon no rites
        Blood rock in Layer one pre area, chest

        I advise completing the dungeon, tons of loot including: red jelly, tier 5 tomb mould, and ritual blood, lost threaded cane, bastard of loran, pearl slugs. Plus it has neat stuff like undead giant wandering bosses, chest placed jn front of each other and more

            A good tip for solo'ing most Depth 5 Chalice Dungeons around Blood Levels 100-120 ( Max out Vitality upto 50 for a solid 1500HP with your Hunter... Then make sure to Equip those 3 Runes & 1 Caryll Rune for a good Survivability specialy doing Depth 5's alone ). First equip Communion +4 Blood Vials for a total 24 Blood Vials with your hunter , 2nd Rune should always be the Great Lake Rune for that "+4% All Damage Eeduction" it might not seem alot , but this Rune does save you from getting 1 Shotted all the time... The Final 3rd Rune should be your personal prefference. ( Either go with Clock-Wise Meta for that 10% HP increase , or definitely go with the Lake Rune for an increased "+3% Physical Damage Reduction" with the Great Lake Rune you should have more than 300+ Physical Defense ( This could easily make out for being 1 shotted all the time , with a total of 24 Blood Vials or 25 Blood Vials , you could Solo any Depth 5 Chalice Dunegons specialy the Root Chalices Depth 5's ). The Caryll Rune i always go with Hunter Mark for that "Stamina Recovery Speed +UP" . Good luck Hoonting.

              There's also a good chance getting Blood Stone Chunks in any Bosses with Depth 5 Normal Chalices... Pthemura , Loran & Isz ( Blood Rocks can also be dropped by the Final Bosses of each normal Depth 5 Dungeons ). It's also depends in Luck sometimes you can get the Blood Rock by killing Celestial Emissary during the normal Isz Chalice Depth 5 , even before Ebrietas Final Boss ( The Depth 5 normal dungeons are pretty tough aswell , i'm level 132 yet i can still get 2 Shotted ). Goodluck , in Lower Loran Root Chalice the final boss could also drop Blood Rock ( After getting those Rocks you will get instead Great One's Wisdom ). And also 1st or 2nd Layer Bosses will drop some Chunks , and sometimes with possible High Luck/Discovery you could get Blood Rocks from even the Boss before the Last Layer.... Try finishing up the normal game playthrough , then go grind in Chalices Depth 4 & 5 for more Chunks & Blood Rocks before hitting NG+ for a good start up.... Plus Chalices do also give many Insight fighting Bosses . ( This could also help buying another Blood Rock from the Insight Messenger Bath for 60 Insight after the 1st time getting it when killing Mergo's Wet Nurse ). I also saw most Depth 4 & 5 Chalices to provide you with Madman's Knowledges aside from the ones you get out of the Dungeons like in the Story Playthrough Bosses & Such... Goodluck

                You can pull the lever, drop the brain of Mensis down, go down an elevator into the abyss and then make contact with it there too.

                            You absolutely can get the rune after killing the brain. It's more difficult because you no longer know exactly where you have to stand, but you can use notes left on the ground by other players to get a good indication of where to stand. Do the "make contact" gesture like you're supposed to in the right spot and you'll get the rune even after the brain is dead and gone.

                                Maybe put an asterisk or something when giving IMPORTANT Info? Or put the IMPORTANT part UNDER the description which would prevent one obtaining whatever (in this case THE MOON RUNE!!!) Grr.

                                    So I just got 2 bloodrocks for ailing loran chalice type I read here it’s only suppose to be one? Maybe I’m just lucky as rest of the glyphs are now giving mad ones wisdom.

                                      I scoured all three Bloodborne wikis as well as Reddit for glyphs and the details about those glyphs. Then I checked every single one of them to see if they were still active, some of them twice just to make sure they were really dead. This is what I came up with; the fastest paths to all the Runes and Lost / Uncanny weapons as well as all the gem farming glyphs that are still active. Enjoy!
