Lower Pthumeru Chalice


A chalice that breaks a labyrinth seal.

But only a Root Chalice changes the shape of the old labyrinth when used in a ritual.

The old labyrinth was carved out by the Pthumerians, superhuman beings that are said to have unlocked the wisdom of the eldritch Truth."


Lower Pthumeru Chalice is a Chalice Item in Bloodborne. You can create this chalice dungeon by combining the materials listed below at one of the Tomb Altars in Hunter's Dream. This dungeon never changes Bosses, design, or loot.



Lower Pthumeru Chalice Information





Merciless Watcher (Layer 1)

Undead Giant, Club/Chain/Sickle version (Layer 2)

Rom, the Vacuous Spider (Layer 3)

Bloodletting Beast (Layer 4)



  • This is the first of the Pthumeru Chalices to have a fourth level.
  • Each level has a hidden wall but their locations varies.
  • There is a hidden wall in Layer 1's first off-shoot leading to a chest with a Sage's Wrist. - neomerdien neomerdien-
  • There is a hidden wall in Layer 2 that leads to a treasure room. - neomerdien neomerdien-
  • There is a hidden wall in Layer 3 that leads to a treasure room. - neomerdien neomerdien-
  • There is a hidden wall in Layer 4 (which leads to a Bath Messenger vendor that sells the Sinister Lower Pthumeru Root Chalice as well as uncanny and lost versions of some weapons you have). This wall is through the door left of the lamp, up the ladder and in the room with the tree, hounds, spiders and Keeper of the old Lords (just behind it on the right wall). It will look different than the rest of the room. If messengers not found on Layer 4, then its on either Layer 1, 2 or 3 behind a hidden wall. - neomerdien neomerdien- NOTE: you will find every DLC weapon you have as uncanny and lost in this bath messangers
  • If the player dies to Rom at the same time that Rom is killed Layer 4 will be unavailable to the player. (confirmed) *possibly patched? Just happened to me, and I was able to continue to Layer 4 with no problem.
  • After completing this dungeon Ritual Blood (2) and Tomb Mold (2) can be bought from the Messengers in Hunter's Dream

      You will only have 3 layers if you haven't killed Mergo's Wet Nurse. The door to the 4th layer will appear after it is dead.

        Ugh, why is Rom here. That fight is a boring and infuriating slog. I'd rather drink a glass of vinegar than be reminded of that*****ty boss.

          If you have trouble with bloodletting beast just call 1 or 2 old hunter they will distract the beast so much that you won't even take much dmg and kill it easily

            Layer One is an excellent place to farm souls once you're somewhere around Levels 75-90, I always run through the side path on the right at the very beginning (getting somewhere between 3500-5000 Blood Echoes), then I go past the yellow lamps to the main part of the first layer. Run through this as quickly as possible (Go Up ladder and straight to the left. Kill that guy for like 1555 souls, then kill the CHime Maiden and the tall undead guy at the bottom of the final room where the boss switch is). I run through the entire Layer 1 area in maybe 2-3 minutes, and it nets me about 12k-13k souls, especially if I get extra blood echoes from using the run that boosts Visceral Attacks. This is a good place to level up or farm souls to stock up on items. It can be a bit tricky at times because of the damn spiders that the Chime Maiden conjures, but once you get a rhythm going, it's very rewarding. I've leveled up considerably doing this

              I found the bath messenger, some reason he's not selling ANY weapons? I have all the regular ones pre-dlc...

                The first time I went through here, I completely missed the 4th layer, and assumed that Rom was the last boss. It took me way too long to realize that there was a 4th.

                  Sure would be nice to have actual directions to these illusory walls that weren't so fucking vague and images that weren't busted. But hey, the half-assed, sloppy, lazy writing and complete lack of any fact checking on this wiki is just par for the fucking course around here.

                    Is anyone able to lend a hand for Rom on layer 3? I can summon Prospector Olek, but he focuses ads instead of Rom.

                      Do I have to do this whole damn dungeon again because layer 4 won’t appear??? I didn’t even know there was a 4th one until I started looking for more ritual blood.

                              I managed to defeat Rom in the Lower Pthumeru Chalice with a combination of Lake runes for arcane defense, some blood gems for fire damage, and a combination of oil urn, flamethrower and molotovs
