Description [ ]

This hidden research facility of the Healing Church , is dedicated to the knowledge and methods of attaining the transcendence of humanity through the creation of Kin .

From what is gathered by its denizens - the many Clocktower Patients that did not become wildly violent as a result of going mad; including Saint Adeline - and Simon himself, who has guided players thus far, it appears that the many doctors experimented with the minds of these patients, imbibing them with water somehow.

It is implied that the experiments that took place in this hall would culminate with the creation of the Celestial Emissary .

Lamps in the Area [ ]

• Lumenwood Garden
• Astral Clocktower

Connections [ ]

• Surgery Altar

Ground Floor [ ]

The ground floor is composed mostly of the Lamp, the poisonous pit in the center of the rotating staircase contraption, the door to the Balcony, and the shortcut to other floors via the elevator in Saint Adeline 's room. One can find a passive Clocktower Patient looking for its "eyes" here.

When the rotating staircase has been raised, a number of Bound Clocktower Patients will appear on the Ground Floor along with two more items, one of these items being a Lethal Damp Blood Gem.

• Blood Stone Chunk x4
• Blue Elixir x1

(These items below can only be accessed once the rotating staircase has been raised)

• Lethal Damp Blood Gem x1
• Kin Coldblood (10) x1

1st Floor Balcony [ ]

This area can only be accessed via the Balcony Key . This area seems to share a strong semblance to the Lumenflower Gardens . The 1st Floor Balcony houses a number of Clocktower Patients who can attack using Arcane spells, it also houses the Blacksky Eye .

One can break through the large window in the area much like in a similar way how one breaks through the large window in the Lumenflower Gardens . Through this window, one will end up being on the upper layer of the Surgery Altar . On this upper layer, one can find a Wandering Nightmare and a Pulsing Damp Blood Gem. Lastly, the player needs to jump over a small gap and open a chest for an item .

• Blacksky Eye x1
• Pulsing Damp Blood Gem x1

Laboratory Floor 2/3 [ ]

The third floor will have a single Church Servant on it and a naked Clocktower Patient . On this floor one can find a passive Clocktower Patient begging for Lady Maria. Inside the third Laboratory room will be a trio of Wheelchair Huntsman , two wielding Pistols while one wields a Rosmarinus . One can access the first (where Adeline can be found), second and fourth (if the player has opened the short cut) Laboratory rooms from the third room. The third room also serves as a get between to get to the different floors faster.

The second floor can only be accessed from the third Laboratory room. The second floor will have about 3 Feral Clocktower Patients . Also, it's where the player can find the rest of the Decorative Old Hunter Set . One more thing the player can find on the second floor is another passive Clocktower Patient on a Balcony digging through some dirt.

• Madman's Knowledge x1
• Beast Blood Pellet x6
• Decorative Old Hunter Garb
• Decorative Old Hunter Trousers
• Frenzied Coldblood (9) x1

Patient Room Floor 2 [ ]

On this floor, one will encounter a surprisingly large number of Clocktower Patients. In the first room one will encounter a large number of Clocktower Patients, these Patients will roam in and out of the room. On the top layer of the room, there will be about 2 Clocktower Patients throwing Bottles of corrosive liquid at the player.

The second room is hidden behind some medical equipment. In this room is a number of passive Clocktower Patients begging for help. Both rooms must be gone through to access the fourth floor.

• Blood Vial x2
• Sedative x3

Patient Room Floor 4 [ ]

The main part of this floor can only be accessed through the first room. In the first room, the player will first encounter a Giant Clocktower Patient attacking seemly at random. When the player exits the first room they will witness a Gatling Gun Wheelchair Huntsman gunning down some Clocktower Patients.

In the second room the player will be ambushed by an Infected Clocktower Patient there is also one normal Clocktower Patient just roaming around in the middle of the room. Also from the second room, the player can get to the top layer of the first room, from there, the player can find a Dirty Damp Blood Gem.

• Blood Vial x5
• Antidote x2
• Quicksilver Bullets x3
• Dirty Damp Blood gem (5) x1

Patient Room/Laboratory Floor 5 [ ]

This floor is important as the very first door will have the elevator shortcut that connects to the ground floor, and it's the only way to get up to the Rafters. The player can encounter the Gatling Gun Wheelchair Huntsman that was gunning down the Clocktower Patients from before on this floor. This is the only floor apart from the first floor that the player can access both the Laboratory Room and the Patient Room without needing to use the rotating staircase.

The Laboratory Room just serves as an elevator shortcut, While Patient Room is a lot more interesting. Outside the Patient Room is a number of Headless Clock tower patients who will wander aimlessly around and aren't hostile to the player. Inside the Patient Room is a number of Clock Tower Patients who are just Heads. Unlike the Headless Patients outside these ones are hostile and will attack the player. Also inside the Room is the Enlarged Head . Another thing to note is beware when leaving the room because a Head will attempt to ambush the player when leaving the room.

• Blue Elixir x4
• Enlarged Head x1

Laboratory Floor 4 and Patient Room Floor 3 [ ]

These two Floors can mostly be accessed via going through a secret path from the elevator that leads to Laboratory Floor 5 to Laboratory Floor 3. Laboratory Floor 4 serves no purpose at first. But when the rotating staircase has been raised it serves as a get between to get to Patient Room Floor 3 and to get to the Loch Shield .

When going from Laboratory Floor 4 to Patient Room Floor 3 via the rotating staircase one can access the Loch Shield . Just go down the furthest staircase and one will find a Bound Clocktower Patient and an item, this item being the Loch Shield .

Patient Room Floor 3 holds a small number of Clocktower Patients, one of these Patient being a Bottle Thrower. After getting through the Patients the player will find 4 Quicksilver Bullets and more importantly the Underground Cell Key . But be warned when attempting to get the Underground Cell Key an Infected Clocktower Patient will attack from behind.

• Loch Shield x1
• Quicksilver Bullets x4
• Underground Cell Key x1

Rafters [ ]

The topmost part of the Research Hall and the most important part of it. To get to the Rafters the player must first get pass the Giant Clocktower Patient who is guarding the ladder to the Rafters.

The Rafters unlike most of the Research Hall don't contain any hostile Clocktower Patients but it dose contains few animal type beasts, these animal beasts being Labyrinth Rats and Carrion Crows . This floor is important as it holds the device that can raise the rotating staircase and it holds one of the quest important items for Adeline‘s questline. Also on this floor, the player can find two passive Clocktower patients, The first one is banging his head against a wall while the other one is on a higher layer. The other passive Clocktower patient is important for Adeline ’s questline.

Beware when leaving the Rafters when the device that controls the rotating staircase has been triggered. As when the player reaches the middle part of the rotating staircase a trio of naked Clocktower Patients will run up and attack the player. Also when leaving the player will notice a chest being guarded by a trio of Carrion Crows, this chest will have a Finestrike Damp Blood Gem.

• Great One's Wisdom x1
• Blood Stone Chunk x1

(The item below can only be accessed via the rotating staircase and only when the rotating staircase has been raised)

• Finestrike Damp Blood Gem (5) x1
• Brador, Church Assassin
• Saint Adeline
• Simon the Harrowed
• Yamamura the Wanderer
• Clocktower Patient (non-hostile ones)

Enemies [ ]

• Carrion Crow
• Church Servant
• Clocktower Patient
• Labyrinth Rat
• Wheelchair Huntsman

NPC Hunters [ ]

• Church Pick -wielding Yahar'gul Hunter .
• Female Black Church Hunter who wields Ludwig's Holy Blade .
• Female White Church Hunter who wields a Threaded Cane .
• Male Black Church Hunter who wields a Threaded Cane and Repeating Pistol .
• Living Failures
• Lady Maria of the Astral Clocktower

Summons [ ]

• It is likely also the tallest, likely rivaled only by the Healing Church Workshop .
• Said traps can only be found adjacent to large bookcases.
• There is a wolf figure under the bed in the altar which resembles the wolf figure under the bed the hunter see in the opening cinematic. This suggests that, not only the Hunter , but many people experience the "mere bad dream" during blood transfusion . But, no Messengers statue can be found in the Research Hall, which suggests they don't appear to many and only those who the Messengers choose would become Hunters of the dream. "Ah! You found yourself a Hunter"- The Doll .

From Ludwig's boss room, take the stairs up and exit through the door on the left side to reach a corridor. Enter the first room on the left for a Frenzied Coldblood . There are Church Servants and Wheelchair Hunters in this corridor as well. Keep heading down the corridor and pop into the rooms on the right, one of which has the Fist of Gratia . Head up the stairs to reach a ward of some description. There is a Great One's Wisdom in one of the beds. There are two tough NPC's up here who are a bit challenging. Separate the two as much as you can and kill the darker coloured NPC first before engaging the other one. You will get Madman's Knowledge and Quicksilver Bullets x10 . Behind the stairs in a dark room are a few Rats guarding a Blood Stone Chunk .

Approach the statue at the end and insert the Eye Pendant to create an elevator. Light the Lantern here then take the lift back down. Let the lift go back up but don't ride it, instead wait for a second lift to arrive and grab Laurence's Skull . Pull the lever to lower the lift and get on this one to reach the very bottom for the Church Cannon . Return to the Lantern at the very top.

As soon as you enter the Research Hall proper, kill the Scurrying Beast on your immediate left for its materials. A second one is on the opposite side of the room on the stairs by the water so kill that one as well. Grab the Blue Elixir x2 in the pool but don't hang around in the pool. There is also a new enemy here.

--Clocktower Patient-- These guys are all over the Research Hall and there are many variations of them. While in general they are easy to defeat, some of them are tough like the Giant Patients can be quite painful. Drops: Blood Vial*, Quicksilver Bullets*, Madman's Knowledge*, Blood Gems*, Coldblood* , Blue Elixir* * Certain Variants will drop different items

Take the stairs up and deal with the Patients here. When you have two paths available to you, take the left path to the balcony here. There is a pressure plate on the floor on the immediate right on the way to the item so avoid that if you can before you grab the Madman's Knowledge . If you do accidentally step on the trap, some projectiles come out of the bookcase so be careful of that. There are several traps on these balconies so keep an eye on them.

Watch the trap here and deal with the Church Servant. There is a Patient you can talk to here but nothing really of interest. Open the door on this balcony and deal with the three Wheelchair Hunters in this room. Grab the Beast Blood Pellet x6 at the back then pull the lever to create a shortcut. Take the lift down and open the door to return to the bottom floor. There is an NPC tied to a chair you can talk to.

--NOTE-- This NPC is Adeline who has a little questline attached to her. Step 1: Talking to her will tell you to grab Brain Fluid which are dropped from the blob sacs in the Research Hall. Step 2: Give her two Brain Fluids, reload and you will get the Balcony Key. She can also offer you her Blood Vial as well. Step 3: After opening the Balcony Door, she turns into a Blob Sac and asks you to find a final Brain Fluid for here. Kill her and gab the Fluid then give it to here. You will get the Milkweed Rune before she dies for good.

Talk to her and then return up the elevator. In the room with the Wheelchair Hunters, take the ladder down at the back. Kill any Patients here and grab the Decorative Old Hunter Set . Open the door and head left, kill the Patient here and grab the Frenzied Coldblood . There is another Patient who can talk to out the door on the right side but again, nothing of value. The stairs here leads nowhere for now so return to the room with the Wheelchair Hunters.

Go back down the stairs and take the other stairs now up to the balcony opposite the one we were on. Kill the Patients up here as there are many of them in the upcoming room. Grab the Blood Vial x2 then open the door on the far left of the balcony and enter this medical room. There are some Patients here you can kill if you want but head up the ladder. There is a Giant Patient up here so be careful taking this guy on. Grab the Blood Vial x5 from the corpse in the room after killing it. Head up the stairs and open the door to reach another balcony higher up. Before exploring this, head back and there should be a ladder in the room with the enemy we killed. There are tons of Patients down here and the reward is not worth it so feel free to skip this whole room if need be but your reward is Sedative x3 under the stairs. Return to the balcony now.

Grab the Antidote x2 on the balcony before ascending the stairs here where more Patients await. Enter the room on the other end of this balcony and kill the Patients in here before grabbing Quicksilver Bullets x3 . Take the side door here and grab the Dirty Damp Blood Gem on this narrow balcony before returning to the large balcony.

There is a Wheelchair Hunter who will be shooting at you as you climb these stairs. Make sure you sprint on by to avoid it. Head down the stairs in the next area and get your revenge on the Hunter. Walk around the entire floor, killing the Patients and avoiding the floor trap before grabbing the Blue Elixir x4 at the end. Open the door here but watch out for the Patient Head Sacs that are in this room. Grab the Blue Elixir and the Enlarged Head for yourself before leaving.

Head back to the stairs we took to get down here and open the door. Take the lift here and hop out the lift early on the right side to reach a slightly lower balcony. There is a tough Hunter down the stairs here. You can try knocking him off but if not, play it safe until he is dead. Grab the Sedative x5 from him. There is a Blob Sac here that can't really die but kill it once for the Brain Fluid . Drop down the lift and immediately exit into the room with all the Wheelchair Hunters again before the lift goes back up. Return to Adeline and give her the Brain Fluid. She will give you the Blood of Adeline . You may need to use a Blood Vial before you claim this one. Return to the Dream. Finish upgrading the Cannon as well as repairing and checking gems. Reach Level 86 with 43 Vitality . Return to the Research Hall.

Take the lifts up to reach the top faster. Reach the top of the stairs here and then climb the stairs further to the very top. There is a Giant Patient up here so kill it then climb the ladder. Follow the rafters along here and grab the Great One's Wisdom but watch out for any Rats or Crows that can knock you off here. At the very back is a Blood Stone Chunk . There is another Patient you can talk to but nothing again of interest. Pull the lever in the centre of the rafters to raise the stairs, chase the Crow off the edge but don’t follow it as you can’t return to this area. This crow has the Guidance Caryll Rune so you will need to grab this on a return up . On the opposite end where the Crow was is another Blob Sac with a second Brain Fluid .

Take the ladder down now and go down the stairs, then take the stairs down to the left. Kill the Crows and open the chest for a Finestrike Damp Blood Gem . Now take the right stairs down. Several Patients may run up to get you here so deal with them efficiently. Circle around this walkway. You should run past the Wheelchair Hunter so you know you are on the right path. Enter the room at the end here and take the lift down, remembering to jump off halfway through to reach the lower section. Head down then back up again and kill the Patients up here. Grab the Quicksilver Bullets x4 on the corpse then grab the Underground Cell Key but watch out for the Patient hiding in the corner.

Head down the stairs, then down again and grab the Loch Shield on the ledge. Now is a good time to grab the Caryll Rune from the Crow at the top. Drop down to the bottom floor. Grab the Lethal Damp Blood Gem and the Kin Coldblood in the water that has newly appeared. Return to the Dream now and do your standard checks while you are here. Reach Level 87 with 44 Vitality and then return to the Ludwig's arena. Head into the long dark corridor and open the locked door on the left. You may want to clear the enemies first before doing this if they get involved. Kill the NPC in here for his Khaki Set . There is another locked door on the right side that leads to a Frenzied Coldblood . In the room on the very far left is a Hunter. They can be tough but you can hit them through the wall or use the door to kill him easily. You will get the Church Pick from them.

Take the lift back up now to the Research Hall and Simon should now be here. Talk to him if you want but its optional to talk to him here. Return to Adeline and give her the second Brain Fluid for the Balcony Key . You may have to quit and reload a few times to trigger this event. With the key, you can open the door at the back on the ground floor to take you outside. Drop down then drop down again to reach a flower garden and several Patients. Grab the Kin Coldblood on the opposite side. Jump down into the garden and kill the Patients here. These ones can fire an arcane blast at you which can be annoying. Using a Blue Elixir can help you fight only one or two at a time making it easier for you. Grab the Blacksky Eye on the chair here then attack the window at the back, very reminiscent of how we reached Ebrietas. Kill the Scurrying Beast on the left for its materials then head right, jump over the gap and grab the Pulsing Damp Blood Gem in the chest. Drop down and take the lift back up to the Research Hall. Return to the Dream and reach Level 88 with 45 Vitality and do your normal checkups while you are here.

Return to Adeline and keep reloading until she becomes a Blob Sac in the corner. Talk to her, then kill her to grab the third Brain Fluid. Wait for her to revive and offer her the Brain Fluid. She will give you the Milkweed Caryll Rune . Take the lift up and out to the balcony. Climb the stairs here and you can now open the giant door. Beyond this door lies a boss fight.

--BOSS: Living Failures-- Swings and Slams The boss can do a variety of swing attacks usually a singular or double swing. They have quite a long range on this so watch out for that. The boss can also slam its hands down for some pretty big damage. Homing Orb The boss can charge up an orb of Arcane magic that follows you for a while before exploding so keep your distance until they expire. Headslam The boss can slam its head onto you. Fairly fast of an attack but one of the least threatening. Arcane Missile The boss can shoot several energy blasts at you. Easily avoidable if you use the giant tree in the middle. Meteor The boss will stop and raise its arms in the air. After a while, the screen goes dark and several meteors rain from the sky, dealing heavy damage. Getting a backstab into the visceral can protect you from this attack as well as get extra damage in or use the tree to hide. Strategy A similar looking boss to the Emissaries, the Living Failures are the easiest boss in the DLC by a huge margin. There are also several of them in this fight that share one health pool. Find an isolated enemy and hack away until it dies, moving to the next one when you can. The boss has some hard hitting frontal attacks but has no protection from behind so circle around and attack them in the back, perhaps charge attacking for a backstab can work for you as well. The boss is fairly standard as they are fairly slow and not that aggressive but if your damage is limited, they can spawn faster then you can kill them and they can become a threat if left for too long. Yamamura, the NPC we killed in the locked cell earlier can be summoned just outside the boss room and he makes this fight a breeze. He can weaken the boss a little bit allowing you to kill one enemy in one combo for an easier time. The giant tree can help for two attacks in this fight, arguably the most dangerous ones. Some of the Failures use a magic attack. You can hide behind the tree to avoid this attack with no issue at all but just watch out for any Failures sneaking up on you. The second attack is their ultimate attack, the meteors. Although this attack hurts, you can easily avoid it by hiding behind the left side of the tree, assuming the way you came in is behind you. If you want to be a little aggressive, instead of using the tree, getting a visceral attack on them can give you immunity when the meteors arrive and can help you take out one or two of them before the attack finishes.

For defeating the boss, you will get the Astral Clocktower Key and the Living Failures Trophy . Light the Lantern and open the door with the key you just got. Return to the Dream for any checks you need to do then return and enter the new building for another boss fight.

--BOSS: Lady Maria of the Astral Clocktower-- Phase 1 Basic Sword Attacks Lady Maria has many combos and attacks with her swords. They can be a little difficult to pinpoint the difference between certain combos but they are not that damaging in comparison to her other attacks. Cross Attack Maria crosses her swords across her chest and dashes forward. This is usually done at the end of a combo or just as a unique attack on its own. It also pushes her forward slightly. Overhead Attack She will put both her swords above her head and slam down. This is a fairly strong attack so avoid this one if you can. Phase 2 Blood Slashes All of her attacks will now have a blood streak that extends the range and can hit you you for extra damage if you get caught by it. Charged Stab Will charge a stab attack for a while before stabbing really fast unleashing a blood line in front of her. This comes out very fast so you need to try and dodge at the right time to avoid it. Charged Slam She can also charge her slam which leaves a little blood AoE afterwards. Keep your distance or get behind to avoid this one. Jump Attack Does a little spin attack before launching up in the air then landing back down. Run directly underneath her where she jumped to avoid the damage from this attack. Phase 3 Fire Slashes All of her attacks now fire damage on top of the blood attacks. This increases the range a little once again as well as damage. Cross Parry She will do a cross attack that she can visceral attack you afterwards if you are hit by her. Strategy Lady Maria is one of, if not the best, most fun boss in the game but can be tricky to get by her several phases and long combos. She also is really quick being able to dash away after a combo to avoid a lot of your attacks so keeping up with her is half the battle. The main strategy to deal with her early phase is to always dash to the right, her left and start flailing until she backs up or unleashes a combo of her own. In fact, this strategy will carry you through the entire fight as it really saves you so much avoiding her attacks. Cut the distance, bait out her attacks and repeat until you can trigger her next phase. When she stabs herself and blood comes out, she has a few extra things to deal with. She will now have blood attacks on her weapons which extends the range of her attacks, dealing more damage and leaving you with less time to heal from the threat. She can do a jump attack but this is easy enough to avoid if you go straight underneath her when she jumped. Almost all of her attacks remain the same except with extra blood extensions on it. At round the last 25% HP, she enters her third phase. Make sure you stay away from her when she switches to another phase to avoid the damage. There isn't much change throughout the fight on how to take her down. The extra extensions just makes keeping your distance worse so staying up close to her is the way to go. Be careful when you need to heal as she can punish you if you let her. The Whirligig Saw can still stun her no matter what the phase so use that to your advantage when you can. Another thing to note is your positioning. With Maria, you want to be ideally as close as you can to her to avoid her long reaching attacks. If you cannot close the distance, then get far away from her as you can until an opportunity to close the distance presents itself. You want to avoid, at all costs, a medium distance as this puts you in perfect reach of her combo attacks and in the second and third stages, this can easily punish you if you get caught in them.

For killing her, you will get the Lady Maria of the Astral Clocktower Trophy . Grab the Celestial Dial on the floor after she is dead. Start in front of her chair and use the Dial to turn the tower allowing you to exit through the tower. Head on through the tower and into the Fishing Hamlet, the final area of the DLC. Grab the Lead Elixir and a Madman's Knowledge , ignore the NPC, then light the Lantern at the end. Return to the Dream for your standard visit. Reach Level 89 with 46 Vitality . You can buy Maria's set if you wish from the fountain with some Insight. Next up will be the Fishing Hamlet.

Bloodborne - Research Hall, Patient Room 2, Patient Room 4, spiral staircase

How to survive the Research Hall in Bloodborne's DLC.

This article explains how to survive the Research Hall in Bloodborne: The New Hunters.

If you're interested in more advice, our complete Bloodborne walkthrough and for the DLC our The Old Hunters guide and walkthrough can help.

To begin the next perilous leg of your journey, climb the staircase to the right of the lamp and enter the majestic Research Hall. At the top, look left and locate the Scurrying Beast near the wall - kill it before it disappears to receive a Blood Stone Chunk.

Next, turn your attention to the pool in the centre of the chamber. There's a brain-headed, non-hostile creature splashing around in the water nearby. As you draw near, it will begin to mourn its missing eyes. Descend the steps and grab the Blue Elixir from the corpse by the central column in the pool. Note that the water is poisonous so move in and out quickly.

To the rear of the chamber, opposite the entrance, you'll spot another Scurrying Beast carrying Blood Stone Chunks. You'll also find a door marked '1st Floor Balcony'. However, the door is currently locked - so, for now, return to the Research Hall entrance.

Approach and climb the spiral staircase

From here, take a right and approach the huge spiral staircase. You'll likely aggro the hostile brain creature above as you near, so be ready to fight. These poor souls are, for the most part, weak and easily dispatched. Occasionally, however, they'll become enraged, and their repeated flailing attacks can do serious damage - so be prepared to dodge clear.

When it's safe to proceed, locate the doorway on the right at the foot of the spiral staircase, signposted 'Laboratory Floor 1'. This door only opens from other side so, for now, begin climbing the spiral steps. Once you reach the first small landing, you'll encounter more hostile brain creatures, with another batch likely spilling down the steps to the right.

Once you've cleared the area, you'll note that there are two staircase leading up from the first landing - one to the left and one to the right. The left-hand staircase winds to the landing above, while the right-hand steps lead to the balcony running around the room.

Kill the enemies inside Patient Room 2

Take the right-hand staircase first and, once you reach the top, pass through the doorway marked 'Patient Room 2' directly ahead. Inside, you'll find a ton of brain creatures wandering around, all of whom will immediately launch an attack. Most annoying of these are the acid-jar-tossing enemies situated overhead - their projectiles can cause significant injury if you're hit. Deal with the creatures on the ground floor then take out the wave of enemies that come pouring down the stairs. Finally, eliminate the hostiles stationed on the upper level of the room.

When the area is clear, take the Sedatives from the corpse in the corner on the ground floor then climb the large stone steps. Pass through the doorway directly ahead and scale the ladder to the left. At the top, you'll encounter a brain creature wielding a medical drip. He's taller and stronger than his brethren, and can pack a real punch thanks to his fast, frenzied pummelling. He's pretty easy to dodge around however, so shouldn't cause you much trouble.

When it's safe to proceed, grab the Blood Vials from the corpse in the far left-hand corner and note the exits on either side of the room. The right-hand route leads to another ladder and a room full of non-hostile patients - but we'll be paying them a visit later.

For now, climb the steps to the left. Take a right at the top, ascend the next flight of steps and pass through the door at the end. You'll emerge on the upper balcony - turn right and follow it along, grabbing that Antidote from the corpse on the left.

As you near the spiral staircase ahead, a wheelchair huntsmen will open fire on a group of brain creatures somewhere above. Be wary here: there's a doorway to the right (marked 'Patient Room 4') and the screams will likely draw the creatures beyond toward their comrades.

Before resuming your journey up the spiral staircase, investigate the room on the right, immediately dealing with any remaining hostiles. Grab the Quicksilver Bullets at the back of the room then ascend the stone steps to the right. You'll emerge overlooking the area where you fought the drip-wielding creature earlier. Take the Dirty Damp Blood Gem (5) from the corpse to the right then about face, descend the steps, and leave the room through the doorway to the left.

MOSCOW (AP) — Assailants burst into a large concert hall in Moscow on Friday and sprayed the crowd with gunfire, killing over 60 people, injuring more than 100 and setting fire to the venue in a brazen attack just days after President Vladimir Putin cemented his grip on power in a highly orchestrated electoral landslide.

The Islamic State group claimed responsibility for the attack in a statement posted on affiliated channels on social media. A U.S. intelligence official told The Associated Press that U.S. intelligence agencies had learned the group’s branch in Afghanistan was planning an attack in Moscow and shared the information with Russian officials.

It wasn’t immediately clear what happened to the attackers after the raid, which state investigators were investigating as terrorism.

The attack, which left the concert hall in flames with a collapsing roof, was the deadliest in Russia in years and came as the country’s war in Ukraine dragged into a third year. Moscow Mayor Sergei Sobyanin called the raid a “huge tragedy.”

The Kremlin said Putin was informed minutes after the assailants burst into Crocus City Hall, a large music venue on Moscow’s western edge that can accommodate 6,200 people.

The attack took place as crowds gathered for a performance by the Russian rock band Picnic. The Investigative Committee, the top state criminal investigation agency, reported early Saturday that more than 60 people were killed. Health authorities released a list of 145 injured — 115 of them hospitalized, including five children.

Some Russian news reports suggested more victims could have been trapped by the blaze that erupted after the assailants threw explosives.

Video showed the building on fire, with a huge cloud of smoke rising through the night sky. The street was lit up by the blinking blue lights of dozens of firetrucks, ambulances and other emergency vehicles, as fire helicopters buzzed overhead to dump water on the blaze that took hours to contain.

The prosecutor’s office said several men in combat fatigues entered the concert hall and fired on concertgoers.

Dave Primov, who was in the hall during the attack, described panic and chaos when the attack began.

“There were volleys of gunfire,” Primov told the AP. “We all got up and tried to move toward the aisles. People began to panic, started to run and collided with each other. Some fell down and others trampled on them.”

Videos posted by Russian media and on messaging app channels showed men toting assault rifles shooting screaming people at point-blank range. One video showed a man in the auditorium saying the assailants had set it on fire, as gunshots rang out incessantly.

Guards at the concert hall didn’t have guns, and some could have been killed at the start of the attack, Russian media reported. Some Russian news outlets suggested the assailants fled before special forces and riot police arrived. Reports said police patrols were looking for several vehicles the attackers could have used to escape.

In a statement posted by its Aamaq news agency, the Islamic State group said it attacked a large gathering of “Christians” in Krasnogorsk on Moscow’s outskirts, killing and wounding hundreds. It was not immediately possible to verify the authenticity of the claim.

However, U.S. intelligence officials confirmed the claim by the Islamic State group’s branch based in Afghanistan that it was responsible for the Moscow attack, a U.S. official told the AP.

The official said U.S. intelligence agencies had gathered information in recent weeks that the IS branch was planning an attack in Moscow. He said U.S. officials privately shared the intelligence earlier this month with Russian officials. The official was briefed on the matter but was not authorized to publicly discuss the intelligence information and spoke to the AP on condition of anonymity.

Noting that the IS statement cast its claim as an attack targeting Christians, Aymenn Jawad al-Tamimi, an expert on the terrorist group, said it appeared to reflect the group’s strategy of “striking wherever they can as part of a global ‘fight the infidels and apostates everywhere.’”

In October 2015, a bomb planted by IS downed a Russian passenger plane over Sinai, killing all 224 people on board, most of them Russian vacation-goers returning from Egypt. The group, which operates mainly in Syria and Iraq but also in Afghanistan and Africa, also has claimed several attacks in Russia’s volatile Caucasus and other regions in the past years. It recruited fighters from Russia and other parts of former Soviet Union.

On March 7, Russia’s top security agency said it thwarted an attack on a synagogue in Moscow by an Islamic State cell, killing several of its members in the Kaluga region near the Russian capital. A few days earlier, Russian authorities said six alleged IS members were killed in a shootout in Ingushetia in Russia’s Caucasus region.

On Friday, statements of outrage, shock and support for those affected by the concert call attack streamed in from around the world.

Some commentators on Russian social media questioned how authorities, who relentlessly surveil and pressure Kremlin critics, failed to identify the threat and prevent the attack.

Russian officials said security was tightened at Moscow’s airports, railway stations and the capital’s sprawling subway system. Moscow’s mayor canceled all mass gatherings, and theaters and museums shut for the weekend. Other Russian regions also tightened security.

The Kremlin didn’t immediately blame anyone for the attack, but some Russian lawmakers were quick to accuse Ukraine and called for ramping up strikes. Hours before the attack, the Russian military l aunched a sweeping barrage on Ukraine’s power system, crippling the country’s biggest hydroelectric plant and other energy facilities and leaving more than a million people without electricity.

Dmitry Medvedev, deputy head of Russia’s Security Council, said that if Ukraine involvement was proven, all those involved “must be tracked down and killed without mercy, including officials of the state that committed such outrage.”

Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, denied Ukraine involvement.

“Ukraine has never resorted to the use of terrorist methods,” he posted on X. “Everything in this war will be decided only on the battlefield.”

John Kirby, spokesman for the White House National Security Council, said he couldn’t yet speak about the details but “the images are just horrible. And just hard to watch.”

Friday’s attack followed a statement earlier this month by the U.S. Embassy in Moscow that urged Americans to avoid crowded places in view of “imminent” plans by extremists to target large gatherings in the Russian capital, including concerts. The warning was repeated by several other Western embassies.

National Security Council spokesperson Adrienne Watson said Friday the U.S. government had information about a planned attack in Moscow, prompting the State Department advisory to Americans. The U.S. government shared the information with Russian authorities in accordance with its longstanding “duty to warn” policy, Watson said.

Putin, who extended his grip on Russia for another six years in this week’s presidential vote after a sweeping crackdown on dissent, denounced the Western warnings as an attempt to intimidate Russians. “All that resembles open blackmail and an attempt to frighten and destabilize our society,” he said earlier this week.

Russia was shaken by a series of deadly terror attacks in the early 2000s during the fighting with separatists in the Russian province of Chechnya.

In October 2002, Chechen militants took about 800 people hostage at a Moscow theater. Two days later, Russian special forces stormed the building and 129 hostages and 41 Chechen fighters died, most from effects of narcotic gas Russian forces use to subdue the attackers.

In September 2004, about 30 Chechen militants seized a school in Beslan in southern Russia taking hundreds of hostages. The siege ended in a bloodbath two days later and more than 330 people, about half of them children, were killed.
