Micolash, Host of the Nightmare is a Boss in Bloodborne.

Micolash, Host of the Nightmare Information

"Ahhh Kos... or some say Kosm.  Do you hear our prayers?" 


  • In Nightmare of Mensis, taking a left from the lantern, follow the path to the castle and progress through until you reach a long bridge and two rising Ethereal Walkers, after which you will find the boss room.
  • After defeating this boss, the long bridge will rise and the Mergo's Loft Middle lantern will spawn.



  • Blood Echoes: NG (48400), NG+ (242000), NG++(266200), NG+3 (302500), NG+6 (484,000), NG+8 (605,000)
  • Mensis Cage
  • You gain 2 Insight for finding the boss, and 2 Insight for beating him.


Combat Information

  • You will be fighting him in a library with steps going up and down. There is tons of mist on the ground making enemies harder to see. Overall he is not aggressive boss, but has one dangerous AoE spell, tentacle arms, and Ethereal Walkers  who help him during the first part of the fight.
  • Initially you need to find and follow him to a dead end room where you can beat on him until he is half health.
  • He will teleport away after half health. Head up the stairs, past a few of the crossbow Mannequins. You will arrive in another area that looks just like the first area. He will be there, but will soon run into a dead end room, dropping a gate that prevents you from entering. Head up the stairs here and you will find a drop down where you can drop into that dead end room.
  • When you engage the boss for the second time he will be much more aggressive, using Augur of Ebrietas, fists (very weak), and A Call Beyond, that is very difficult to dodge and might one shot you. The secret here is to never let him cast A Call Beyond, because if he does then you are really only counting on luck to survive it. If you stand really close to him (literally touching him), he will never use that spell, resorting instead to his fists and tentacles, which allows you to simply stun him to death, while occasionally strafing to dodge his tentacles. If you get too far away and he does manage to start the spell, shoot him immediately, if you catch him early enough in the animation it will stagger him out of the casting
  • Backstabs (charged R2 to the back) can be performed when he does the tentacle attack if you have a fast enough weapon. This is a reliable way to deal considerable damage (and even heal yourself if you have the right runes), particularly during the first half of the fight.
  • Depending on your Insight count, Micolash may teleport through different mirrors after teleporting at half health. After hitting Micolash several times along the chase from mirror to mirror, he will eventually run into the dead end room as usual.
  • In his second location, Micolash gains the ability to use A Call Beyond to summon numerous arcane missiles and unleash them upon the hunter (also used by hostile hunter in Bergynwerth). If it hits multiple times it will kill anyone from full health (it has no trouble 1 shotting a hunter with 50 vitality and equipped with full choir set). He will sometimes spam this ability, using it again as soon as he completes channeling the first attack. Using the Old Hunter Bone will help somewhat, but other than that there is no real counter when he does this, since unlike the Augur of Ebrietas, this attack cannot be interrupted and the missiles will fire even if Micolash is staggered in the middle of this channel animation.
  • If you have a high enough Arcane to use Beast Roar, hit him with as many attacks as you can. Then, once your Stamina bar is almost empty, cast Beast Roar. It will knock him down and give you time to either heal or get your stamina back to repeat the process. This will ensure that he will never get a chance to cast his AoE again.


Attack Name Attack Description & Counter
Augur of Ebrietas Summons mid-range tentacle strike from palm. Can avoid just by walking. Long recovery time means this attack can consistently be punished with a back-stab. In the first phase, this will be the only attack Micolash uses.
Punch Micolash punches 2 or 3 times in succession, dealing low damage.
A Call Beyond Summons numerous arcane missiles to attack the hunter. Very dangerous, capable of one-shotting hunters from full health. Evade straight at Micolash to avoid this attack consistently. Dodging from side to side is risky.
Note that this is unlike the barrage attack that Ebrietas uses; the missiles will fire simultaneously rather than in three waves, and will carpet the entire area with only some missiles homing toward their target.


Strategy 1 (Co Op)

The Chase: Before he runs into the first room, have someone stand in front of the door (preventing him from entering). The other person is free to chase and hit him without him retaliating. After he disappears and goes into the next area, have someone stand in between the next dead end room and the middle of the room where he spawns after hitting him (This prevents him again from leading you into the final room to which there is no exit until you beat him. Allowing the other person to chase and hit him without him trying hit back). The person blocking the way is also able to get a hit in now and then; I'd suggest the Cannon because of its range and damage, plus buffed by the Bone Marrow Ash makes it work very well.

Strategy 2 (Killing him in Phase 1)

You can skip his second phase by killing him before he reaches the second room. For that, get him down to 50% in the first room. He will disappear. Go up the stairs and find him. Chase him till he jumps down from a ledge. DON'T follow him. Instead go down the stairs and attack him. Instead of going to a dead end he will run down the stairs. Follow him and get a few hits - he will disappear. Now go back to the place where he jumps down. He will wait along the way. When he sees you, he will run to the ledge. You can go back to the room where he lands. Now you're standing in the room to which he jumps - he is standing on the balcony. Run underneath him - he will jump; when he lands, get a few strikes. He will disappear and spawn on the way to the 2nd floor. Make him jump from the ledge again. With each jump you'll be able to land 1-2 hits and eventually you'll kill him without dealing with the second phase.

Strategy 3 (Cannon)

Do the first phase of the fight normally. Then, when he teleports, follow him until you reach the top of the room where he drops. Don't drop after him. Instead, switch to your cannon, press up to get +5 QS bullets and fire at him. Repeat until you're completely out of bullets. Don't forget to heal at some point. He should now be pretty low on health and you should be able to get him with a plunge attack. Alternatively, you can use any other kind of ranged attack, like Poison Knives, or you can increase the effectiveness of your firearms with Bone Marrow Ash.

Strategy 4 (Poison Knife)

For the first half of the fight deal with the skeletons quickly and then circle around Micolash hitting him with L2 attacks using Ludwig's in greatsword mode. If you just continuously walk around him while locked on and just out of sword reach, he will miss. When he runs away up to the point where you have to jump down through a square hole to fight him again - as for Strategy 3, any ranged strategy will probably work. Poison Knives are very effective. Two in quick succession will poison him. You won't see any damage counter but he will start running back and forth and his life bar will decrease until it wears off, at which point he will stand still again. It takes about 3 or 4 rounds of poison to kill him.

Strategy 5 (Melee)

Follow Micolash around for the first half of the fight right up until he enters the room where you will fight him. There are several paths from here, when you enter there will be two floating enemies dispatch them from a distance and aways keep an eye on Micolash because he uses a tentacle attack (Augur of Ebrietas) or you can lure Micolash out into the small corridor before the room, here he won't often attack so you can safely finish this stage. For the most part the first stage is easy because he only has the tentacle attack, but once he gets to around 50% health he relocates to a different part of library; follow him again until he has locked himself in the room. From this point on things will get a lot harder. First of all look around the maze for the drop in location. When you drop, start the fight with a plunging attack (I fought him with a +8 Ludwig's Holy Blade while using the highest arcane resistance gear I had, along with Fire Paper and Bolt Paper ). If you fail this he will usually use A Call Beyond which can one shot you, so be careful. For the rest of this fight you want to be super offensive. His melee attacks deal little damage and his tentacle attack is easy to dodge; there is no consistent way to dodge A Call Beyond, but he can easily be staggered while using this attack.

Strategy 6 (Aggressive Melee)

If you happen to be using weapons that don't stagger enemies (such as the Tonitrus) then the second half of this fight is nominally more difficult as you cannot stop Micolash from casting A Call Beyond if he gets into it.

Before you head to the boss room, head to the Hunter's Dream and make sure to equip the highest level Anti-Clockwise Metamorphosis run you happen to have. This will grant a higher maximum stamina which will be invaluable in this fight. Head to the fight and do the first half as directed above. In the second half, get him into his final room, then prepare yourself. Before you drop into the room, make sure you're at full health, then use a Bone Marrow Ash to buff your gun and a Beast Blood Pellet to increase your damage output. Peer over the ledge and lock onto him, then fall into the room and do a roll as you land. Not only will this minimise the amount of damage you take from the fall but it means you'll be ready to fight immediately.

Chances are Micolash will land a couple of punches on you, don't worry about this, instead get aggressive and combo him as much as possible. When you've got a small sliver of stamina left, dodge to the side and let him use the tentacle attack. Before he turns back to you, fire off a couple of shots from your gun. You won't do too much damage to him but you'll keep him from moving away to cast A Call Beyond. He should step back, so catch up to him, rinse and repeat. If you can get him pressed up against a wall, even better. The whole trick to surviving the second portion of the fight is to make sure that he doesn't cast A Call Beyond, so stay close to him, use regain to keep yourself alive (even if he hits you with the tentacle attack) and he'll go down quickly.

Strategy 7 (Blacksky Eye)

If you have enough arcane to use the Blacksky Eye, and enough insight to cause Micolash to jump through the mirrors, you can kill the boss before he gets to any of the "fighting rooms".

When you first cross the nightmare fog, Micolash will always be standing in the same place to start out with (up the stairs to the right, then down the hallway to the left). Normally, he will start to run when you get close enough to him, but with the Blacksky eye, you can stand far enough away from him to hit him with the spell, but not so close that he starts to run away. When nearing the 50% health threshhold, Micolash may attempt to run for his first fight room, but can easily be interrupted and cut down, as you would be standing between him and his room.

For his second phase, you will need to chase Micolash until he starts jumping through mirrors, then go to where you would normally drop down on him, only to have him run into his second fight room and close the door behind him. Instead of dropping down, simply stand on the ledge and continue to use the Blacksky Eye to whittle his health away. Each hit with the eye will cause him to vanish, then reappear in the mirror behind him.

This method is very reliable and easy to utilize, mostly because you don't have to worry about his use of A Call Beyond.

Strategy 8 (Bowblade)

If you have the Bowblade and plenty of ammo/blood vials, you can cheese this fight.

Progress the fight as usual and after you've gotten his health down to 50%, and he disappears, head upwards and pursue him until he runs into the first mirror. Now head to the right onto the balcony, and into the small room with a hole in the floor. Drop through but take a second to look around. You should see two skeleton puppets/mannequins yet to wake, and down the corridor Micolash is waiting in front of another mirror.

Walk forward slowly and kill the two mannequins that will wake. Be careful not to move too far down the corridor and trigger Micolash's running away.

Once the mannequins are dead, get your bowblade out, and walk slowly down the corridor until you can just lock onto Micolash. Once you can, use R2 to fire a powered shot at him. Micolash will be knocked backwards into the mirror, and come rolling forward out of it once again, only to stand still in the same spot.

Repeatedly damage him using R2, using blood bullets if you need to, and re-killing the mannequins as they wake up (still being careful not to trigger Micolash running), and he'll be dead in no time.

Notes & Trivia

  • The body found after defeating The One Reborn (Advent Plaza at end of Yahar'gul) wears a Mensis Cage just like that of Micolash.  It is also the portal by which the Hunter enters the Lecture Hall 2nd Floor which leads to Nightmare of Mensis.  Given that Micolash is the "Host of the Nightmare", it is likely that this corpse is his actual body in the waking world.

      If anyone's having trouble with the fight and doesn't want to cheese it, the Choir set has great Arcane Resistance, and can bring down the damage he deals quite significantly, and an additional 22% Arcane resist can be acquired with a full compliment of Arcane Lake Runes (the 5% and 7% are both found in areas before the Nightmare of Mensis, so even a 12% reduction is possible without entering the Isz Root Chalice dungeon). It helped me in NG+ where he always seemed to get 1 A Call Beyond off on me, and it allowed me to survive when it happened.

      • 09 Mar 2017 22:53  

        I wonder if maybe he's not just using his fists, but if he's also got the Kos Parasite to help him... It seems his, uh, karate chops deal a significant amount of arcane damage. What a nut.

        • 06 Feb 2017 11:04  

          Don't know if it was a bug or glitch, but i killed him VERY easily. All you need is Bone Marrow Ash (I was using the Repeating Pistol).If you have enough Insight, after tje first phase (which is really easy) he will use mirrors to move around. There is one mirror he gets out from that you can access from the floor above. Position there when he gets to that room and DO NOT jump. Use the Bone Marrow Ashe and shoot him. He will take pretty high damage and disappear. However, he will appear from the same mirror, so just repeat the process. I ran out of bullets (was low at the tima) so he lived with one HP. I followed him to the second phase room and finished him off with one hit. Again, the fact he keeps appearing from the same mirror may be a bug/glitch. Anyway, good luck!

          • 19 Jan 2017 02:15  

            I hate him, but he is really easily cheesed with poison knives or blacksky eye (with a decent arcane stat and emergency quicksilver bullets). I always cheese him as I can't fight a boss confidently that can spam a call beyond over and over if he gets the slightest chance... I mean can he at least have a 5 second cooldown on that attack, please?!

            • 18 Jan 2017 05:33  

              He backs into a wall in his second phase and I can't do *****. This is almost a really good boss but he's cheap! Arcane does and UNFAIR amount of damage for how well it tracks, and whoever wrote Fists (extremely weak) can ***** off. He hits almost as hard as spiders.

              • 16 Jan 2017 16:04  

                Haha God damn, drop from floor above, the second I get in range(while falling) starts a call from beyond - land - dead right away.

                Can't help but laugh at these moments.

                • 11 Jan 2017 09:58  

                  Curious. I just beat him recently and had the same experience! He never entered this "second phase" in my game. He just kept running away and all I had to do was chase him and hit him on the way until he finally died...
                  Now, my guess is that it has something to do with insight as suggested above? I had 50+ insight at the time, so maybe that's where he starts to "never enter" second phase? Can somebody confirm?

                  • 31 Dec 2016 21:32  

                    I just beat him and he didn't even go into his second phase. I don't know if it was me or a glitch but what I did was instead of falling after him where he falls by the mirror portal thing I went down the stairs and chased him more. He never went into the second room where the gate falls.

                    • 22 Nov 2016 00:55  

                      strategy 4 doesnt work, I'm amused how this page isn't refreshed after so long! he just disappears after 1 shot, and comes back again, resetting any of the negative buffs he had!

                        What i did was spamming the gatling gun with adding the power of poison knives for fast and extra damage, however i fell down when he had like 14% health left (i got careless) and he started to chase me while spamming his 1hit kill attack.<br/>Also he dropped 310000 souls for me and I'm NG+

                          Well, I've killed him pretty easy with simon's bowblade. After I've got him to 50% I just chased him, but didn't let him lock in room. Instead I'd jumped to said place and hit with charged arrow. Before I was bloody frustrated in this phase (I literally can't parry to save my life). But he started to teleport... and jump right throw mirror in front of me. Every single time after being hit.

                            You can glitch this boss.<br/>i was in coop an he was in a corner, he attacked me and glitchet into the wall. After that he had 1 hp left.<br/>Shot him in the second phase. One shot that was it.

                            • Hardest boss in the game23 Aug 2016 18:15  

                              That call beyond is a one hit kill, I am in ng+5 and he still is hard, every other boss I can do in one or two tries, this guy takes 10. My advice for the second phase use all stamina to r1 spam, then spam him with blunder buss until you can regain stamina this will kill him or weaken him greatly<br/>

                                yes I agree this is a gread dialogue but most likely the most crucal line that was looked over in the article is Micolash stating "Awooooooooo, Aaaaaaaaaa"

                                • Another way to cheese the fight.15 Aug 2016 22:52  

                                  This strategy would require a decent, thought not necessarily maxed, arcane and bloodtinge, but if his second phase is really giving you trouble there is an easy, risk free way to skip it. Eventually after he teleports, you will chase him to an area where he jumps off a ledge and stands in the center of a room below, begging for a plunging attack. Most of the time, a plunging attack will miss and he'll just run away. When you reach this point, DO NOT DROP DOWN AFTER HIM. You can just stand on the ledge above him and using blood bullets, you can finish him off with executioner's gloves, an evelyn, molotovs, poison knives, whatever. His arcane resistance is extremly high, so it will take a while, but he won't move, try to dodge, or fight back in any way, and there are no mobs that will aggro you from that point.

                                    Used Tonitrus in first phase, and kept him down with augur of ebrietas, second phase ludwigs longsword with fire enchantment and augur again to keep him down after he cast his own or tried to cast his aoe spell. Smooth kill

                                      In phase two follow him to the mirrors, if is gonna enter the big squere room DON´T FOLLOW HIM, go all way upstairs, look for the room you can drop down, there will be a ethereal puppet outside, drop down, and the will be outside the room confused, use a long range weapon (Beast cutter or the Hunter´s cane) and hit him once, <br/><br/>if you get too close he will run, but if you hit him with the long range weapon or a pistol he will reappear in the mirror behind him, giving you chance for another hit, rinse and repeat, just beware the puppets behind you. If he runs away, chase him to the mirrors again and drop into the room, he will be outside again waiting for you, if he is not, look for him, chase and repeat
