Micolash, Host of the Nightmare (悪夢の主ミコラーシュ Akumu no shu Mikorāshu lit. "Micolash, Lord 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.
  • This boss is not optional, as defeating him is the only way to cause the bridge to rise and progress to the next area.


  • 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; the Cannon is recommended 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 always 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 minimize 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 threshold, 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.

Strategy 9 (Aggro and fight through the gate)

If you have a gun which can hit through walls (such as the blunderbuss) and a decent-range melee weapon such as the axe or threaded cane, you can cheese the second half of this fight.

After you’ve got Micolash down to half health, he will teleport away from you and go to the second part of the arena. He will run away from you again and will lead you to the second fight room. This room has a gate which drops down after he enters but before you can enter.

Now you want to kill all the puppet men in this room and equip a gun like the blunderbuss which can hit him through the gate. Stand right up against the gate and shoot the blunderbuss at him. This will aggro him and he'll start running towards the gate to attack you. You can then use a long weapon like the hunters axe (in its two handed form) or threaded cane (in whip form) to hit him through the wall. He might try to cast a magic attack or try to punch you through the wall, but he didn't do this in my playthrough. The puppets may also respawn after some time, but if your melee weapon is powerful enough he should be dead by this point.

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.
  • What Micolash says upon death is more accurately translated as, “Will I wake up?  Will I forget everything?”  This implies that he has no idea that his body in the waking world died when he entered the nightmare and that his death in the nightmare  is actually permanent.

      Micolash normally : some lore stuff.

      anyway, I'm still explaining Bloodborne lore to my dad.

        There is a Wandering Madness that drops a couple bloodstone chunks and a higher-level Moon rune at the bottom of a spiral staircase as you chase Micolash into the second phase of the fight (where you turn right to go up the stairs after him - if you go left that's where it is). It's guarded by some crossbow attendants and a Chief Attendant. I went and got it after the fight was over

          I suck at dodging spells, but his poise is so low I didn't even have to. Enjoyable fight overall and he is a very cool character!

            Most easy cheese boss in the game. Didn’t even have to use this site to figure out the bow blade strategy. Also a first phase addition to the version of that strategy. If you go up the first stair case to the middle platform (killing any mannequins that spawn on the way) and slightly enter the hallway you can see him at the end of, enough to prevent the mannequin behind you from respawning but not enough to trigger Micolash to run away. You can cheese the first phase by Bow shooting him. He will despawn after every shot but will respawn right back in front of you. Also stand about dead center in the hallway, this becomes important later. Rinse and repeat until about 45% and he will try to run to the first room, by trying to run through you if you stood right in the middle of the hallway. Switch to blade mode or your alt weapon and beat him down until he despawns to start phase 2.

                Worse boss in the whole souls franchise, took me a good half hour of listening to his inane banter on loop before finding the way into his locked room

                  if youre complaining about A Call Beyond, keep in mind he doesnt use it if you are close to him, just stick to him or trap him in a corner and hes dead as hell

                    He reminds me of a water balloon, but rather than water, he's full of lore. but just like water balloons, they pop easy if you stick 'em with something sharp. (that frailty being of course, his boss battle)

                      **** this dude. Any boss where being able to viably damage them comes down to RNG and then gets the ability to instakill you is automatically a bad boss, let alone when that boss is from ****ing soulsborne

                          Getting him inside the dead end has nothing to do with insight but with what direction you drop into his room.

                            Hate the fight, hate his stupid voice and hate tje stupid puppets and mannequins. No redeeming qualities to this fight at all if you have no idea what you are doing and is a wonderful example of From Soft logic: Oh it's a mage character...They have a weapon but nah LET HIM SPAM NOTHING BUT SPELLS LIKE A *****! 0/10 would not fight again and I often avoid him if possible

                                Beast roar makes this fight very easy. I'm suprised it's not on the strategies. Beast roar will knock him down, so you can get a few hits while he's on the ground, as soon as he get's up, use beast roar, hit him again, rince and repeat.

                                  I think my micolash was glitched because on the second phase he did not want to go in the last room instead he ran around till I killed him
                                  All in all that was the first timei ever won tag so I'll take it

                                    This fight was incredibly goofy and irritating. I found that in the transition to the last phase, he would not jump into the mirror unless I approached him. He wasted 2 hours of my time so I shot him in the face with every bullet and moltav that I had.
