Bloodborne Micolash Boss Guide

The battle against Micolash is unique in that you have to continually chase after him, and he's assisted by a bevy of skeletons and even a couple Tiny Gents. When the boss battle first begins, you need to find Micolash. Head up the stairs and continue moving higher and looping around the top floor until you spot him. As soon as you see him he'll run into one of the rooms. Follow him there to find two skeletons in the room with him.

How to Defeat Micolash, Host of the Nightmare in Bloodborne

In this first room, you should focus on the skeletons before turning your attention toward Micolash. The skeletons go down fairly easy, but if you don't have an overly powerful weapon, you may have to attack the skeletons multiple times. They fall down after a few swings and will get back up shortly after so you can continue the assault.

Once the skeletons are down, you can attack Micolash until he reaches 50 percent health. During this initial encounter you don't have much to worry about. Micolash uses an extended tentacle arm that many of the other Hunters have used throughout the game. There's a blue spark just before he uses the attack, so dodge left or right when you see it. If you are close enough you can dodge behind him and still have time to land a Charge Attack on his back, followed by a visceral attack (critical strike) for additional damage.

When Micolash reaches 50 percent health he'll disappear. Head out of the room and up the stairs to the right. You need to head out of the mist and up the circular staircase where you'll find two Tiny Gents. The first uses a whip while the second has a crossbow. Don't run too far up the stairs or you'll have to fight them both at once. As you move through the area you'll come across multiples corpses. Loot everything to obtain 12 Quicksilver Bullets, 8 Blood Vials, a Frenzied Coldblood (9) and a Blood Stone Chunk.

When you find him again he'll run, eventually dropping down to the floor below and running into another Room. This time around a door closes before you can chase him into the final room. Continue moving up, then to the right where you see a square opening in the floor. Squeeze around to the right and drop down into the opening to find Micolash again.

In the final room Micolash fights the same as he did before, only this time he can summon a magic ball above his head that shoots multiple projectile beam attacks. It is imperative that you interrupt this attack or dodge continuously until it completes. Most weapons will interrupt the attack if you're powerful enough. Gun shots can also work in most situations.

Defeat Micolash to obtain the Mensis Cage head attire, then head out of the room down the stairs to the right, then around the corner to the right. Before you round the next corner, look left to see a corpse nearly out of sight near the corner. Search the corpse to find a Kin Coldblood (10), then continue to the right to find an Iron Door Key in the corner.

Essential Tips for Defeating Micolash, Host of the Nightmare

  • The small blue spark near him is a giveaway for when he executes his tentacle attack.
  • You can lay into Micolash in the first room until he reaches 50% health.
