Defeat Ketheric Thorm Walkthrough

After fighting Knessa Bonedaughter and the others, look for the path behind them and you will find a Restoration that looks like a mushroom. Interact with it to replenish your health to prepare your party for what’s coming.

In the distance below, you will see an area that is separated from the Mind Flayer Colony which seems to be like a grand stage. There's a Neural Apparatus that serves as a lift that will take you to the bottom of the Mind Flayer Colony. Your party is moving closer to Ketheric Thorm and you can sense the Nautiloids stronger down here. At (X:812 Y:-25), you will find another Flesh-Wrought Door, as you interact with it, the Dream Visitor will speak to you, that you have found the location of The Absolute. If you are ready to take the fight, choose Ready, or if you need some time to prepare, go to Campsite and rest.

You will see 3 people engaged in a conversation: Gortash, Orin, and Thorm. They are planning on taking back the Prism from you while they held the Nightsong captive. You hear them that they will proceed with their plans, and expect Ketheric with his army and weapon. All three of them command The Absolute and the colossal elder brain floats from the water below.

They have infected Duke Ravengard with a tadpole and they leave at once to lead the march into the Baldur's Gate while leaving Ketheric behind. You will find Ketheric at the edge of the Chasm, proclaiming his worship for his Lord, and he will fall to it as Myrkul will rise from below. Apostle of Myrkul introduces himself as the Lord of Bones and you will now be fighting him. Remember that Ketheric remains invulnerable as long as he has the Nightsong captured. Your initial goal is to free Nightsong with the Help action, as she is trapped inside a soul cage by Ketheric.

When you bring his HP to 0, Ketheric refuses to die and he returns to deliver his speech and ask for his Master's help. He realizes that there is nothing but silence and that he has been forsaken. He calls out to Isobel before he dies and Dame Aylin swoops down to crush his head repeatedly as the rest of your party watches in horror. With Ketheric gone, you will retrieve Netherstone from him, the one they use to control the elder brain.

With that, The Dream Visitor comes to tell you what has happened. It's the three who were controlling the Elder Brain against its will, or what they call The Absolute. They continue to explain that the Netherstones are what's used to control the elder brain. In order to gain full control, you must collect the remaining Netherstones from Orin and Gortash. They continue to reveal that The Absolute is a front of the Dead Three called Bane, Bhaal, and Myrkul. Each of them has their own Chosen to take part in this attack on Baldur's Gate 3. You will now have these options to ask them:

  1. What do we do now?
  2. What hope do we have if the gods themselves are involved?
  3. I didn't come here to fight gods- I just want my parasite removed.

If you choose the first one, they will tell you to prepare for the fight of your lives, to save the lives of everyone in Faerun. They tell you that the Army of the Absolute is marching towards Baldur's Gate and that the elder brain has the power to turn everyone into Mind Flayers. They tell you that you need to seize control of the elder brain and they will offer to be your shield but asks that you must be the sword.

      Ketheric did not disengage from the first encounter for me and I cant acces this stage. Just downed him too fast and game bugged out

        Gotta say, I celebrated when I defeated Ketheric Thorm, just to see this goddamn beast (spoilers!) this skeleton of Myrkul pop up. Huge deflationary (but epic) moment.

        Then I am fighting this skeleton, trying to figure out what his buffs and weaknesses are, my party and the boss are all getting low on health and can't heal (in his vicinity), it's the Nightsong's turn, she has been whooping ass all fight... And she whiffs on both attacks.

        My main gets sent into the depths with skeleton of Myrkul's next attack, I end up defeating him, but not even the body of my main is anywhere to be seen for the victorious cinematics/dialogue that follow! What a bummer! I guess running around to that side of him was a mistake!
