Ketheric Thorm is the final boss in Act II of the main story and defeating him is not as easy as rushing towards him and blowing him up with barrels or blasting him with spells.
This immortal conqueror holds a secret, which prevents him from dying, and through the course of Act II, you need to find a way to defeat him.
Eventually, you will have to face him at Moonrise Towers and after progressing with the story and the right preparation, this immortal being can finally be put down.
Where To Find Ketheric Thorm?
Moonrise Towers
The first few times that you encounter Ketheric Thorm, he will be on top of Moonrise Towers, and you can head up there by making your way past his minions.
This will involve either fighting your way through them or going along with their plot until you get the chance to attack Ketheric Thorm. (After freeing the Nightsong)
Mind Flayer Colony
Once you reach the Mind Flayer Colony, you will have to explore the area until you find Ketheric Thorm, who will be in a meeting with the other leaders of the Cult of the Absolute.
You will need to use the Neural Apparatus on a platform in the area located east of the Mind Flayer Colony to reach the entrance to where they are located.
Defeating Ketheric Thorm
Ketheric Thorm may only be damaged once you have freed the Nightsong and once this happens, she will fly over to the Moonrise Towers to attack him.
As you reach the rooftop, you will be able to start the fight with him and the Nightsong will help you until his health is reduced, which starts a cutscene.
Ketheric Throm escapes into the Mind Flayer Colony, where you will pursue him until you enter the phase for the final fight.
After following Ketheric Thorm into the Mind Flayer Colony, you will have to fight him again, but the Nightsong will be imprisoned.
You will need to free her by interacting with her during the fight and this can easily be done by using Dash or spells like Misty Step to get close enough to free her.
Once the Nightsong is freed, continue fighting Ketheric Thorm until he is weakened and a cutscene will begin where he purposely falls into the large hole behind him.
This causes the Apostle of Myrkul to emerge, and you will need to defeat this boss before you can interact with Ketheric Thorm’s body.
This enemy will be a bit tougher than most foes that you have gone against but with the help of the Nightsong, you can make short work of it.
Defeating the Apostle of Myrkul will cause Ketheric Thorm to appear and he soon falls to the ground and has his face stomped several times by the Nightsong.
Ketheric Thorm Drops
Interacting with Ketheric Thorm’s body will have you take the item called Ketheric’s Netherstone in a cutscene and his inventory will be opened after.
Looting Ketheric Thorm’s body will allow you to obtain the following:
- Crumpled Note
- Ketheric’s Warhammer
- Supply Pack
- Ketheric’s Shield
- Reaper’s Embrace
Verdict
Defeating the Ketheric Thorm can only be done after you have freed the Nightsong, which makes it necessary to progress with the main story.
During the fight with Ketheric, it is important to make your way to release the Nightsong after she had been previously captured to damage him.
The final fight can be tough but with proper positioning and strategic use of your characters, both Ketheric Thorm and the Apostle of Myrkul may be defeated.
