The new expansion and all the related content revolve around the Arat Prime map. There are two main bosses on the new map: the Lost King and the Lost Queen. This guide will provide you with all the essential information to know if you’re looking to complete the expansion as quickly as possible.
All ARK Survival Ascended bosses in Lost Colony DLC
As mentioned earlier, there are two main bosses to take down: Lost King and Lost Queen.
Lost King
The Lost King is the main boss of Arat Prime. We already knew about his looks, all thanks to the trailer. You can find him at his palace, which is the hardest stage to complete. To enter, you’ll need to craft a Red-Handed relic. Lost King comes in three different variants, with each having its own requirements.

Alpha
- Five Alpha Ossidon Skill
- Ten Alpha Zombie Brainn
- 200 Prime Aberrant Sigil
- 200 Prime Crimson Sigil
- 15 Neophyte Horns
Beta
- Onne Alpha Ossidon Skull
- Five Alpha Zombie Brain
- 150 Greater Aberrant Sigil
- 150 Greater Crimson Sigil
- Ten Neophyte Horns
Gamma
- One Alpha Zombie Brain
- 100 Minor Crimson Sigil
- 100 Minor Aberrant Sigil
- Five Neophyte Horns
The Lost King is one of the most challenging enemies to take down, but doing so has its own rewards. For one, you get to complete the new story, which is pretty intense. This is also the only legitimate way of gaining a Gigadesmodus for yourself.
Lost Queen
Once you defeat the Lost King, you’ll have to face the Lost Queen. You’ll get to know that she was defeated by Lost King, who made her his queen. The location is the same as the fight directly transits to Lost Queen.
Like Lost King, the Lost Queen battle will have mutople phases. Once you deal enough damage, she will become temporarily immune. You’ll then have to break the beam to prevent her from healing and continue the fight.
Once you defeat her, interact with the codex to lower the castle shields and turn the Arat Prime back to its original form. Defeating the Lost Queen officially completes the full Lost Colony DLC campaign.
