Lost King
Boss
Overview
The Lost King is a massive carnivorous boss creature. It excels as a flying combat mount with high damage output and the ability to breach fortified structures. Players tame it for its devastating offensive capabilities in boss fights and PvP sieges. It can airlift smaller mounts such as Ankylosaurus or Castoroides in its claws for rapid deployment.
Spawn Locations
Lost King does not currently spawn on any ARK: Survival Ascended map, or spawn data is not yet available.
Taming
Taming the Lost King requires a knockout method. Use Exceptional Kibble for the fastest results. Raw Mutton also works but is significantly slower. Immobilize it with a Chain Bola or Bear Trap before sedation. Effective KO weapons include Tranq Arrows and Tranq Darts. The process takes about 20 minutes. Use the calculator below for your settings.
Lost King is not tamable.
Drops & Harvest Resources
Killing the Lost King yields Hide, Raw Meat, and Raw Prime Meat. The Hatchet yields the most Hide, while the Pick maximizes Raw Meat. Dinos specializing in Prime harvest, like the Therizinosaurus, gather the most Raw Prime Meat.
| Resource |  Pick |  Hatchet |
|---|---|---|
| 40%~21~17 hits | 60%~32~13 hits | |
| 60%~24~17 hits | 40%~16~13 hits | |
| 3%~1~17 hits | 2%~1~13 hits |
Estimates based on game-extracted data (weights, quantities, harvest multipliers, damage type chains). Each harvest event independently rolls each resource - higher weight = higher drop chance. Actual yields vary with RNG.
Damage Resistances
The Lost King takes +400% more damage from spike walls, making them extremely effective for defense. It is also highly vulnerable to explosions and melee attacks from metal weapons. Conversely, it has complete resistance to mining drill damage and 50% resistance to ranged turret fire. Focus on exploiting its weaknesses with explosive or spiked defenses.
