Lost King Egg & Breeding Calculator
The Lost King reproduces by laying fertilized eggs after mating. Incubation temperature must stay between 80°C and 90°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 4 hours and 59 minutes.
The baby Lost King takes approximately 5 days and 12 hours to fully mature at default rates - over many real-world days, demanding serious time investment. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.
Mutations can add +2 levels to any stat and change colors. Stacking mutations across generations is the key to min-maxed breeding lines. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
Maturation has three phases: Baby (0–10%) lasts ~794 min and requires constant hand-feeding. Juvenile (10–50%) spans ~53h - it can eat from a Trough now. Adolescent (50–100%) takes ~66h - continues eating from troughs, nearly fully grown.
Don't skip imprinting - each successful imprint boosts the Lost King's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

Planning a mass raise? The Lost King raising calculator breaks down food needs per phase so nothing goes to waste. Expect ~794 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.
Adjust the dino count to calculate food for multiple Lost King babies at once - essential for batch breeding operations. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

During the Baby phase (0-10%), you must hand-feed or use a Maewing to nurse. From Juvenile (10%+), dinos can eat from a Feeding Trough on their own. Use Preserving Salt in troughs to double spoil times.
The Lost King is one of ARK: Survival Ascended's boss creatures, fought in its own arena with a prepared team. It belongs to the Boss category.
With 100% base Melee Damage, the Lost King has respectable melee power. Health-wise, the Lost King sits at 400,000 base, making it extraordinarily tanky. Its base Stamina of 750 gives it exceptional endurance. It carries 600 base Weight - massive inventory space.
Once tamed, the Lost King is a powerful boss creature encountered in a dedicated arena fight. It reproduces by laying eggs, which must be incubated between 80°C and 90°C. A wild Lost King is worth 18 base experience when killed. It can be cloned at a Cloning Chamber for 0.98 Element plus 0.1 Element per level.
