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.

The dino is inside an egg, needing specific conditions to incubate and hatch. The ideal temperature range is 80 - 90 °C.

Baby

6:36:49

The hatched dinosaur, now a baby, needs constant attention and food placed directly in its inventory to survive, or a nearby Maewing to take care of its needs.

Juvenile

10% - 50%

26:27:18

The dinosaur reaches the juvenile stage, where it can now eat from a feeding trough, reducing the need for direct feeding.

Adolescent

50% - 100%

33:04:07

The dinosaur reaches the adolescent stage, becoming more independent and able to follow you while continuing to grow toward full maturity.

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.
