The X-Rex reproduces by laying fertilized eggs after mating. Incubation temperature must stay between 32°C and 34°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.

Full maturation from baby to adult takes ~3 days and 20 hours (1x rate), progressing 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.

Offspring inherit parental stats and have a small chance to mutate, gaining +2 levels in a random stat. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

Maturation has three phases: Baby (0–10%) lasts ~556 min and requires constant hand-feeding. Juvenile (10–50%) spans ~37h - it can eat from a Trough now. Adolescent (50–100%) takes ~46h - continues eating from troughs, nearly fully grown.

Imprint bonuses are significant: a fully imprinted X-Rex gains 30% extra damage and damage resistance with its imprinter mounted. You'll be asked to cuddle, walk, or feed specific kibble at regular intervals during maturation.

Use the raising calculator to plan food requirements for raising X-Rex babies through all three growth stages. Budget ~556 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.

Adjust the dino count to calculate food for multiple X-Rex babies at once - essential for batch breeding operations. Consider food spoilage when choosing what to feed: Kibble lasts days, while Raw Meat spoils in minutes.

ARK: Survival Ascended features the X-Rex as a tamable, carnivore creature that survivors will encounter in the wild. It belongs to the Variant category.

Its base Melee Damage sits at 100%, giving it solid damage output. The X-Rex has 1,100 base Health - quite durable. Stamina sits at 420 base, providing good endurance. Weight capacity starts at 500, giving it an enormous weight pool.

To tame the X-Rex, you need to knock it unconscious using torpor weapons, then feed it while it's down. For best results, use Exceptional Kibble - it gives the highest taming efficiency.

As a tame, the X-Rex is a versatile tame with a balanced stat spread, useful in a variety of roles. Breeding produces fertilized eggs that hatch within a 32°C–34°C temperature window. A wild X-Rex is worth 30 base experience when killed. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
