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

Stamina sits at 250 base, providing moderate endurance. Its base Melee Damage sits at 105%, giving it solid damage output. Health-wise, the X-Allosaurus sits at 611 base, making it quite durable. A base Weight of 380 means generous inventory space.

To tame the X-Allosaurus, you need to knock it unconscious using torpor weapons, then feed it while it's down. Feed it Superior Kibble for the fastest tame and highest effectiveness bonus.

After taming, the X-Allosaurus is primarily used for resource harvesting, excelling at gathering specific materials. Breeding produces fertilized eggs that hatch within a 26°C–32°C temperature window. Defeating one in the wild grants 18 base XP. It can be cloned at a Cloning Chamber for 0.53 Element plus 0.01 Element per level.

Planning a mass raise? The X-Allosaurus raising calculator breaks down food needs per phase so nothing goes to waste. The Baby phase (0–10%) takes ~278 minutes and is the most hands-on, requiring direct feeding or a Maewing.

Raising multiple X-Allosaurus simultaneously? Set the dino count and the calculator scales food requirements automatically. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

Maturation has three phases: Baby (0–10%) lasts ~278 min and requires constant hand-feeding. Juvenile (10–50%) spans ~19h - it can eat from a Trough now. Adolescent (50–100%) takes ~23h - continues eating from troughs, nearly fully grown.

Imprint bonuses are significant: a fully imprinted X-Allosaurus 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.

After a successful mate, the X-Allosaurus lays a fertilized egg. Incubation temperature must stay between 26°C and 32°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 1 hour and 39 minutes.

After hatching or birth, the baby X-Allosaurus matures slowly, reaching adulthood in about 1 day and 22 hours at 1x maturation. Hand-feeding is required until 10% maturation. After that, a Feeding Trough handles the rest.

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.
