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.

The table shows how many sedatives you'll need to keep the X-Allosaurus unconscious through the full taming duration. Bio Toxin is twice as potent as Narcotics (80 vs 40 Torpor per use), while Narcoberries work in a pinch at just 7.5 Torpor each. At 0.8 Torpor drain per second, apply narcotics proactively - a wakeup mid-tame wastes everything.

Use the calculator results to plan your tame - they show the exact time, food quantity, and bonus levels for the X-Allosaurus based on your settings.

The X-Allosaurus is a knockout tame - render it unconscious with torpor weapons like Tranq Arrows or Shocking Tranq Darts, then feed it while it's down. Torpor bleeds at 0.8/s, requiring regular sedative application to prevent a premature wakeup.

Use the torpor and starve timers to track your X-Allosaurus tame in real time. Torpor monitoring prevents premature wakeups. The starve timer is for the starve-tame method - let Food drop, then load all kibble at once to avoid waste.

The table below shows how many hits from each torpor weapon are needed to knock out the X-Allosaurus at different levels. Always pace your shots. Torpor takes time to apply, and over-shooting can be lethal.

To simplify the knockout, immobilize the X-Allosaurus first with Chain Bola or Bear Trap. A Quetzal can also pick it up and drop it into a taming pen for a controlled knockout.
