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

The table below shows how many hits from each torpor weapon are needed to knock out the X-Rex at different levels. Wait between shots for torpor to tick up. Firing too fast can kill the creature before it goes down.

The table shows how many sedatives you'll need to keep the X-Rex unconscious through the full taming duration. Your options are Narcotics (40 Torpor), Bio Toxin (80 Torpor, best efficiency), or Narcoberries (7.5 Torpor, cheapest but slowest). The X-Rex bleeds 0.73 Torpor/s, so keep a close eye on the bar and sedate early.

Track the taming process with the timers below - they monitor both Torpor and starvation progress. The torpor timer alerts you when narcotics are needed. The starve timer tracks Food depletion for starve-taming, where you let the food bar drop before placing all food at once.

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 primarily used for resource harvesting, excelling at gathering specific materials. 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.
