Taming Results
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.
Required Narcotics
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.
Starve & Torpor Timers
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 105%, giving it solid damage output. The X-Rex has 1,067 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.
