More about taming the Tek Rex
Use the calculator results to plan your tame - they show the exact time, food quantity, and bonus levels for the Tek Rex based on your settings.
The table below shows how many hits from each torpor weapon are needed to knock out the Tek Rex at different levels. Always pace your shots. Torpor takes time to apply, and over-shooting can be lethal.
To simplify the knockout, immobilize the Tek Rex first with Chain Bola or Bear Trap. Alternatively, use a Tusoteuthis to airlift it into a pre-built trap.
Use the narcotic calculator to determine exactly how many Narcotics, Bio Toxin, or Narcoberries you need for the Tek Rex. Your options are Narcotics (40 Torpor), Bio Toxin (80 Torpor, best efficiency), or Narcoberries (7.5 Torpor, cheapest but slowest). With Torpor draining at 0.73/s, don't wait until the bar is nearly empty to apply narcotics.
The real-time timers below help you monitor Torpor drain and Food depletion during the tame. Starve taming is recommended for valuable high-level Tek Rex: let the Food stat deplete first, then add food. This way nothing is wasted if something goes wrong.
Found throughout the ARKs, the Tek Rex is a tamable, carnivore creature in ARK: Survival Ascended. It belongs to the Variant category.
Dealing 100% base Melee Damage, the Tek Rex brings decent hitting power to the table. The Tek Rex has 1,100 base Health - solidly tanky. Stamina sits at 420 base, providing good endurance. It carries 500 base Weight - excellent carrying capacity.
You'll need to knock the Tek Rex unconscious before taming it. Tranquilizers are the standard approach. For best results, use Exceptional Kibble - it gives the highest taming efficiency.
Once tamed, the Tek Rex is primarily used for resource harvesting, excelling at gathering specific materials. It reproduces by laying eggs, which must be incubated between 32°C and 34°C. Defeating one in the wild grants 30 base XP. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
