Check the taming results to see how long it takes to tame the Rex, what effectiveness you'll achieve, and how many bonus levels it gains. Better food means better results.

Below is a breakdown of knockout weapon requirements for the Rex across various creature levels. Always pace your shots. Torpor takes time to apply, and over-shooting can be lethal.

To simplify the knockout, immobilize the Rex first with Chain Bola or Bear Trap. Alternatively, use a Tusoteuthis to airlift it into a pre-built trap.

The table shows how many sedatives you'll need to keep the Rex 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 0.73 Torpor drain per second, apply narcotics proactively - a wakeup mid-tame wastes everything.

Use the torpor and starve timers to track your Rex 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.

Found throughout the ARKs, the Rex is a tamable, carnivore creature in ARK: Survival Ascended. Classified under the DMG group.

With 1,100 base Health, the Rex is quite durable. With 100% base Melee Damage, the Rex has solid damage output. Stamina sits at 420 base, providing solid stamina reserves. Weight capacity starts at 500, giving it massive inventory space.

Taming the Rex requires rendering it unconscious first - use Tranq Arrows, Darts, or Shocking Tranq Darts to apply torpor. Feed it Exceptional Kibble for the fastest tame and highest effectiveness bonus.

After taming, the Rex is valued for its harvesting efficiency, collecting key resources faster than most tools. 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.
