Tek Rex
Variant
Overview
The Tek Rex is a powerful carnivorous variant of the Lightning-Infused Rex. It possesses the ability to stun enemies with its roar, making it a potent combat mount. It can be airlifted by Tusoteuthis for rapid deployment across vast distances.
Players typically tame the Tek Rex for its high damage output and battlefield control through stuns.
Spawn Locations
Tek Rex does not currently spawn on any ARK: Survival Ascended map, or spawn data is not yet available.
The Tek Rex must be knocked out before taming. Use Chain Bola or traps like Bear Trap and Large Bear Trap to immobilize it. Target it with Tranq Arrows from a Bow, Crossbow, or Compound Bow, or use Fabricated Sniper Rifle with Tranquilizer Darts.
Feed it Exceptional Kibble for the fastest taming. About 17 pieces are needed. The process takes around 58 minutes. Use the calculator below for your settings.

Tek Rex Tips & Tricks
The Roar ability stuns enemies within a 75-degree cone up to 35 meters away. Stun effect lasts 4 seconds and has a 60-second cooldown.
After using Roar, the Tek Rex enters a 360-second cooldown lockout period, preventing reuse.
It takes +400% more damage from spike walls, so avoid placing it near such defenses.
The Roar ability has a weight limit of 200; heavier creatures are immune to the stun.
