ARK: Survival Ascended features the Brute Malfunctioned Tek Rex as a carnivore creature that survivors will encounter in the wild.

Its base Stamina of 630 gives it massive stamina reserves. Its base Melee Damage sits at 100%, giving it decent hitting power. Health-wise, the Brute Malfunctioned Tek Rex sits at 3,950 base, making it an absolute bullet sponge. Weight capacity starts at 850, giving it an enormous weight pool.

The Brute Malfunctioned Tek Rex roams the ARK as a wild, untamable creature. Breeding produces fertilized eggs that hatch within a 32°C–34°C temperature window. A wild Brute Malfunctioned Tek Rex is worth 60 base experience when killed. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.

The Brute Malfunctioned Tek Rex's growth progresses through three stages: Baby (0–10%) lasts ~556 min and requires constant hand-feeding. Juvenile (10–50%) spans ~37h - it can eat from a Trough now. Adolescent (50–100%) takes ~46h - continues eating from troughs, nearly fully grown.

Imprint bonuses are significant: a fully imprinted Brute Malfunctioned Tek Rex gains 30% extra damage and damage resistance with its imprinter mounted. Imprint requests include cuddling, walks, and specific kibble - check the wiki for which kibble to stockpile.

Use the raising calculator to plan food requirements for raising Brute Malfunctioned Tek Rex babies through all three growth stages. The Baby phase (0–10%) takes ~556 minutes and is the most hands-on, requiring direct feeding or a Maewing.

The multiplier feature helps plan large-scale Brute Malfunctioned Tek Rex raises by totaling food across all babies. Consider food spoilage when choosing what to feed: Kibble lasts days, while Raw Meat spoils in minutes.

Breeding the Brute Malfunctioned Tek Rex produces fertilized eggs that require careful temperature control. Incubation temperature must stay between 32°C and 34°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 4 hours and 59 minutes.

After hatching or birth, the baby Brute Malfunctioned Tek Rex matures over many real-world days, demanding serious time investment, reaching adulthood in about 3 days and 20 hours at 1x maturation. The most labor-intensive part is the baby phase (0–10% maturation) when it can't use a Feeding Trough yet.

Offspring inherit parental stats and have a small chance to mutate, gaining +2 levels in a random stat. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
