Maturation has three phases: 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.

Don't skip imprinting - each successful imprint boosts the Brute X-Rex's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

The Brute X-Rex is a carnivore creature in ARK: Survival Ascended.

Stamina sits at 630 base, providing exceptional endurance. Melee starts at 100% - decent hitting power that scales with level-ups. Health-wise, the Brute X-Rex sits at 3,950 base, making it an absolute bullet sponge. A base Weight of 850 means excellent carrying capacity.

The Brute X-Rex is a wild creature that cannot be tamed through conventional methods. Breeding produces fertilized eggs that hatch within a 32°C–34°C temperature window. Killing a wild Brute X-Rex yields 60 base XP. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.

Breeding the Brute X-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 X-Rex matures at a glacially slow pace - plan for a multi-day commitment, 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.

Use the raising calculator to plan food requirements for raising Brute X-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 X-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.
