The Abyssal Rex reproduces by laying fertilized eggs after mating. 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.

Full maturation from baby to adult takes ~3 days and 20 hours (1x rate), progressing over an extremely long period, one of the longest in the game. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.

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.

The Abyssal 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 Abyssal 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 Abyssal Rex babies through all three growth stages. Budget ~556 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.

Adjust the dino count to calculate food for multiple Abyssal Rex babies at once - essential for batch breeding operations. Consider food spoilage when choosing what to feed: Kibble lasts days, while Raw Meat spoils in minutes.

ARK: Survival Ascended features the Abyssal Rex as a tamable, carnivore creature that survivors will encounter in the wild. It falls within the Variant classification.

Stamina sits at 420 base, providing solid stamina reserves. Its base Melee Damage sits at 100%, giving it solid damage output. At 1,100 base HP, the Abyssal Rex is quite durable. It carries 500 base Weight - massive inventory space.

To tame the Abyssal Rex, you need to knock it unconscious using torpor weapons, then feed it while it's down. For best results, use Exceptional Kibble - it gives the highest taming efficiency.

As a tame, the Abyssal Rex is valued for its harvesting efficiency, collecting key resources faster than most tools. Breeding produces fertilized eggs that hatch within a 32°C–34°C temperature window. A wild Abyssal Rex is worth 30 base experience when killed. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
