Revenant Rex
Revenant Rex Egg & Breeding Calculator
Breeding the Revenant 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 Revenant 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.
The Revenant 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 Revenant 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.

Planning a mass raise? The Revenant Rex raising calculator breaks down food needs per phase so nothing goes to waste. The Baby phase (0–10%) takes ~556 minutes and is the most hands-on, requiring direct feeding or a Maewing.
Raising multiple Revenant Rex simultaneously? Set the dino count and the calculator scales food requirements automatically. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

During the Baby phase (0-10%), you must hand-feed or use a Maewing to nurse. From Juvenile (10%+), dinos can eat from a Feeding Trough on their own. Use Preserving Salt in troughs to double spoil times.
ARK: Survival Ascended features the Revenant Rex as a carnivore creature that survivors will encounter in the wild. Classified under the Variant group.
Its base Stamina of 420 gives it solid stamina reserves. Its base Melee Damage sits at 100%, giving it respectable melee power. The Revenant Rex has 1,100 base Health - impressively tough. A base Weight of 500 means massive inventory space.
The Revenant Rex roams the ARK as a wild, untamable creature. Breeding produces fertilized eggs that hatch within a 32°C–34°C temperature window. Killing a wild Revenant Rex yields 30 base XP. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
