Forward calculator. Enter the wild points a creature rolled (and domesticated points you spend after taming) to get each stat's value. Uses official-server rates with no imprint bonus. Melee and movement speed are shown as a percentage; taming effectiveness only boosts stats with a taming bonus (such as melee).

Rates come from your server profile — set them once and every calculator updates.

Raising. The Baby phase (0–10%) is the dangerous window — the baby can't eat from a feeding trough and must be hand-fed until it reaches Juvenile. Imprint at each cuddle interval for the full bonus. Wall-clock times assume the egg is fertilized now and rescale with your server profile; mating cooldown is unaffected. Imprint counts assume the default imprint amount — tune that on the imprint calculator.

Bone Mega Rex guide
The Bone Mega Rex is a creature in ARK: Survival Ascended. This page covers its spawn commands, base stats, taming and breeding — with interactive calculators you can drive by level.
Can you tame the Bone Mega Rex?
The Bone Mega Rex has no taming data in ARK: Survival Ascended — it's typically untameable (or tamed only by special, non-standard means). You can still spawn one already tamed with the GMSummon command above for testing on your own server.
Bone Mega Rex spawn command
To spawn a wild Bone Mega Rex, open the console and run its Summon command. To spawn one already tamed at a chosen level, use GMSummon instead — both are copy-ready in the Spawn commands panel above, along with the raw spawn class (Bone_MegaRex_Character_BP_C) for use with commands like SpawnDino.
