Variant
Overview
The X-Rex is a large carnivorous variant of the Rex. It can be carried by Tusoteuthis for aerial transport across vast distances. This makes it ideal for deploying high-damage mounts behind enemy lines or to remote resource zones.

Taming the X-Rex requires a knockout method. The best food is Exceptional Kibble, which provides the fastest taming with the highest affinity. Raw Mutton also works but is significantly slower. Use a Bow, Crossbow, or Compound Bow with Tranq Arrows to sedate it. Immobilize the X-Rex with a Chain Bola or trap it in a Bear Trap or Large Bear Trap. About 17 units of Exceptional Kibble are needed. The taming process takes around 58 minutes. Use the calculator below for your settings.
