Variant: Tyrannosaurus, Hunting Rex (CR 9)

[Source]

A hunting rex’s teeth can crush bone and extract bone marrow from its prey. They tend to only do this once before discarding a carcass, as their teeth are not well adapted to systematically chewing bone like hyenas do. Hunting rexes are far more subtle in their ways, often hunting a single chosen prey by scent over a very large area.

Bone Crusher (Ex)

If a hunting rex with this special attack begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new grapple check against that opponent. If it succeeds, it deals maximum bite damage (46 points) plus 4 points of Strength damage and 4 points of Dexterity damage and inflicts the sickened condition. If the subject can make a successful Fortitude save (DC 23) he suffers only half damage (both hp and ability damage) and negates the sickened condition. A victim can escape with a successful combat maneuver check or Escape Artist check (DC 39) as a standard action. The save DC is Constitution-based.

This ability replaces the tyrannosaurus’s swallow whole special attack.
