Saurus 1

Saurus are brutish yet disciplined creatures. Even unarmed, they are extremely dangerous - their sharp claws can gouge grooves into rock or tear out a foe’s throat with ease. Their muscular tails can smash a man’s ribcage and their mouths are full of enormous dagger-shaped teeth. The power of their crocodilian jaws is such that a vicious Saurus bite can sever a limb or crush steel. If not killed outright, those bitten by a Saurus bear infected wounds, often succumbing to a foul fever and dying within a matter of days.
