ARMOR +2: Saurians have scaly skin that acts as leather armor.
  BITE: A saurian’s fangs are Natural Weapons (page 104) that cause Strength+d4 damage.
  ENVIRONMENTAL WEAKNESS: Though not truly cold-blooded, saurians are poorly suited for frigid conditions. They suffer a −4 penalty to resist cold environmental effects, and suffer +4 damage from cold-based attacks.
  KEEN SENSES: Saurians have acute senses, giving them the Alertness Edge.
  OUTSIDER (Minor): Most races distrust saurians for some reason. Perhaps it is their strange ways and customs, their often-sibilant speech, or an ancient subconscious fear of their reptilian ancestors. Saurians subtract 2 from Persuasion rolls with all but others of their kind.
