Skills:[/b] Snakes have a +4 racial bonus on Hide, Listen, and Spot checks and a +8 racial bonus on Balance and Climb checks. A snake can always choose to take 10 on a Climb check, even if rushed or threatened. Snakes use either their Strength modifier or Dexterity modifier for Climb checks, whichever is higher. A snake has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.

Viper snakes rely on their venomous bite to kill prey and defend themselves.
Poison (Ex): A viper snake has a poisonous bite that deals initial and secondary damage of 1d6 Con. The save DC varies by the snake?s size, as shown on the table below. The save DCs are Consitution-based.

Size	Fort DC
Medium	11
