A glacier snake has no venom, but its tail ends in a bone stinger that it uses to stab enemies in combat. When wounded, it depends on its fast healing ability to remain alive. Many adventurers have been surprised to see its blood escaping as steam from a wound.

Skills: A snake has a +4 racial bonus on Hide, Listen, and Spot cheeks 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. A snake uses either its Strength modifier or its Dexterity modifier for Climb checks, whichever is higher.
