Combat

Whipsnakes usually lurk on sturdy tree branches, ready to drop or slither onto creatures passing underneath. However, they have also been known to lie on the ground, stretched across a trail amid fallen tree branches, waiting to coil around the legs of creatures using the path and trip them. A whipsnake's first attack is always a coil slam.

Coil Slam (Ex): A whipsnake can whip its body against an opponent (+5 melee), dealing 1d4 points of damage on a successful hit. In addition, the target must make a DC 12 Reflex save to escape the coils. Failure means the opponent lands prone in its square, and the whipsnake automatically establishes a hold on it and can constrict as if it had made a successful grapple check.

Constrict (Ex): On a successful grapple check, a whipsnake deals 1d6+4 points of damage.

Improved Grab (Ex): To use this ability, a whipsnake must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.

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.

A whipsnake 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.
