D20:Whip Weapon

A whip deals nonlethal damage. It deals no damage to any creature with an armor bonus of +1 or higher or a natural armor bonus of +3 or higher. The whip is treated as a melee weapon with 15-foot reach, though you don?t threaten the area into which you can make an attack. In addition, unlike most other weapons with reach, you can use it against foes anywhere within your reach (including adjacent foes).
Using a whip provokes an attack of opportunity, just as if you had used a ranged weapon.
You can make trip attacks with a whip. If you are tripped during your own trip attempt, you can drop the whip to avoid being tripped.
When using a whip, you get a +2 bonus on opposed attack rolls made to disarm an opponent (including the roll to keep from being disarmed if the attack fails).
You can use the Weapon Finesse feat to apply your Dexterity modifier instead of your Strength modifier to attack rolls with a whip sized for you, even though it isn?t a light weapon for you.

Increase total cost for magical enhancement by 2,000 gp for cold iron weapons. Unlike the additional cost, the increase the weapon's hardness and hit points are only gained from its enhancement bonus, not its special abilities. If the weapon has a magical bonus greater than +5 or a special ability worth more than +5, the weapon is epic. Multiply magic cost by 10.
