Rise of the Runelords
A small sized whip
A whip 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 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.
