Your mixture of close-range combat with the reach of a whip proves a deadly combination.

Prerequisite: Two-Weapon Fighting, Weapon Focus (whip), Whip Mastery, base attack bonus +5

Benefit: When wielding a non-whip melee weapon in your main hand and a whip in your off-hand, you treat the whip as a light weapon for the purposes of two-weapon fighting. While wielding a whip, you threaten the area of your natural reach plus 5 feet.

Normal: Whips are one-handed weapons.

Special: This feat counts as Improved Whip Mastery for the purpose of feat and ability requirements.
