High Sword Low Axe

(Complete Warrior, page 113, DnD 3.5)

[Style]

You have mastered the style of fighting with sword and axe at the same time, and have learned to use this unusual pairing of weapons to pull your opponents off their feet.

Prerequisite

Improved Trip, Two-Weapon Fighting, Weapon Focus (bastard sword, longsword, scimitar or shortsword), Weapon Focus (battleaxe, handaxe, or dwarven waraxe)

Benefit

If you hit the same creature with both your sword and your axe in the same round, you may make a free trip attempt against that foe. (If you succeed, you may immediately use your Improved Trip feat to gain an additional attack against your foe.)
