Your dual bludgeoning strikes are especially deadly when you are fighting giants.
Prerequisite: Dwarf or gnome; defensive training racial trait; Improved Two-Weapon Fighting and Two-Weapon Fighting, or flurry of blows class feature; Twin Thunders; Weapon Focus with both wielded weapons; base attack bonus +6.
Benefit: You can trip a creature with the giant subtype of up to Huge size, and you gain a +2 bonus on damage rolls against creatures of the giant subtype. Further, each time you hit a creature of the giant subtype with your off-hand weapon after you hit that creature with your primary weapon, you can deal the extra off-hand weapon damage Twin Thunders grants you.
