You are more effective in combat against your racial enemies.
Prerequisite: Kobold.
Benefit: When you hit a dwarf, fey, or gnome with a melee attack, you deal an extra 1d6 points of damage if you flank the creature, or if it is fl at-footed. Creatures immune to extra damage from critical hits or sneak attacks are not subject to this extra damage. Any creature with concealment is immune to this extra damage.
Special: A kobold fighter can select Kobold Foe Strike as one of his fighter bonus feats.
