Titan Fighting
( Races of Stone, p. 145)[Racial]
You have been trained to fight larger creatures, and you are adept at dodging their attacks.
Prerequisite
Dodge (PH) , racial dodge bonus to Armor Class against monsters of the giant type,
Benefit
When you designate a creature at least one size category larger than you as the target of your Dodge feat, you apply your racial dodge bonus to Armor Class against monsters of the giant type against attacks from that opponent (regardless of its creature type) instead of the +1 bonus granted by the Dodge feat.
Special
A fighter may select Titan Fighting as one of his fighter bonus feats (see page 38 of the Player's Handbook).
