Adaptive Tactics

At 4th level, an Aldori swordlord learns to adapt his fighting style to counter his enemy's strengths. An Aldori swordlord reduces the attack roll penalty for fighting defensively or using Combat Expertise by 1 at 4th level and by 2 at 8th level. In addition, after a creature attacks an Aldori swordlord for the first time, he attempts a Perception check (DC = 10 + the opponent's base attack bonus). If successful, the Aldori swordlord gains a +2 circumstance bonus on attack rolls and to his AC against that creature until the end of combat.
