You can make multiple attacks as you ride past your enemies.

Prerequisite(s): Ride-By Attack.

Benefit: When you successfully strike an opponent as part of a Ride-By Attack, you can continue to make attacks against successive targets. You can make one additional attack per 3 tiers you possess, but you can't make more attacks than you could if you were making a full attack.

Successive attacks use the lower bonus for multiple attacks, as when making a full attack. You must move at least 10 feet between each attack.
