Cooldown: 30 - 15 seconds (based on level)
Fleet Footwork: Successful basic attacks against enemy Champions and Objectives grant you 10 - 35 Movement Speed for 0.75 seconds. Doesn't stack on top of similar effects (such as Phage's Rage passive and Phase Rush) or itself (at very fast Attack Speeds). Cooldown: 1.5 seconds Effective Cooldown: 0.75 seconds
