Notes

  • Celerity grants adaptive stats based on the numerical bonus movement speed, not the percentage - that is to say, every 1 movement speed you have above your base. As such, champions with higher base movement speed will gain more adaptive stats from individual sources of % bonus movement speed.
  • The flat bonus movement speed from boots is equally effective on all champions. For example, Boots of Speed item Boots of Speed and Celerity together grant (2.50.0375 = ) 2.5375 AP or (1.50.0225 = ) 1.5225 AD.
