Upgrades one of your champion's abilities, empowering the ability's cast to summon a clone of your champion that is untargetable and moves up to 500 units towards your cursor. The clone then casts the ability it was summoned from after a 0.25-second delay, mimicking the active effects of the casted spell and disappearing after it finishes casting. Clone movement speed is 1000. Clone has a maximum lifetime of 7 seconds.
