First Strike

Effect

Passive: Initiating combat with an enemy champion within the first 0.25 seconds of champion combat, grants 10 g and First Strike for 3 seconds, causing all of your post-mitigation damage dealt against champions to deal 7% bonus true damage. Afterwards, you are granted gold g equal to 50% / 35% of all bonus damage dealt within the duration.

First Strike will be placed on full cooldown without activating its effects after being struck by an enemy champion before you strike them.
