If the bonus damage is triggered via an area of effect ability, Predator will only hit one unit, prioritizing in the following order. If there's more than one unit of the same type the lowest health one will first be prioritized, then the closest one:
Predator's cooldown will be reduced by effects that reduce item active cooldown.
Passive: Your boots gain the active effect, Predator. This item begins the game on cooldown.
Active - Predator: You begin a 1.5 second channel. You can move while channeling and will be interrupted if you receive damage (except minions), putting the item on full cooldown. Activating Predator will not break stealth.
Upon completion, you gain 45% bonus movement speed for the next 15 seconds or until your next attack or damaging ability, which deals 60 − 140 (based on level)(+ 40% bonus AD)(+ 25% AP)bonus Adaptive damage.
Adaptive: Deals either physical or magic depending on which would deal the most damage.
