Channels for 1.5 seconds. You can move while channeling and the channel will be interrupted if you cast an ability or enter combat (except minions), putting the item on a 50% cooldown. Activating Predator will not break stealth.
Upon completion, grants bonus movement speed for up to 15 seconds. Grants 45% bonus movement speed for the first 1.5 seconds while moving towards enemy champions, until your next attack or damaging ability, which deals 40 - 120 (based on level) (Adaptive ratio: +40% of Bonus Attack Damage or +25% of Ability Power) bonus adaptive damage.
90 - 60 seconds Cooldown (based on level).
If the bonus damage is triggered via an area-of-effect ability, it will prioritize the lowest-health target hit.
Predator is still weaker than expected, so we’re continuing our fine tuning. Giving it some boosts to help it compete with other keystones.
DAMAGE GROWTH : [30-90] ⇒ 40-120
| COOLDOWN :
||[100-70 seconds (levels 1-18)]
||90-60 seconds (levels 1-18)
While delivering on an excellent fantasy, Predator often loses sights on its prey by having a difficult cast paradigm and unintuitive optimizations. We’re attempting to broaden it from its niche role on a few junglers to making it more of a standard initiation option.
| COOLDOWN :
| DAMAGE :
||[60-180 (+0.4 bonus AD) (+0.25 AP)]
||30-90 (+0.2 bonus AD) (+0.1 AP)
I’M GOIN, I’M GOIN : Active is no longer disabled for the first 150 seconds of the game.
RUN, RUN AS FAST AS YOU CAN Upon completion, Predator now grants 45% bonus movement speed while moving towards enemy champions at a range of 3000, including enemy champions out of vision
CHANNEL INTERRUPTION Active is no longer interrupted if you cast an ability or enter combat (still has a 1.5 second ramp up time for damage effect and full movement speed)
CHARLIE, THAT HURTS Predator now only deals damage and ends the hunt against enemy champions.
DURATION :  ⇒ 10 seconds
Look, a small usability improvement!
ZOOM : The monster burn effect of Hunter's Talisman and its upgrades no longer interrupts Predator's channel
Addressing a few feels-bad parts of Predator.
Predator is still a bit awkward to use, so we're introducing some usability tweaks to make its activation more consistent and its proc more intelligent.
PARTIAL REFUND If Predator's channel is interrupted, 50% of the cooldown is now refunded
HUNT THE WEAK If Predator's bonus damage is proc'd via an area-of-effect ability, it will now prioritize the lowest-health target hit
ADRENALINE Predator's rate of movement speed increase is increased by 50% for the first second and a half of the effect. This is unlisted in the tooltip because if you're making decisions around it, you're probably overthinking things.
Predator has a steeper learning curve than many of our other Keystone Runes because it’s an active effect. However, with such a long cooldown, players don't get to use it regularly enough to progress along that learning curve. Decreasing the cooldown serves two purposes: Giving players more room to experiment with and master Predator, while bringing it more in line with other Keystones.
COOLDOWN : [180-120 seconds (at levels 1-18)] ⇒ 150-100 seconds (at levels 1-18)
THE HUNT IS ON Enchants your boots with the active effect “Predator.” Predator to channel for 1.5 seconds out of combat to gain 45% movement speed for 15 seconds. Damaging attacks or abilities end this effect, dealing 60 - 140 (+0.4 bonus AD)(+0.25 AP) bonus adaptive damage.
COOLDOWN 180 seconds to 120 seconds based on level. Starts the game on cooldown and goes on cooldown if interrupted while channeling.
