I've seen numerous mentions about the interaction of Rengar and Kha'Zix, but I have not seen any tested or official statements regarding it. From what I understand, it comes about when Rengar or Kha' Zix gets a kill on the other champion. The victor receives some sort of buff, but I'm unclear on how to activate the event or what the buff is exactly.

Does anyone have any official/tested information?

  • I saw this for the first time in blind pick normals today... which made me wonder: what happens if Kha'Zix and Rengar are both on both teams? Commented Oct 20, 2012 at 7:42
  • @ChrisPhillips That might be a good question to ask yourself, I know I'd be interested in the answer.

  • Good point. I was going quick and didn't have time to write it up at the time. I've opened a new question: gaming.stackexchange.com/questions/89809/… Commented Oct 22, 2012 at 16:30

1 Answer 1


The gaining of the "Hunt is on" buff is apparently somewhat random. There are two requirements for the buff to come up. 1) Rengar must have the Bonetooth Necklace item, and 2) Kha'zix must have used 3 evolution points (requires him be at least level 16). The exact timing that the buff can start is currently unknown, if it even exists.

If Rengar kills or gets an assist on Kha'zix: Rengar's Bonetooth Necklace will be replaced with the Head of Kha'zix, and will gain a short buff called "Victory!" which as some extra flavor text. The Head of Kha'zix has the same stats as a fully stacked Bonetooth Necklace (regardless of how many stacks it had previously it will be fully stacked as the Head of Kha'zix item) and the stacks won't be lost upon death.

If Kha'zix kills or gets an assist on Rengar: Kha'zix will gain an extra Evolution Point, and gain the "Victory!" buff with some flavor text.


  • Just for clarification, its not random, both champions have to have met the requirement for the "quest" to start. Kha-Zix has to be at level 16 and Rengar has to have the Bonetooth Necklace.

    Is it just me or is the hidden passives getting more and more game changing?

  • It's not just you. Kha'zix's hidden in this case isn't that bad, but Rengar's is game breaking if it occurs (assuming this is accurate).

    @Emerica A Bonetooth Necklace imparts so many buffs at full stacks that it can make a bad Rengar average, an average Rengar great, and a great Rengar unstoppable. Yes, in the extreme cases of a terrible or a fantastic Rengar, the difference might not be as noticeable because the game is already (mostly) won or lost by that point, but in the average case in the middle of the bell curve this is enough to greatly swing the game in the team's favor. That's why it's game-breaking; one kill that triggers a hidden passive shouldn't be the crux of who wins or loses.

    Getting a Kha'Zix kill is a situational answer to gaming.stackexchange.com/q/82302 for Rengars now. Also, note that assists are enough - so a much weaker champ can get in 1 hit, run and leave it to team mates to finish off the enemy Rengar/KZ
