Rengar's buff states that "Rengar must kill Kha'Zix first to become the ultimate hunter. (Assist count)."
While the buff on Kha'Zix will state "Kha'Zix must kill Rengar first to become the ultimate predator. (Assit count)".
If Rengar kills or participates in killing an enemy Kha'Zix, his Bonethooth Necklace will be replaced with a new item, The Head of Kha'Zix. The Head of Kha'Zix holds the same stats as a fully stacked Bonethooth Necklace, but these stacks cannot be lost upon death The Bonethooth Necklace will become fully stacked regardless of how many stacks Rengar had before killing Kha'Zix.
He will also recieve a new buff icon labeled "Victory!". It reads, 'Rengar has slained his otherwordly nemesis Kha'Zix, proving to the world that he is the ultimate hunter.'
If Kha'Zix kills or participates in killing an enemy Rengar, he will recieve a fourth evolution point.
Kha'Zix will also recieve a buff labeled "Victory!" It says, 'Kha'Zix has slain his bestial nemesis Rengar, evolving into the ultimate predator.'
One final note: Rengar has two hidden phrases when fighting Kha'Zix. If Kha'Zix activates his stealth during Rengar's ultimate, Thrill of The Hunt, Rengar will sometimes say one of two phrases: "I found you, beast!" or "I see you, wretched creature!".
