Hello Dear Kha'Zix players
As we all know Kha'zix is an alien whit sick dmg mid and late game.
Thats why i made this build,
let's get this started

First ability you want to evolve is TASTE THEIR FEAR
Second is ur VOID SPIKE
Last but not least ur LEAP

Kha'Zix got a Hidden passive, if the enemy got a rengar you will receive a quest at lvl 16
DON'T LET THAT BASTARD TAKE YOUR HEAD!!! Instead, you should take his other eye as a proof of your evolution! Besides that "hidden passive" for a fourth evolution point that I mentioned before (that still a rumor), Kha'Zix and Rengar shares much more gameplay. Playing as Kha'Zix, YOU NEED TO MAKE THAT FREAKING BEAST REGRET FOR ENTERING THIS LEAGUE. Make sure the treatments when you play against a Rengar is like a relation between a kitten and a feral evolutionary Void monster, not a lion and a praying mantis. If you lose for a Rengar, you shouldn't be playing Kha'Zix at first! And if you're going to play Kha'Zix and some idiot on your team picks Rengar, DODGE THIS QUEUE! You're going to lose with this stupid kid on your team, trust me.
For those who don't get it yet, I'm just joking

Cons



- Squishy (because he's an assassin)
- Is an assassin, does not fit the current meta
- Somewhat hard to play (since it's an assassin)
- Shut down easily
- Loses his head to Rengar

Flash. Just Flash. I love this spell, as it provides an excellent escape mechanism, great juking potential and may also (but is NOT the objective) secure a kill. If you don't like it, take Ghost in lane, because you NEED an escape mechanism, and Ghost or Exhaust in the jungle for better ganking.
On a lane, you can choose Exhaust or Ignite for offensive spell, personal choice, but do not take Exhaust if your jungler already have.

Standard 21/9/0 will do it

Just Armor Pen Marks
