Kha'Zix is a very aggressive champion, that I love because of his "nuking" power. He is great at destroying squishy enemies and also good at not squishy, with the Leap to close in, the Taste Their Fear to blow the hp out of them and the Void Spike to finish them/slow in case it isn't enough. I recommend this champion to almost every assassin/burst kind of LoL player.
Kha'Zix has got a godly burst, and can be considered as/(or even more) OP than Darius, one of the most well known champions for him damage+tankiness.

A vicious Void predator, Kha'Zix infiltrated Valoran to devour the land's most promising creatures. With each kill he absorbs his prey's strength, evolving to grow more powerful. Kha'Zix hungers most to conquer and consume Rengar, the one beast he considers his equal.

When Kha'Zix crossed over into this world, he was fragile and ravenous. The animals he first encountered were too small to fuel the rapid evolution he craved. Kha'Zix focused his hunger on the most dangerous creatures he could find, risking his life to satisfy his need. With each kill he feasted and changed, becoming a stronger, faster predator. Kha'Zix soon chased his prey with unrestrained aggression, believing he was unstoppable. One day, while savoring a fresh kill, the predator became the prey. From cover a creature pounced in a blur of fangs and steel, tackling him to the ground. It roared in his face slashing and clawing, and Kha'Zix felt his blood spill for the first time. Screeching in fury, he sliced at the brute's eye driving it back. They fought from sunset to sunrise. Finally, near death, they reluctantly separated. As his wounds closed, Kha'Zix burned with anticipation at the idea of devouring one who could match the Void's strength. He resumed his search for powerful prey with renewed vigor. Someday, Kha'Zix will feast on Rengar.

''Kill. Consume. Adapt.''
-- Kha'Zix

Kha'Zix has a skill set which grants him the burst i love:

Taste Their Fear- A small range skill that does moderate damage to non isolated enemies, and EXPLOSIVE damage to isolated enemies. Minions and teammates are the non-isolation factors.

Void Spike- Kha'Zix shots a spike that deal damage and explodes in a small AOE damage. If Kha'Zix is in the range of the explosion he gets healed (bonus heal comes in AP form).

Leap- this is his jump skill. It hasn't got much to say about but that Kha'Zix jumps to the target dealing moderate damage (it is also a crucial skill for Kha'Zix because it is great for chasings, both when you hunt or are being hunt)

Void Assault- here is when it gets tricky. The ability is a simple stealth for one second that can be activated twice and grant bonus movement speed during invisibility, but you also get a skill evolution point...

I choose maxing Taste Their Fear first because it's the core ability. Without it, Kha'Zix wouldn't do almost any damage, and it is great for early game pokes. After it, i max Leap to gain proximity/to finish the enemy. I max Void Spike in the end because they get very big damage and utility as finisher blows when you have your item set built.

This is what makes Kha'Zix special (and also what makes Void Assault usefull in most parts). Despite his ability ponts, Kha'Zix also gains one evolution point per point he puts on Void Assault.

This is the explanation for each evolution:

Q- Taste Their Fear: you gain bonus 12% of targets missing health as damage to isolated enemies. Kha'Zix's basic attacks and Q's range is increased by 50.

W- Void Spike: now shots 3 projectiles in a cone form, consuming Kha'Zix's passive to slow and DEAL BONUS MAGIC DAMAGE

E- Leap: increases Leaps range (a very, very big range increase) and on kill or assist, Leap's cooldown is refreshed.

R- Void Assault: you can now go stealth 3 times and when you are invisible you get 40% reduced damage taken

You only get to evolve 3 of them so this is my (this is almost completely situational) sequence:

> >

Taste Their Fear first because of the damage bonus and of the range increase.

Leap second because it is a very crucial skill too, which by getting an evolution point, you get gigantic range, not only to chase them down, but also to juke and works as a very improved Flash.

Void Spike gets the increased damage more late game because you should evolve it later, so you get the full Unseen Threat damage bonus (and the slow is also great).


Another Sequence- if you are getting harassed, and if you can't seem to keep up, you better evolve Leap first, for great escapes.

One More Sequence- if the enemy is slipping throught your fingers alot, you should evolve Void Spike so it will slow the enemy at range by consuming Unseen Threat. This works as Rengar's Bola Strike.

Just One More- if the enemy jungler ganks you a lot, or even if you decided to take solo lane and they come in pairs that you can't handle, try evolving Leap or Void Assault for the great escapes/triple high defense invisibility.

My skill combo is:

> > >

You use Void Spike first to do small, but always good damage (poke that target).
You then use Leap to gain proximity for Taste Their Fear.
Taste Their Fear is the core. By using it on isolated enemies they will lose almost half of their HP, and even if they arent, it has always big damage.
You should hit a basic atack after that to use your passive and slow + get bonus damage.
Use Void Spike to finish him/start the combo again.

You have now two options:

Doran's Blade first for very aggressive beggining and to get a possible and totaly not by diving first blood.

Boots and Health Potion because boots will always be boots and pots for sustain.

First Recall:

You will get this if you got Boots in 1st place, so that you get the bonus AD and health.

You get your Boots if you went for doran’s blade in 1st place, so that you get the movement speed

Now this is the item for your early game dominance. The Brutalizer has 25 AD (more than what you would get from a second Doran's Blade); 10% cooldown reduction (spam the Q to kill them faster and don’t give them time to think) and 15 armor penetration (pretty self explanatory; they will buy armor, if they are smart).

Core Build:

The new Black Cleaver is great, now it not only gives you 55 AD and that beautiful passive (might have lost the attack speed, but it is not that bad) it now gives 15 armor penetration, 10% cooldown reduction and 250 health. A great combo for Kha'Zix

Besides Black Cleaver, this is the only source of health in this build, which is like a Warmog's Armor, but it has AD and THE SLOW

This new item is great, not only it takes the splash effect only seen in Tiamat, but it has 75 AD (20 more than Tiamat if im not wrong), 10% life steal and the splash benefits from life steal.

This item is great. It has now 70 base AD and 12% Life Steal, with all the stacks on it, it will have 100 AD and 18% Life steal, which is great now that your attacks splash and your Taste Their Fear damage is greatly increased.

The Infinity Edge isn't in the core items for one reason: i needed to have an item that was switchable, and i looked well into the build and that was it: besides the AD it isn't that good, even thought the 25% critical will help activating Frenzy (not this frenzy...the mastery frenzy)

Boots:

If you aren’t doing perfectly, neither horribly, this item is to help you achieve perfection, with the attack speed bonus you now have something to do when your Q is on cooldown: SLICE HIM WELL AND FAST.

- If you are doing perfectly or VERY well and you just want to get to the fights faster, then buy this item, with the highst speed in game.

Only get this in 2 cases: if the enemy team is full AP or 4 of them are AP OR if they have an heavy CC champion like Leona or Fiddlesticks.

- This is a nice enchantment because besides making your champion look like a derpy ninja running, it will also give you the ability to be a derpy ninja running through your base.

Infinity Edge Options :

If you are already doing the damage, then just buy this to make it a faster, not so skill dependant kill.

This new item is kinda good with the 50 AD, but what really matters here is the second passive: true damage over time, it is great, but you see, with a level 18 champion it won’t be that great, because one doesn’t usually drop the target to 66 health and lets him go. But it may also be good because in the middle of the fight, he wont notice the true damage always damaging him. I haven’t tested if splash damage from Ravenous Hydra also burns the target. If it does, then just buy them both.

This is pretty self explanatory: armor and magic resist. Great. You get a second chance to live. Excellent. You revive then jump the hell away/kill the target!

This item is good because of the CC removing, the 60 AD and the 48 magic resist, buy this if you don’t want the Mercury's Treads and if they have a fed AP caster (I had an experience with a fed Diana, it wasn’t pretty).

Pros +// Excellent at 1v1 +// Great juker with his Leap +// Good sustain due to his Void Spike +// Evolutions make him even more OP +// Looks awesome +// Good early game pokes; destroying late game pokes +// Excellent nuker

Cons -// Not that amazing against non-isolated targets -// You will be focused on teamfights/smallfights -// With this build, a bit squishy -// Rengar will hunt you (you will also hunt him) -// Very vulnerable to champions like Darius and Irelia because of their over damage plus tankiness

I take my Greater Mark of Scaling Attack Damage because late game it is great help with around 22 AD level 18

I take Greater Glyph of Magic Resist for the survivability.

I take Greater Glyph of Critical Chance because if you dont take Infinity Edge, then you wont have critical chance, therefore Frenzy would become useless. The smallest chance is still a chance.

I take Greater Seal of Scaling Armor for the survivability too.

I take Greater Quintessence of Attack Damage for the level 1 dominance and late game bonus.

I made this chapter to show you how your level 18 Kha'Zix will look by the end of this build and for you to see how destructive he will be.

Health: base health, items, masteries
1960+700+250+30=2940

AD: base AD, items, masteries, runes
193+55+30+85+100+70+18.5+11.6+6.75=559.85 AD

Critical Damage: base, items, runes, masteries
100%+5%=105%

Life Steal: items
18%+20%=28%

Armor Penetration: items, masteries
15%+14%+22.5=51.5%

Summary:
Health: 2940
Attack Damage: 559
Critical Damage: 105%
Life Steal: 28%%
Armor Penetration: 51.5%

PHASE 1: lasts for about 10 seconds and is called HARASS

Doran's Blade-You take that Doran's Blade for something. Harass your opponent (ONLY IF IT IS A SOLO LANER) before the minions are even there with Taste Their Fear, if you get your first blood, great, if you don't, nice anyways, because the target will be scared to death from you: you can start PHASE 2: FARM FARM KILL.

Boots and Health Potion- If you decided to go for this option, dont dive in the fight (unless you already have runes) or dive in the fight if you have a partner and the enemy is soloing/doesnt have runes.

PHASE 2: lasts until the mid turret gets destroyed (either your team's or the enemy's) and PHASE 3 starts (LATE GAME MADNESS) this phase is called: FARM FARM KILL...

After you scared him of to base farm (be smart, ONLY last hit) as much as possible to get overleveled against him. When he gets back poke him with Void Spike so he can know you have also ranged pokes (scare him more). Keep on farming until you think you can kill him (by the time you get a Sword of the Occult). When MID turret gets destroyed, everyone will start ganking and going mid. Then you can pass to PHASE 3: LATE GAME MADNESS.

Now that everyone is going mid and ganking and CAN JUNGLE (crucial fact), you will be putting a ward in each buff, and advanced ward in dragon and baron (so that they cant counter you when you decide to do any of them). Now, every single time you see anyone from the enemy team there go kill him:
OPTION A: right after he killed red/blue, you will get the buff and the cooldown will be refreshed. You will be fighting an opponent with the buff advantage.

OPTION B: plant youeself in the bushes and steal the buff, then kill him. In this case you will have the buff advantage, but not the element of surprise and the buff ill have lost some time.
Your choice. This is great to get kills because the enemies will be isolated (if they aren't, you will have to be faster and better or you will die).

Also never forget: YOU HAVE A TEAM. When a person plays with Kha'Zix, they have some tendency to not get kills sometimes, either because of bad reflexes, or skills on cooldown. DON'T BACK AWAY FROM YOUR TEAM BECAUSE OF THAT! If you want you can ask them to let you get some kills, or walk around with the support!

Kha'Zix is a beast late game, and if you want, you can walk alone, but you must be very experient and know what you are doing.

The jungle ganks earlierly (is this the way to spell the word?) mentioned are supposed to be done alone, because one does not jungle with a bodyguard, and if one does, then you are getting a double (if there's a Rengar on the enemy team, BE SURE TO KILL HIM BY LEVEL 16 BEFORE HIM BEFORE STARTING ANY OF THIS.

On every wall of his den, the trophy hunter Rengar mounts the heads, horns, claws, and fangs of the most lethal creatures in Valoran. Though his collection is extensive, he remains unsatisfied, tirelessly seeking greater game. He takes time with every kill, studying his prey, learning, and preparing himself for the next encounter with the one monster he never managed to defeat.

Rengar never knew his real parents, but was raised by a human who was revered as a legendary hunter. He was an ideal pupil, intently absorbing the lessons of his father, and improving them with his uncanny feral instincts. Before his mane had fully grown, Rengar set off on his own and claimed a wide territory for himself. Along its perimeter, he mounted the skulls of his slain prey - a warning to would-be aggressors. He thought undisputed reign of a region would fulfill him, but instead, he grew restless. No beasts in his domain proved challenging prey, and without formidable adversaries to push his limits, Rengar's spirit waned. He feared that no worthwhile game remained, that he would never again feel the thrill of the hunt. Just when things seemed their bleakest, he encountered the monster. It was a disturbing, alien thing, distinctly out of place in his world. It bore huge scything claws and devoured any animal that strayed across its path. Overzealous at the prospect of a challenge, Rengar ambushed the monster in haste. It far outclassed anything he'd hunted before. Their fight was savage, and each suffered crippling wounds. Rengar lost an eye, but the most grievous blow was to his pride. He had never before failed to make the kill. Worse yet, the severity of his injuries forced him to retreat. Over the following days, he hovered on the threshold between life and death. He was wracked with pain, but beneath it, he felt a glimmer of joy. The hunt was on. If such powerful beings existed in the world, he would find them, and stack their heads high. The monster, however, was a kill he wanted to savor. On his den's largest wall, he reserves a space for the beast's head, a trophy he swears will one day be the centerpiece of his collection.

''Prey on the weak and you will survive, prey on the strong and you will live.''
-- Rengar

Rengar is Kha'Zix's biggest enemy. You get a special treat by killing him (assists also count) before he kills you (from level 16/over).

By killing Kha'Zix, Rengar will get all of hid bonetooth necklace stacks, and won't lose them upon dying (in my oppinion, this is much better than Kha'Zix's bonus).

By killing Rengar, Kha'Zix will get a fourth evolution point.


This two champions are -and this is very important- completely balanced:

Kha'Zix Taste Their Fear: the main damaging ability-280+2.4xAD Void Spike: deals 235+0.9xAP and heals for 160+0.5 AP Void Spike: ( Unseen Threat) slows the target and deals 225+0.5xAP magic damage Leap: jumps to target with BIG range and deals some damage Void Assault: goes invisible up to two times

Rengar Savagery: main damaging ability: 1xAD and 100% bonus attack speed Battle Roar: deals 220+0.8xAP magic damage and heals himself for 15% of max health Bola Strike: deals 240+0.9xAD damage and slows the target Unseen Predator: when Rengar is in stealth he can jump into a target (range is similar to evolved Leap's) Thrill of the Hunt: grants stealth, bonus movement speed and unit detection in a large range

Taste Their Fear<---> Savagery
Void Spike<---> Battle Roar
Unseen Threat<---> Bola Strike
Leap<---> Unseen Predator
Void Assault<---> Thrill of the Hunt

The Hunt Is On: ALIEN vs PREDATOR

Let The Most Fed Win!

In conclusion, only go for this build if you know what you are doing because it will be hard due to the squishiness that Kha'Zixhas in this build. This for a Solo Top, but futurely junling, MID and othe parts will be added to complete this.

Hope you enjoyed, this is a build from Nacho Macho
