Hi there guys!

I would like to start with explaining why Kha'Zix and why this items? Well, I think Kha'Zix is a verry good jungler because of his abilities are dealing alot of damage in ganks and with his E evolved he can get almost everly kill.
This items also help him with the mobility burst and also slowing your enemies.

Pros

+ High range and mobility.
+Very good ganker.
+ Passive deals alot of damage in combination with your Ultimate.
+ High range and mobility.
+ Evolving makes you even more powerfull.
+ Fun to play.

Cons

- Can be hard to play if u dont play jungle often.
- It can be difficult to gank without your E evolved.
- If the enemies are in a group you deal less damage.
- Often bannend.

For the runes I have chosen for pretty much just the normal runes for an AD Jungler. But it still are nice Runes for the early game and I just love playing with this Runepage.

Greater Seal of Armor Just to get a some sustain at early game against the AD Carry and other high damage AD enemies.

Greater Glyph of Scaling Magic Resist Helps me alot when I'm going to gank mid and just against every AP champions.

Greater Mark of Desolation Is helping me to ignore some armor which makes the AD Carry verry vulnerable because they mostly dont have high and this runes just crush the last bit of armor.

Greater Quintessence of Attack Damage As Kha'Zix is an AD Jungler this realy helps you to get in that extra damage at early game which makes jungling and ganking a lot easier.

Offense

Brute Force +3 Attack Damage, this is always nice.
Butcher +2 Damage at minions and monsters, It can help you a little bit at early jungling.
Alacrity +4% Attack Speed, this will make you clear the jungle a little bit quicker.
Weapon Expertise +10% Armor Penetration, As it says it penetrates the armor of your enemy.
Deadliness +0,5 Attack Damage, 9 Attack Damage at lvl 18. All small things together make 1 big thing!
Lethality +10% Critical Strike Damage, the great thing about Lethality is that when you build a champion on high critical strike rate you do amazing damage.
Vampirism +3% Lifesteal, life steal is always handy on a jungler because you can stay longer in jungle and when u buy some lifesteal u basically can stay jungling forever!
Sunder +6 Armor Penetration, in combination with our other Armor Penetration the squishy champions have no armor left which makes you dealing the full amount of damage and taken them out real quick.
Executioner +6% Damage to target below 40% health, another great masterie which will help u picking up low HP minions and champions a lot quicker.

Defense

Summoner's Resolve +10 Gold on using Smite, the gold you get for every time you Smite is pretty much in total and especially at early game.
Hardiness +6 Armor, a little bit extra sustain against minions, monsters and AD champions.
Durability +106 HP at lvl 18 ( 6 each lvl ), another mastery just to make sure you can keep jungling a little bit longer and have some more sustain.
Veteran's Scars +30 HP, you get the HP right in the beginning of the game which makes you less squishy and gives you that little HP buff.
