Kha'Zix gains Unseen Threat when no enemy champion, ward or minion are providing sight of him.
Abuse this passive to see if your enemy champions have warded bushes and key spots in the map.

Well, reading your guide with more patience I see these details that like me and others that don't at all. This is just mostly my opinion.

- We use the exactly the same defensive masteries thing that is a must in this jungler or otherwise jungle eat us.

- Flat AD runes, I noticed that you can jungle better if you get the standard jungler runes (+15% atack speed, +10 armor pen) with a long sword and a potion, then it's built quicker in our favorite early game item the wriggles lamp. I just find more hard to find by items +10 armor pen than +15 atack damage, but the 15 AD in early game it's probably more damage to enemy champions.

- In your build yomous is viable in early for that Lethality mastery. Thing that in mine is not because of my mastery build, so I need to wait to finish the other items to get it =/

- Your kha'Zix is somehow vulnerable to Randuims and frozen heart and it's not said at as known cons.

- I feel that Kha'Zix champion has too many pros and cons, thing that makes it balanced, but probably you should examine with more care to detect these pros and cons what I'm talking about.

- I Like the redaction in some parts, mostly here "What are you waiting for? Go kill Rengar already! Make him sorry he ever entered the League!" XD

- A way too low defensive items that you add as conditionals, no Guardian angel, no Thornmail, I just feel that it needs one of these in some circunstances.

- I don't like at all the frozen mallet idea as item recommendation, +20 AD for about 3100 gold, also adds you durability and perma slow, but I kinda dislike it in kha'zix because with 3100 gold you can find about 85 AD by other items. If you kill faster, you take less damage :)

- I should try it with earlier youmous atleast once, sounds funny. Mixing in a gank, 1st stealth + yomous active.

- silence ruins less your kha'zix than mine, but I guess that in my build blind and silence is more balanced because of the black cleaver.

- I noticed few time ago that 2 doran blades before the brutalizer helps a lot, then I tried and now I'm editing my guide to post it in the item build secuence. +20 ad before +10 armor pen is I think more helpful in early game, appart of that +6% life steal and +160 health.

well, that is why I observed for now, just want mostly to read your opinion of each point that I gave.

Needlous: Yeah, I guess your definition is more technical :P
MasterKitty: Ionian boots are helpful in some circumstances. Maybe I'll add it to the Situational Items.
MagicBloodline: Sure thing! I'll get on it as soon as I can!

from the looks of it, this guy is good... imma try it out a few times and give u the resaults... but I also (like magicbloodline) think that Ionian boots are better for zix... but than yet, you are right... it's only a matter of persional opinion. :)

"Kha'Zix gains Unseen Threat as soon as no enemy champion is providing sight of him. This does not take into account enemy minions or wards."

But that is why the black cleaver is good, if you take out 45 of their armour they have almost null armor againist you, appart of the beneficted atack speed and mixes too good with your armor pen of 20 from runes and brutalizer. So it's true damage after 3 strikes to these enemies that have less than 65 armor, so this mean almost any carry at lv10s-lv13 will take true damage from you.

Also for my build it's a must getting it before the blood trister mostly because I don't go for berserks, so for compensation, I need that +30% atack speed earlier :P

Hey man, I have a Kha'Zix guide too, would like what do you think about reading it or part of it, need some feedback and some more views xD

I find Berserker's greaves to be more useful than the Ionian boots, but that's just personal rpeference, I guess :P. I rush a Bloodthirster for the early damage it provides (I do think Youmuu's is a better option earlier, which is why I put it there). If you can get a fully stacked Bloodthirster, you have quite a powerful character at your disposal. While Black Cleaver is also a very nice item, I don't feel it helps enough mid game because it's only late game that people have massive amounts of armor, and that's when you need a cleaver. However, you can put a cleaver before the Maw of Malomortius if the enemy team is building armor. And I'm going to put in a situational build guide, just not done with it yet.

I use most of your items in my Kha'Zix, but I kinda preffer Ionian boots in it instead of berserkers greaves, I would get black cleaver earlier, even before the Blood Trister because it's 45 armor breaking (it's exactly the same than a chain vail armor) and I preffer lowering leap's cooldown by maximizating it first (it has about 7-8 seconds of coolodwn if you have like a 40% cooldown reduction) it's the conventional in a normal gap closer and in a chase it's a considerable bonus. The detail that I leave for the W casting is letting it scalling it with the AD from my items because I don't like at all that skillshot, a way too slow the projectile :P

As you, I use the exhaust, I think it's the best summoner spell in it because compenses the low CC of it, decreases movement speed and damage output of the target, so you take less damage after a gank. Also I notice that the item build needs more ratios for more conditionals, I guess.
