Khazix runes

I play a ton of kha this season and he is my main jungle pick. With all junglers it's almost required to run flat armor seals in general to make the first clears much more survivable.

Me personally, I take 5% cdr glyphs with the rest scaling mr, and I combo that 5% with 5% from masteries to make it 10% right of the bat. The core thing to understand about when to take cdr and when not to is to take into account of your build, do you need that to hit 40% late game? Or earlier? And so on so forth.

If you are a Q evolve route Kha then the cdr is extremely needed.

scaling magic resistance on your glyph(blue) flat armour seals(yellow) flat damage marks(red) flat damage(quints)

After a lot of experimentation with Khazix in the new jungle, i use AD quints and reds, Armor yellows, and CDR blues, with no MR runes. It's a bit risky, but this gives you the best survivability and clear in the jungle and you can compensate for the lack of MR by getting and (for the health/survivability) later on.
