So I do something weird on Kha that most people wouldn't. I start with my W first, at Blue buff, only using a Machete no pots. This is because Kha can clear Blue (make sure to smite it) and wolves without a problem. Heck he could go and kill everything except Red without going B this way. I don't do this because that would take to long and make you too vulnerable. I instead opt to just clear Blue and wolves this way. I go B grab Madreds Razor and one pot and walk back to wraiths. This has been timed by me and I clear just as fast as a normal start due to Madreds and gain a benefit: I come out of the jungle with higher health than normal and I have an armor bonus the other jungler wont with just the Machete.
