THIS IS FOR FUN I DO NOT RECOMMEND TAKING THIS SERIOUS!
I got bored one day and I told a friend I was gonna make a Jungle Karma build .. And well here I am I made it, I have played over 30 custom games of me just doing the jungle, I've gotten to level 6 in 7 min and 20 seconds was my fastest.
Well I tried out a lot of different combinations and I found this one was the best combination of runes to have. The flat health marks help with .. having health, flat armor makes you a bit more durable when fighting the golem and lizard for the buffs, flat health quints for even more health.
I still look at the masteries like "What the hell?" so I assume you are too, you need the damage on the minions since your main source is auto attacking, I will explain more in-depth in the Jungle chapter.
The hextech revolver basically is your madreds/wriggles, with it you won't die in jungle with the 15% spell vamp and the 40 AP gives you some more damage and shield. The rest of the items is for your supporting your team, if you're wondering "You're in the jungle .. Not with your team.." I'll explain in the explanation of the Jungle.
I've tried it with Heavenly Blade first, and it's okay.. But the shield is a bit better I noticed as I went through the jungle a couple times I've actually died because of heavenly blade, so I found that the shield is better.
I tried multiple combination's of summoner spells but the fortify and smite I see is the best, the 9 minion damage helps a lot plus if you're top can't handle being alone guess what? Fortify! Helps a lot late game when the jungling phase is basically over and you're just a normal support.
Creeping / Jungling
Alright, you're probably like "WTF" at this point, "Jungling support?!" I know crazy. When you start jungle you start at the blue buff or golem, you should live with about 200 or so health if you grab your shield and use it right along with smite killing most of his health, I usually use about one pot and I live. I move to the wolves using another pot killing them is easy when you kill one you should level and the heavenly blade helps, move to the wraiths from there, using a mantra + shield then blade should almost kill the little ones, I auto attack those kill them then kill the big one, I move to lizard from there. I wait a couple seconds letting my mana go up and potting up my health just play smart and try to hit the little guys with your heavenly blade and the big lizard so they die at some point, smite the lizard you should live again with about 200 health, I move to the two golems below him using my last 2 pots taking him out, now comes the iffy part. If you do for some reason decide to go to a normal/ranked game to do this you gotta go to there blue buff and kill it, at this point you should have no items and still have your fort pot which you shoulda used at the first blue buff. Take out the golem, then the wolves then go back to wraiths, then to your wolves. This should put you at level 6 and with 1.4k gold so you can buy your hextech revolver from there, you can either lane. Keep jungling or attempt to gank. Why do you grab aura items and stuff like that? BY the time you get to 8ish your jungle is basically done you start lanning/ganking/helping people as in your supporting them, as in you get support items cause you're a support. Also if that isn't enough of a reason for you, towards the end of the game you're gonna be doing teamfights and having all those aura items helps a lot.
Pros / Cons
The pros double as cons isn't that weird?
Having a jungle can be essential to a team, you the support getting that solo expierence
It's only a minute and 30 seconds slower then Master Yi!
You pick up Fortify.
You're playing a support a vital role to a good team comp.
All of your carries + tank can lane.
You pick up fortify and not clarity/heal to support team.
You can't support a carry in lane.
Slower then Master Yi.
