Jungling As a Ranged Champion
If you have the Krug-stun smite buff and stand at juuuuust the right distance from mobs their targeting AI will start to fritz and they'll start spinning in circles instead of attacking you. I haven't found a perfect position for Krugs and wolves yet, but against everything else you take virtually no damage. I was able to do a full-clear before my first back on Kog'Maw.
