How to survive in the jungle early
Try to start krugs and finish both krugs with your Q so two graves spawn. Then, go to red and kill the small red buff minions with your Q and move near the bush on the right of red buff. In that position, you should be able to reach both the graves at red and the graves at krugs, so you can have 4 mistwalkers to help you live. As long as you sustain a good amount of mistwalkers you shouldn't need potions due to the natural healing on Q. In most cases, you'll want to go for blue before gromp. Invading after blue usually works very well because you have a fast clear with your ghouls and have good early game if you have a few ghouls, so you'll usually pick up first blood as long as you make sure mid and top laners haven't left lane.
