Hey everyone, this is my first guide. I'm not a pro, but I love playing LoL. Recently I find this build for Rengar pretty effective, so I want to share with you. I'm kinda busy and don't have time to write a long and comprehensive guide, but with the information here I think you can do well!

I use runes for health, armor, and CDR. I start with 94 health, 17 armor, 8.62 CDR.

Use E and W to harass your opponent in lane. This is how I usually do it. When you have 4 ferocity points, either wait in the bush to jump at enemy champion or walk to him. Either way, when you are close, start with battle roar, followed by another battle roar (with regen effect), then Q and E and run back. In this way you should find yourself out-damaging your opponent.

Even if you don't want to push your lane, you may do so unintentionally with your W. So once you push your lane, you can roam to their jungle or to mid to help your teammates. Few champions can 1v1 you in the jungle, so don't be afraid.

You jump in and keep their carries away from your team. You want to use W whenever you have 5 ferocity points. Also, jungle is your friend, so try to initiate there.
