Pros Cons
Great burst Counter jungled easily.
Easy ganks No escape
Natural Sustain Ulti countered by Oracles.
CC
Bonetooth Necklace SO SEXY.

Rengar is a great champion. He has no costs for his ability and his Ferocity builds up quickly after level 2. His damage and sustain is quite hefty. I believe that with his passive he is made to jungle. You may lane him because of his sustain with his W, but this guide focuses on all things jungle.

You can switch the runes with whatever standard AD jungle runes you prefer.

This is a somewhat standard jungle mastery setup. The support masteries give longer red buff for ganks. Once you play Rengar enough to become #1 NA you can switch the 9 in support over to offensive masteries.

Blah Blah Blah, 100 armor / 100 MR / 3000 hp / 350 AD / Permanent slow / Life steal / WHAT MORE DO YOU WANT?

If you are have a team with little CC or having a hard time with ganks, Max your E before your W!

Smite is smite is smite is god. For secondary summoner spell I recommend either Flash or Ghost so that you can do TONS OF DAMAGE! Though of course a great substitute is Exhaust.

Route.
Red Buff
Proceed to either Wraiths or early gank Mid / Bot lane.
Golems
Wolves
Give Blue buff to your Mid lane you damn *****!
Ganks / re-route.

Rengar is definitely an all time best champion for me. He suits my play style and can be played a few different ways. I understand the guide is bare bones and isn't fancy, first guide and typed it up in about 30 minutes. Please leave responses, if you feel you want to help or if you just want to vent.
