This is my AD carry Rengar build. This build has worked and is still working for me and has not failed me yet. I hope you all like this build. There is video in this build which makes it easier for you guys to understand this build and how I play my AD carry Rengar. I enjoy AD carry Rengar alot and I hope that you do too. I always found the idea of Rengar being an AD bruiser to be quite boring. So what I did was I went the extra mile to post this build on Mobafire for the community to see it for themselves. I find AD Carry Rengar to be similar to AD Carry Malphite, possible, but not as great in ranked because nobody ever tries to do better with it. Just as nobody plays an AD carry Rengar in ranked games, you never see an AD carry Malphite in ranked games either even though his W when maxed by 9 is a super AD steroid and makes AD carry malphite what he is, just like how AD carry Rengar relies on his furiosity and his Q to output high amounts of burst damage while slowing the enemy target with his E.

Pros:
=====
[*] Extremely high burst
[*] Early game advantage due to burst
[*] Great mobility in lane
[*] Great CS potential
[*] Can pick up easy kills and roams well
[*] No mana, energy, and skills dont cost health, giving a great lane stay
[*] Has a self heal that can bring him up to full health in a short amount of time
[*] Can get 3 attacks off very quickly if timed right with furiosity, each stronger than the other
=====
Cons:
=====
[*] Very squishy early and late game and really depends on a tank to initiate team fights
[*] Late game assassin at the most
[*] Easily countered with a frozen heart or a thornmail
[*] Any kind of enemy CC in a team fight is very lethal
[*] Easily countered by champions with a high mobility such as Vayne or Tristana

I enjoy taking a full AD rune page so that I can have this offnsive burst early game that has given me first blood almost every game I have played, it helps with my CS and it even helps to scare off and counter junglers. I can use this massive amount of AD to even steal buffs from the enemy jungler or an unsuspecting mid lane going for blue buff. These runes makes AD carry rengar what he is.

I enjoy taking 21/9/0 masteries because I enjoy that offensive nuke early and late game as an AD carry Rengar. I find the damage to be rediculously high because of my masteries, I would have to say my masteries probably make my damage what it is end game. I believe that these masteries are fine as they have worked and have not failed me yet.

I like to take flash and ignite when I play AD carry Rengar. I believe that flash and my ult provide great get-aways from the enmy team and situation I dont want to be in and my ignite secures both early and end game kills for me in those situations where you barely dont kill your target.

When playing rengar I like to keep my furiosity at a 4/5 as much as possible. There will be video posted here soon on my gameplay with rengar but I like to keep my furiosity at 4/5 as much as possible and jump on the enemy with a double Q. The reason behind 4/5 instead of 5/5 is because I figured, if there was a massive amount o damage dealt to me would I run or stay to fight. So therefore I like to get a regular Q off first so that it inclines them to stay in the fight moreso than they would if you had just taken out half of their health with a single Q.
