Starting Items

• What else should you start at this point? Dhuuuuuh?

Core Items

• CDR Boots, to max out your CDR, so you have your ult up all the time. If you are already maxed out at CDR (Cause you built Black cleaver or whatever), go with Swiftness or Mercs, depending on the enemy team.
• Nothing much to say. just a thing of preferences
• Tiamat into ghostblade. The reason: Tiamat gives you more burst + an extra autoreset and ghostblade.. well.. It is probably THE best item for rengar to get. Buy it right after Tiamat. Ghostblade gives you ADDamage, Armor Pen, CDR, Attackspeed and Movespeed activ. Thats pretty much everything you need with rengar!
• Then go for an Hydra. Hydra give's you sustain and the ability to burst even more in less time.
• If you feel like the devil today, build duskblade and kill every ADC that thinks going full offensive without a single defense stat against a rengar is a good idea. But for real, it is a really good item and helps you 1 shot squishys. Dont build it when they have alot of tanks or you cant 1 shot the ADC
• Well, its not a 1 shot item, but if they have alot of splitpushers, which you need to 1v1 you can go for a cleaver. (Gives you more damage in a fight against a tank-ish champ but less 1 shot potential)
• If they have alot of armor buy L.W and upgrade it lategame. Which upgrade you take, depends on the enemy team.

Situational Items

• Okay, i love this item and if im carrying i always buy it. But it depends on your playstyle i guess.
• If im fullbuild, i sell my boots to get trinity. It allows you, to kill people with 1 Combo of your Q - Hydra - Q and still be really fast.
• If you get raped by an AD champ buy one of these (Maybe even two). Dead man's Plate is really strong atm and it even gives you movementspeed! Depending on the Situation you want this Item instead of the other 4.
• If you get raped by an AP champ buy one of these (Maybe even two).
• Getting banshee's is very beneficial, when you get stunned instantly after jumping in.
• tbh i dont like it. It gives you more 1v1 potential against champs like jax, riven etc. but it doesnt really affect your instant burst because the active isnt really that huge for bursting and the passive works with autoattacks. Its good against tanks tho-
• If you want to stay longer in a teamfight or want to take objectives by your own (mainly baron) it can be a good item. Its not the best choice to go but you CAN build it if you want a shitton of sustain in teamfights
• Reaaaally good in almost every game. Lets you make more risky plays. If you fell like, getting bursted down to fast, buy it.
• If they have alot of ap damage, buy it. It gives AD, Pen, MR, and a super strong passive. its worth!
• Can also be somewhat good, pretty much the same as B.T
• If you find yourself in a spot, where you have to jump in, kill someone and then run away because your gona get killed otherwhise, you can build like this. (AP AD Balanced) (You can maybe buy a Trinity instead of steraks or lategame sell boots for it, but it depends on the game)
• This is my typicall build, when im carrying the game(Mostly against squishys), by 1 shoting people. You can even 1 shot tanks with this. BUT if you get stunned once, you are SOOOOO dead.
• Criiiiiiiit buiiiiiilllllld Its fun, but it's waay to expensive and also you need alot of crit so it works, go for it when you are extremly fun and feel like killing the enemy adc with 1 Q

Ahri

Medium

If she is level <6 and got her ult up, throw your (5) E on her when you jump in so you have time to kill her without her jumping around like a fox on LSD.

VS

Alistar

Hard

Pretty much the same as Leona.

VS

Amumu

Medium

He got a lot of CC that can be annoying teamfights

VS

Annie

Easy

Just wait until her stun is down, then 1 shot her. Care if she got Zhonyas!

VS

Cho'Gath

Medium

He's not really dangerous but you cant kill him because of his tankieness and his silence - Knockup is reaaaaaally annoying.

VS

Elise

Medium

Did you ever got stunned from a spider while ulting? No? Trust me... you're gona go apeshit if this happens. BUT if you dodge it, she's an easy kill.

VS

Fiddlesticks

Hard

A good fiddlestick will make your live difficult. He's a nightmare in teamfights, and when you jump in he can silence and fear you. If this happens you are dead.

VS

Graves

Medium

He's an asshole, if you are not fed enough, or he is fed, he can just turn and kill you.

VS

Irelia

Hard

Seriously, fuck this champ. Irelia is broken in my opinion. You cant kill her unless you are insanly fed or completly full build. But still, be very carefull because she can stun you atm you deal 1 damage and then rape you with her true dmg. The only thing that you can do against her, is shut her down early on... and just outdamage her.

VS

Jarvan IV

Medium

Try to ward his jungle, you can counterjungle him really hard. If you see him doing a camp, wait for him to use his E+Q and then engage on him, he cant do anything against you. Lategame you need to take care of his ult, cause it can fuck you up really hard.

VS

Jax

Hard

You have to camp is lane, otherwhise he can win the lane and win the game. As soon as he get 2-3 items you cannot kill him anymore.

VS

Jinx

Easy

I love playing against Jinx because she cant really get away from you. When she throw out her chompers, you can just walk around because you got so much movespeed.

VS

Kalista

Medium

Skill dependent. If you Jump in, you have to throw your (5) Bola at her so she gets rooted and cant kite you. If you hit it, you can kill her without any problems.

VS

Kha'Zix

Easy

Kha'zix is not that hard. If he gets ahead he will be able to kill you when you are isolated.
If this is not the case you can pretty much always 1v1 him.

VS

Lee Sin

Medium

Lee Sin is a bit tricky, once he is ahead you're gona have a hard time. 

He will probably try to counterjungle you early on. 

Ask your lanes to ward your jungle so you can stay safe against him. 

If you are stealthed, dont stay near him because his E will reveale you.

Also try not to jump anywhere near him, he will just kick you away and your engage is denied. Besides that you can 1v1 him anytime besides early game.

VS

Leona

Hard

Its really easy for her to stun and exhaust you. If she does this correctly, when you jump in, you got a huge problem.

VS

Master Yi

Easy

Invade his jungle 24/7. Buy a ward or 2, ward his jungle and kill him over and over again early on, then snowball the shit out of him.

VS

Nidalee

Medium

You can counterjungle her all day long. If you see her first, you will kill her (unless youre not in the jungle), because she cant escape you through the bushes. But you need to take care of her traps because it will stop your ult and also gona tell the enemys where you are.

VS

Nunu

Easy

He cant counterjungle you, unless you didnt ward well. If you ward your jungle, then its your turn to counterjungle him, because you win every 1v1 against a nunu. Its a bit tricky but if you learn how to ward your jungle, you can win easy. Smite wolves and/or KFC Chickens for vision and vision clear.

VS

Pantheon

Medium

It is pretty simple, early on, if he invades you, he can kill you if he times everything correct. But as soon as you have the jungle item complete, you will be stronger in a straight up 1v1. 

Try  to autoattack before using Q so his passiv will not block your whole damage.

VS

Rammus

Hard

In a teamfight he will be an annoying mofo. Try to always stand away from this guy because when he taunts you, you are pretty much dead.

VS

Riven

Medium

This is Medium to hard i think. The one that is more fed will win. But if you are even and the Riven is aware, she can turn around and rape you when you try to 1 shot you.

VS

Taric

Medium

His stun can be pretty anoying when he times it correctly.

Try to wait until he used it and then have fun raping his ADC.

Your core consists of armor pen, so the armor he give to his ADC is not gona make a big difference.

VS

Thresh

Medium

A good Thresh can denie you pretty hard with his flay and hook. Try to wait until he used his spells before going in.

VS

Twisted Fate

Hard

He's an easy kill in a 1v1 scenario, but his ultimate is a direct counter to yours.

VS

Vladimir

Medium

If you time it wrong, he can pool at the right moment and negate your burst and "surprise effect".
