When im soloing top i usually start me entering with my E to get close to the enemey.Then use my W to stun them and right after i stun them i combo them with Q.Or you can start fight with your E then go stright to your Q combo then when you Q is done W them and walk away while they are stunned.

You can get any type of boots i perfer ninji tabi myself.If the other team does not get armor insted of the Last Whisper you can get a tanky item Warmogs Frozen Mallet ect. or another Bloodthirster.I highly recommend in Ranked Gameplay you do Build Tanky and get Warmogs ect. Also in a situation where the enemey team does not have a jungler and it is a 1v2 i highly suggest building tanky and a good way to kill them is if they try diving you stun and exaust them and use your E to gain a Shield while the turret kills them.(early game only)

Pros:

Extreamly Strong Throught The Whole Game
A Sheild Based On AD(E)
Great Abilty To Farm
Amazing Life Steal,Damage,Armor Pen
AOE Stun (W)
AOE Broken Wings (Q)
DOESNT USE MANA!!!!!!!!

Cons:

Enemeys Surrender to Fast
Enemys Complain That You're OP

I choose Flash because its a great escape tool or to catch up to your enemys to land a stun(w)pretty Much The Best summoner spell in the game!I like using Exaust because it helps you chase easily if your flash is on cooldown, or to ensure the kill.Ignite is also a good sub for Exaust

I choose those rune because it gives you the early armor pen that can give you the early give with gives you the advantage in lane. The armor and magic resist help ALOT since your build is basicly pure AD.

Basic AD masteries 21/0/9.

Riven is an amazing at Farming because she can spam her AOE skills whenever because she doesnt need mana. And if you follow this guide correctly mostly all ememey will be afrid off you so you can just farm the match away.

In my opinion i think riven is the best champion out there atm for her ability to solo top. When you use my Riven guide you won't be able to even tell that Riven got nurfed people constanly say in games why doesnt riot nurf riven ... its not riven its the build.If you really like my guide/play style and want me to make guide for a differnt charcter just msg me too. if you wanna come join our TeamSpeak all very friendly and all queue togather Adress: (vanguardgaming.servegame.com ) or visit our guild website at http://vgcg.enjin.com/ .If you ever need help or want me to teach you how to play Riven Message me on LoL Ill be Happy to give you advise/tips or anything that you need Please Give this guide a Thumbs Up and Comment :D

Important When Starting a Fight always engage with your E to give you the extra shield at the begining (and it will be off CD near the end of the fight) then use your W to stun them so you can easily land all 3 of your Q's then when they are running and/or decntly low BOOM! Ult them. or put ur Ult on at the begining of the fight for extra damage just dont use Wind Slash till the end.
