Hello

A simple build i think works very well with riven, great DPS great mobility and great survivability

Masteries and runes aren't final, i need to think further about those, so this is mostly item build. Please add feedback about runes and masteries in order for me to perfect this guide.

A couple of possible item changes in this build are :
Frozen Mallet for Infinity Edge - More mobility More AD Sheen Effect which becomes really good late game.

Frozen Mallet for Black Cleaver - Third B.F Sword item, decent AD and 45 flat armor penetration after 3 hits. Also abit attack speed may help some as well.

Boots can also change for either berserkers to make up for the lacking attack speed or Ioninan to improve CDR some.

Why no attack speed on normal build ? Simply because AD is the way for improving Rivens overall performance! Every skill scales on it, so lets work on that. If you really cant live without your attack speed, go for berserkers boots and Black Cleaver instead of frozen mallet. Will work but you won't slow your opponents on hit.

I use Bloodthirster over Infinity Edge for higher AD (when farmed up) and lifesteal (25% per sword when farmed up) giving you great survivability on top of the extra AD. Having no crit items the bonus of IE is also much less useful in this build

I will max out Broken Wings first simply because it dishes out more damage than Ki Burst until you start stacking AD, which we do quite late in this guide. Besides Ki Burst does not get an increase in stun duration or anything.

Remember to place an auto-attack between each attack of broken wings to use the passive. This will make quite a difference in dps in every stage of your game.

Second i go for Ki burst to lower its cooldown and increase it's damage.

I get Valor last as its only useful for the mini-dash until you start stacking AD, getting the 2 bloodthirsters so late, we don't want this skill early.

Ghost and Exhaust, simply to never lose your target and never get surprise ganked.

You are an offtank, not a main tank. Your resistances sucks pretty big time, your job is therefore in group fights to go in after your tank and take down their carries and squishies. do it fast and effiently, then support your team on their tougher nuts.

I'm Sorry for the lack of code and fashy stuff, i simply have no clue how to use it.
I will try to edit this guide often to improve it. I hope you will go out there and smash your ennemies with this awesome and very fun-to-play hero !

Good luck all !
