Hiiiii, this is my first build so please be gentle. This is my riven build and as you can see, you get a lot of life steal on this beast. Not only is she super op when she gets this build, she also resembles Cloud from FFVII.

Well the items might get a bit confusing, but you basically build bloodthirsters. Why? because you will destroy anyone with these items. You will never die when you're playing this beast. Get to really low health? NO PROBLEM. Go to jungle and beat some mobs you'll be back to full health in no time. Since the life steal on this build is so great, you will lose health because she's just so OP with these items. But don't worry, you'll also gain health from the blood thirsters too.

Oh yeah, if you're wondering why there's six bloodthirsters in this build, its because you sell your boots once you have enough money for a sixth bloodthirster. Which shouldn't be long because you'll be fed so badly in less than 20 minutes into the game.

This is my preferred skill sequence. I usually like to max out valor first, ki burst second, and then broken wings last. Valor will make you even more invincible while ki burst and broken wings will just devour your opponents like candy. Not to mention the animation for valor looks amazing.

Pros-
Life steal
Life steal
Life steal
Life steal

Cons-
When you're fighting in a team, because your team mates will only lower your chances of getting a pentakill
Other than that, nothing, you can never have too much life steal.

NO TEAM WORK IS NEEDED. YOU'RE SUCH A BEAST THAT YOU CAN TELL YOUR TEAM MATES TO SIT AT BASE. Then after you win, you report all of them for afking.
