First of all. Try it before you knock it. Starting with Boots for the movement to Help with early lane ganks, moving onto Bloodthirster To start getting them stacks up and also the lifesteal helps keep you on lane to farm more gold. Then Go for Last Whisper to be able to be reasonable damage to higher Armored Champions. Then start getting Ghostbalde for More Armor Pen and Also The cooldown Reduction, This means you can active the Blade to get that extra bit of Speed increase to catch enemies Fleeing from fights and also be able to Use Ki burst more to Keep him stunned for more potention Damage to be done. Then get Nashor's For more Cooldown Reduction and Also a Boost to attack speed. Then finally Finishing With Trinity For the Chance to Slow with hits, More Crit chance and Also run speed. This makes Fleeing Champions chances to get away very thin as you can keep up and keep Stunning with Ki burst While Taking chunks of their health away at a time.

Buff Wise, Getting the Buffs around level 10 will help you out alot, And remember Even though Riven is not a Mana hero the Cooldown Reduction also Helps with Ganking and Overall Teamfight's But only get it if someone on you're team does not need it as your Cooldown times will already be Very low If you Play smart and do not Dive Towers ETC.

This build also makes it easy for Riven To do Backdooring and Full on Lane pushes since her Combo Will kill a Creep lane in seconds and if need be, Auto attacking will also kill creeps fast if you need to health up.

This is my First Posted build so i hope you liked it, Ive done this build many times and It always seens to work as i end Games with about 15 Kills 3 Deaths and Round 20 Assists since Riven has a good amount of Splash damage from her moves. Thanks again. :)
