This is my first guide so if any of you can tell me how to add the item pictures that would be great. Due to her nerf you want to have a lot of damage so it is still justifiable to level up W first. As you know, Riven's W has been nerfed so it does 40 less damage, and while her Q has been buffed, it is not necessairily good to level it up first as leveling it does not actually decrease it's CD. This means it does not stack too well with her passive, and considering it is not that easy to be able to hit one champion with all three Q's then it is still better to level W. To make up for the decrease in the damage for W you should buy one Doran's blade, and then buy boots. After that buy two Doran's blade. Although when you sell all three Doran's blades you lose more than 600 gold, this should be easy to redeem if you jungle a bit or gank and get a kill. Also remember to last hit. After building Doran's blade finish your Ionian Boots of Lucidity. The reason it is important to build these boots is because Riven has no mana so you want to be able to spam her attacks, and having 15% CD reduction makes this the ideal boots to have. Build Youmuu's for the CD reduction, movement speed and attack speed activation, and then start to build Blood Thirster and then Infinity Edge. You should sell your Doran's Blades as you start running out of inventory space but keep them as long as possible. Build 2 Phantom Dancers and sell your boots since the Phantom Dancers give you more than enough movement speed. The reason you build two Phantom Dancers is because with the bonus from Infinity Edge, you hit 100% critical strikes at almost 2 attacks per second. Due to your runes, Infinity Edge and your Blood thirster, most auto attacks hit 1000 + crits, meaning you do massive damage output and heal yourself 250 hp per attack (which means 500 hp per second)! For your last item consider building another Blood Thirster as the Life Steal is really good, though if the enemy has built a thornmail consider building another Blood Thirster right after the first one. This is because Thornmail reflects 30% of the damage you deal, but if you have more than 30% life steal you wont kill yourself (as you would if you didn't have any life steal). If the enemy has stacked HP with items such as Warmogs consider building Madred's Bloodrazer as it deals 4% of the enemies HP as magic damage. Sorry Cho'Gath. Remember to activate Youmuu's whenever you can and as you are not the tankiest champion in the world try not to necessairily initiate team fights but get into the middle of them when they have targeted someone else. Keep in my your ult activation, Q's and W are all AOE and you have a shield with your E so do not be afraid to jump into the mosh pit as your W is really effective for stunning and your Q hits pretty hard as well.
