Downvoted. I couldn't even get through the entire thing without reflecting on how annoying your constant use of fart jokes, racial/sexual derogatory words, etc etc, was.

The build itself was mediocre and had some major flaws, as well. For instance, going for a cloak and dagger on Riven is an extremely bad idea. Crit chance is almost useless, as the bulk of Riven's damage through auto attacks comes from her passive. Attack speed has a similar problem, as even when Riven has 2.5 attack speed, she still can only attack in-between abilities.

Also, Frozen Mallet + Trinity Force is a huge no-no. Trinity Force costs 4000 gold, as I'm sure you're aware, and the Phage portion of Trinity Force is roughly 1300 of it. Buying a Frozen Mallet, which is technically a Phage 2.0, after buying Trinity Force, is a waste of almost 2500 gold.

Infinity Edge is, again, a sub-optimal item on Riven. Its damage is great, but the extra damage on critical hit and crit chance that the item offers are both useless stats. To fit Riven's play style, you'd be best with a Black Cleaver for armor pen in between abilities, or a Wit's End. Both offer just a little bit of attack speed. The little boost is just enough to make Riven's passive easy to use.

So, in short, try some professionalism before making a guide for the community to read. Your constant use of slang and derogatory terms for homosexuals and black people can make people uncomfortable. That's not really what you're going for when posting something online for everyone to see.
