Nice, very nice !

I think i've find THE build !

You get all Riven needs:

+ a good amount of AD : +300 with BT fully loaded, which is Riven need the most.
+ nice resilience, 2300 hp, +150 Armor et MRes, tenacity, and the Randuin's Omen active (for 5 seconds !!!) is really great for teamfight, where Riven is usually ... not so good.
+ very nice HP regen + mobility + cooldown reduction from defensive item ? so great.
+ this build stay is the Riven "spirit", no useless artmog who make you hit like grandma for 5500 gold ... (artma which doesn't scale at all with Riven's abilities, so what's the point ?).

The only "minus" i see is : all this stuff is quite expensive, but all items are also quite effective.

I think (and this is my point of view) it's better to get less hp and more resistance, than being a HP pot with only 50 Mres.

I prefer start with a doran's shield, i can stay a lot longer on my lane, and be very harrassing with Riven's natural hp regen + shield bonus.

Then boots + Doran's blade, or if i get enough money, boot + brut.

And the game really begin :)

+1 for this nice work !

Think this is the best Riven build, and i have tried a lot and a lot, good balance beetwen power and resilience, teamfight and 1v1.

I did click on level 6 D: o well fixed now but thanks :D

Quite nice build:)
I prefer Lucidity Boots then Mercury/Swiftness due to it's Cooldown Reduction.
It's nice you noticed that maxing Ki Burst is more profitable than Broken Wings:)
I also must say, that i feel Sheen (and later Trinity Force) i perfect for Riven as u try to auto-attack between spells anyway.
One question: Why You don't pick ulti at lvl 6? it must be a bug :)

PS. Awesome pentakill! GZ:)
