I myself do get warmogs earlier, right after my first offensive item(Bloodthirster usually). If you go Merc treads you get some magic resistance and with the impaler you get some armour, this seems to be enough since Im not the main tank. Also, you wouldnt get facerolled by any champ with razors, there are too many variables to actually conclude that b:

Also, I dont get infinity edge usually, since I dont auto-attack much, but then again I never get a 6th item.

C'mon guys dont rate this down if one thing is bothering you or if you have a different personal preference or taste when playing Riven, its a well made guide!

stacking health doesnt make u tanky at all u will just be a big squishy target if the other team had a kog or warwick this build would not work ud get face rolled by any champ with razors

From my point of view I can say that I highly enjoy having 30% + cool-down reduction in mid-/ late game. It is what makes you a being able to use skill combos on demand as you do not have to worry about availability much...

So far it seems solid.
Can you explain me why you decided to take Warmog's Armor last as it may be late to stack it up?

No vote from me yet...

Cheers

Thanks!

I would advise against dropping warmogs, Riven does plenty of damage without youmu's. These are actually all the items I personally use. Good build man!

lol. Thats the second person that tells me Youmu's. I gotta try it.

drop warmogs add youmu's and try last whisperer its a great item for scaling into late game. =3= and i hate u.

Awesome. Tell me how it goes!

Mmm sounds good, i will try it :D

Thanks! Ill try that out!

I suggest you switch infinity edge with yomuu's ghost blade or another bloodthirster in your build. Also, I'd rather get some other tanky item instead of warmog's. You'll have better survivability by building an item with armor or mres. You do get damage from warmog's, but I wouldn't put frozen mallet and warmog's in the same build. Randuin's omen/banshee's veil also give you hp in addition to the armor/resistance, so they do increase your armor too.
Also, cooldown reduction is GREAT on her, so brutalizer's armor pen + cooldown reduction make it an EXCELLENT early item for her. You can upgrade it to youmuu's after your other core items.
