Hey guys ,ive just started learning riven and im using this build :D ,
Ive read many guides and watched alot of videos ,most people seam to go 
after this but ive also seen
after last whisper/ghost blade then 
and lastly 
What do you suggest on this build ? last whisper or ghost blade,im thinking of going straight into black cleaver after hydra because then i get the much needed cdr What do you riven mains use ? any advice would be nice (:
Dunkrius2g2 votesI don't main Riven but i already know a lot about her. key here is to acheive 40% cdr. Boots and a brut will do that. Last whisperer is needed for sure. And tbh, it all depends on your match up. Sometimes you will build a 
.
Her usual build will be this (Only build BC against heavy ad) and a situational item. that could be for heavy ap damage, for more LS, 
for the lulz, 
for over all def and the passive, and perhaps if ad is getting out of control, then you could go for this as well :

Dunkrius2g1 votesNo problem. Another tip for Riven is watching pro players playing Riven. Like for example BoxBox (flosd on Twitch.tv) or BRNA (usually on youtube). They have good tips and neat tricks. What i personally learned is that when you are trying to jump over a wall, it is better to use your shield along with you Q immediately to make it easier for you to jump over. u can also jump with your Q only but there is a chance that you can fail. Im sure you know this tho.
AlldaySkandi1 votesThx for the tip ! i watch alot of box box ,i learnt the combos from him (: i never get my wall hops right so i will defs try this
BeatinWarDrumz1 votesFirst of all, dont play riven lol
Second of all, I usually build BC or hydra first (depends - hydra if im ahead, bc if im behind), then the other, then youmuus, then LW, then BT or defensive item (GA). Boots t1 should be at the beginning then get t2 after first item
