I want to keep this guide short and simple.
Please, don't take this guide too seriously, I just wanted to provide different way to build Riven instead of this Triforce guides.
So here ya go mon!

For runes, I go for Armor Penetration Marks providing nice early auto-attack dmg.
Yellow armor runes for that little extra sustain and CDR Glyphs.
Quints also ArPen.


Greater Mark of Desolation Greater Quintessence of Desolation

22/0/8 masteries, nothing to explain.

And here we come! Double Tiamat on a way!

Begin with:


On your first return you should take
or at least


... following with
or depending on how is your lane phase going.

Build to
.

Now you should start building to buff your Atma's passive a little and give you a soft cc.

After this (If opponents haven't surrended yet) you should start with your
.

Ok now hey! Listen to me. I know that they told you "Never buy Tiamat!". But screw that! Tiamat on Riven is excelent, with double Tiamat build you'll do 100% addition damage to all nearby units, because they stack! Isn't it great? Imagine!

I won't copy every spells tooltip - you can read that up.

Q: - Great movement tool, perfect for chasing/escaping. Not that powerfull on low ranks but very powerful when maxed. Little knockback at third cast can interrupt casting. However, i max this after W.

W: - Awesome AoE channeling interrupter, combo breaker and your main harrasing spell. Max this first.

E: - Less powerful gap closer, but still useful dash. Provides strong shield lategame. CAUTION: Can't dash through walls.

R: Simple spell, 20% bonus AD, increased range, nice to have
- Wind slash: Very strong finisher, however cca 0.5 casting time so be careful with aiming at enemies at full range, they can have enought time to run.

Passive: : Your TiaTiamat's best friend, boosted autoattacks. Yay!

Laning phase:

Don't try anything till lvl 3. When you have all three spells you can begin with harrasing:
Valor to the enemy, Ki Burst for stun and Broken Wings to the safety. (Don't forget to always face where you want to jump and don't place your cursor over minions). Reason why I initiate with E is that I keep Q for additional dmg if enemy does not counterattack.

Your W have very short range, so you may need to to move slightly closer to the opponent.
When is enemy on low health, press R, approach with E stun with W and pursuit using Q. Finish with R or Ingite (if you chose that over Exhaust).
ALWAYS Auto-attack between Broken wings casts THIS RAPIDLY INCREASES YOUR DMG OUTPUT (due to passive).

Early phase:

You should have completed your Atma's at this time.
Push other lanes, clear jungle. When it comes to killing enemies, Dash-Stun-Dmg.
ALWAYS Auto-attack between Broken wings casts THIS RAPIDLY INCREASES YOUR DMG OUTPUT.

Late game:

Late game is piece of cake. You should have great sustain and AD by now. Just go and win.

When slowed use your Q and E, slow does not limit those spells.

ALWAYS Auto-attack between Broken wings casts THIS RAPIDLY INCREASES YOUR DMG OUTPUT.
You can use the third Broken wing cast to disrupt enemy's ultimate.

With blue buff you can reach 40% cdr having around 4 sec stun cooldown, however always ask your jungler or other teammates.

Okay, so my guide comes to an end, I hope i didn't offend you :)
I don't mind your criticism etc :)
Hope you'll like it and good luck on the Fields of Justice.
