FOR TL;DR PEOPLE, LOOK FOR THE GREEN.


Some say Riven's not good enough to tank, she's an OFFTANK only. Some fear her. This guide will show you how to make your enemies run behind their turrets. Even those new Champions, who haven't been nerfed yet, and are still over powered (in the right hands). Riven is an excellent choice for people who HATE mana, and love a swinging sword. I first began playing her when i thought LOADS of Attack Damage items was the greatest way to play her. My GOOD games usually went 7-6-5 on Summoner's Rift. After i figured out the perfect tank strategy, my games were 4-5-35. I plowed through enemy turrets, and took on any 1 vs 5 challenge, dying, but taking a few down with me.

So, I'm a girl. Video games aren't second nature to me like my guy friends. But i refused to let them help me. I slowly learned that i needed to USE runes to win games, and what runes i should use. I figured that a lot of the items i buy, aren't really magic resist. So, I choose several Greater Glyphs of Shielding, and Greater Marks of Shielding. Both give you magic resist as you level up. I'm more of a patient person, and it gives you more than what Greater Glyph of Warding, and Greater Mark of Warding would give by end game. After I was satisfied with my Magic Resist, health was an issue. Every tank needs loads of health, so we can absorb damage in team fights. I choose several Greater Marks of Vitality, Greater Glyphs of Vitality, one Great Quintessence of Vitality, and all seven Seal spots were Greater Seals of Vitality. Satisfied, I bought one Greater Quintessence of Regeneration.

Items was kind of tricky. I was stuck on my mindset that i NEEDED Attack Damage, but I knew what I really needed, was health and armor. So, i started with Doran's Shield, so i wouldn't be first blood. (Sometimes, if I'm laning with a "real" tank, I'll get a Doran's Blade, for first blood.)
Then boots. If there's a LOT of Ability Power Champions, I usually got Mercury Treads not only for the Magic Resist, but the Tenacity too. If there weren't many, or ANY, I went for Beserker's Greaves, purely to have a little bit of Attack Damage to start the game.
After a few minutes, depending on how the game is going, I'd try to hold out for a Giant's belt. 430 Health goes a long way in the beginning. If I can't afford that yet, i went for the Ruby Crystal. even 180 Health helps. I would use either one of those two items to eventually build Warmog's Armor as my third item.
For my fourth item, i chose Phage. Not only does it give 225 Health, it gives 18 Attack Damage, and a 25% chance to slow your targets movements 30%. Then eventually it would build into the Frozen Mallet, which gives 20 Attack Damage, 700 Health, and ALL Physcial Attacks reduce your targets movement by 40% (30% for Ranged Champions)(With Rivens Valor, Ki Burst, and Broken Wing's Combo, instant kill.).
By now, your team is either winning or losing, either way, i go for Warden's Mail, giving you 50 Armor, 20 Health Regeneration, and a 20% chance to slow the attackers movement and attack speeds by 35% for 3 seconds. I build that into Randuin's Omen as my fourth item. 75 armor, 25 Health Regeneration, 5% Cooldown Reduction, and a bunch of other good stuff.
Item Five, depending on how the fight was going, i would buy either another Warmog's Armor, or another Frozen Mallet.
Item Six, would be Aegis of the Legion for it's Magic Resist, and Unique Aura: 12 Armor, 15 Magic Resist, and 8 Attack Damage to all nearby allied Champions.

If the fight was still going, and you're racking up money, sell Doran's Shield and just buy another Warmog's Armor. Your health should be close to 6300 by end game, with almost 200 Health Regeneration, 200 Armor, 100 Magic Resist, and 100 Attack Damage.

TLDR; Dorans Shield/Blade : Mercury Treads : Warmog's Armor : Frozen Mallet : Randuin's Omen : Warmog's Armor : (Longest game of your life - SELL DORANS BLADE FOR ONE OF THE OTHER 4 ITEMS)

So this will be short. Bascially, you get Broken Wings first. Lots of Damage, or a little extra boost to escape. Then Ki Burst, purely for the stun, so you can Ki Burst then use Broken Wing's, and they can't get away for those few seconds. Third is Valor, for the quick dash and small shield it gives you for a short amount of time. (incase you get a little too close to the turrets. Level 4 AND 5, get Ki Burst. It's just a good idea, especially when you have a laning partner. Level 6, get your Ultimate, Blade of the Exile. After that, what ever you want basically. I would suggest a few more Ki Burst and Broken Wings, and your Ultimate whenever it pops up. Save Valor for when its the only choice you have.

Now, using your skills.... Unlike some Ultimates, Blade of the Exile is not a final blow Ultimate. It doesn't do as much damage as some people would like (Especially with a tank build) but use it first or second. It gives a great bonus that effects your Attack Damage, boosting you Ki Burst, and Broken Wings. Second, use your Valor. It gives a small shield, and a boost towards your target. Immediately after use Ki Burst. Stunning your target gives Allied Champions a chance to either kill, or seriously hurt your target. If the job still isn't finished, use your Broken Wing's for the final blow, or to secure the kill..

Blade of the Exile : Valor : Ki Burst : Broken Wing's (REPEAT with Valor: Ki Burst: Broken Wing's)

Just use Exhaust and Ignite for those slippery Champions that like to try to get away with 20 Health left. Exhaust reduces their movement, and Ignite gives a tiny Damage over Time (DoT) that could get you the kill.

BUILD HEALTH. USE KI BURST. IF YOU ARE ****ED, THEN YOU ARE ****ED, RUN AWAY WITH VALOR.

You usually won't get any kills.
