Riven's Broken Wings locks onto the champion your cursor is over at the time of cast. If you want to move past your opponent, make sure that your cursor is past your opponent as well.
Riven lacks a source of healing or strong defense and must compensate with burst combos. Lead into fights with Broken Wings and Ki Burst, while using Valor to escape and absorb counter-harass.
Playing Against Riven
Riven has a great deal of mobility but she cannot move very far with any one skill. Rooting or silencing her during her combo will greatly reduce her effectiveness.
All of Riven's damage is physical, prioritize high armor if an opposing Riven gets out of control.
Riven excels at dueling multiple melee attackers at once, as she will be on an almost equal footing damage-wise. If pairing up against Riven, don't go in as double melee until she has expended her full combo.
Autoattacking in between each Broken Wings allows for the most sustained damage as you consume Runic Blade stacks to deal extra damage
Since Broken Wings produces three Runic Blade charges, which is exactly the number that it can store, you may wish to complete it to initiate a fight with her knockup, following up with autoattacks and her other skills.
It is a good idea to learn how to autoattack cancel with Riven. This can be done by using any of her abilities immediately as the damage is applied during an autoattack. Because Riven's autoattack animation is longer than the time it takes for the damage to actually register, doing this can cut off more than a second with a combo such as Q > AA > Q >AA > Q > AA.
You must apply a new attack command in between each Broken Wings to obtain the quickest damage possible.
The best way to go about this is by autoattacking, immediately pressing Q when the damage of the autoattack is dealt, while hovering over the target. As the animation of the Q is playing, order Riven to move anywhere beside the target and immediately right click the target again. Both of these clicks should happen before the animation of Q is finished. This will allow both the animation of the Q and of the autoattack to be cancelled and will significantly increase your burst speed once mastered.
Some combinations of abilities allow for better speed. For example, any cast of Broken Wings can be used while the animation of Wind Slash is still running. The fastest way to burst down a squishy target, if you can do it without additional autoattacks, is E > R > Crescent > W > Q > R > Q > Q. Every ability in this combo will cancel the animation of the ability before it, except for the 2nd R and the 3rd Q.
Blade of the Exile lasts for 15 seconds so use it at the start of the fight instead of at the end.
Using Broken Wings in conjunction with Valor will give you small boosts of mobility as they move you forwards a bit. This is a very efficient way to move around the map, as your moves cost nothing. Broken Wings, however, allows you to click on the mini-map and use it to continue moving, while Valor will cancel your move actions.
Beware using abilities right before a skirmish, as your abilities will be on cooldown and thus be unavailable for the fight.
Make sure you test what map terrain is jumpable over, an example being: the walls separating the river and the jungle in Summoner's Rift.
Be aware that Wind Slash has a cast time and a travel time as well, so you shouldn't waste it on enemies who are just about to leave its range. Try using smartcast to save precious seconds in aiming the ability.
Wind Slash deals maximum damage to multiple opponents at or below 25% maximum health, therefore use Wind Slash to finish off enemies who are fleeing or deciding to stay despite low health.
Riven is an all-around strong champion in top solo lane due to her ability to avoid ganks with her mobility, her manaless costs, and her instant cast shield. Play aggressively and use Valor to shield your way through harass.
Broken Wings resets her autoattacks on each cast and it is useful to cut off its animations (tested under attack speed slows).
Broken Wings' dash speed is roughly equivalent to 475 movement speed. At 550 movement speed, however, simply moving is faster than using Broken Wings as a method of faster travel.
Ki Burst can be used to cancel the animations of both Riven's autoattacks and Ravenous Hydra'sCrescent active, however Ki Burst's own animation cannot be cancelled. If you like playing risky though, you can use Ki Burst during your Valor animation, as it removes Ki Burst's animation. Because of the movement however (and that's the risky part), you may not use your stun in the area you would like. Make sure you don't waste the crowd control just because you wanted to spare out one animation.
Don't use Wind Slash right away if the target is no longer stunned or knocked up, because you risk missing them if they Flash away or simply dodge it. As the range is quite long and shaped like a cone, it's easiest to hit when the enemy is not right next to you, so it may be wise to hold on to it until they try to escape.
Riven's entire kit benefits from AD and bonus AD. Building heavy attack damage items will not only help maximize her damage, but also increase her survivability through Valor'sAD scaling shield.
Riven benefits heavily from cooldown reduction as will allow her to use all her abilities more frequently. However, at later levels, Riven is likely to have at least one of her abilities available for use even without cooldown reduction, due to preferring to take her time to autoattack between casts of Broken Wings and the cooldown starting even if you delay the next two casts of it, which make cooldown reduction less needed then.
Having a way to slow the enemy or speed yourself up is mandatory on Riven.
However, Riven is very good at dealing damage while chasing as Broken Wings moves Riven forward both doing damage and giving her an opportunity to get in basic attacks without losing too much distance. The dash distance is unaffected by Riven'smovement speed, so building movement speed items are not as important on Riven as on most other melee champions.
A Frozen Mallet is good for this, since you will be using auto attacks in between abilities to maximize Runic Blade (none of your abilities will otherwise proc the slow). It also gives you health, which is a must, since Riven is squishy when stunned, rooted, blinded, or otherwise prevented from auto attacking or using her E or her Q to escape and/or shield.
Randuin's Omen works very well on Riven as while she may have four ways to dash, they are all short-ranged and Broken Wings loses damage if used fairly far-away from the enemy, and she is still a melee champion that can be damaged by ranged champions without reprisal until she gets close enough. Valor can move Riven close enough to a target to slow them with Randuin's Omen and then walk close enough to have casting Broken Wings move her into melee-range while damaging the target.
Guardian Angel is now reworked to fit AD champions, since the magic resist is gone, and AD is added. This item is very good on Riven for survivability in teamfights
Maw of Malmortius is sensible for Riven if she is fearing magic damage - the attack damage is obviously useful on her while the shield and passive works well with Valor and the life steal from The Bloodthirster in helping you survive a bit longer in a close-fight.
Riven does only physical damage, so a Last Whisper is a good item to counter the armor that should be built against you.
The Black Cleaver is also a great item on Riven, as Riven can easily stack its passive with her combos, not to mention the extra health, extra mobility and the cooldown reduction the item gives are very useful.
Stacking Doran's Blades early game provides the most cost efficient combination of sustain (though life steal), health, and AD.
Riven is great for Twisted Treeline. Her strong early game and mobility with abilities help her to dominate top lane, as well as give her great ganking ability. She also performs very well in the jungle. After netting a couple of kills early, you should be able to snowball pretty hard.
Riven has a strong early game. Be careful when laning against her. If necessary, call your jungler to gank.
Riven excels at trading with her shield, crowd control, and fairly high damage output, dishing out her damage and getting away before you even put yours out.
In lane, when Riven uses her abilities against your minions rather than yourself, she becomes vulnerable. She'll lack the damage and escape mechanisms that they provide while on cooldown, enabling you to briefly play aggressive. This is usually only advisable when she uses Broken Wings against minions, since it's her main damage source and escape ability. Of course, the more abilities she has on cooldown, the better. Take advantage of these situations as much as possible before she gets any cooldown reduction items, as her abilities have high cooldowns at low ranks.
Building armor will mitigate most of Riven's damage since she deals only physical damage.
Riven relies on her abilities and quick combos more than her basic attacks. As such, anything that can disrupt her combo (such as a silence, a stun, or even a blind) can drastically reduce her damage output.
Champions with multiple interruptions, such as Alistar, can work well as effective counters for her in a 1v1 lane.
Wait for Riven to use Wind Slash or until after Blade of the Exile has worn off before striking her. Riven has no innate sustain and the shield is her only source of damage mitigation.
Do not underestimate Riven's defensive stats, even if she is building straight damage. Valor scales off her bonus attack damage and has a considerably low cooldown late game.
Don't forget about her mobility and overextend when chasing Riven. Her Broken Wings allows her to dash up to 3 times, and her Valor allows her to dash and grants her a shield. This can create a very long gap between you and Riven.
When you are low on health, do not face Riven as her Wind Slash deals more damage the lower your health is. If you're still squishy and you know she has acquired her ultimate, do not linger around with below 25% health even to turret hug, as she can, and will, flank around to kill you with Wind Slash.
Avoid towerdiving a Riven, as her kit and mobility excels at countering any attempts to kill her under tower. For example, with Ki Burst, she can stun you, making you take even more damage from the tower.
Riven tends to snowball out of control after a kill or two. Hence try to avoid dying to her even if it means losing a few CS.
Valor has a short cooldown after she has maxed it out or has obtained several cooldown reduction items. This allows her to outplay unsuspecting opponents easily.
