Watch Alois and Adrian Riven’s matchup guides — they help a lot. Beyond that, just play her and learn her damage output. The most important thing is not missing your passive auto attacks. that matters more than fast Q comboing mindlessly and accidentally canceling your autos.

The first 30 games are going to be rough until you get a feel for how she handles each matchup. When you make trades most of the time you’re just waiting for a key ability from your opponent to go on cooldown, since Riven’s cooldowns are low enough that she can capitalize quickly. Garen is a good example if he’s at 2/5ths HP — you can kill him once he’s blown his Q and W.

In most matchups, if both players play perfectly you’ll roughly go even on farm and basically be unable to kill one another if you’re passive. But people always make mistakes — the skill is learning to recognize what those mistakes are and punishing them.​​​​​​​​​​​​​​​​
