Favour timeline — who owns each window

StageFavouredWhy
Level 1RivenYou have one ability and no poison stacked while Riven's Broken Wings dash and auto already out-trade you — don't step into her range to farm.
Level 2RivenRiven hits her level-2 spike (Broken Wings plus Ki Burst stun) before your Twin Fang chain is online, so her all-in beats your single un-refunded E.
Level 3Even / skillFirst playable stage: ranked W (Miasma) grounds her mid-dash so she can't finish Broken Wings or E away, letting you Q-prime and chain Twin Fang — but only if you land it on her.
Levels 4-5RivenShe still edges it — if you whiff Miasma she sidesteps your Q with her dashes and all-ins on your cooldown, and a good Riven baits the ground every trade.
Level 6Even / skillGenuinely even at 6: her Conqueror plus Wind Slash execute can delete you, but your R catches her facing you for the stun — whoever lands their spell wins.
First itemRivenRiven's level-6 spike (Conqueror plus R's Wind Slash execute) outpaces your single component while you're still squishy with no MR — her all-in is lethal here.
Two+ itemsCassiopeiaYou out-scale: Liandry's plus Malignance and refunding Twin Fang out-DPS her once she can't burst you, and grounding her dash with Miasma locks her in with no MR or sustain while she melts.

Early game (levels 1–5)

Respect this lane — the data calls it HARD for a reason. At level 1 you have one ability and Riven has a frontloaded, resourceless dash kit, so don't walk into her range to last-hit or she'll Broken Wings in and Ki Burst stun you for half your bar before you can do anything back. Your only early tool is max-range Q (Noxious Blast) to chip and grab the move-speed buff to disengage; never throw it close enough that she can dash on top of you. The lane gets playable at 3 once you can rank W — Miasma grounds her mid-dash and disables her Broken Wings and E, the single best counter you have to her gap-close — but until then you're conceding levels and farming defensively.
