Riven should leverage her high early agency to pressure Sylas and deny him a calm scaling lane.
Focus on using cooldown sequencing and mobility to outtrade Sylas and snowball before he completes his first item.
This is a snowball matchup where Riven wants to punish Sylas's cooldowns and avoid extended trades.
Trading pattern
Initiate trades with (E) shield, chain (Q) for burst, and follow up with (W) stun to lock Sylas down.
Punish Sylas when he wastes (E) engage or (W) heal by committing to short combos and backing off before cooldowns expire.
Avoid extended trades if Sylas still holds (E) or (W), as his sustain and crowd control can turn fights against you.
Danger windows
Be cautious when (E) is up, as his knockup can interrupt your combos and set up his trades.
Avoid committing when your (Q) and (E) are on cooldown, as your mobility and defense are significantly reduced.
Respect (W) heal window during trades; he can out-sustain you if you overcommit without cooldown advantage.
Early game
Use level 1-3 to poke and harass Sylas before he unlocks his full skirmish combo at level 3.
Avoid trading immediately after using (Q) and (E) to prevent being punished by Sylas's engage.
Prioritize short trades around (E) cooldown to avoid his knockup and sustain.
Power spikes
At level 6, use (R) to convert prior chip damage into lethal burst; bait Sylas's crowd control before committing.
First haste/damage item boosts your cooldown recovery and trade frequency; use this to pressure Sylas and contest waves.
Respect Sylas's level 3 unlock of (Q)-(W)-(E) combo and his level 6 (R) availability; hold key cooldowns to punish after his ultimate or engage is spent.
Win conditions
Snowball early by punishing Sylas's cooldowns with fast (Q)-(W)-(E) combos and use (R) to finish low-health targets.
Deny Sylas scaling by maintaining lane pressure and forcing him to use (W) defensively.
Use side-lane pressure and roam opportunities after winning lane trades to extend your lead and impact the map.
