Riven vs Sion

Updated Jun 3, 2026

Overview

Riven aims to snowball by punishing Sion's low early agency and cooldown windows before he scales.
Control the lane tempo to deny Sion safe scaling and avoid letting him stack health freely for teamfights.

Trading pattern

Trade short burst combos using (E) shield and (W) stun when (Q) and (W) are on cooldown.
Punish Sion immediately after he misses (Q) charge or when his (W) shield is down.
Avoid trading when your mobility is spent or Sion still holds his crowd control and disengage tools.

Danger windows

Be cautious when Sion has full (Q) charge ready from fog or brush angles to avoid knockup trades.
Avoid overcommitting when your (Q) and (E) are on cooldown, as your mobility and defense are reduced.
Respect (R) long-range engage path; sidestep or break his angle before impact to prevent lethal all-ins.

Early game

Use early levels to pressure Sion aggressively while his (Q) charge is vulnerable and (W) shield is down.
Avoid extended trades after using (Q) and (E) to keep cooldown advantage against Sion's poke.
Position to dodge or bait out Sion's charged (Q) from fog before committing to trades.

Power spikes

At level 6, use (R) to convert chip damage into lethal all-ins and punish Sion's lack of mobility.
First haste/damage item spike allows faster cooldown recovery for repeated trades and wave control.
Respect Sion's level 6 (R) engage and his tank scaling from (W) stacks; avoid extended fights when he is fully stacked.

Win conditions

Snowball early by punishing Sion's cooldowns and wave control to deny his scaling.
Use mobility and cooldown sequencing to win short trades and build leads before level 6.
After (R) activation, look for all-in kills on low-health Sion, then extend pressure through side-lane skirmishes.
