Use Trundle's durability and sustain inside (W) to force extended melee duels against Riven's burst combo style.
Manage lane pressure to avoid giving Riven easy short trades and cooldown resets that snowball her lead.
This is a splitpush versus snowball matchup; focus on denying Riven quick kills and reaching longer fights where Trundle excels.
Trading pattern
Initiate trades inside (W) to maximize healing and attack speed, then use (E) to block Riven's escape or chase paths.
Punish Riven after she uses (Q) and (E) by extending trades where her mobility and shield are down.
Use (Q) to steal attack damage and weaken Riven's burst, forcing her to respect longer fights.
Danger windows
Riven is most dangerous when all her basic cooldowns are up, especially (W) stun and third (Q) knockup, so avoid committing to trades then.
Beware of Riven's level 6 (R) execute window where she can burst low-health targets quickly.
Trundle is vulnerable outside (W) zones and after wasting (E) without a chase or disengage purpose; play cautiously during these times.
Early game
Play cautiously around Riven's full cooldown chains and (W) stun before level 6 to avoid lethal burst trades.
Use (Q) and (W) to trade when Riven's mobility (Q) and shield (E) are on cooldown.
Avoid fighting outside (W) to reduce damage taken and healing lost against Riven's burst windows.
Power spikes
At level 6, use (R) on Riven or a durable target to drain resistances and health, turning duels in your favor; avoid fighting her during her (R) execute window.
After your first dueling item, force side-lane trades inside (W) to pressure towers and punish isolated defenders.
Respect Riven's level 6 (R) spike and first haste/damage item timing by avoiding extended trades when her full combo is available.
Win conditions
Win extended duels by fighting inside (W), using (E) to control Riven's movement, and (R) to drain her durability.
Deny Riven's short burst trades by punishing cooldowns and forcing her into longer fights where Trundle's sustain and stat steal dominate.
Use side-lane pressure after first item spike to take towers and force Riven to respond, leveraging Trundle's splitpush identity.
