Trundle vs Sion

Updated Jun 4, 2026

Overview

Use Trundle's medium early agency and lane pressure to force extended melee duels against Sion's low early agency and wave control style.
Deny Sion a passive scaling lane by pressuring trades inside (W) and using (E) to cut off his escape or chase angles.
This matchup is a control vs teamfight scenario where Trundle aims to splitpush and punish Sion's tankiness with (R).

Trading pattern

Initiate trades inside (W) to leverage healing and attack speed, using (Q) to steal attack damage and weaken Sion's damage output.
Place (E) to block Sion's escape or to disrupt his charged (Q) path, forcing him into unfavorable positions.
Use (R) on Sion after he builds some tankiness to steal resistances and health, turning extended fights in your favor.

Danger windows

Beware of Sion's charged (Q) knockup, especially from brush or fog angles; avoid predictable positioning.
Respect (R) long-range engage when he has a clear path; maintain spacing and avoid being lined up.
When (W) shield is active, avoid extended trades as he can absorb more damage and retaliate effectively.

Early game

Start trades after level 2 when (W) is available to maximize healing and movement advantage.
Avoid fighting outside (W) as Trundle loses sustain and mobility, allowing Sion to punish with his (Q) or (E).
Use (E) to trap Sion when he tries to engage or escape, especially before level 6 when his (R) engage is unavailable.

Power spikes

At level 6, use (R) on Sion to drain his health and resistances before committing to extended trades.
After your first dueling item, force side-lane trades inside (W) to pressure towers and punish isolated Sion.
Respect Sion's level 6 (R) engage and charged (Q) from fog; sidestep or break his engage path to avoid knockups.

Win conditions

Force extended duels inside (W) to maximize healing and stat steals, denying Sion safe scaling.
Use (E) to pillar and trap Sion, preventing his escape or disrupting his engage, especially post-level 6.
Apply side-lane pressure after winning duels to take towers and create map pressure, leveraging Trundle's splitpush identity.
