Heimerdinger vs Sion

Updated Jun 3, 2026

Overview

Control the lane by establishing turret zones early to punish Sion's melee approach and limit his waveclear effectiveness.
Prioritize lane pressure to deny Sion safe scaling and prevent him from stacking health and setting up engages.
This is a control versus teamfight matchup; maintain turret control to disrupt Sion's engage and scaling.

Trading pattern

Let turrets define trades; use (E) to stun Sion when he commits to last hitting inside turret range.
Layer (W) and upgraded abilities on trapped Sion to maximize burst and zone control.
Avoid trading when turrets are cleared or (E) is down, as Sion can engage more safely then.

Danger windows

Be cautious when (Q) is charged and ready, especially from fog or brush angles; avoid walking into obvious charge paths.
Respect (R) engage when he has a clear path; keep turrets positioned to punish or deter his approach.
Avoid overextending without vision, as Heimerdinger's low mobility makes him vulnerable to ganks and Sion's follow-up engages.

Early game

Start by placing turrets to control the wave and force Sion to farm under pressure.
Hold (E) to punish Sion's attempts to engage or walk into turret zones, avoiding wasting it on poke.
Avoid pushing without vision to reduce vulnerability to Sion's engage or jungle ganks.

Power spikes

At level 3, use full turret, (W), and (E) combo to punish Sion's melee approach and prevent his health stacking.
At level 6, choose the (R) upgrade that best counters Sion's engage or bolsters turret control to deny his long-range initiation.
Respect Sion's level 6 (R) engage by maintaining spacing and turret zones to interrupt or deter his charge.

Win conditions

Maintain turret zones to force Sion to farm under pressure and punish his melee attempts with (E) stun and upgraded abilities.
Deny Sion calm scaling by controlling wave state and forcing him to take short trades inside turret range.
Use upgraded (R) abilities to deny dives and win objective setups by maximizing zone control and burst damage.
