How to win lane as Sion against Olaf · 49.68% win rate (2,679 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
His %HP true + R immunity — anti-heal, kite his axes.
Track: Olaf's R — Ragnarok (100–80s cooldown). CC-immune — your stun won’t hold him.
Read from Sion's seat: which stage windows this plan plays for against Olaf.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | Undertow slows and shreds armour at level 1, then Reckless Swing hits for true damage at 325 range — he wins the first skirmish before Soul Furnace exists to blunt any of it. |
| Level 2 | Olaf | Undertow is online and Reckless Swing's true damage (11s at rank 1) beats your short-charge Q tap — he wins every trade where you lack a fully charged knockup. |
| Level 3 | Olaf | A fully charged Q knockup is your one strong tool, but Undertow slows and shreds armour during the charge and Reckless Swing punishes the windup — he still edges this stage. |
| Levels 4-5 | Olaf | Olaf peaks pre-R at levels 4-5: Undertow resets its 9s cooldown when he picks the axe back up, Reckless Swing's true damage ignores your resists, and Berserker Rage heals it back. |
| Level 6 | Olaf | At level 6 Ragnarok makes him immune to disables while he keeps attacking, so your charged-Q stun does nothing — the 100-second cooldown is the only window your all-in exists in. |
| First item | Olaf | Ragnarok is up every 100 seconds and Berserker Rage gives him more lifesteal the lower he drops, outpacing your Heartsteel stacking — he still edges the 1v1 into your first big item. |
| Two+ items | Even / skill | Your Heartsteel HP pool is finally large enough that his per-auto true damage is diluted, your zombie passive forces respect even on losing trades, and the matchup reaches genuine statistical parity — neither side dominates cleanly. |
At level 1 Olaf throws Undertow to slow and shred your armour, then steps in for Reckless Swing — 325 range, true damage, and no resist of yours reduces it. Do not charge a full Q while slowed; his attack speed under Tough It Out beats your charge time. Farm with partial Q taps from max range, keep the wave slightly frozen toward your tower, and never walk over a thrown axe: picking it up resets Undertow instantly. Pop W defensively to stay healthy, not offensively to trade back.
