Read from Olaf's seat: which stage windows this plan plays for against Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | No dash means your Q-slow sticks his first contact and your passive attack speed wins the level-1 auto trade. |
| Level 2 | Olaf | Your Q-into-auto chunk out-trades Roar of the Slayer's armour-shred poke before Soul Furnace scales. |
| Level 3 | Olaf | Q-slow plus E true damage bursts him while his W shield is still too small to absorb it. |
| Levels 4-5 | Olaf | Axe resets perma-stick him and Tough It Out's shield covers his poke through 4-5. |
| Level 6 | Olaf | Ragnarok makes you immune to the stun on his charged Decimating Smash while you keep swinging. |
| First item | Olaf | Your bruiser-core lane pressure forces dives his immobile kit can't answer at first item. |
| Two+ items | Even / skill | From two items Soul Furnace, his HP pool and Glory in Death sponge your flat true damage — it levels out. |
Sion is exactly the immobile melee you farm: no dash to dodge your Q, so your axe-slow sticks every time and your passive ramps attack speed as you take his poke. Respect two things — a charged Decimating Smash stuns and knocks up, so trade on its 10s cooldown or bait it and step in, and Roar of the Slayer fired through a minion knocks that minion into you and shreds your armour. At 2-3, Q-slow into E bursts him before Soul Furnace is big enough to eat it.

Start Doran's Blade + Health Potion and back for Executioner's Calling (≈800g) — cuts his healing. Build Sundered Sky (sustain spike) first, then Sterak's Gage, with Plated Steelcaps.
