Track: Sion's Q — Decimating Smash (10–6s cooldown). Charged = knockup. Sidestep it.
Read from Galio's seat: which stage windows this plan plays for against Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sion | Sion's charged Q (Decimating Smash) knockup and Roar of the Slayer's armour shred out-trade your single level-1 ability — concede it, you have no engage. |
| Level 2 | Sion | Roar of the Slayer shreds armour and can fire a minion through you, and Soul Furnace free-shoves the wave; two abilities cannot punish that. |
| Level 3 | Even / skill | At 3 your Q-W-E lets you bait his Q charge and release the W taunt into an E (Justice Punch) knockup — your one clean trade, even if you can't kill him. |
| Levels 4-5 | Sion | Sion's bonus-HP shields and perma-shove out-stat your weak extended trades and deny your roam tempo through Levels 4-5. |
| Level 6 | Galio | Hero's Entrance is your spike — you can't solo-kill a tank, so flag a winning lane and roam to make the lead elsewhere. |
| First item | Sion | His first tank item and Glory in Death shrug off your kit, though the Soul Furnace pop is the one thing your W eats. |
| Two+ items | Sion | Sion out-scales into an unkillable frontline whose 60-second R crosses the map — play R presence and peel, never the duel. |
Sion owns the opening: his charged Q (Decimating Smash) knocks you up, and Roar of the Slayer poke plus Soul Furnace's clear out-shove your single level-1 ability, so concede the first wave and last-hit from range. Roar of the Slayer also shreds your armour and, if it clips a minion, fires that minion through you — so don't stand behind the wave. Your one early window is Level 3 once Q-W-E is up: bait a long Q charge, sidestep or absorb it during your W charge, then release the taunt into a Justice Punch knockup.

Start Doran's Ring + 2 Health Potions and back for Oblivion Orb (≈800g) — cuts his healing. Build Stormsurge / Riftmaker (burst vs sustain — pick by comp) first, then Zhonya's Hourglass, with Sorcerer's Shoes / Plated Steelcaps.
