How to win lane as Nautilus against Sion · 46.85% win rate (1,319 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Dodge his Q — Q-hook into CC, out-trade his early.
Track: Sion's Q — Decimating Smash (10–6s cooldown). Charged = knockup. Dodge it.
Read from Nautilus's seat: which stage windows this plan plays for against Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both of you are weak level 1 — your passive root keeps auto-trades even, but he has no all-in either, so it's a wash. |
| Level 2 | Even / skill | He can charge Q for a knockup that cancels your Q pull, but neither of you has full kit yet — skill window. |
| Level 3 | Sion | At 3 Roar of the Slayer cuts your armour and slows at 800 range, and Soul Furnace shields then detonates — he owns short trades. |
| Levels 4-5 | Sion | Soul Furnace plus armour-shred poke out-trade your auto-burn, and a charged Decimating Smash stuns you out of the pull. |
| Level 6 | Sion | Your R knockup feeds his zombie passive — killing him costs you the trade, and his charged Q out-CCs your follow-up. |
| First item | Sion | His HP and shield stacking on first item outpaces your flat tank damage, so your all-ins stop killing him. |
| Two+ items | Sion | Full tanky Sion with a max-charge Q knockup simply won't die to your CC chain — you're reduced to peeling, not dueling. |
Level 1-2 is your only flat window, and even then it's a coinflip — your passive root into an auto is fine, but a charged Q knockup interrupts your Q pull mid-cast and turns your engage into his. Don't walk into auto range to throw a Q he can answer with E shield-break and a W detonation. Last-hit at range, save Q for when his Q is empty, and accept you have no kill threat here.
