Build MR — charged Q stun, dodge his E root.
Track: Swain's R — Demonic Ascension (120s cooldown). His drain. Trade when it’s down.
Read from Sion's seat: which stage windows this plan plays for against Swain.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Swain's level-1 Q bolts spread wide — step sideways so only one clips you and he can't sustain a trade with chip poke alone. |
| Level 2 | Sion | Your W-shield absorbs his Q burst and detonates for magic damage in return — Swain has no escape from your knockup at level 2 once you commit. |
| Level 3 | Sion | Charged Q knockup plus E armor shred at level 3 is a full combo Swain cannot dodge without a dash; the stun lets you convert a full kill threat. |
| Levels 4-5 | Even / skill | Swain's W bomb slow into E root can set up a dangerous Ascension window — walk unpredictably at levels 4-5 and never straight-line toward him. |
| Level 6 | Sion | Unstoppable Onslaught closes past his W positioning, and a knockup ends Demonic Ascension — the form lasts only while he drains a champion. |
| First item | Sion | Heartsteel compounds faster than Ravenous Flock — but its fragments heal him and raise his max health for good, so Grievous Wounds decides this window. |
| Two+ items | Sion | At 2+ items your zombie passive deals damage during the few seconds you reanimate — even if Swain catches you low, he pays a tax for the kill. |
At levels 1-2, Swain pokes with his Q Death's Hand bolts from short range — step sideways in the lane so only one or two bolts clip you rather than the full spread. His W Vision of Empire is a long-range bomb with a slow that telegraphs heavily; the moment you see the glow drop onto you, side-step it entirely. Your W-shield is your answer to his Q: pop it before walking into poke range, absorb his bolt cluster, then detonate it for a free chip of magic damage back. He has no dash, so once you reach level 3 and have Q charged, he cannot reliably escape — land E armor shred first to slow him, then release the fully charged knockup. His E Nevermove is a short-range boomerang line that roots on the pull-back; hug the wall side of the lane so the return arc misses you, and never walk directly toward him in a straight line.

Sion, slightly — a 52.95% win rate edge over 1,560 games; execution can flip it.
Mostly — Sion has a small statistical edge (52.95% win rate), but execution decides this lane far more than the pick does.
Not a hard counter — Sion has a slight edge (52.95% win rate), and play quality decides the rest.
Sion takes Grasp of the Undying on the Resolve tree with Demolish, Second Wind and Overgrowth, and Precision secondary (Triumph and Legend: Haste) vs Swain.
Start Doran's Shield + Health Potion and back for Executioner's Calling (≈800g) — cuts his healing. Build Heartsteel (W + passive love HP) first, then Warmog's Armor / Thornmail, with Mercury's Treads.
