How to win lane as Tahm Kench against Sion · 54.51% win rate over 1,031 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Neither champion has a threatening level-1 all-in — Sion's Q is uncharged and your Tongue Lash poke is contested evenly by his E shield-break; both sides farm safely. |
| Level 2 | Even / skill | Sion gets his W shield at level 2 which absorbs your first Devour proc, and you get your Devour but lack enough stacks to threaten a real all-in — neither side can force a kill. |
| Level 3 | Sion | Sion's full Q-W-E combo is live: a fully charged Decimating Smash into Colossus pop is his highest-damage window and he can reliably chunk you if you misread the channel. |
| Levels 4-5 | Tahm Kench | Sion has no dash and Tongue Lash is a slow-to-stun from max range — you fish An Acquired Taste stacks for free and punish every committed Q channel with a Q-into-Devour combo. |
| Level 6 | Even / skill | Level 6 is contested: your Abyssal Voyage adds global threat but Sion's zombie passive turns any kill attempt into a risky all-in trade; neither side gains a clean kill window. |
| First item | Sion | Sion's first Heartsteel compounds with his Q-W combo into a genuinely tanky threat that your Devour damage cannot burst through — he wins the sustained HP race at this spike. |
| Two+ items | Even / skill | Both champions are near-unkillable 2-item tanks, but your Tongue Lash stun and point-and-click Devour are equally matched against his Decimating Smash knockup — skirmish outcomes depend on who lands CC first. |
Sion's level 1 is almost entirely passive — he can E-poke your shield and last-hit, but his Q requires a full channel to knockup and at level 1 he usually uses it uncharged as a slow. Match that with Tongue Lash range: poke his shield away with your Q, keep An Acquired Taste stacks off cooldown, and respect that a fully charged Decimating Smash anywhere near your feet is an instant chunk. The moment he starts channeling Q, either sidestep the glow or hit him with Tongue Lash mid-channel — a slow during his charge forces him to cancel or eat the stun on release. Thick Skin converts his E poke into grey health immediately, so he is not actually chipping your real HP the way it looks on the bar.
