Read from Sion's seat: which stage windows this plan plays for against Tahm Kench.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Tongue Lash hits the first unit in its 900 line and slows — the stun needs three An Acquired Taste stacks, so count them before charging in the open. |
| Level 2 | Even / skill | Your W-shield comes online and turns his auto-trade against him; detonate it during his walk-up and the magic burst outpaces his grey-health conversion rate. |
| Level 3 | Sion | Full kit at level 3 lets you combo Q knockup into E armor-shred before his grey-health can cover the burst — force this trade when he steps forward. |
| Levels 4-5 | Tahm Kench | His grey-health passive absorbs short trades efficiently and his Q stun punishes obvious charge attempts — farm safely and charge Q only from fog angles. |
| Level 6 | Even / skill | Unstoppable Onslaught forces a binary choice: eat the knockup or spend Abyssal Dive; either outcome leaves him without his defensive CD for a full Q-E follow. |
| First item | Sion | Heartsteel HP compounding makes your W-shield enormous and your zombie passive a genuine threat — sustained trades and brawls go decisively your way now. |
| Two+ items | Even / skill | Neither of you has a decisive damage advantage late; it splits on execution — your zombie passive and HP wall against Devour pulling a teammate out of the fight. Win the side lane. |
Level 1 is quiet — his Q tongue lash has about 900 range and a reliable slow into stun, so do not try to stand still and charge a Q in the open unless you are behind the wave. He cannot kill you at level 1, but he can interrupt a visible charge by simply walking into tongue range and pressing Q. Farm at Q-tip range and let him push. At level 2 your W-shield comes up: detonate it during his auto-trade to win the HP exchange, since his grey-health passive needs time to convert back and you are already dealing magic burst on top of your autos. Level 3 is your first real opening — the full Q-E combination shreds his armor and the knockup lands before he can use his W to dive underground, because Abyssal Dive has a 0.6-second animation you can interrupt mid-charge-up by committing when he steps forward. Hit that stun and detonate W immediately: the combined burst and shred outpaces his grey-health padding in a single trade window.
