Boomerang-poke — dodge his Q, poke his immobile body.
Track: Sion's Q — Decimating Smash (10–6s cooldown). Charged = knockup. Dodge it.
Read from Gnar's seat: which stage windows this plan plays for against Sion.
This is Gnar's own plan; across 2,136 pooled games the lane is leaning Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both of you are passive level-1s — last-hit at Boomerang range and just dodge any charged Decimating Smash; neither champ owns the level yet. |
| Level 2 | Gnar | Hyper's third consecutive hit plus a Boomerang punishes Sion's base HP for free, and with no dash he can't answer Gnar's move-speed burst. |
| Level 3 | Gnar | Gnar's Mini kit is fully online and Sion is still immobile — kite with the Boomerang slow and Hyper speed and he can't close the gap to trade back. |
| Levels 4-5 | Even / skill | Levels 4-5 are a coinflip: strong when Rage lines up for a Mega Wallop stun, a liability in Mini when a charged Decimating Smash knockup lands. |
| Level 6 | Even / skill | At 6 he gets Unstoppable Onslaught on 140 seconds, a map-wide charge whose knockup scales with distance; with Mega up you answer it, without it you do not. |
| First item | Gnar | Mini-Gnar's poke range lets him deny Sion's soul stacks and force Soul Furnace shields instead of farm, pulling the lane tempo his way. |
| Two+ items | Sion | Sion outscales hard — two tank items plus his base bulk shrug off Gnar's Mega burst (and his zombie keeps fighting after death), so the late game is Sion's. |
Sion can't catch you, so this is a free poke lane in Mini — auto-and-Boomerang his big base HP and step out before Roar of the Slayer (E, 800 range) answers: it slows and shreds your armour, so stacking plates is not the fix here. The one thing that flips it is a fully-charged Decimating Smash: never stand still while he winds up the Q, and never eat that knockup mid-transform. At level 2 his lack of a dash means Hyper's third-hit proc and its move-speed burst let you walk in, chunk him, and walk out for free.

Start Doran's Blade + Health Potion and back for Executioner's Calling (≈800g) — cuts his healing. Build Stridebreaker (stick + waveclear) first, then Sterak's Gage, with Plated Steelcaps.
