Read from Cassiopeia's seat: which stage windows this plan plays for against Gnar.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Boomerang Throw reaches 1100 to your 850, so mini-Gnar out-pokes you at level 1 with one rank of Noxious Blast and no Twin Fang to answer. |
| Level 2 | Even / skill | With two of Q/E you can prime-and-Twin-Fang, but his ranged boomerang poke and hop mobility keep it a genuine coin-flip skill trade. |
| Level 3 | Gnar | Your Q-to-E poison combo plus passive move speed lets you stick through his hops and out-DPS him in an extended trade. |
| Levels 4-5 | Gnar | Miasma grounds his 22s Hop so a dash-reliant mini-Gnar cannot leave, and ranked Twin Fang chains near-continuous nukes off your poison. |
| Level 6 | Cassiopeia | Petrifying Gaze counters his Mega dive — a charging Gnar faces you, so R stuns the engage before GNAR! lands and your poison closes the kill. |
| First item | Even / skill | It stays a coin-flip even with R online — his own GNAR! AoE stun and Rage timer make the all-in window a two-way skill check. |
| Two+ items | Gnar | Late Gnar out-scales you — Mega kites your short range and one GNAR! stun bursts a bootless, resistance-less, glass-built Cassiopeia. |
Level 1 is his — mini-Gnar's boomerang (Q) and hop-reset autos chip you for free while you have one rank of Noxious Blast and no Twin Fang to punish back. Don't walk into a boomerang to last-hit; farm off the edge of your Q zone and eat the chip. Once you hit 2-3 and have Q-into-E online the math flips: prime him with Noxious Blast poison, Twin-Fang the refund chain, and your passive move-speed buff lets you stick on him through his hops.
