Read from Jayce's seat: which stage windows this plan plays for against Gnar.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jayce | Take Cannon Q (Shock Blast) and your orb out-ranges his Boomerang Throw at level 1; mini Gnar has no dash to dodge it, so you win the opening poke before either of you has a second ability. |
| Level 2 | Gnar | Gnar's level 2 is stronger here: a second boomerang point plus his hop lets him kite your step-up and catch the returning boomerang slow, and your Acceleration Gate isn't online yet to answer. |
| Level 3 | Jayce | Acceleration Gate (E) unlocks at level 2-3: fire Shock Blast through the gate for the full-range accelerated orb and chunk him every time he walks up to last-hit, with the Hammer-swap shred now available too. |
| Levels 4-5 | Even / skill | Genuinely even: you keep winning the mini-form poke war, but his Rage bar is filling toward Mega, so neither side can fully commit and it comes down to who manages the bar. |
| Level 6 | Gnar | Gnar's window: a full bar lets him transform, and GNAR! into Wallop can chain-CC your defenseless frame, while your R is only the stance-swap you already had and gives you no level-6 spike to answer it. |
| First item | Jayce | Your Eclipse/Manamune poke spike out-paces a still-scaling Gnar: keep the gate-Q war going and hold Hammer E (Thundering Blow) to knock his Mega all-in away the moment he commits. |
| Two+ items | Jayce | You out-duel him before he's a fully-scaled Mega: poke him down in mini form, deny the transform, and close the lane before his wall-slam stun starts out-valuing you in fights. |
Take Cannon Q (Shock Blast) at level 1 and you out-range mini Gnar's Boomerang Throw on turn one, so chip him with the orb every time he steps up to last-hit. Note you only have one ability at level 1: the Hammer-swap armor/MR shred comes online at level 2, so don't expect a full Q-then-swap combo on the opening trade. The lane really opens at level 2 when you pick up Acceleration Gate (E): fire Shock Blast THROUGH the gate so the accelerated orb out-ranges his boomerang and chunks him, and since mini Gnar has no dash he can't dodge it. Just respect the returning boomerang: it deals bonus damage and slows on the way back, so don't stand in its return line while you reposition.
