Jayce vs Gnar

Updated Jun 3, 2026

Overview

Use Jayce's high early agency and ranged poke to pressure Gnar and deny his scaling safely.
Control lane tempo with ranged poke to prevent Gnar from comfortably farming and timing mega form engages.
This is a snowball lane where Jayce must leverage poke and tempo leads to dominate before Gnar's mega form spikes.

Trading pattern

Poke first with empowered (Q) through (E) and only switch to hammer form to finish low-health targets.
Punish Gnar's engage cooldowns, especially when (E) hop is unavailable in mini form.
Avoid extended hammer form trades against Gnar's mega form crowd control and durability.

Danger windows

Respect Gnar's mega form (R) stun near walls and avoid committing to trades when his rage is near full.
Avoid hammer form engages when (W) stun or (E) engage is available.
Be cautious of ganks during Jayce's hammer form cooldowns or after missed poke windows.

Early game

Start with ranged poke using (Q) through (E) to chip Gnar and force him to farm under pressure.
Avoid committing hammer form trades unless Gnar's engage tools like (E) hop are down.
Use wave pressure to crash and reset before Gnar reaches level 6 and mega form power spike.

Power spikes

Use first damage item spike to increase poke pressure and force Gnar to respect empowered (Q).
Respect Gnar's level 6 mega form spike with (R) and plan to disengage or avoid fights near terrain.
Mid-game poke siege with empowered (Q) plus (E) lets Jayce control lane and force Gnar to engage on Jayce's terms.

Win conditions

Win by denying Gnar farm and scaling through ranged poke and wave control.
Convert poke damage into lane control by finishing trades with hammer form only when safe.
Use tempo leads from poke and wave pressure to influence side lanes or objectives before Gnar can engage with mega form.
