Jayce vs Sion

Updated Jun 3, 2026

Overview

Use Jayce's high early lane pressure to deny Sion safe farming and prevent his health scaling.
Focus on ranged poke and wave control to keep Sion from setting up charged (Q) angles or stacking (W).

Trading pattern

Poke first with empowered (Q) and (E), then only switch to hammer form to finish trades when Sion cannot retaliate.
Punish missed or interrupted (Q) charges by stepping forward for short trades.
Avoid extended melee trades where Sion's tankiness and (W) shield give him advantage.

Danger windows

Be cautious when Sion has (R) ready and a clear path for engage; maintain vision and positioning.
Avoid trades when Sion's charged (Q) is visible and fully charged from fog or brush.
After hammer (Q) commits, Jayce is vulnerable; only engage if Sion's key cooldowns are down.

Early game

Start with ranged poke using (Q) through (E) to chip Sion before he can charge (Q).
Avoid committing hammer form trades unless (Q) and (W) shield are down.
Use wave pressure to force Sion into passive farming and prevent his health stacking.

Power spikes

Use first damage item spike to increase poke threat and pressure waves aggressively.
Respect Sion's level 6 (R) engage by sidestepping or breaking his path before impact.
Exploit Sion's lack of mobility without (R) by maintaining ranged spacing and punishing overextensions.

Win conditions

Use ranged poke and empowered (Q) to create health leads and deny Sion's scaling.
Convert poke damage into lane control by crashing waves and taking plates before Sion can respond.
Avoid extended fights by using hammer form only to finish trades when Sion is low or cooldowns are down.

Tip: For Jayce vs Sion, read overview, trading pattern, and danger windows first for a fast Top lane check.
