Jayce vs Mordekaiser

Updated Jun 3, 2026

Overview

Use Jayce's high early lane pressure to deny Mordekaiser safe farming and force him into uncomfortable trades.
Prioritize ranged poke and wave control to prevent Mordekaiser from setting up his passive and extended trades.
This is a snowball matchup where Jayce must leverage early agency and poke to keep Mordekaiser from scaling safely.

Trading pattern

Use (Q)+(E) empowered poke to create health leads before considering hammer form all-ins.
Punish Mordekaiser's missed (E) pull by stepping forward to trade aggressively.
Avoid extended trades when Mordekaiser's passive shield and healing from (W) are active; focus on short burst trades after poke.

Danger windows

Mordekaiser is dangerous when (E) pull is up and can isolate you with (R); avoid extended trades during this window.
Jayce is vulnerable after committing hammer (Q) engage; avoid engaging without poke advantage.
Be cautious when Mordekaiser's passive shield from (W) is active, as extended trades favor him then.

Early game

Start with ranged poke using (Q)+(E) to chip Mordekaiser before he can engage with (E) pull.
Avoid committing hammer form trades unless (E) is on cooldown and poke has landed.
Keep wave pressure high to prevent Mordekaiser from establishing slow, extended trades that favor him.

Power spikes

First damage item spike: use empowered (Q) poke to pressure waves and force Mordekaiser to respect your burst.
Mid-game poke siege: set up vision and fire (Q) through (E) gate to control space before committing.
Respect Mordekaiser's level 6 (R) spike; save mobility and defensive cooldowns to avoid isolation duels.

Win conditions

Use ranged poke and empowered (Q) to create health leads and deny Mordekaiser farm early.
Convert poke advantage into wave and plate pressure to snowball lane control.
Avoid extended trades and hammer form commits unless Mordekaiser's key cooldowns are down or health lead is secured.
