How are champion matchup win rates calculated?

Win rates are calculated from thousands of ranked games in Emerald+ elo on the current patch. Data is sourced from OP.GG and updated regularly.

What does a 55% win rate matchup mean?

A 55% win rate means Champion 1 wins 55 out of every 100 games against Champion 2 in ranked. Anything above 52% is considered a favorable matchup.

Do matchup win rates change every patch?

Yes. Champion buffs, nerfs, item changes, and meta shifts can all affect matchup win rates. Our data updates with each new patch.

Should I always pick the counter champion?

Not necessarily. Comfort and experience on a champion often matter more than counter-picking, especially below Diamond. A 2-3% win rate difference is easily overcome by champion mastery.

What rank is the matchup data from?

All matchup data is sourced from Emerald+ ranked games to ensure the data reflects skilled play. Lower elo matchups can differ significantly.

How to Play This Matchup

Early Aggression

Jayce needs to punish Kassadin before they scale. Zone them off CS levels 1-5 and look for solo kills before first back. If Kassadin reaches 2 items even, you're in trouble.

Mixed Resistances

Jayce deals AD damage while Kassadin deals AP. Build resistances accordingly Ã¢â‚¬â€ don't stack the wrong type.

Range Advantage

Jayce has range advantage. Kassadin should look for short trades when Jayce uses abilities on the wave. Freeze near your tower and wait for jungle help or an all-in window.

Exploit Jayce's Weakness

Jayce's main weakness: Falls off late, mana hungry, no ult. Play around this to maximize your advantage.

Jayce Win Condition
