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

Power Curve

Aurelion Sol is strongest late game while Kassadin peaks late game. Play around your power window.

MR Priority

Both deal magic damage. An early Null-Magic Mantle or Mercury's Treads can swing the lane. Hexdrinker is also an option for AD champs.

Sustained vs Burst

Kassadin wants to combo and disengage. Aurelion Sol wins extended trades. Don't let Kassadin get a clean rotation Ã¢â‚¬â€ force long fights where sustain wins.

Range Advantage

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

Exploit Aurelion Sol's Weakness

Aurelion Sol's main weakness: Assassins, early all-in, immobile. Play around this to maximize your advantage.

Aurelion Sol Win Condition

Stack passive, scale into infinite-range mage

Kassadin Win Condition

Survive to 16, R spam becomes uncatchable assassin
