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

Kassadin is strongest late game while Swain peaks mid 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.

Hit and Run

Kassadin needs to combo and back off. Don't stay in extended trades against Swain's sustained damage. Short trades, then disengage.

Range Advantage

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

Exploit Kassadin's Weakness

Kassadin's main weakness: Early game extremely weak, AD matchups, CC. Play around this to maximize your advantage.

Kassadin Win Condition

Survive to 16, R spam becomes uncatchable assassin

Swain Win Condition

R drain tank in teamfights, E root picks, soul fragment scaling
