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

Mid-Game Showdown

Both champions spike around the same time. The player who gets their first item faster wins. Focus on CS leads and smart trades to build an advantage before the mid-game.

Armor Rush

Both champions deal physical damage. Whoever builds armor first (Plated Steelcaps, Bramble Vest) gets a huge advantage in trades.

Hit and Run

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

Exploit Riven's Weakness

Riven's main weakness: Hard CC, bramble vest, falling behind. Play around this to maximize your advantage.

Riven Win Condition

Animation cancel combos, snowball lane, splitpush or teamfight

Illaoi Win Condition

Land E, force fights in tentacle zones, R in 2v1s

Kill Pressure vs Map Play

Riven typically runs Ignite for kill pressure. Illaoi runs Teleport for map impact. Riven needs to convert the combat advantage into kills before Illaoi outscales through TP plays.
