Looking for who counters Sion, or which champions Sion beats in lane? The sample
matchups below show where Sion tends to over- or under-perform versus specific opponents in
aggregated high-ELO League of Legends games. Use it as a quick counter-pick reference, then let
Mejais apply the same idea live in your own draft.
Percentages are Sion's sampled win rate in that matchup; the value in
brackets is the swing versus Sion's overall sample win rate. Pairings with very few games are omitted.
