Same shape as the item synergy / counter pick / duo rankings + matchup tables.Sion's Bayesian-smoothed win rate when paired with this ally.Bidirectional synergy delta: avg of Sion's gain over their baseline and the ally's gain over theirs. High = both benefit from the pairing. Hover a row for the per-side breakdown.Number of games played together.

support
Sion's WR when this ally plays support. Sort ↓ Score for best synergies, ↑ for worst.
Synergy score from Sion's perspective. Per-result-set z-score (mean 0, SD 1) of the weighted composite 0.70·z(delta) + 0.20·z(games) + 0.10·z(WR). Positive = ally helps Sion, negative = ally drags Sion down. Same shape as the item synergy / counter pick / duo rankings + matchup tables.Sion's Bayesian-smoothed win rate when paired with this ally.Bidirectional synergy delta: avg of Sion's gain over their baseline and the ally's gain over theirs. High = both benefit from the pairing. Hover a row for the per-side breakdown.Number of games played together.
Win RateⓘBayesian-smoothed: (wins + 25) / (games + 50). Reliable even with small samples.

Presence by Rank
Pick / ban / P+B rates across the ladder. Rank-agnostic — the rank filter is ignored here.
↑↑Very high compared to other champions in this role

·Average compared to other champions in this role
ScalingⓘWR slope vs game length. Positive = scales well late, negative = falls off. Practical bounds: ±0.03
-0.001
Rank BiasⓘWR slope vs rank. Positive = better in high elo, negative = better in low elo. Practical bounds: ±0.036
-0.004
Worst MatchupⓘWorst lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Tail complement to Matchup Spread — captures champions punished by a small number of extremely spiky lanes that MAD averages out. Closer to 0 = no truly bad lanes (safer blind pick). Min 30 games per opponent, ≥5 well-sampled opponents.
-5.8%
Best MatchupⓘBest lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Higher = stronger counter-pick power against the right opponent. Min 30 games per opponent, ≥5 well-sampled opponents.
