Sion LoL Stats, Builds, Counters and Synergies

RiftMind tracks Sion champion stats by role, including win rate, pick rate, builds, counters, matchups, and synergies for League of Legends draft analysis.

Updated 2026-09-20. Data is current for LoL patch 26.18 (all regions, low elo and high elo).

How RiftMind calculates these stats

RiftMind calculates these statistics from Ranked Solo/Duo match records filtered by patch, region, rank scope, champion, and role.

Champion role, build, rune, and item summaries use patch-specific aggregates, while counter and synergy pages compare observed results with role-adjusted expectations over a rolling patch window.
