Source: matches already imported for tracked Arena Legacy profiles, including everyone in those lobbies. This is a community sample, not global Riot statistics. No account names or identifiers are published here.

Window: the latest 20,000 eligible public Arena matches within 90 days, before patch and region filters. Demo and custom-queue matches are excluded. Duplicate imports count once.

Champion pick rate = champion games / all champion games in this sample. A champion game is one participant in one match. Average placement uses only the selected lobby size; lower is better.

Augment and item usage = champion games containing that pick / all games on the selected champion. Repeated copies count once per participant. Multiple picks mean percentages do not add up to 100%. Missing pick data remains in the denominator; coverage is shown above.

Augment and item panels show usage counts only. The prismatic S+/S/A bands are relative usage tiers, not a tier list, win-rate report or proof that a pick is stronger.

Complete final builds group the Standard and Boots items found together in final inventories. Prismatic, starter and unclassified items remain outside those combinations. Inventory slots do not reveal purchase order.

Read-only results are cached for 15 minutes and refreshed on a later visit. No extra match imports are started here. Fewer than 30 observations are marked as small samples; larger samples can still be biased.
