Arena offers three augment rarities: Silver, Gold, and Prismatic. Silver augments are offered first and tend to be modest stat boosts; Gold augments arrive mid-game and shape your build identity; Prismatic augments are end-game power spikes. Each augment is ranked here by average placement — lower is better. Pick rate shows how often the augment is chosen when offered, and top 4 rate is the percentage of games it leads to a top-4 finish.
Augment performance shifts every patch. Riot adjusts numbers, and the meta adapts. The data here updates every 15 minutes from the live match crawler.
