Augments
Riot’s match data does not say which augments players took, so there is no augment win rate here and none is invented. Each line pairs what the augment grants with something measured about this comp: 0 are a real placement comparison, the rest say whether the augment suits how this comp actually plays. Augments we can tie to nothing are not listed, and the app behaves identically.
