This page uses a pinned Data Dragon snapshot. It is not a verification of every in-game interaction or hotfix.
Stats and stacks calculate the state you enter. Nine outputs that cannot be derived from the source require in-game values. Special copied or possessed recasts and transfer restrictions are outside full simulation coverage.
This catalog covers normal Summoner’s Rift. Excluded does not mean removed from the game. The classification and its source are listed below.
