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.
