a collection of reverse engineered data concerning damage interactions in League of Legends
This page is the source code repository. You might want to view the nice page here instead.
THIS SYSTEM IS A WORK IN PROGRESS. It does NOT claim to be perfect, BUT it should be pretty close.
This is all the result of human research. We're usually pretty good, but with a couple hundred thousand unique interactions possible, there's always room for errors.
Sometimes things also get stealth changed, which can take a while to be found. You should always test to confirm things before risking your ranked games.
If something seems missing, nonsensical, or wrong AND YOU CAN PROVE IT then please submit an issue HERE with details.
