League Matchup Toolkit

League Matchup Toolkit

Matchup Notes

Keep lane, sidelane, and teamfight notes per champion matchup, plus a live enemy ability cooldown reference. Your written notes are stored in this browser.

Damage Calculator

Configure a champion's level, items, and ability ranks to see combo damage against one or more enemy champions, built from their level/items/stats too.

Backup & Transfer

Your matchup notes, rune picks, and custom tooltips live only in this browser. Export them to a file to back them up or move them to another device, then import that file there. The file isn't plain text - champion/item data isn't included either, it re-downloads automatically.
