Data Guides
Understand champion, build, augment, and item data from metric definitions to in-game decisions.
How to read rankings without staring only at win rate
A high win rate does not make a choice correct in every game, and a low tier does not make it unusable. Read win rate, pick rate, tier, and lift together to see where a choice works and what it requires.
Read guideSample size: do not let a rare high win rate fool you
A high win rate over dozens of games is not the same as the same result over tens of thousands. Sample size, pick rate, and skill bracket help show whether a rare setup is repeatable or simply had a short winning streak.
Read guideChoosing a champion: check the shared bench, then complete the team
ARAM Mayhem does not let you browse the entire champion roster. Choose from the options dealt to you and the team’s shared bench, then balance frontline, engage, damage, and comfort within that limited pool.
Read guideReading builds: check the purchase slot before copying the item
After the opening purchase, most shopping happens when you die and return to base. Gold, death timing, and the current game all change item order, so a build table describes completed purchases rather than a mandatory script.
Read guideSummoner spells and skill order: defaults still depend on your team
Choose summoner spells for the champion’s job and your visible team composition. Start with a broadly reliable setup, then let skill points, items, and the augments actually offered shape the rest of the game.
Read guideChoosing augments: rarity, stages, and rerolls
Choose one of three augments at the start, then receive new choices at levels 7, 11, and 15 after your next death. Read rarity and stage data alongside the champion, current build, and claim conditions.
Read guideMatching augments to champions: fit matters more than tier
ARAM Mayhem is champion-centered: normal augments must fit the champion’s mechanics, skill augments modify usable abilities, and quests must still be completed. A strong overall tier does not guarantee a good fit for your champion.
