I counted every rune in the game: 62 total. The row with the most options turns out to be the keystone row at 17 — more than any minor slot. Only Precision and Sorcery actually offer 4 keystones.
A data breakdown of a Korean Challenger one-trick's last 15 ranked games on Gangplank, who has stacked 3.35 million mastery points on the champion alone. Essence Reaver and Plated Steelcaps are locked in nearly every game, but Aatrox and Olaf drop the win rate to 33%.
I checked ultimate mana costs across all 173 champions. Over 80% never change from rank 1 to rank 3. Only three — Darius, Kayle, and Quinn — actually hit zero mana at max rank.
Only one champion sits at 355 base move speed, only one at 315. League's base move speed turns out to come in just 8 distinct values across all 173 champions.
We tallied base attack speed for all 173 champions. Dead last is, surprisingly, the marksman Graves at 0.475 — the slowest swing in the game. The fastest is the tank Maokai at 0.8, and the entire top 10 are tagged Tank. Marksmen average slower base attack speed than tanks do.
We counted every champion's basic attack range in ddragon's data. It only comes in 19 distinct values. Caitlyn's 650 is the longest, melee's baseline 125 is the most common at 45 champions (26%), and Annie's 625 surprisingly beats most ADC ranges.
We counted how many final items each of LoL's 277 component items can become. Kindlegem looked like the top at 33 paths, but that counts duplicate IDs — the real number is 25. Ruby Crystal actually leads with 27, and only 18 components have just one single upgrade path.
All 9 summoner spells land on just four cooldown values: 15, 180, 240, 300 seconds. Flash and Teleport tie exactly at 300, while Smite sits alone at 15 — a 20x gap.
Tallied the price of every finished item buyable on Summoner's Rift. Only two hit the 3500g ceiling, Infinity Edge and Rabadon's Deathcap. The cheapest five, all at 400g, turn out to cost nothing extra to complete.
An analysis of a Korean challenger Hecarim one-trick with 5.82M mastery points, 5.4x the runner-up champion, using public match data. Runes and Spear of Shojin locked in all 15 games, and only the Talon matchup broke the streak.
Comparing base armor and magic resist across all 173 champions at level 1, MR clusters hard: 89.6% sit in just 4 values (30-33), with 32 alone covering 78 champs (45%). Armor spreads across 24 distinct values from 18 to 43. The individual gap is 2.39x for armor versus only 1.68x for MR, and the highest MR belongs to the assassin Akali (37), not a tank.
I counted Riot's own tags across all 173 champions in Data Dragon. Support stands alone on exactly one champion, Rakan. Its solo rate is 2.3%, versus 33.3% for Marksman — a 14x gap.
