Only the top rune pages Tencent publishes are counted, so the pick rate reads lower than actual and win rates and shares lean toward the top. Streamer and pro builds are the 409 Chinese builds published by Tencent (excluding those with removed items).

How it is calculated

Pick rate is the sum over champions and lanes, and win rate is the average weighted by it. The lane breakdown and "Runes on the same page" are shares of that sum. Match counts are not published, so every champion is weighted equally.

Effect values split the description range evenly by level

Assumptions Behind This ValueTap for details

Combat only: 50%

Effects that only work in combat or under a condition are counted as active half the time. The same rule applies to every rune and spell.

Survival factor

Moving faster by some % is counted as that % more effective health, since speed lets you dodge and escape. Value = median max health × the speed gain × the health price.

Move speed % as flat

Move speed % is converted to flat move speed against the median base speed of 350, then priced at the flat rate.

Champion median

Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.

Ratios use a reference build

Build-dependent ratios such as 10% bonus AD are counted against a reference build (an assumption): 0 / 1 / 2 / 4 finished items at levels 1 / 5 / 10 / 15 (linear in between), each worth the median of the finished items that have that stat (AD 45 / AP 70 / health 350 / armor 40 / magic resist 40). Effects with ratios of two or more types (AD / AP / tank: health, armor, magic resist) count only the highest type (items use their own type), since four finished items can't be four of each type. In the Build Lab's combat power, the ratios use your actual build instead.

Damage valued like healing

Damage to an enemy is valued like healing yourself the same amount, priced with the health regen rate.

Full Calculation

Enemy slow (priced as your own move speed) (4.5s)130〜446G

BasisIn-game text (captured 2026-09-23): Priced like Exhaust's slow, counting the enemy slow as your own move speed; base 15% (the +1% of bonus HP is a ratio counted against the reference build) over the 3s zone plus the 1.5s lingering slow = 4.5s, spread over a 20s cooldown; 50% for the trigger condition

115% × 56G (1% of median base move speed 350 × 16G) × 4.5s ÷ 20s interval × 50%= 95G
2Survival: +1.69% speed is counted as +1.69% effective health
3Median max health × 1.69% × health price= 35–136G
4Total 130–231G
5Ratio: reference build bonus health 0–1,400 × 1%= 0–14
6Same formula for 0–14= 0–215G
7Total 130–231G + 0–215G= 130–446G

Own armor gain (2.5s)55〜242G

BasisIn-game text (captured 2026-09-23): +35 armor (the 75% of bonus armor is a ratio counted against the reference build) for 2.5s, spread over a 20s cooldown

135 × 25G × 2.5s ÷ 20s interval × 50%= 55G
2Ratio: reference build bonus armor 0–160 × 75%= 0–120
3Same formula for 0–120= 0–187G
4Total 55G + 0–187G= 55–242G

Own magic resist gain (2.5s)55〜242G

BasisIn-game text (captured 2026-09-23): +35 magic resist (the 75% of bonus MR is a ratio counted against the reference build) for 2.5s, spread over a 20s cooldown

135 × 25G × 2.5s ÷ 20s interval × 50%= 55G
2Ratio: reference build bonus magic resist 0–160 × 75%= 0–120
3Same formula for 0–120= 0–187G
4Total 55G + 0–187G= 55–242G

Explosion magic damage 15–10070〜336G

BasisIn-game text (captured 2026-09-23): 15-100 magic damage (the 5% bonus HP ratio counted against the reference build) over the 20s cooldown, priced with the Heal formula

115–100 ÷ 20s interval × 5 × 50% uptime = 1.88–12.5 per 5s. 1.88–12.5 ÷ median base regen 8–19 = 23–66%. 23–66 × 3G= 70–197G
2Ratio: reference build bonus health 0–1,400 × 5%= 0–70
3Same formula for 0–70= 0–139G
4Total 70–197G + 0–139G= 70–336G

Total 310–1,266G (level 1–15)
Match average: mean of levels 1–15 = 766G
