Bonus damage after 3 hits

Effect

PASSIVE: Basic attacks and abilities generate stacks on enemy champions hit, up to one per attack or cast. Applying 3 stacks to a target within a 3 second period causes them to be struck by lightning, dealing them 60 - 210 (based on level) (+10% bonus AD) (+5% AP) Adaptive damage. ADAPTIVE DAMAGE: Deals either physical or magic damage depending on your bonus statistics, defaulting based on the origin of the effect. Cooldown: 20-13 seconds

SortFaded rows: pick rate under 2%

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.

Damage valued like healing

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

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.

Full Calculation

Bonus damage 60–210281〜692G

BasisIn-game text (captured 2026-09-23): 60–210 per proc over a 20–13s cooldown, priced like Ignite (damage valued as healing); 50% for combat only; the 10% bonus AD / 5% AP ratios counted against the reference build; only the higher of the AD-type and AP-type values is added Updated to patch 7.3b values (2026-10-14 patch notes; not re-captured yet)

160–210 ÷ 20–13s cooldown × 5 × 50% uptime = 7.5–40.38 per 5s. 7.5–40.38 ÷ median base regen 8–19 = 94–213%. 94–213 × 3G= 281–638G
2Ratio: reference build bonus AD 0–180 × 10%= 0–18
3Same formula for 0–18= 0–54G
4Ratio: reference build AP 0–280 × 5%= 0–14 (not counted: the AD type is higher)
5Total 281–638G + 0–54G= 281–692G

Match average: mean of levels 1–15 = 484G
