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.

Full Calculation
Bonus true damage: 7%13〜51G

BasisIn-game text (captured 2026-09-23): 7% true damage for 3s when you strike first; uptime from the midpoint of the 20–13s cooldown; 50% for combat only

  1. 1shorter time to kill is valued as the same % more of your own health
  2. 2Median max health 630–2,422 × 7% = 44.1–169.54 health equivalent. 44.1–169.54 × 3.33G × 50% uptime × 18% (3s ÷ ~16.5s cooldown)= 13–51G
Gold on first strike: 10G each113〜173G

BasisIn-game text (captured 2026-09-23): 10 gold per proc; the bonus gold from extra damage not counted; 50% for combat only

  1. 110G × (900s match ÷ 20–13s cooldown) × 50% uptime= 225–346G per match
  2. 2Half as the mid-match average= 113–173G
  • Total 126–224G (level 1–15)
  • Match average: mean of levels 1–15 = 171G
