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.

Full Calculation
Bonus damage after mobility 10–7563〜197G

BasisIn-game text (captured 2026-09-23): Base 10–65 plus the +5 at level 5 and +5 at level 9 (both reached by level 15) = 10–75, spread over a 15s cooldown with the Heal formula; 50% for the trigger condition. The level-9 10% move speed (1.5s) isn't counted

  1. 110–75 ÷ 15s interval × 5 × 50% uptime = 1.67–12.5 per 5s. 1.67–12.5 ÷ median base regen 8–19 = 21–66%. 21–66 × 3G= 63–197G
  • Match average: mean of levels 1–15 = 148G
