Full attack-speed calculation

Base in-match interval(2.7000 − 0.0800 × (15 − 1)) ÷ 1 = 1.5800 sec
Source reduction · Light 1–6 pips1.5800 − 1.5800 ÷ (1 + 23.6%) = 0.3017 sec
Source reduction · Resonance source1.5800 − 1.5800 ÷ (1 + 39.2%) = 0.4449 sec
Source reduction · Dice Tree1.5800 − 1.5800 ÷ (1 + 38.5%) = 0.4392 sec
Total reduction0.3017 + 0.4449 + 0.4392 = 1.1858 sec
Before the floor1.5800 − 1.1858 = 0.3942 sec
Final attack intervalMAX(0.0100, 0.3942) = 0.3942 sec
Seconds deducted2.7000 − 0.3942 = 2.3058 sec

Calculations retain full precision. The interface shows 4 decimal places, and levels and dice counts use integers only.

Data version: 2026-08-25 (1–6-pip Light dice combine into one source, while 7-pip Light dice form a separate source; Light and Resonance passives both start at 5%)
