How the math works

Base = scaling stat × skill ratio. Most hits scale with ATK. Some use Max HP or DEF.
DMG bonus = 1 + all DMG% boosts added together (element, universal, buffs, skill type).
Crit: crit hit × (1 + CRIT DMG). Average × (1 + CRIT Rate × CRIT DMG). CRIT Rate stops at 100%.
Enemy DEF = (100 + your level) ÷ ((100 + your level) + (90 + enemy level) × (1 − DEF shred) × (1 − DEF ignore)).
Enemy RES = 1 − RES. Below 0 RES the gain gets smaller: 1 − RES ÷ (1 − RES).
Final DMG and DMG taken are each their own multiplier.
Game data from everness.info. The DEF and RES rules come from player testing, not the game makers. Treat results as close estimates.
Not automatic: Esper Cycle reactions, stacking passives and most conditional effects. Add active ones in Fight buffs.
