The formula used (transparent)

Base DMG = Talent multiplier × Stat (usually ATK).
× (1 + DMG Bonus) × DEF multiplier (character level 90) × RES multiplier.
Crit × (1 + CRIT DMG); Average weights in your crit rate.
Amplifying reaction (×1.5/×2.0) × (1 + EM bonus + reaction bonus).

Formula per the KeqingMains Theorycrafting Library (community standard), verified by golden tests.
