3 years ago to sum up my testing insanities, elemental amps are only applied to the first attack that the builder calculates- right hand in dual wield first hit in a multi-hit ability (figaro jump +4) first cast of multi-cast sets (chaos chain)

additionally, possibly on purpose, elemental amps as part of an ability do not appear to be factored in to damage (Dark Art: Shadow Sting)
Selecting 9S with a goal of physical damage for all cases. Nothing changed if I added a wind imperil.
RHand - Air Tempest LHand - None Material - Dual Wield Wind Amplify - None 1x Phys Atk Damage - 2298
RHand - Air Tempest LHand - None Material - Dual Wield Wind Amplify - 100 1x Phys Atk Damage - 4596 (doubled from previous, correct)
RHand - Air Tempest LHand - Astraea Aurora Material - Dual Wield Wind Amplify - None 1x Phys Atk Damage - 5008
RHand - Air Tempest LHand - Astraea Aurora Material - Dual Wield Wind Amplify - 100 1x Phys Atk Damage - 7411 (~50% increase, may only be applying to the wind weapon?)
This is for King Edgar's Figaro Jump +4 RHand - Air Tempest LHand - None Wind Amplify - None Figaro Jump +4 - 27,195,930
RHand - Air Tempest LHand - None Wind Amplify - 100 Figaro Jump +4 - 27,238,226 (somewhat lower than a 100% increase, may be related to how the skill is split into three 10 hit components and a delayed jump?)
EDIT - Found another aspect of this bug (doesn't seem to happen without elemental amplify present). When swapping weapons in the 9S Air Tempest/Astraea Aurora build, the damage wasn't identical. Tried it again with different weapons after a refresh and got an even more pronounced effect: RHand - Baroque Sword LHand - Air Tempest Material - Dual Wield Wind Amplify - 100 1x Phys Atk Damage - 4971
RHand - Air Tempest LHand - Baroque Sword Material - Dual Wield Wind Amplify - 100 1x Phys Atk Damage - 5846
