How to calculate "less damage from.."

Let’s say I have these items:
https://www.grimtools.com/calc/p255Ro02

Here are the numbers as I see them, I wonder how to calculate the damage an aetherial will do to me?

32% less damage from aetherials
20% damage absorption when relic is triggered
24% reduced target damage, when Light of Empyrion is triggered

Not shown, but can be arranged:
phys resist 84%
aether resistance 97%, but 99% when using aetherward oil
Other resists can go from 84% to 90+%

Thank you, I’m trying to learn this.
