Does anyone know the formula for calculating the damage reduction and absorption of Wrath?

Let's say an Orc unit A has 1000 HP and 70% damage absorption, and a rage bonus of 500 units. Then, we can consider 2 scenarios: 1). Physical attack with a calculated damage coefficient of "attack-defense", where 1000 units of "pure" damage are dealt (dmg). As a result, the rage is completely removed, and 0.7 * 1 of the damage is blocked = 350 dmg, so the final damage is 1000-350 = 650 dmg, leaving 350 HP. 2). Magical attack: let's say "Lightning" deals 1000 dmg to a unit with the same characteristics. The "Defense" parameter is not taken into account, and the damage will be calculated in the same way. Artifacts and abilities can reduce the effect of the spell, but in this case, the calculation will be complicated by an additional parameter, but it will not significantly affect the overall picture. Good luck!
