Abalative Armor and Stone Construct Interplay


Abalative Armor provides damage reduction 15/- at 10th level, once the infused item has prevented damage from a single attack even if not all the damage reduction is needed, the magic fades.

Stone Construct provides damage reduction 10/adamantine. Once the spell has prevented a total of 10 points of damage per artificer level you possess (maximum 150 points) it is discharged.

If a creature has damage reduction from more than one source, the two forms of damage reduction do not stack. Instead, the creature gets the benefit of the best damage reduction in a given situation.

My question is does the damage reduced by the Abalative Armor also reduce the total provided by Stone Construct?

Apologies if this question has been asked in the past by another.
