Is there a way to make armor reduction stackable?

Is there a way to make a trigger that for every attack you make on a unit, the unit's armor reduces by 1 and its stackable so if u attack twice the armor is reduced by 2 and after 3 seconds the armor of the attacked unit goes back to normal.

Make multiple levels of an ability based off of acid bomb and have a dummy unit cast it after setting the level equal to the number of attacks the unit has taken so far.
