Check a unit's current armor?

Hi folks, i know u can get life/mana, movespeed and also hero attributes via trigger, but im searching for a way to check a unit's armor.

i already thought about storing each unit type's armor in variables, but then again, i would have to check for every buff which modifies armor.

any ideas?

There is no trigger that can return the units armor. But Dealin have made a Armor Detection System you can use

edit: it worked, used only 1 custom script for my ability. perfect :)
