Increase armor by trigger

[LiTtLe_LiOn]

I want to increase a hero's armor by using trigger
what i wanted to do is like the hero get double armor for some seconds
i think inner fire can only increase exactly the integer of armor...
and i cant found the trigger that can directly increase hero's armor
can any one help please?

Turn the item armor bonus into a unit ability and then when the unit uses their ability add that ability to them and when its done remove it.
However, I dont think there are any percentage bonuses to armor.
