Modifying a unit's stats after being created?

[:1]I'm trying to create a way to have a hero's 'pet' have 10% of the hero's stats, (or at least just 10% of the hero's damage) whenever it is created. The pet is created automatically, so there is no summoning skill. I just run into a problem of how to modify the unit's damage, is there a way to do this? I cannot remake the unit as a hero either, it has to remain a unit.|||You can't sorry.|||why cant it be a hero? .. But you can make the "Pet" Have an Inventory and then give it a +strengt Item?
