set damage? and hide hero icon ?

Is there a way to set damage of a unit during the game? If yes, how?
thanks
PS : I won't use ability/buff because this is for a dummies units. I want to set exactly the damage from the unit.

I know you said no ability, but maybe you just though "no ability that is cast onto the unit to leave a buff, like roar or inner fire". Because there is an alternative way, you can just add to the unit the passive item ability for bonus damage.

But I can't really set my damage by this way... can I?
My damage are an integer between 1 and maybe 500.

I think I could do that with a hero but there is a problem : the hero's icone at the left top corner. I would like to remove it but I don't know how. And I don't know if it his possible...

You can remove the icon permenently in the object editor.

Stats - Hide Hero Interface Icon = True

great!!!

make a 500 lvl ability ;) gl ^_^

Or, you can just make the 1-2-4-8-16-32... combination. You only need 10 abilities to have all bonuses from 1 to 512.

but there arent 10 damage bonus abilities, are there? or how would u do that otherwise?
