Change unit base damage?

[TheDamien]

I know this is possible, it is used in the HeroCraft map.

I need to know how to, without using upgrades or stat changes, change the base damage of a hero. I'm guessing there is no "SetUnitBaseDamage" function, but is there an item power up ability or such that can achieve this?

Edit: Oops, guess I didn't search vigorously enough.

If you havn't already found out, you can use one of the morphing abilities.

Why not use upgrades?
You dont want the Damage icon to show the level of the research? thats not a problem to remove...Or you want to "undo"? Oh, ok
Item permanent damage gain as in a tome
