How much damage is taken

[SNOWmanx]

I have an ability that I want that I think is pretty interesting. I want to make it so whenever the hero gets hit for more damage than his attack power, it returns half of the damage.

you will have to use jass to check both the damage of the heroes, then create a dummy Damage Return skill.

And I'd do that... how?
