whosyourdaddy increases your damage to almost nearly the same as the hp of your target... it means that it will increase your damage to one shot the target...
In recieving damage.. any damage will be turn to zero..
About abilities.. No.. it will still affect you but no damage like storm bolt no damage but stun
Your problem with AI, has three reason..
You modify the ability used by the AI wrong, like manacost,cast range,,
You use the command to stun you wrong, use Order Unit -Unit x to human storm bolt to Unity Y
Or worst
You have a problem like mine,
create a dummy that the owner is the user not a computer then command it to
stun you..
So here's the answer hope it will be solved..
