Pawels,
I have a question or two or three....
I want to create an Invoke Death type ability, but want it to be usesable only once. I used Strangle at level 30, which did huge damage and had a high attack, but often it would only do 4/5 damage and, of course, it could be used over and over again. Would it be possible to use the dominate ability with a strangle outcome key? So, the ability can only be used once? And is it possible to set a minimum damage value?
Secondly, is it possible to downgrade abilities using your utility? That is, in patch 1.4, the Satyr gets a low attack version of Dominate, but I can't see how to do that with the untility, as it doesn't allow attack values to be set only levels, and Dominate begins at level one (which is the usual 15 attack, I assume)...I had wanted to give the Hafling Gardener (Peasant) a lower attack version of taunt.
Lastly, do you plan on making a utility for items and heroes? I ask only because this one for units is great, and makes it easy for mod makers like me to change abilities. So, it's quite appreciated 
Cheers,
bj
