Well... there is two ways: One: If the unit has a actual selectable Attack 2 animation, that will usually be "attack,slam" if using spell animations. Buuut most units DOESENT have as such animation, and any attack animations on such units are made to be random. (even though i am pretty sure the abomination has one) Two: You need a Jass/vJass trigger. And that i am unable to help with =(
