i call this spell "Heaven's Fist" for my hero monk... the problem is i dont know how to make this trigger coz im confuse.. the monk's attack the single target enemy unit in 600 range.. and make the monk slide and move to the target unit and playing its attack animation where the place he cast the spell through the place where the target it is...
well.. first make a move loop trigger ( i hope u know how, if not ask ), while making the trigger play his attack animation. when the unit gets to the target point, create a dummy to Cast the spell, and do the dummy spell thing ( i really hope u know how )
