Is there a way to find affected units from like shock wave or healing wave, or chain lightening. (Without triggering the move, just a unit finding trigger etc.)
Just an idea. How about having a certain dummy for the wave spell. Instead of using the wave by the hero itself use a dummy spell and create the dummy unit to use the wave. Now you have to add every unit that enters the map to the trigger where you want to do something with the units that get hit by the wave.
[a trigger where you can add the event a Unit is damaged]. Now you check whether the damage source was done by the unit that is the certain dummy, and in case it is, perform your actions.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
