I have a trigger that needs to run everytime the unit uses the ability "Reincarnation" (I am using a custom ability built off of Reincarnation, but that shouldn't have any effect). I've tried the events "unit - dies," "unit - begins casting an ability," and "unit - begins the effects of an ability." So far, not one of these events has fired the trigger. Is there a special action needed to call this event?
