I had an idea of how to do it. Give the item an ability that doesnt do anything but can target a point, self, friendly unit, friendly hero, enemy unit or enemy hero.
Then somehow detect what the ability is targeting and do a differnet effect with triggers depending on this.
How can I detect if a unit uses an item on - A point on the map - A unit - A hero - self
thx
