Is it possible to tell if a unit is being hit with a spell? Like an "event: Unit is hit with spell" type thing. Also, if it is possible to tell who cast that spell and what spell it was?
Target of Casted Ability fires when a unit is hit or when an ability is cast? What happens when an ability is cast that has no target or can hit multiple targets?
It has 2 things: Target of ability cast (unit), target of ability cast (point), then just pick every unit within that area that is of the type the spell affects, then if it is the unit, done.
