I agree that in modern realities, it is not worth relying entirely on the 3rd skill. Another example related to hero skills. I attack Temple units, kill angels, their death animation plays, and then they are resurrected without animation and give me Jigguards. Why? Even after opening the unit window, there is no information on this. It turns out that this is some kind of faction skill of the Temple, which resurrects units after death! You can only find this out through experience or by asking knowledgeable people.

While I was writing the comment, I saw other comments on this issue. I agree with Ment and Waterfall; this case is an example of a player's exploratory experience
