A lot of her attacks and different stolen magic types affect concepts, and she's pretty quick to use them. But I doubt most of them would be a oneshot even then. There is conceptual detonation; Observer can turn anything she touches into a bomb that will blow them up from the inside out, and given that she's an abstract being that disperses herself across a great range...

And if Observer gets pushed too far but not incapacitated or killed, she'll just pull out Terminal Null, an inner world that reverts all actions to 0, prevents any causal or temporal progression, and renders all concepts meaningless, destroying the basis of magic.
