A Wraith crown is too big of an investment for an assasin that might as well get discovered and end up facing the full enemy army on his own. That wraith crown will then become a nice gift to your enemy when recovered from the body of your assasin.

Generally speaking, if you have to spend more in your assasin that the value of his likely victim then you should consider investing your coin & gems elsewhere.
