In Wonder Woman, Diana takes "The Godkiller" sword with her on her quest amongst man. The sword is in a tower that contains revered and special weapons and artifacts.
we learn that the sword is not really "The Godkiller",
it was housed amongst other special weapons.
What, if any, special powers or abilities does the sword have?
Answers from the comics are fine if the sword exists there, or is a reference to a weapon there.
