Bei so viel Kantigkeit wird ja selbst Immanuel vor Neid ganz gruen . <| sep |> Gendry explains to Arya I wish I had a flaming sword . Arya could think of lots of people she ' d like to set on fire . It ' s only a trick , I told you . The wildfire ruins the steel . My master sold Thoros a new sword after every tourney . Leaving steel swords in such intense flames destroys the sword it does not have be reforged but it must reworked to reestablish the proper ductility to hardness features . The entire sword is engulfed in flame its leather grip is burned away . When Davos mentions that the sword is blackened mess , he means the sword is no longer a functioning sword . In fact , any of the metallurgic experts on this site swill tell you , that sword was heat treated and then quenched part in air , part in soil . The sword is now a metallurgic mess . What matters most is that Melisandre first attempt was a fake and she doubled down with a second fake using a separate fraudulent scheme .
