Question

In the series 'Game of Thrones', the White Walkers are vulnerable to which of these materials?​

Answer 1

In Game Of Thrones, White Walkers can be killed with the help of Dragon Glass and Valyrian Steel, but not with fire.

The Wights could originally be destroyed only with fire, but then the show screwed up its logic in Season 7 and said Dragon Glass, Valyrian Steel, AND Fire destroys them. But fire does not always work.
