With that being said, I use the show to make assumptions about the book.and Valyrian Steel being able to kill Others in the books is a safe assumption based on last nights episode. IMO, the changes have been superficial and does not compromise the adaptation. But the easiest way to wipe out huge swaths of wights is to kill the White Walker that created them in. A popular example of it is dragonglass, which is called Obsidian by the maesters. They can be killed by being set on fire or stabbed with either dragonglass or Valyrian steel. Infact, anything that is forged from dragon-fire can kill White Walkers. Yes they have merged story lines, omitted less important aspects, and changed a few things but they have stayed faithful to the books in my opinion. Valyrian steel, being forged of dragon-fire, which is a power of the Lord of Light, can kill White Walkers, the army of the Great Other. I think HBO has done a good job adapting he story. As we know, White Walkers can be killed by Fire and Dragon Glass only. When it is all said and done, if the book is significantly different from the show, then who is to blame? As shown in the last season of Game of Thrones, one of the leaders of the White Walkers was killed by Jon Snow's Valyrian steel sword. I trust the show to use that info as they have used the published books. ItвЂ™s recognisable by its intense sharpness and light weight.

An article I read last year quoted one of the 'D's' as saying that they went through every major character and important non pov character's story arc and GRRM told them what he had planned for each character. Valyrian steel, a metal forged in the days of the Valyrian Freehold that remains sharp forever, is another way to kill White Walkers.

They sat down with him right before season 4 aired and talked about the series. This happened in the last 2 years or so.That's right. Valyrian steel, being forged of dragon-fire, which is a power of the Lord of Light, can kill White Walkers, the army of the Great Other. And they've stated, several times, that they had a second major sit down with him after it was clear the show would overtake the books.
