How to defeat the Valkyrie Queen Gna in God of War Ragnarok - give me balance difficulty

This is an extremely tough boss fight. Took me about 20 tries. I was ready to give up and just lower the difficulty. But I recommend not giving up because it’s such a great feeling once you defeat the Queen. Best advice I can give you is to focus on defense. Learn her moves and how to counter them. Attack only when you have a clear opportunity. This is a long fight and you can only afford so many mistakes as her attacks are very powerful. Best of luck and feel free to ask questions on the build I used.
