You took down the Valks too? I’m currently on the 6th Valkyrie in Hel. I’m playing on the highest difficulty so, yeah, it’s a bit tough.
I think the one that cost me the most was the third one and despite playing on a much lower difficulty than you, they also cost a lot but you more hahahah. The good thing about playing in that mode is that I guess the sastifacion is bigger. Good luck with Queen Valkyrie<3
