The Ancient Wyvern - Dark Souls 3 Boss
I manage to beat the Ancient Wyvern on my first try without dying... with a little help from Knoah.
Honestly... I really liked this fight, but it could have been a lot more intense. It was definelty cinematic, but I wanted this fight to feel more perilous. I wanted the Wyvern to chase me more around the map, and use that to lead me to the win condition. As well, the win condition was poorly executed; the Wyvern just felt like it was waiting for the killing blow at that point... It didn't give a good fight for me to feel really accomplished; all it really did was look cool.
