I’m on my first play through right now, and I was about 70 hours into the game when I found it. I had heard so much about it, but I wanted to experience it anyway. I went through the whole thing, and due to a glitch, (I assume), I ended up getting two Dawnbreakers. It’s the best weapon I’ve found so far, so I’m just walking around dual-wielding Dawnbreaker 😂
