One day, I didn't had anything to do. My friend was going to a boss fight called Fenrisülfr. Ao i wanted to help him. He said to me "don't go too close to him, or He will kill you instantly. I was on my favourite rex, That had some mutations, and it was my first ever boss fight. I was scared, but the fight wasn't that long. After those days, I made army with only Fenrirs.
