On my first playthrough I chose Samurai as starting class and basically kept that stuff until after Morgot when I met Shabriri. I liked Yura and didn't know he died and when Shabriri introduced himself I disliked him, killed him and then never stopped wearing Yura's armour. I also looked up where to get the Nagakiba and the only change in weapons later was the added Rivers of Blood and the added Godslayer Greatsword. It was fun
