It was based off the scythe as I actually didn't make Luna's scythe. Back in 2020, someone made a 3D model of Luna based off that boss fight from Library of Ruina, as they were modelling different people in Imby's Discord server, and I happened to be one of them. It was very surprising to me because they did it without my permission, but I was happy with it. Even got the model into VRChat... unfortunately they never gave me the model file, so... yeah.
