This piano cover fully belongs to @unnamed boi. Go check out their video (   • Calamity Mod OST | Stained, Brutal Ca...  ) for the original piano transcription, sheet music and files. I'm just reuploading the cover in this format some people prefer. I'm not making any money off of this.

Stained, Brutal Calamity - From Terraria Calamity mod - Belongs to DM DOKURO. This piano cover was made by @unnamed boi.
