Another really good song from Terraria's Calamity mod. The boss that has this theme is still one of the hardest ones I've fought so far from this mod. It's incredibly difficult but very satisfying when you win. Also, I think this is my hardest solo chart so I hope it doesn't play poorly. Enjoy.
4/8: Changed the time signatures to actually follow the song (thanks Way), added some soft beatholds, a few changes to sliders, and updated difficulty according to playtesters.
