Calamity's Vanities/Profaned Butterfly

The Profaned Butterflys are critters that spawn in certain biomes post-Moon Lord. They can be caught using the Bug Net to be carried around in the inventory and released later, or crafted into Profaned Butterfly Jars to be placed as a furniture item. They cannot be released once crafted. The Crystal variant is found in the Hallow and the Blazing variant is found in the Underworld.
