Polarities Mod/Fleshy Capsid

The Fleshy Capsid is a Hardmode boss summon item used to summon the outside of. It is usable anywhere in the Corruption or Crimson, but if used during a Blood Moon the will be summoned instead with no biome restrictions. If you try to use it outside the world evil biome, while a Blood Moon is not happening, or while another Esophage or Hemorrphage has already been summoned, nothing will happen and the item will not be consumed. Due to requiring an Esophage drop to craft, it is only craftable after first defeating a naturally-spawned Esophage after clearing the Pestilence.
