ClothierEdward's Calamity Infernum Mode Boss (Pre-Hardmode Edition)

This is a tier list I made to rank Vanilla and Calamity Pre-Hardmode Bosses in the Infernum Mode difficulty (a difficulty mode made by Dominic Karma that makes Calamity EVEN harder than it was before) based on how hard the bosses were and how much I suffered through each one of them :,).
