The Plague Caller is a pet summoning item that drops from The Plaguebringer Goliath. It summons a miniature Plaguebringer that is similar to the ones spawned by the Infected Remote to follow the player.
- The miniature Plaguebringer sprite is taken from an unused asset in the code for a scrapped summoner weapon of the same name and with a similar appearance. The Plague Caller summon weapon eventually got redesigned into the Fuel Cell Bundle.
- The miniature Plaguebringer is also used for one of the Infected Remote's attacks.
- This pet was added to the Calamity's Vanities fan mod, prior to it being added to Calamity proper.
- The pet item from the vanity mod is called the Plaguebringer Power Cell. This is referenced in the Fuel Cell Bundle, which was the redesign of the original Plague Caller.
