Calamity Mod Wiki

Summoning items are items that are used to summon enemies, bosses and events. Most bosses will usually not spawn on their own, therefore requiring the player to create their summoning item in order to progress.

Most boss-summoning items can also be bought from different NPCs after they have been defeated. See Bosses for a list showing which NPC sells which item.
