The biomes that ''Calamity'' adds house unique enemies and bosses.<ref name=":4" /> Certain biomes are largely inaccessible until a specific condition is met, such as the Abyss, which requires special gear to traverse, and the Astral Infection, which only spawns after the Wall of Flesh has been defeated.<ref name=":7">{{Cite web |last=Petrovich |first=Erik |date=2021-07-21 |title=Terraria: Everything To Know Before Starting The Calamity Mod |url=https://gamerant.com/terraria-calamity-mod-facts/ |access-date=2025-08-24 |website=Game Rant |language=en |archive-date=July 4, 2025 |archive-url=https://web.archive.org/web/20250704140950/https://gamerant.com/terraria-calamity-mod-facts/ |url-status=live }}</ref> Existing biomes receive new structures and enemies, as well as new materials that can be used to craft various new items.<ref name=":2" /><ref name=":3" /><ref name=":7" />
Alongside the base Classic, Expert and Master modes, there are additional optional difficulty modifiers named "Revengeance" and "Death" that change enemy and boss AI and add new game mechanics. The mod adds new NPCs as well as quality of life features.<ref name=":3" />
The mod completely changes the lore of ''Terraria'', with its narrative centering around the player growing strong enough to confront the Godseeker Yharim, a central figure in its lore. Players can obtain lore items that provide background information about the world and its characters.
