How to Host a Calamity RPG III: Wounds of the World Server
Calamity RPG III: Wounds of the World is a Forge 1.20.1 RPG adventure pack set in an ancient realm of dangerous structures, forgotten ruins, and boss encounters — the third installment in the Calamity RPG series, expanding its threat roster and lore. Hosting it well mostly comes down to sizing RAM for the generation load and letting the first boot finish before anyone explores.
Start with 6 GB of RAM as your floor — Calamity RPG III's custom biomes, forgotten ruins, and boss encounters all add generation and entity load on top of Forge 1.20.1 that a lighter RPG pack wouldn't need.
Import the official Calamity RPG III modpack straight from the server panel rather than rebuilding it from a client export — the RPG progression layer depends on exact mod versions and configs lining up with the rest of the series.
Watch the first boot run all the way to a clean, finished console — the pack needs to finish generating its custom biomes and registering structure and boss data before the server is actually ready.
Don't send your party in until that first clean boot is confirmed — interrupting structure or boss-encounter registration tends to leave ruins and dungeons half-built, which is far harder to fix once players have explored them.
Take a backup before any world import, Forge update, or config change — losing a Calamity RPG III world means losing the whole RPG campaign's lore progression, not just a base.
