The Calamity Mod is the most popular content mod for Terraria. It adds dozens of new bosses, weapons, biomes and endgame progression. You need tModLoader to run it on a dedicated server.
What is tModLoader?
tModLoader (tML) is a modding framework for Terraria available as free DLC on Steam. On a dedicated server you run the tModLoader server instead of the standard Terraria server.
Installation
- Select tModLoader as the server type when creating your server.
- Start the server once so folders are created.
- Install the Calamity Mod via the mod browser or manually place the .tmod file.
- Activate it in
enabled.json. - Restart the server.
RAM and performance
Vanilla Terraria runs on 2GB. With Calamity and extra mods, 3 to 4GB is wiser. The mod adds many entities, especially during boss fights.
Server settings
In serverconfig.txt:
- maxplayers: maximum players (default 8)
- difficulty: 0 (normal), 1 (expert), 2 (master), 3 (journey). Calamity also adds Revengeance and Death mode.
- worldname: world name
- password: server password
