Prominence 2 on a server: what to know
Prominence II: Hasturian Era is a Fabric 1.20.1 RPG pack; 4.1.3 (8 October 2026 on CurseForge, with a Server pack for v4.1.3) came out after the 4.1.2 release the facts above were read from. Its official hosting guide says the server pack is only on the CurseForge website, under Additional Files for each version, that it works with Modrinth clients, and that it contains a HOW_TO_RUN.md with the start steps and RAM settings. Don't build a server from the Modrinth .mrpack instead: on 4.0.x that crashed the server whenever a player joined because FTB Quests was missing, and a maintainer's answer was to use the CurseForge server pack.
The guide sizes servers at 8 GB for 3 to 4 players plus 1 GB for each extra player, suggests scheduled restarts and backups for larger communities, and offers a free listing on the official Prominence II server browser.
Watch out for
- The 4.1.3 changelog says Bumblezone and Deeper and Darker will be removed in two or three updates, taking their blocks and dimensions with them, so warn players before they build there. Source.
- Hostile mobs can gradually stop spawning on 4.1.x worlds; the 4.1.3 changelog says the team is working on it and expects a fix in the next update. Source.

Prominence 2 server files
Yes, on CurseForge. Modrinth has no separate server pack for Prominence 2, but the authors publish one on CurseForge: Prominence™_II_Hasturian_Erav4.1.2_server_pack.zip, for Prominence™ II Hasturian Era v4.1.2 (October 1, 2026). That's the same version Modrinth has.
How much RAM does a Prominence 2 server need?
| Players online | RAM | DSN plan |
|---|---|---|
| 1–3 players | About 8 GB | Premium (8 GB) |
| 4–8 players | About 8–12 GB | Heavy (12 GB)Premium (8 GB) can do at the low end of the range. |
| 9–15 players | About 13–19 GB | More than 12 GBBigger than our biggest plan. |
These follow the authors' own advice, from the fewest players in each row to the most. The pack's official hosting guide recommends 8 GB for 3 to 4 players, plus 1 GB for each extra player.
By this estimate Premium (8 GB) can run a small group. Our pick below, Heavy, leaves room for more players and for the pack growing with updates.
With 9–15 players, Prominence 2 can need more than 12 GB, which is more than our biggest plan. A lower view distance and a pre-generated world help it fit; past that, a host with bigger plans is the better choice.
Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx10500M on 12 GB. Fabric 1.20.1 takes it in the java command (-Xmx), usually in the start script. RAM guide.
