Prominence II RPG Modpack Server Guide (2026)

Prominence II: Hasturian Era, often searched as Prominence 2 RPG, is one of the most downloaded modpacks on CurseForge and Modrinth. Cinderstone Studios makes it, and it runs on Fabric for Minecraft 1.20.1. The pack turns Minecraft into a story-driven RPG with a talent tree, a leveling system, a capital city full of NPCs and endgame boss fights.

Prominence II at a glance

Checked on 2 October 2026 against the CurseForge and Modrinth pages and the official server pack.

Key Features

• A talent tree where you build your own class from 10 fates, 16 passive talents, 5 active abilities and 100 stat talents. You do not pick a fixed class at the start.
• A custom leveling system. You earn a talent point every 2 levels, and enemies scale with your level.
• Two story campaigns, The Void's Invasion and The Hasturian Era, that open up as you progress, with quests that guide you through the mods.
• The Kingdom of Vaaz, a capital city with NPCs, shops and quests that you can visit at any point. Dialogue in the campaign and in important quests is voice acted.
• Endgame gear: artifacts forged with the Molten Core and Primordial Forge armor sets.
• Mythic Challenges, timed boss fights that keep getting harder, available once you finish Chapter II of the Hasturian Era.
• Transmogrification, so armor and weapons can look the way you like without losing their stats.

Server Setup

1. Open Prominence II on CurseForge, go to the Files tab, pick a release and look under Additional Files for the server pack. It is only offered on the CurseForge website, not on Modrinth, but players with a Modrinth launcher can still join a server built from it.
2. Check the version. Not every release gets a server pack: v4.1.1 has none, while v4.1.2 from 1 October 2026 comes with its own, "Serverpack for v4.1.2". The server and every player must run the same version, so tell your players which one to install.
3. Extract it twice. The 4.1.2 download, about 1.2 GB, is a zip that holds a readme from the pack team and the real server pack zip.
4. Upload everything in the extracted folder to your server over SFTP or with the file manager: the mods, config, datapacks, defaultconfigs and modernfix folders and the files next to them, including the start scripts, install_java.sh and variables.txt.
5. Start the server with start.sh (start.bat on Windows). On the first start the script downloads the Fabric server launcher for Minecraft 1.20.1 with Fabric Loader 0.19.3, and asks you to type "I agree" to accept the Minecraft EULA. HOW-TO-RUN.md in the pack explains the scripts.
6. Use Java 17. The pack's variables.txt sets RECOMMENDED_JAVA_VERSION=17, the same Java version Minecraft 1.20.1 is built for. If no suitable Java is installed, the start script can install it for you.
7. Set the memory in variables.txt before you open the server to players. The next section explains what to put there.

Before you update a world that is already running, make a backup and read the changelog. The server pack has no backup mod of its own. The 4.1.2 notes also say Bumblezone and Deeper and Darker will be removed in about 3 to 4 updates, and their blocks and dimensions go with them.

How much RAM Prominence II needs

The server pack's variables.txt contains JAVA_ARGS="-Xmx8G -Xms8G", so Java takes an 8 GB heap as soon as the server starts. Cinderstone Studios, the team behind the pack, suggests at least 8 GB for a group of 3 to 4 players and 1 GB more for every extra player. By that rule 6 players need 10 GB and 10 players need 14 GB.

Java needs memory on top of its heap for itself. On an 8 GB plan the shipped 8 GB heap leaves no room for that, so we suggest 12 GB and keeping the pack's 8 GB heap. If you start on 8 GB anyway, you have to lower -Xmx and -Xms in variables.txt first. The pack team gives no figure for a smaller heap, so watch memory use and move up a plan if the server runs short. On a bigger plan, raise -Xmx and -Xms so the server can use the RAM you pay for, and leave a couple of GB free for Java itself. If your server starts through the pack's start script, variables.txt decides how much memory Java may use, whatever the plan size.

The prices are for our Standard plans. The plan selector on our Prominence 2 server hosting page shows Premium and the price in your region. Cinderstone's page also suggests a faster CPU once you pass about 15 players at once. That is what our Premium line is for: Ryzen 9 9950X nodes with DDR5 in the Netherlands, Germany, Poland and Canada. As on every game server plan, the CPU is shared.

Important Server Settings

Difficulty

The server pack ships no server.properties, so the difficulty is up to you. Enemies already scale with your level in this pack. Pick the difficulty your group likes and change it later with /difficulty.

Keep Inventory

Consider enabling keepInventory (/gamerule keepInventory true) for a less punishing experience, especially with difficult boss fights.

View Distance

Start at 8 to 10 and raise it only if the server keeps up. The custom world generation looks good from far away, but every extra ring of chunks costs memory and CPU time.

Mob Spawning

Do not reduce mob spawning. The mobs are part of the RPG progression.

Multiplayer Tips

• Parties come from Open Parties and Claims, which ships in the pack. The pack's own Getting Started quest says to type /openpac-parties create, then /openpac-parties member invite and a player's name, or to press P and invite people from the party screen. Support builds such as the Bard can only buff players in their own party.
• The same mod handles land claims. Press M to open the world map, right-click a chunk and choose Claim Selected.
• The pack already scales mobs for multiplayer. In Mythic Challenges a group gets up to 3 lives per encounter, and losing them lowers the Unholy Hourglass level.
• The Kingdom of Vaaz makes a natural meeting point, because everyone can travel there at any point in the campaign.
• PvP between party members stays off until every player involved turns it on with /opacpvp, as the pack's quest book explains. The pvp setting in server.properties still switches PvP off for the whole server.

Performance Notes

Prominence II is much heavier than vanilla. The 4.1.2 server pack has 364 mod jars in its mods folder, with custom world generation, extra mobs and large structures. The pack already includes Lithium, ModernFix and FerriteCore for performance, Chunky for pre-generation and spark for profiling.

Pre-generate the world before people start exploring, for example 5,000 blocks around spawn: /chunky spawn, /chunky radius 5000, then /chunky start. That moves the chunk generation load to a time when nobody is online. If TPS drops later, run /spark profiler start, let it run for a few minutes and stop it with /spark profiler stop to see what is using the tick.

World generation and chunk loading also need fast storage. Every Space-Node plan runs on NVMe.

Prominence 2 party system and requirements answers

If a party, team, or quest feature does not behave as expected, first verify that every player is on the same pack version and that the server files match the client pack version.
