Plans & pricesWhy Vault Hunters scales differently from any other pack
With most modpacks, you plan by number of players: more people, more chunks, more RAM. Vault Hunters breaks this rule, because a vault run is technically not normal exploration. On entering, the server generates a complete temporary dimension - with its own rooms, structures, mobs and loot tables. It exists for the duration of the run and disappears again afterwards.
As long as it exists, it costs memory, and noticeably so. Experience shows that a single active vault costs around one to two gigabytes. Three players entering a vault together share one dimension - three players entering three separate vaults at the same time create three of them.
For choosing a plan, this means: do not calculate with the number of players, but with the number of simultaneous vault runs in the worst case. A server with four people who do one vault together in the evening gets by with much less than a server with four people who all do their own thing.
Storage: the world grows in spurts
On disk, too, Vault Hunters behaves in its own way. The main world stays comparatively small - you explore little because the game takes place in the vaults. In return, every run creates data, and the leftovers add up over months.
Plan L comes with 60 GB of NVMe, plan XL with 120 GB. That is enough for a long-running group with headroom for your own backups. And backups matter more here than with almost any other pack: in a roguelike, all progress depends on skill and talent data, not on built blocks. If this state is lost, the run is effectively over.
Backups are self-service with us - via the backup area in the web interface or via SFTP. It does not happen automatically, so a fixed rhythm pays off. How to proceed is described in Create backups.
Updates: the point at which runs die
Vault Hunters is actively developed, and larger updates regularly intervene in the skill and talent system. Values are rebalanced, talents rebuilt, progress occasionally reset. What is an improvement in a fresh save can cost weeks of progress in an ongoing run.
This is why the rule here is stricter than elsewhere: back up before every update, and read the pack's update notes beforehand. If a run is going well, it is often the better decision to finish it on its version and only update afterwards. A version change in the panel requires a stopped server anyway - so the opportunity for the backup arises by itself.
Which plan for Vault Hunters?
The thresholds below apply to this pack - a light Vanilla+ pack and a kitchen-sink pack with a hundred running machines behave completely differently. You can upgrade at any time without losing data and only pay the difference.
| Group | Plan | RAM | Price | Why | Order |
|---|---|---|---|---|---|
| Shared vaults, 2-4 players | Plan L | 8 GB | €11.99 / month | A group in one vault also creates only one dimension. | Order L |
| Separate vaults, 3-5 players | Plan XL | 16 GB | €21.99 / month | Every simultaneous run costs around one to two gigabytes extra. | Order XL |
| Public server | Plan XL | 16 GB | €21.99 / month | An unpredictable number of parallel runs - headroom is a must here. | Order XL |
| Solo | Plan L | 8 GB | €11.99 / month | One run at a time, plus the main world. 8 GB are comfortable. | Order L |
The memory is taken proportionally from the plan via -XX:MaxRAMPercentage - you don't need to maintain a fixed -Xmx. The basics are covered in the RAM guide.
Setting up Vault Hunters on the server
- Stop the server in the web interface.
- In the guided setup, choose Forge and search for Vault Hunters 3rd Edition via the CurseForge installer.
- Under Startup, check that Java 17 is active - matching Minecraft 1.18.2.
- Start the server and wait in the console for
Done. - Create a backup before the first vault and agree on a fixed backup rhythm - progress lives in the skill data, not in built blocks.
- Fellow players install the same pack version and connect via IP and port.
Common pitfalls with Vault Hunters
The server stutters exactly when several players enter vaults
Cause: Every simultaneous run creates its own temporary dimension with its own memory requirement.
Fix: Switch to plan XL or stagger vault runs. The switch runs without data loss, and you only pay the difference.
Skills or talents are different after an update
Cause: Larger pack updates regularly rebalance the progression system.
Fix: Only update with a prior backup and read the update notes beforehand. If possible, finish ongoing runs first.
A player gets stuck at the end of a vault
Cause: The return from the temporary dimension fails when the server is under load.
Fix: The player reconnects; as a rule, they then land correctly in the main world. If it happens more often, the plan is sized too tight.
Storage fills up after months
Cause: Leftovers from many vault runs plus your own backups in the same storage.
Fix: Download older backups via SFTP and delete them on the server, or switch to the next bigger plan.
