How to Host an RLCraft Dregora Server (2026 Guide)

Start from 8 GB of RAM as your floor, not a guess. RLCraft Dregora is a Forge 1.12.2 pack carrying both RLCraft's heavy mob/structure overhaul and Dregora's custom world-generation layer, so 8 GB is the catalog's own recommended minimum — going lower leads to chunk-generation stalls the moment players scatter across the new terrain.

Import the modpack directly from a known RLCraft Dregora build instead of guessing from a client export. Mixing a hand-copied client install with a server pack is the fastest way to end up missing server-side world-gen jars, which breaks Dregora's biome generation on day one.

Watch the console through the entire first boot. Dregora replaces vanilla world-gen with procedurally generated terrain, custom biomes, and unique dungeons, so the first startup does noticeably more chunk and structure setup than base RLCraft — let it finish fully loading before assuming it's hung.

Only invite players after that first boot has completed cleanly with no repeating errors in the log. Letting people log in mid-generation on a brand-new Dregora world is how spawn chunks end up half-generated or corrupted.

Take a backup before any world import, loader update, or config change. Dregora runs are usually started specifically to explore its unique dungeons and rarer resources that don't exist in base RLCraft terrain — losing that world to a bad update means losing exploration progress you can't regenerate the same way twice.
