How to Host a Hexxit Updated Server (Forge 1.16.5 Setup Guide)
Hexxit Updated is a community revival of the original Hexxit adventure pack, rebuilt on Forge 1.16.5 with the same spirit: dungeons everywhere, treasure hunting, and raw exploration-focused combat. It's not the same pack as Hexxit Revived, a separate faithful port running on Forge 1.20.1, and it skips DawnCraft's Souls-like combat system entirely in favor of classic dungeon-crawling. Here's how to get it running cleanly before you invite anyone in.
Start with 6GB of RAM — that's Hexxit Updated's own recommended floor for Forge 1.16.5, enough to cover the modpack's dungeon structure generation and loot tables without the server choking the moment someone opens a vault.
Import the modpack through a clean CurseForge/Modrinth pull instead of zipping up a client install and guessing at the server-side mod list — this keeps the Forge loader version and the 1.16.5 base locked to exactly what Hexxit Updated ships.
Watch the console through the first full boot: Hexxit Updated leans on custom dungeon and treasure-generation mods, so you want to see world setup finish and the server reach "Done" with no mod-loading errors before you trust it.
Don't invite your group until that first boot has completed cleanly — a crash mid-world-gen on a dungeon-heavy pack like this can leave structures half-generated, which is far worse to fix once players have already started looting them.
Take a backup before any world import, loader update, or config change — on a modpack built around dungeon loot and treasure hunting, a bad update that corrupts the world means losing hours of exploration progress, not just blocks.
Use a cleaner Hexxit Updated path
CoalHost is built around modpack hosting, which makes Hexxit Updated much less annoying to launch correctly.
