How to Host an All the Magic Spellbound Server

Start your server plan at 6 GB RAM minimum. That's the recommended floor for All the Magic Spellbound itself — Thaumcraft, Blood Magic, Botania, Ars Nouveau, and Astral Sorcery all run their own tick-heavy systems at once, and undersizing the heap here shows up as garbage-collection stutter during ritual and aspect calculations rather than a clean crash.

Import the modpack through a proper modpack installer rather than guessing from a client export. All the Magic Spellbound ships as a curated Forge 1.16.5 pack with a quest guide wiring all five magic mods together — hand-copying a client's mods folder is the easiest way to end up with mismatched versions or missing server-side dependencies.

Watch the console through first boot and don't touch anything until it says done. On a magic-only pack like this, most startup errors come from Thaumcraft or Astral Sorcery world-gen hooks failing to register — if the log stalls or throws repeated errors instead of reaching the final "Done" line, stop and fix it before anyone joins.

Only invite players after you've confirmed one full clean startup. Spawning players into a half-initialized world is how you get corrupted Blood Magic altars or broken Astral Sorcery constellation data that's a pain to repair after the fact.

Take a backup before importing a world, updating the Forge loader, or changing any mod config. Progress in this pack is almost entirely tied to Thaumcraft research, Blood Magic rituals, and Astral Sorcery constellation unlocks — all of it keyed to world save data that a bad update or a careless config edit can wipe in seconds.
