Kimetsu no Yaiba (Demon Slayer) Server Hosting

We recommend 5 GB. The pack only carries 46 mods, so memory goes mostly to loaded chunks and to the mobs and effects that combat produces. Groups that split up to hunt in different corners of the map load more chunks at once, so raise memory a step if your players rarely travel together.

Around six is the sweet spot on 5 GB. That is a full squad for joint hunts without the server juggling too many separate areas. Larger groups can play as well, but give the server more memory and pregenerate the world so newcomers exploring the edges do not cause lag spikes for everyone.

Make a backup in the panel, then pick the new build in the Modpacks tab. Read Kesselot's changelog before you switch, because Demon Slayer content that is removed or renamed between builds can leave gaps in your world. If your world holds a lot of progress, test the update on a copy first.

Yes. Put extra Forge 1.20.1 mods in the mods folder over SFTP or the file manager, and make the same change on every player's client, since Forge expects matching mod lists. Avoid deleting the mods that supply the Demon Slayer content itself, or their items and blocks will disappear from the world.

All the Mods 9 also runs on Forge 1.20.1, but it bundles hundreds of mods and centres on tech and magic progression. Kimetsu no Yaiba keeps to 46 mods and a single theme, so it needs far less memory, starts faster and suits groups who want an anime combat adventure instead of a long automation grind.

Yes. Every player needs the same build as the server, currently 2.1.3, installed through a launcher that handles Modrinth packs, such as the Modrinth App or Prism Launcher. A mismatched build usually fails at login with a mod list error, so update the server and every client at the same time.
