FWG's backup server for BlooCraft, on the newer Dungeons and Dragons pack for 1.21.1: 282 mods of Create airships and cannons, Iron's Spells and Ars Nouveau magic, Origins classes, Ice and Fire dragons, and Cataclysm bosses.
Install Prism Launcher (free) and sign in with your Microsoft account.
Download the FWG instance below. In Prism, choose Add Instance → Import and select the zip.
Launch it. The first start downloads the whole pack (about 1 GB). 5 mods (CBC Aeronautics Missiles, More Propulsion, Better Villages, Hackers 'n Slashers, and Library Ferret) can only be downloaded from CurseForge: a window gives you the links. Save each file to the folder it shows, then continue. You only do this once.
That's it. Every launch checks for pack updates and installs them automatically.
This version does not update automatically. The pack isn't on CurseForge yet, so the CurseForge app can't update it for you. When the pack updates, download the new zip here and import it again. The Prism instance above updates itself on every launch.
Download the zip below. Don't unzip it.
In the CurseForge app: Minecraft → Create Custom Profile → Import, then pick the zip.
Launch the new profile. The first start downloads every mod, so give it a few minutes.
