What Doomsday is
Doomsday is a free Fabric mod that focuses hard on one niche: crystal PvP. It doesn't try to be a kitchen-sink client — the module list is tight and the code is tuned for tick-perfect end-crystal placement.
Doomsday modules
Crystal PvP: AutoCrystal, AutoTotem, Surround, Burrow, HoleFill.
Combat: Killaura, Reach, Velocity.
Movement: Sprint, NoSlow.
World: Scaffold, NoFall.
Render: ESP, HoleESP, Nametags.
Doomsday vs 4E vs Meteor for crystal PvP
4E is paid and slightly tighter. Meteor is free but broader (its AutoCrystal is fine but not specialised). Doomsday sits between them — free like Meteor, focused like 4E. For crystal-only players on a budget, Doomsday is the pick.
Installing Doomsday
Install Fabric Loader for your Minecraft version, download Doomsday's .jar, drop it in .minecraft/mods, launch the Fabric profile. Right-Shift opens the ClickGUI.
Where to use Doomsday
Practice servers with crystal-PvP arenas, small SMPs, offline testing. It's not built for Hypixel or Vulcan-tier anti-cheats.
