What it does

Players use the mod to build their own Modded UHC games. A book inside the mod lets the player change the settings of a run, and the author notes a setting that is still missing and will be added later. Client and server both need the mod, which is published for 1.12.2 and 1.21.1, with the latest NeoForge build an alpha for 1.21.1.

Key features

  1. UHC settings book

    A book in the mod opens a screen where the player changes the rules of an Ultra Hard Core game.

  2. Modded UHC support

    The mod helps create Modded UHC games, combining the hardcore rules with other installed mods.

  3. Inspired by UHC Blox

    The book follows the layout of the UHC Blox book, which the author took as the model for this mod.

Questions

Does Ultra Hard Coremod need to be on the server?

Yes. A server running it needs every connecting player to have it too.

What the author says

(No, this mod is not a coremod. That's the joke) A mod that allows people to create Modded UHC's.
