Firmcore

by Tobindog100

Firmcore is a NeoForge adventure mod that sits between the softcore and hardcore death rules, costing hearts on each death.

NeoForgeClient and serverAll rights reserved26.1 – 26.1.2

What it does

Each death removes hearts, and the number lost depends on the chosen difficulty. A player who runs out of hearts is switched to spectator mode, and the world is expected to be deleted. The mod aims at players who find KeepInventory too forgiving and full hardcore too strict. It is recommended alongside KeepInventory, which is required, and it runs on client and server so both sides need it. Only NeoForge files are published, for 26.1 – 26.1.2, under All rights reserved, and the code is not open source.

Key features

  1. Heart loss on death

    Every death costs hearts, with the amount tied to the difficulty setting.

  2. Spectator mode at zero hearts

    A player who loses all hearts is moved to spectator mode, and the world is expected to be deleted.

  3. Middle ground between rules

    The mod offers a point between keeping inventory on death and strict hardcore play.
