One Life
by teboplays
One Life turns the death of a character into a permanent end for that run, moving the player into spectator mode instead of a respawn.
What it does
When a player dies in One Life, the game switches them to spectator mode, which works like hardcore mode but does not lock the world behind a separate hard mod. The mod is for NeoForge only, with a single build, 1.0.0, for 1.21.8, and it is client and server, so both the server and every player need it. The license is All rights reserved, so the code is not open source.
Key features
Spectator after death
A death sends the player into spectator mode, so the run ends there while the world remains open to watch.
Hardcore-style rules
The one-life rule follows the same idea as hardcore mode, without requiring a locked hard mod to enforce it.
Difficulty as a life rule
Difficulty settings can be combined with the one-life rule, from the gentlest setting to the harshest.

What the author says
This mod makes it so if you die ingame, you go into spectator mode, like hardcore mode, but without the locked hard mod difficulty, meaning for example, you could have one life (just like hardcore mode) but with easy mode.
