lostheart

Lostheart makes death matter by removing heart containers on each death. Players slowly regain lost hearts over time, but if all hearts are gone, they enter spectator mode until some hearts return.

About this Mod

Lostheart - Minecraft Fabric Mod (1.21.X)

Lostheart is a Fabric mod for Minecraft 1.21.X that adds a challenging health system mechanic:

Every time a player dies, they permanently lose a configurable number of heart containers.
Lost heart containers regenerate gradually after spending configurable time online.
When a player runs out of heart containers, they are placed in Spectator mode until they regain at least one heart container (optional).
All key settings like heart loss amount, regeneration time, and spectator return can be customized via an external config file.

This mod adds strategic survival depth and makes deaths more impactful, encouraging careful play and persistence!

settings can be found at "YourServerFolder"\config\lostheart.properties

base setting: allowRetrunFromSpectator=true, heart ContainerLostPerDeath=1, heartRegenTimeSeconds=3600(1h)
