About this Mod
A difficult mod that sets max health to 1 heart. Everything is much riskier, and any damage could be fatal... Good luck.
The name and concept of this mod is inspired by the Hollow Knight mod by a similar name
READ BEFORE USE
Version 1.20.1 is FORGE, and will be the only forge version, so don't bother asking for an update.
1.20.1 requires the mod to be CLIENT and SERVER, whereas all the other ones only need to be on the SERVER
Health can be configured, for those of you who find it too hard
Setting it to 0 or less will set it to 1
To change max health, execute one of the following commands:
Singleplayer, Cheats disabled:
/setmaxhpsingleplayer <value>
BE WARNED! In a LAN world, people without cheats will still be able to toggle this value.
Anywhere, Cheats enabled:
/setmaxhp <value>
A Fabric, Paper, Datapack, and Spigot version are planned to release, but for now don't exist
Other Site versions:
I would personally recommend Modrinth, as it is easier to use, but this mod is still available on Curseforge.
