Heartbond

Everyone who has this mod installed shares one life.

Take a hit and everyone takes it. Die and everyone dies. Eat a golden apple and everyone feels better.

For Minecraft 26.2 (Fabric).

Installing

1. Install Fabric Loader for Minecraft 26.2.
2. Put sharedhealth-1.0.0.jar and Fabric API in your mods folder:
   • Windows: %appdata%\.minecraft\mods
   • macOS: ~/Library/Application Support/minecraft/mods
   • Linux: ~/.minecraft/mods
3. Everyone who should share health needs both files. If you are playing on a server, the server needs them too.

That is the whole setup. There is nothing to configure, no command to run, and no invite to accept. The moment two people with the mod are on the same world, they are bound.

Players without the mod are not affected in any way. They can play on the same server normally.

What is shared

Damage

A wound one person takes is dealt to everyone else bound to them, for the same amount. It ignores armour, shields, resistance and invulnerability frames, so the echo hits for exactly what the original hit was worth. Your netherite does not protect you from your friend's mistakes.

Health

Everyone in the bond sits at the same health, always, pulled down to whoever is lowest. This works in your favour too: healing lifts everyone. One person eating a golden apple or standing in a regeneration beacon heals the whole group.

Death

When one person dies, everyone else follows one second later. You get a warning on your action bar and a heartbeat in your ears first, so you know why it is coming.

A totem of undying still saves you from this. Keep one on you.

Attunement, the reason to stay bound

Being bound is not pure downside. Every extra member of the bond gives everyone +1 heart of maximum health, up to +10 hearts.

A large bond is far tankier than a lone player. It is also one bad decision away from a full wipe.

The Heartbond bar

A red bar sits at the top of the screen showing the shared life remaining and how many people are bound. It turns purple below 25 percent, which is your cue to stop what you are doing.

The bar only appears when at least two people are bound.

Leaving and rejoining

/heartbond leave steps you out of the bond. /heartbond join steps you back in.

Leaving is remembered. If you log out while unbound you stay unbound when you come back, so a relog will not quietly drag you back in.

Server operators can turn leaving off entirely with the allowLeaving setting, and can pull people in or out themselves with /heartbond bind and /heartbond release.

Damage modes

Server operators can change how damage spreads with /heartbond mode <mode>.

mirror is the default. Everyone takes the full amount. One person's mistake is everyone's.

split divides the hit evenly across the bond and refunds the victim their share. With five people bound, a 20 damage anvil becomes 4 damage each. This turns the bond into armour and makes a big group genuinely hard to kill.

pool turns off mirroring entirely. Health is still shared and healing still spreads, but hits are not echoed. The quiet option.

Commands

Settings

A file appears at config/sharedhealth.json the first time you run the mod. Edit it and run /heartbond reload to apply changes without restarting.

The ones worth knowing about:

Things worth knowing

• Creative and spectator players are left out by default, so an admin flying around will not drag the group down.
• A totem of undying beats the death cascade. If one person dies and you are holding a totem, you survive and the others do not.
• Falling, drowning, lava, starvation and poison all spread. Anything that damages one of you damages all of you.
• Regeneration is shared but slow. The whole group heals at the rate of one player, because everyone is held at the lowest health. Food and potions are much faster.
• allowLeaving: false plus shareDeath: true is the hardcore setup. Nobody can opt out and one death ends the run for everyone.
