Inspired by the lack of a mod on Forge similar to this: https://www.curseforge.com/minecraft/mc-mods/sharedhealth
Server-side Shared Health and Hunger links all players together by forcing everyone to use the same health and hunger values. If one player takes damage, everyone’s health drops. If someone eats or loses hunger, the shared hunger pool changes for everyone as well.
Intended for Hardcore ONLY (respawn edge-cases are NOT handled).
