What it does

Heart Crystal Ore generates in the deepslate layer below Y 16 and can be mined for Heart Shards and Heart Crystals, which are used to raise a player's maximum health. A held Heart Crystal is consumed over two seconds of right-click to add one heart, and the Heart Crystal Upgrade and Heart Crystal Chestplate are crafted at a Smithing Table. The chestplate grants regeneration whose level depends on how much health the wearer has.

Two gamerules control the health rules of a world. heartLossUponDeath, which is off by default, makes a player lose one heart on death, which makes hearts a scarce resource. startingHearts sets how many hearts a new player starts with, between 3 and 10, with vanilla at 10. The mod supports client and server, so the server and every player need it, and it is released under All rights reserved, so it is not open source. Files exist for Forge and NeoForge across 1.20.1, 1.21.1 and 1.21.4.
