A Heart of Crystal

A mod that adds a rare ore that lets you increase your maximum health and causes you to lose a heart upon death, making your hearts a precious resource.

New items:

• Heart Shard
• Heart Crystal

Hold right-click for 2 seconds to consume and gain one heart (Also doubles as a musical instrument).

• Heart Crystal Upgrade (Unobtainable in Survival as of v1.1.0)

Used to create the Heart Crystal Chestplate in a Smithing Table

New Equipment:

• Heart Crystal Chestplate (Unobtainable in Survival as of v1.1.0)

Grants varying levels of Regeneration while equipped, based on how much health you have.

11+ hearts: Regeneration II

6-10 hearts: Regeneration I

5- hearts: None

New blocks:

• Heart Crystal Ore & Deepslate Heart Crystal Ore

Generate similarly to Ancient Debris in the overworld from Y: 16 to Y: -64.

• Heart Crystal Block

New gamerules:

• Lose heart upon death

If the gamerule “heartLossUponDeath” (“Lose heart upon death”) is enabled, upon dying, you will lose one heart of max health (With a minimum of 3 hearts). This can be toggled on/off, but is turned off by default as of v1.1.0.

• Number of hearts to start with

You can set the number of hearts you start the game with with the gamerule “startingHearts” (“Number of hearts to start with”). By default, this is the vanilla 10 hearts. This can’t be set below 3 or above 10.

I wanted to do my own take on this kind of mod, since I like the idea of it being an ore and I think the Heart Crystal concept could work well with the idea of max health loss (I know that part isn’t for everyone though, hence it being opt-in via the “heartLossUponDeath” gamerule) and the idea of starting a world with fewer hearts. If you choose to use this mod, I hope you enjoy it! And feel free to use this mod in modpacks if you want, I’m sure it’d work well with other mods. 🙂

(NOTE: I have yet to test this in a multiplayer environment, so there may or may not be bugs related to that. If there are, please let me know)

(NOTE 2: I removed the Heart Crystal Chestplate as it honestly felt like bloat to me, but I may or may not add it back in the future. Not sure tbh. I kept the item itself in the game because I didn’t feel right removing it outright (Especially cause some people may have already obtained it and I don’t wanna rip it away from them if/when they update), but it is no longer obtainable in Survival, only via the “/give” command)
