Heart Crystals
Heart Crystals adds rare heart-shaped crystals that generate underground, and each one used permanently raises the player's maximum health by one heart.
What it does
Crystals are found in caverns and chasms during exploration. Using a crystal grants one extra heart for good, so a player's maximum grows over time, starting from five hearts in a new world and rising to a limit of twenty. Both the starting value and the maximum can be set in the config file, which lets a server owner tune how quickly health grows.
Crystal shards and the crystals themselves feed a set of crafted items. Heart Lanterns, Cupid's Arrows and potions for regeneration are made from them, and the Heart Lantern has an alternate recipe that uses living flesh in place of silver ingots. Potions draw on trim material as an ingredient. The mod is a Forge and NeoForge build that requires Blueprint, and it runs on client and server, so the server and every player need it.
