Crystalized Hearts

Crystalized Hearts introduces a new regenerative resource system to your world, blending atmosphere, exploration, and progression into a simple but rewarding gameplay loop. Scattered between Y-levels -24 to 56, these mysterious crystals offer powerful survival benefits to players who discover and cultivate them.

World Generation: Crystal Heart Blocks
Bright pink Crystal Heart Blocks naturally spawn underground in small clusters of 1 to 3.
They are completely indestructible and unmovable by pistons, acting as permanent anchors for Heart Crystal growth.

Crystal Heart Blocks function as block entities, allowing them to properly track and manage crystal growth stages.
They random tick naturally

On each random tick, if the block above is air, it will generate a new Heart Crystal one block above it.

The Heart Crystal that it generates can be destroyed by a piston, allowing automated farms, if set up correctly

Heart Crystal Growth System
Heart Crystals develop through 10 distinct stages and are registered under the mod’s dedicated heart crystal stage block tag

Every 5 seconds, a Heart Crystal advances to the next stage.

Shard Progression System
Heart Crystals reward players throughout their entire growth cycle:

Stages 1–4 drop 1 Heart Crystal Shard Small
Stage 5 drops 2 Heart Crystal Shards Small
Stage 6 drops 3 Heart Crystal Shards Small
Stage 7 drops 1 Heart Crystal Shard
Stage 8 drops 2 Heart Crystal Shards
Stage 9 drops 3 Heart Crystal Shards

This is so that if the player mistakenly destroys the crystal before maturity, they don't get nothing.

Crafting & Refinement
Heart Crystal Shard Small can be crafted into Heart Crystal Shards.
Heart Crystal Shards can be crafted into a full Heart Crystal.

This allows players to get something from their mistakes; moreover, doing this—constantly destroying the crystals before maturity—is less effective, enhancing this gameplay-loop.

Fully Mature Heart Crystal
At Stage 10, the crystal becomes fully mature and harvestable.

Breaking a fully grown Heart Crystal with a wooden pickaxe or better yields:

2 experience points
1 Heart Crystal item

Heart Crystal Item Effects
Consuming a Heart Crystal grants powerful defensive buffs:

Regeneration II for 15 seconds
Absorption III for 60 seconds

These effects make Heart Crystals an excellent emergency resource, exploration tool, or late-game combat advantage.

Crystalized Hearts rewards patience, planning, and progression — turning underground exploration into a renewable survival advantage.
