How to Mine and Use Heart Crystals to Raise Your Max Health

Finding the Ore

Heart Crystal Ore and Deepslate Heart Crystal Ore are your source of permanent max-health increases. Mine either block and it drops Heart Crystal Shard. Deepslate variants appear at lower depths, so bring a pickaxe that can handle deepslate and light your tunnels well.

Turning Shards into Hearts

Collect Heart Crystal Shard drops from the ore. Use the crafting recipes available to you to combine shards upward into a Heart Crystal. Once you hold a Heart Crystal, use it to add to your maximum health. Each Heart Crystal you consume permanently raises your health ceiling, so this is the core progression loop: mine ore, gather shards, craft a Heart Crystal, use it, repeat.

Bandages and Medkits

Bandages and Medkit are your healing consumables while you work toward more hearts. Keep Bandages on hand for topping up between fights, and save Medkit for when you have taken serious damage. Heart Dust is another material tied to this progression chain, so do not discard it when it appears from your processing steps.

Practical Order

1. Mine Heart Crystal Ore or Deepslate Heart Crystal Ore.

2. Bank every Heart Crystal Shard.

3. Craft shards into a Heart Crystal.

4. Use the Heart Crystal to raise max health.

5. Carry Bandages for routine healing and a Medkit for emergencies.

Repeat until your health bar is as large as you want it. Deeper mining gives you access to the deepslate ore, which keeps the loop going once surface ore runs dry.
