About this Mod
❤️ Heart Harvest
Kill mobs. Grow stronger. Never stop.
Heart Harvest rewards you with permanent max hearts for every mob you slay. The harder the fight, the greater the reward. Grind your way to an enormous health bar — or lose it all on death if you dare.
💀 How It Works
Every kill earns you permanent max hearts based on how dangerous the mob is. Hearts persist through sessions and server restarts automatically — no commands needed.
| Tier | Hearts Gained | Mobs |
|---|---|---|
| 👑 Boss | +10 ❤️ | Wither, Ender Dragon, Warden |
| 💀 Hard | +3 ❤️ | Blaze, Ghast, Elder Guardian, Shulker, Breeze, Wither Skeleton, Guardian, Piglin Brute |
| ⚔️ Medium | +2 ❤️ | Zombie, Skeleton, Creeper, Enderman, Witch, Pillager, Ravager, Evoker, and more |
| 🕷️ Weak | +1 ❤️ | Silverfish, Endermite, Slime, Cave Spider |
| 🐄 Passive | +½ ❤️ | All passive mobs |
