If you want to boost your health in Megabonk, the Leeching Crystal is the best item to grab. It increases your max HP by 50%, giving you a much bigger health pool, but lowers your health regeneration rate by half. You can also unlock the Kevin achievement by collecting 3 Leeching Crystals in a single run. I’ve got you covered with this guide.
How to Get the Leeching Crystal in Megabonk
To unlock the Leeching Crystal in Megabonk, you need to upgrade the Regen Tome to level 8 in a single run. Reaching this level unlocks the Leeching Crystal and adds it to your item pool.
After you unlock the Leeching Crystal, it shows up as a blue-tier item during your runs. To increase your chances of finding it, use the item toggler to disable other blue items you don’t need. And play on Tier 3 maps since more items appear there.
Leeching Crystal Effects
- +50% max HP
- -50% natural health regeneration
The Leeching Crystal increases your max HP by 50%, giving you a bigger health pool to take more damage. At the same time, it cuts your natural health regeneration by half.
How to Use the Leeching Crystal in Megabonk

The best way to use the Leeching Crystal is to combine it with items or skills that heal you in other ways. Lifesteal items like Demonic Blade or Chonkplate are great choices because they heal you whenever you hit enemies.
This item fits perfectly with tank builds that focus on stacking max HP and armor, since healing speed matters less in those setups. Just be careful not to pick up multiple Leeching Crystals in a single run—it greatly slows down your health regeneration and makes healing much tougher.
That’s all you need to know to unlock the Leeching Crystal in Megabonk and how to use it effectively.
