Leeching Crystal is achievement-related item in Megabonk. You will get it only when you meet a specific requirement.. Leeching Crystal is a high-impact survivability modifier: it massively increases your health pool while throttling your passive regeneration. If you're browsing the full item database, think of it as a "big tank, low idle healing" switch. Stacks: multiple copies further reduce regen; over-stacking can nullify sustain—pair with lifesteal or burst healing.

Titel says it all, i try to get all Achievmetns and "Kevin" says: "Obtain 3 leeching crystals in a run." but i never found or saw even one.
