Leeches

Leeches is a damage-over-time debuff that drains HP from the afflicted unit and transfers it to the source that applied the effect. Unlike standard DoTs like Burn or Bleed, Leeches provides healing to the enemy, making it doubly dangerous: your cat loses HP while the enemy recovers.

Leeches is particularly frustrating against tanky enemies that already have high HP, as the healing they receive from Leeches can offset your team's damage output. Cleansing Leeches quickly is important not just to save your cat's HP but to deny the enemy its healing source. Leeches is applied by parasitic and blood-themed enemies and some dark-element abilities.
