Leeches

Leeches is a debuff that drains 1 health per stack from the afflicted unit at the end of the applier's turn, transferring that health to the applier. This creates a sustained health drain that simultaneously damages the target and heals the source, making it a powerful sustain tool for the enemy that applied it. Leeches is persistent and does not decay on its own.

The health drain triggers on the applier's turn end, not the afflicted unit's turn. This means killing the applier stops the drain entirely, as the trigger condition no longer occurs. Multiple stacks of Leeches drain more health per trigger, potentially dealing significant damage over time while providing substantial healing to the source. The drain affects health directly, bypassing Shield.

When your cats have Leeches applied, prioritizing the source enemy is the most effective counter, as killing it removes both the health drain and the enemy's healing. Mana Leeches is a similar variant that drains mana instead of health. Both variants target different resources but share the mechanic of applier-turn-end draining with a direct transfer to the source.
