Effects
- Spawns a crawling Leech familiar that follows Isaac. If an enemy comes near, the Leech will attack and chase it, doing 1.5 damage per tick or about 3.2 damage per second. If an enemy is killed by the Leech, Isaac will be healed by a Half Red Heart.
Synergies
- BFFS! - Leech grows bigger and does double damage. Still only heals for a Half Red Heart.
- E Coli - Enemies can be turned into poop at the cost of a Half Red Heart, then consumed by the leech to regain health. Utilization of temporary immunity when hit can allow multiple enemies to be turned into poop, resulting in a net gain of health.
- Flush! - The leech still can attack the enemies turned into poop and gain health.
- Gnawed Leaf - The player can stand still and allow the Leech to clear a room, granting simple clears and easy health.
