Effects[edit | edit source]
- Grants a chance to fire poison tears, dealing damage over time when inflicted.
- Inflicts poison on enemies who make contact with the character.
- Enemies who are killed after they have been inflicted with this type of poison have a 20% chance to drop Black Hearts.
Notes[edit | edit source]
- The contact and poison effects of this item are identical to The Virus, but does not include a Speed down.
- This item and The Virus are the two only poison sources to have a chance to drop black hearts.
- Enemies and bosses with multiple segments, such as Chub and Larry Jr., have a chance to drop multiple Black Hearts.
- The enemy does not need to be killed by the poison or still be poisoned when killed for the Black Hearts to drop.
- Although Stonies and Shopkeepers can't be visibly poisoned, they still can drop Black Hearts if destroyed after being touched.
Interactions[edit | edit source]
- Tech X: The laser will poison enemies but never generates black hearts.
- Technology: The laser will poison enemies but never generates black hearts.
- Technology 2: The laser will poison enemies but never generates black hearts.
Synergies[edit | edit source]
- Athame: The black ring created by the Athame applies the poison from Serpent's Kiss. This means enemies killed will have a higher chance to drop black hearts.
- Invulnerability: Contact while invincible poisons enemies.
- Euthanasia/ Little Horn: Allows harvesting endless black hearts from Stone Grimaces as they can be (invisibly) poisoned by touching them, then destroyed with Euthanasia/Little Horn and made to respawn by leaving the room.
- Scorpio: Grants the character a 100% chance of firing poison tears.
- Second Hand: Extends the duration that enemies stay poisoned, dealing more damage over time.
- Soy Milk: The low damage and high fire rate increases the chance of enemies and bosses being poisoned.
- The Common Cold: Adds to the chance of firing poison tears, based on the character's Luck stat.
