Description

  • [Friendly] Clearing a room has a 25% chance to spawn a friendly Bony

Effects

  • After clearing a room, adds a chance to spawn a friendly Bony / Black Bony.

Synergies

  • Mom's Box / Golden Trinket: Increases the chance to spawn bonies.

Interactions

  • Ace Cards: Friendly monsters are still affected by Ace Cards.
  • Blood Puppy: Either version of Blood Puppy will target friendly enemies and can drag them along with it when it charges them. Blood Puppy cannot damage friendly enemies; however, friendly enemies can damage Blood Puppy despite not targeting it.
  • Broken Modem: Broken Modem also affects friendly enemies and projectiles created by them.
