Dad's Ring is an unlockable passive item added in The Binding of Isaac: Afterbirth †.
- Creates a ring of light around Isaac that petrifies enemies on contact.
- Normal enemies stay permanently petrified as long as they are within the ring, whereas bosses get a standard petrification effect that stays even outside the ring but isn't permanent.
