"Consume thy enemy!"


  • After firing tears for 2.5 seconds, releasing the fire button unleashes a black ring around Isaac that expands and contracts, dealing damage at a rapid rate to all enemies touching it.
    • The charge is completed when a red upside-down cross appears on Isaac's forehead.
    • With charge bars enabled, there is also an indicator that displays the charge.
    • The black ring deals damage equal to Isaac's current damage per tick, and ticks a total of 30 times.
      • Black Hearts will drop as soon as the enemy is killed. (In other words, the heart will drop at the beginning of the death animation rather than at the end of the death animation.)
