  • Binge Eater Binge Eater: All shops become free stat-ups if the food item is chosen.
  • Restock Restock: The price never increases, staying at one red heart container/three soul hearts for each item, and one full heart of damage for pickups.
  • Maggy's Bow Maggy's Bow: Buying a Red Heart will out-heal the damage taken from the spikes if Isaac can survive it.
  • The Wafer The Wafer / Cancer Cancer / Percs!: The spikes only deal half a heart damage, allowing Isaac to gain health from buying hearts.

  • Keeper's Sack Keeper's Sack: Because shop items no longer cost coins, stat bonuses are no longer gained from buying shop items, but they are gained from Devil Deals.
