Bloody Lust is an unlockable passive item.


  • Damage increases as Isaac receives damage. The damage increase stays for the whole floor, but resets upon entering a new floor.

    • Any damage taken past the sixth hit does not further increase damage.
  • Isaac becomes redder as his damage increases.
