Rock Bottom Beat Boss Rush as Jacob & Esau.

Rock Bottom is a passive item.


  • Prevents stats from being lowered the rest of the run.
    • Damage multipliers can still be reduced by picking up items such as Soy Milk: Your current damage will not change but further damage-up will be lowered.


  • Experimental Treatment can still lower your stats.
  • This item can show up when tinted rocks are destroyed.
  • Soy Milk will not lower damage with Rock Bottom, however, Isaac's tears will still be very small.
