|-|Mom's Heart=
*Phase 1: At the beginning, Mom's Heart summons two Eyes, then retreats upwards into the ceiling. Then, it will summon two more Eyes while shooting four diagonal streams of blood projectiles in a spread that slowly rotates clockwise, then alternate between these two attacks:
**Lower itself and perform one of these bullet patterns:
***10 projectiles in all directions that expand outwards either continuously or in a pulsating manner.
***2 streams of projectiles that spiral outwards.
***2 rings of ten projectiles that pulsate outwards at different intervals.
***8 slightly curved lines of projectiles that rotate and expand outwards slowly.
**Retreat into the ceiling while firing the four streams of bullets again, and summon two waves of kind of enemy between two Flesh Mobile Hosts, three Globins or two Eyes.
*Phase 2: The Heart begins to beat and attack faster.
**Its projectile patterns now include:
***A single line of projectiles that follows Isaac.
***5 lines of projectiles that mimic Isaac's movements (these lines have no space between projectiles).
***3 pulsating curved lines of projectiles that rotate and expand outwards. This pattern can occasionally change direction of rotation.
**Its spawned monsters are now two pairs of three Lumps, two Swingers or of three Globins.
*Phase 3: The Heart no longer ever retreats and attacks even faster.
**Its projectile patterns are now:
***4 curved lines of projectiles that continuously rotate and expand outwards.
***2 streams of projectiles that spiral outwards.
***8 slightly curved lines of projectiles that rotate and expand outwards slowly.
**Its summoned enemies are now two waves of four Walking Boils, four Tumors or four Hearts
*Phase 4: The Heart now beats many times per second, and is near death.
**The Heart stops firing and shoots four Brimstone blood beams in the four cardinal directions and rotate them across the floor.
**Upon defeat, Mom's Heart fires out a ring of 14 projectiles.

|-|Mom's Heart (Mausoleum)=
*Phase 1: Mom's Heart once again summons two Eyes at the beginning, then retreats upwards into the ceiling, shooting four diagonal streams of blood projectiles in a spread that slowly rotates clockwise. Then, it descends, and will not retreat upwards anymore, executing these attack patterns in random order.
**2 rings of 8 projectiles at different intervals that expand outwards overlapping on each other either continuously or in a pulsating manner.
**2 streams of projectiles that spiral outwards and gradually increase in density.
**2 rings of 8 projectiles each ring expanding and alternating between rotating clockwise and counter-clockwise.
*Phase 2:
** 5 lines of projectiles that rotate and pulsate outwards.
** A combined ring of 2 rings of 8 projectiles that rotate in opposite directions while expanding.
** 16 wavy streams of projectiles that intertwine and create gaps.
** 16 streams of projectiles that curve back towards Mom's Heart and intertwine to create gaps.
** 5 waving lines of projectiles that rotate and expand outwards.
*Phase 3:
** 6 curved lines of projectiles that rotate in opposite directions while expanding- 3 clockwise, 3 counter-clockwise.
** A ring of 12 projectiles that expands outwards, along with 2 rings of 4 projectiles that expand outwards and rotate in opposite directions at a higher speed.
** 2 streams of projectiles that spiral outwards and gradually increase in density.
** 2 rings of 8 projectiles, each ring expanding and alternating between rotating clockwise and counter-clockwise.
*Phase 4:
**Mom's Heart stops its previous projectile attacks and fires 2 Brimstone beams in opposite directions that slowly rotate either clockwise or counter-clockwise, as well as two continuous streams of projectiles, one that follows the enemy's movements and the other mirroring the first.
**Upon defeat, Mom's Heart fires out a ring of 14 projectiles and causes the environment to become slightly darker.
