Mom's Heart is the final Boss of The Womb 2. In the beginning of the battle, it is always accompanied by two Eyes.

After Mom's Heart has been defeated nine times, it is replaced with It Lives!.

Behavior

Mom's heart spawns two to four Monsters and then disappears. After killing those monsters, the heart will reappear in the middle of the room for 3–4 seconds, spawn more monsters, then disappear again. If you manage to kill the monsters within two seconds from their spawning (before the Heart disappears), Mom's Heart will stay on screen and spawn a next pack.

Eternal Mom's Heart has a similar set of behaviors, chasing the player around the room and spawning two to four Eternal Monsters. It attacks frequently during the battle, spawning blood bombs and making red Creep. Unlike the normal variant, Eternal Mom's Heart stays on screen at all times. If you manage to kill all the monsters in the room, the next pack of monsters will be spawned instantly. When Mom's Heart is on low health, it will spawn blood bombs at a faster pace.

Strategy

Provided you have bombs, placing a bomb just as the heart is about to drop into vision will not only damage the heart, but may also destroy any monsters the heart spawns; this can afford you essentially double the attack time against the heart.

When Mom's Heart drops down to 33% health, it will stop hiding but continuously spawn monsters and start firing blood bombs similar to IPECAC shots. The explosions leave a large puddle of red Creep that damages Isaac on contact. The monsters it spawns in this phase are usually weaker, consisting largely of various small flies.

If you are lucky enough to make it to Mom's Heart with technology, stand on the same horizontal line as it on either side and just hold down the attack button. If you've positioned yourself right, everything it spawns will be in the same line as your fire, effectively killing it and damaging the heart without any movement.

Alternatively, using The Bible will act as an instant kill, similar to using it on Mom.

Champion Variants

Eternal

Mom's Heart is much more difficult to defeat when it is Eternal, but it stays on the screen at all times. Moving around the creep is difficult and you'll likely suffer a few points of damage, but it's not impossible to manage. More troubling is the constant spawning of Eternal creatures-- if you haven't met enough of them because you rushed the Womb, you might have difficulty handling their unique attack patterns. Check their individual pages to learn the strategies for dealing with them, and treat them as if you were fighting them in a Vomit Grimace room.

Trivia

  • The music of the fight has faint sounds of heartbeats.
  • If you listen closely, you can hear Isaac's mom groaning in the background. This is the same for It Lives.

Bugs

  • When defeating Mom's Heart using the Bible, the health bar will not disappear, but the game will go on with the ending as usual and the chest will appear (seems to have only appeared since The Wrath of the Lamb was released)
  • If you are in the Womb XL or Utero XL, then the boss right before Mom's Heart/It Lives! will also play the heart's music, and Mom's Heart/It Lives! will still play its own music. This also occurs with Mom in The Depths XL and Necropolis XL.
  • If Mom's Heart or It Lives is taking multiple hits of damage right before it starts firing bombs, many occurrences of it saying "Isaac!" happen. An example of this is when Technology 2 is being used.
  • If you kill yourself after defeating Mom's heart, but have a respawn item (1up, Ankh, Guppy), when you return to the room, mom's heart will have returned, but the chest is still there. You must wait for the heart to rise back up before running into the chest. The game goes on normally after opening it.
  • If Mom's Heart or It Lives is damaged enough to start firing bombs before it comes down from the roof (via The Candle), it will stay on the roof and its shadow will remain, but bombs will still be fired from the center of the room.
  • If Mom's Heart is dropped below 33% while it is raised (i.e., poison, Blue Candle bug, etc.), but there are still spawned monsters in the room, Mom's Heart will begin to fire bombs, but will not drop from the ceiling until the spawned monsters are killed.
