Get through both floors of Corpse and you'll find Mother waiting for you. Go through that door, defeat the upgraded Mom's Heart, then jump through the trapdoor into Corpse. Defeat her, then use your specially crafted knife to open the flesh door that appears afterwards (this will destroy the knife). Mausoleum is difficult and you'll have to make it to the second floor, where a more powerful version of Mom awaits you.
BINDING OF ISAAC REBIRTH LOST FULL
You'll have to poke yourself with it twice, inflicting two full hearts of damage (the Lost can do this for free), to open it and enter Mausoleum, another new environment. After defeating the floor boss here in the Mines, you'll see a new door with a sharp thingy sticking out of it. Great job so far! We're still not done though. If you can fly, either with Azazel or the Lost, this will be much easier (I forgot to mention you will lose all your items when you ride the minecart, so if you have flight from an item, you lose it temporarily during the Mother's Shadow portion).

You'll have to use bomb grimaces and quick reflexes to get out of here. Every few seconds she will charge you, this is easily dodged but the path will get in your way. She is invincible so don't try to hurt her, just run. She will chase you all the way back to the minecart room. Mother's Shadow will appear, she's a pain in the ass. At the end, grab the second piece of the knife.

Go all the way through these empty rooms, taking note of the path as you go. Once you have pushed all 3, hop in the minecart and it will take you north to a secret area. They will be in 3 different rooms (one of them is the minecart room). On the second floor of the mines, you need to look for 3 yellow buttons on the ground. Grab the knife piece in the treasure room and then return through the mirror.Īfter you defeat the boss on this floor, you'll need 2 bombs to open the door to the Mines. In the mirror world you need to get to the treasure room, be careful on the way because some rooms might have repopulated with enemies. Once you have found all 3, touch the white fireplace to turn into the Lost. On the second floor of Downpour, you'll need to find 3 rooms: one with a white fireplace, one with a mirror on the wall, and the treasure room. The blue door leads to a new environment, Downpour. On the first or second floor, save a key to open the blue door after defeating the floor boss. It will take some planning right from the beginning of your run. Which is earned for defeating Hush 3 times, which unlocks Downpour.ĭefeating Mother is difficult, but getting to her is also a process.
