How to unlock the Judas achievement in The Binding of Isaac: Rebirth - Definitive Guide
In order to unlock Satan you have to defeat the depths at least once.
Sheol only has a chance of spawning whenever you defeat Moms Heart. However, after you defeat "It Lives" Sheol has a 100% chance to spawn.
The Satan Fight has 3 phases to it.
1. - First the boss "The Fallen" will spawn in along with 2 Kamikaze leeches. After "The Fallen" is defeated then Satan will spawn in phase 2
2. - Satan will have 4 set patterns that you will have to get used to in order to defeat him. 1.) Projectictiles that move to the left and right of the room. 2.) brimstone laser down the middle. 3.) Homing Brimstones from his hands. 4.) Scattering shots simular to Gurdy's attack from his mouth directed at isaac.
3. - Satan will begin to stomp around similar to Mom's Foot, but much quicker. The second foot will come soon after the first one. 2 Kamikaze leeches will spawn as well and will continuously spawn another after one of the leeches is defeated.
After this phase is defeated you will have defeated Satan and unlock Judas
Placing a bomb right before the fallen spawn will take down half their health and also the leeches.
In phase 2, I found that standing on the left/right side of the room and avoiding the tears while shooting satan to work.
Phase 3 is pretty easy but the leeches can make it tricky. Try to circle the room while avoiding mainly the leeches. Never backtrack as you'll get stomped on.
He has three forms: the first two are fairly simple, just keep moving and dodging his projectiles, and finally he'll turn similar to Mom and stomp down with two black, goat legs. You've got to be quick to avoid them - (I also believe that each stomp does two hearts worth of damage).
The Necronomicon (or the effect from Dry Baby) doesn't seem to work on him either.
Also, do not use the Bible on Satan or you will die!

In order to defeat Satan you must go to Sheol after defeating Mom's heart (take the trap door). Sheol only has a chance of spawning whenever you defeat Mom's Heart. However, after you defeat "It Lives" Sheol has a 100% chance to spawn. You could also get lucky and obtain the item WE NEED TO GO DEEPER which if used in The Womb II, will skip the fight with Mom's heart and instantly take you to Sheol. Sheol consists of mostly boss rooms so make sure your character has a decent build.
Satan can prove to be difficult if you lack DMG to burst him down quickly. The fight features a three phase boss battle that will always play out as follows:
1. First the boss "The Fallen" will spawn in along with two Kamikaze leeches. once the boss has gone down to half HP, it will split into two. After "The Fallen" is defeated then Satan will spawn in phase two.
2. Satan will have four set patterns that you will have to get used to in order to defeat him. 1) Projectictiles that move to the left and right of the room. 2) brimstone laser down the middle. 3) Homing Brimstones from his hands. 4) Scattering shots similar to Gurdy's attack from his mouth directed at Isaac.
3. Satan will begin to stomp around similar to Mom's Foot, but much quicker. The second foot will come soon after the first one. Two Kamikaze leeches will spawn as well and will continuously spawn another after one of the leeches is defeated.
After defeating Satan's Final form touch the Chest to unlock the achievement.
