|---|---|---|---|
| S | Isaac | Normal | The D6 allows for incredible item control and rerolls. |
| S | Azazel | Normal | High early damage and flight make for fast, easy wins. |

For Beginners
Magdalene and Cain offer high health and high luck, making early floors much more forgiving.

Eden starts with completely random items and stats, ensuring no two runs are ever the same.
Step-by-Step Unlock Roadmap
Progression in the binding of isaac repentance switch is non-linear. To reach the "Dead God" achievement, you must follow a specific sequence of victories to unlock the true endings.
The Mom Cycle
Defeat Mom in the Depths to unlock the Womb. You must defeat Mom's Heart 11 times to unlock It Lives!, which opens the permanent paths to the Cathedral and Sheol.
Polaroid & Negative
Defeat Isaac (Cathedral) 5 times to unlock The Polaroid. Defeat Satan (Sheol) 5 times to unlock The Negative. These items are required to enter the Chest and Dark Room respectively.
The Secret Exit
Defeat Hush 3 times. This unlocks the Alternate Path (Downpour, Mines, Mausoleum). This path is significantly harder but necessary to reach the Mother boss.
The Ascent
After defeating Mother once, you can find a "Strange Door" in Depths II. Use a teleport (The Fool card) after the Mom fight to open it and begin the Ascent toward the Home floor and The Beast.
Every major boss yields a "Completion Mark" on a character's post-it note. Hard Mode is recommended because it grants both the Normal and Hard versions of the unlock simultaneously.

Final Boss Strategies and Routes
The endgame of the binding of isaac repentance switch features several "superbosses" with unique mechanics and armor systems that limit how much damage they can take in a single hit.
Hush (Blue Womb)
- Access: Beat It Lives! under 30 minutes.
- Strategy: Focus on dodging the "Continuum" tears that wrap around the screen. Stand in the safe lanes and don't panic.
Delirium (The Void)
- Access: Random portal after major bosses (100% after Hush).
- Strategy: The most unpredictable boss. High movement speed and "Holy Mantle" protection are vital as he teleports constantly.
Mother (The Corpse)
- Access: Complete the Knife Piece puzzle in the Alt Path.
- Strategy: A two-phase fight. In phase two, stay toward the bottom of the screen to avoid her sweeping hand attacks.
The Beast (Home)
- Access: Complete the Ascent and defeat Dogma.
- Strategy: A side-scrolling gauntlet. Focus on the Ultra Horsemen first. Use the "Dogma" item's flight to navigate the fire rings.
Defeating The Beast as every character (including Tainted versions) is required for the final ending. Each win unlocks a unique item that will appear in future runs of the binding of isaac repentance switch.
Q: How do I unlock Tainted characters on Switch?
During the 'Ascent' to Home, leave a trinket in any Treasure or Boss room. It will turn into a 'Cracked Key' during the reverse climb. Use this key on the red outline in the hallway outside Mom's room in Home.
Q: What is the best way to farm Greed Mode?
Play as Lilith. Her 'Box of Friends' active item allows her to stack multiple Incubus familiars during the wave sequences, making her nearly unstoppable in Greed and Greedier mode.
Q: Why can't I find the Secret Exit?
You must defeat Hush three times on your save file before the secret exit doors (Downpour/Dross) will start appearing after boss fights.
Q: Is there co-op in the Switch version?
Yes, the binding of isaac repentance switch supports up to 4-player local co-op. Players can join as full characters, sharing the item pool and resources.
