The Path to the binding of isaac repentance dead god
Achieving the binding of isaac repentance dead god is the ultimate milestone for any player. This achievement represents 100% completion of the Repentance expansion, requiring the player to unlock every character, complete every challenge, earn every completion mark on Hard Mode, and physically touch every item at least once during a run.

Character Mastery and Completion Marks
To reach the binding of isaac repentance dead god, you must complete the "Post-it Note" for every character. Each note has 12 marks (10 for standard bosses, one for Greedier mode, and one for Boss Rush).

- Tainted Lilith: High damage whip attack.
- Azazel: Flight and mini-brimstone for fast clears.
- Tainted Judas: Dark Arts provides invincibility and damage.
- Isaac (with D6): Best item control in the game.
High-Execution Challenges
- Tainted Lost: No Holy Mantle; any hit is lethal.
- Jacob & Esau: Managing two hitboxes simultaneously.
- Tainted Jacob: Avoiding Dark Esau while clearing rooms.
- Tainted Lazarus: Managing two separate item builds.
| Boss Mark | Requirement / Route | Major Unlock Example |

| Mega Satan | Use Key Pieces in Chapter 6 | Apollyon (Character) |
| Hush | Defeat It Lives! under 30:00 | Maw of the Void |
| Delirium | Enter The Void portal | Spindown Dice (T. Isaac) |
| Mother | Alternate Path (Corpse II) | Jacob & Esau (Characters) |
| The Beast | The Ascent / Home | C Section (Lilith) |
When playing as Tainted Keeper, use the fading coins to buy every item in the shop. This character is one of the fastest for filling out the item collection grid because of his high purchasing power.
Essential Item Tier List for Completion
Your ability to secure the binding of isaac repentance dead god depends heavily on your knowledge of item synergies. Some items are "run-winners" that can carry even the weakest characters through the final boss gauntlets.
| Tier | Item Name | Effect Summary | Why It Matters |
|---|---|---|---|
| S | Sacred Heart | Multiplier + Homing | Massive damage boost for any build |
| S | C Section | Fetus Projectiles | High DPS and excellent synergy scaling |
| S | Glitched Crown | Cycling Pedestals | Allows you to pick the best of 5 items |
| S | R Key | Restart Run | Allows earning double marks in one run |
| A | Brimstone | Piercing Laser | Essential for room clearing and bosses |
| A | Holy Mantle | 1 Hit Protection | Mandatory for The Lost's survival |
| A | Revelation | Holy Laser + Flight | Defensive utility with offensive power |
Be careful with Tiny Planet or Soy Milk unless you have homing or flat damage upgrades. These can drastically lower your effective DPS and ruin a deep run toward Mother or The Beast.
Fast-Track Progression Steps
If you are starting a fresh save file to reach the binding of isaac repentance dead god, follow these steps to unlock content in the most efficient order.
The Initial Grind
Defeat Mom's Heart 11 times to unlock It Lives! and the permanent paths to the Cathedral and Sheol. During this phase, focus on unlocking characters like Azazel and Cain.
The Polaroid and Negative
Defeat Isaac 5 times and Satan 5 times. This unlocks the photographs required to reach the Chest and Dark Room. This is the time to start completing Hard Mode marks for your favorite characters.
The Secret Exit
Defeat Hush 3 times to unlock the Alternate Path. This grants access to Downpour, Mines, and Mausoleum, leading to the Mother fight in the Corpse.
The Ascent and Tainted Characters
Defeat Mother once to unlock the Strange Door in Depths II. Use a teleport (The Fool) after the Mom fight to open the door and begin the Ascent to Home. Use the Red Key in the hallway closet to unlock Tainted Characters.
The Final Collection
Once all completion marks are done, use characters like Tainted Isaac or Tainted Cain to find any missing items. You must touch every item to trigger the final achievement.
Do not forget to donate to the Greed Machine. Reaching 879 coins gives The Lost the Holy Mantle, and 1,000 coins unlocks the Keeper. This is best done by rotating different characters to keep the jam percentage low.
