The D20 is a powerful and often game-breaking item in The Binding of Isaac, renowned for its ability to transform the landscape of a run through its unique rerolling capabilities. However, unlocking it requires a specific feat. This article will provide you with a detailed guide on how to unlock the D20 and answer some frequently asked questions to enhance your understanding of this coveted item.
How to Unlock the D20
The D20 is unlocked by completing a very specific challenge: you must defeat the boss of The Chest as Isaac. This means you need to successfully navigate the levels of the game, culminating in a victory against the final boss located in The Chest. Once you defeat the boss, the D20 will be permanently unlocked. From that point forward, the D20 will be added to the item pool and can be found during your runs in the game.
It’s important to note that you must be playing as the base character, Isaac, for this unlock to occur. Playing as other characters will not count towards unlocking the D20.
The Power of the D20
What Does The D20 Do?
Upon activation, the D20 rerolls all pickups present in the current room. This includes:
- Bombs
- Coins
- Hearts
- Keys
- Pills
- Tarot Cards
- Trinkets
- Chests
The D20 can even transform un-detonated Troll Bombs into other pick-ups. This can be a huge advantage, as it can turn potentially dangerous situations into opportunities for resource gain. It’s also important to note that using the D20 will not reroll items within pedestals, only the above-mentioned pickups.
The D20 in Combat
The D20’s rerolling ability isn’t solely for resource management; it can also be advantageous in combat. For example, using the D20 can transform a boss’s dangerous troll bombs into a variety of useful pick-ups mid-fight. If you’re playing against the Four Horsemen, using the D20 on War’s troll bombs can provide a major boost.
Golden Trinkets and the D20
If you reroll a Golden Trinket with the D20, the resulting pickup will have the golden effect applied to it. If this results in another trinket, the effect works as a normal golden trinket, otherwise, the gold effect does nothing and will disappear upon leaving and reentering the room. It is important to consider your environment when using the D20 with Golden Trinkets.

Rolling a 20 on a D20 in tabletop games like Dungeons & Dragons is considered a “natural 20” or “nat 20” and is usually an automatic success for whatever task the player’s character is attempting, whether it is an attack roll, a saving throw, or an ability check.
5. What does a 1 Dice Room do?

9. Is the D20 better than the D6?
The D20 is more situational, offering more potential for game-breaking moments, while the D6 is more readily available as Isaac and useful on every floor. D20 usage is usually limited to one-floor uses(mostly in the Arcade). This makes the D6 generally preferred for its consistent item-rerolling.

12. How do I find super secret rooms?
To locate a Super Secret Room, try bombing walls that do not share a perimeter with another room, except for regular secret rooms. Generally, Super Secret Rooms are located on the edge of the map.
13. What does a 3 Dice Room do?
The Dice Room with three (3) dots rerolls all collectibles on the floor, this includes chests, pickups, and trinkets! The Dice Room with four (4) dots rerolls almost all the items on the floor, much like the D6, except items in the Shop and Angel/Devil rooms.
14. What does a 2 in a Dice Room do?
A Dice Room with a two (2) dot activates the D20 effect – rerolling every pickup (Hearts, Coins, Keys, Bombs, etc.) in the room. It is possible to simply ignore the die and pick up the existing pickups.
