## Are d100 dice fair?

They **are not fair**, they cannot be made fair, and they do not produce the same probabilities as rolling 2d10. A d10 is a pentagonal trapezohedron, which is a symmetrical fair die. Even an imperfect d10 is far more fair than a d100 can be, due to the limits of design.

## When would you roll a d100?

Most uses of a d100 are for a DM

**When a character mixes two potions together**, you can roll on the Potion Miscibility table. If more than two are combined, roll again for each subsequent potion, combining the results. Unless the effects are immediately obvious, reveal them only when they become evident.

## How do you roll a 10 on a d100?

Before rolling, choose one of the two **dice to be your “tens” digit**. Roll them, then arrange them in order (just like you were writing it down – tens to the left of ones). Read the number, that’s your answer. If you get a 0 in the tens spot, it means you rolled under 10.

## What is a 1 on a d100?

TREAT THE d10 THE SAME WAY YOU’VE ALWAYS TREATED IT.

You can’t roll a zero; a 00-0 roll would be a 10. **A 00-1 would be a 1**.

## Why does a d10 have a 0?

The one with two digits is just telling you the tens digit, and the one with one digit is the ones digit. If you’re rolling only that die with 0, 10, 20, etc., then a 10 = a 1 and the 00 = a 10. 0 or 00 on a **d10 just means the highest number**.

## How do you roll for divine intervention?

Divine Intervention

If you roll a number equal to or lower than your Cleric level, your **deity intervenes**. The DM chooses the Nature of the intervention; the Effect of any Cleric spell or Cleric domain spell would be appropriate. If your deity intervenes, you can’t use this feature again for 7 days.

## How do you read dice rolls?

The first die represents the tens digit, and the second die the ones digit. For example, a roll of 1 followed by a roll of 5 will give a total of 15, while a roll of 3 followed by a roll of 6 will give a total of 36. The average result of the D66 is 38.5, and the standard deviation about 17.16.
