## 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 d100 with a 2d10?

You can also use this as a standard d10 just by using only the tens digit on each face. In any event, once you’ve decided which die is which digit, roll them both and combine them to get the result. If you’re rolling 2d10, then multiply the tens die’s result by 10 and then add them together.

## 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.
