Dice And Notation

In Obscured, we use various dice, with the 2_ON_D10 (two ten-sided dice) being the primary set for most rolls. The roll outcome is the sum of the values on both dice (2_ON_D10), where a roll of 0 or 00 represents a 10. This means the lowest possible roll is 2, and the highest is 20. Additionally, the system uses other common RPG dice, including:

D4 four-sided dice

D6 six-sided dice

D8 eight-sided dice

D10 ten-sided dice

D12 twelve-sided dice

D20 twenty-sided dice

D10D10 one-hundred-sided dice

Throughout this guide, these symbols represent the type of dice needed. When a roll requires more than one die, the number of dice is indicated at the center of the symbol. For instance, three four-sided dice are denoted as 3_ON_D4.

High-level games may require multiple dice at once. While using an electronic roller for damage rolls is convenient, it's not a necessity. You can always keep rolling your dice and adding up the results!

Why 2_ON_D10 (two ten-sided dice)?

When rolling a single die, each potential outcome, whether the best, worst, or average, has an equal probability. For a D20 (twenty-sided die), each value has a 5% chance. However, in real-world scenarios, average outcomes are often more likely than extremes. Rolling 2_ON_D10 (two ten-sided dice) mirrors this reality, offering a 10% chance of rolling the average value of 11, with the probability reducing by 1% for each step away from this average. This approach results in a more normal distribution, providing more predictable and realistic outcomes.

Moreover, this structure ensures that any shift in the average roll has a more impactful and consistent effect. For instance, a +2 in our system effectively shifts the average, meaning players proficient in a particular skill will consistently exhibit that proficiency, much like in real-world contexts.
