Dice Mechanics: Examples

Trinity

         The White Wolf games Trinity, Aberrant, and Adventure uses a modified version of the Storyteller mechanic. There is no longer a varying target number. Instead, the target number is always 7. Difficulty is represented by requiring more successes. The following table shows the probability of various die results using this system.

# of dice Chance of N Successes Avg #S
BotchFail 1 2 3 4 5
1d10%50%40% 0% 0% 0% 0% 0.4

10d 1% 0% 4%12%22%25%21% 4.0

         Botching has two features: first that the chance goes up slightly with dice before dropping. Second, that the chance of botching relative to normal failure goes up with dice. i.e. If you are very good at an action, if you fail you are very likely to botch.
