  • oWoD Dice Probability chart

    Ohai,

    Created with the little application I mentioned here, this is a spreadsheet chart of WoD dice success, failure and botch probability percentages, along with the average successes per roll:

    Spreadsheet Link

    The format is Success% / Failure% / Botch% (avg. successes)

    I hope some find it to be of use. The percentages are somewhat rounded to the first decimal, and are all based on the averages of 100-million rolls per difficulty and dice amount. Difficulty goes up to 9. The second table beneath the first is for specialty-rolls.

    The spreadsheet is color-coded to highlight the most common difficulty and dice amounts, as well as the 10-dice barrier.

    Enjoy!

    Oh! I can see this being very useful when I'm assigning difficulty to specific tasks. Thank you!

      That was the intention behind it
      It's more often than not the storyteller who struggles to figure out how demanding or easy a certain roll might be, and might have trouble getting just the right challenge set up for a task.

      Glad you like it!

        I got one better for you. Here's a small program that will calculate dice pools for up about ~15 dice. It can do more but it will take a long while, too lazy to switch to another language. This uses an equation to calculate chances. No estimations.

          I have this problem with players i know saying ridiculous things like "the more dice i roll, the higher the likelihood i'll fail or botch" and every time i hear it my brain breaks a little. They came from a group who play OWOD with NWOD 1's rules. This is spectacular.

              Thanks for this thread. I've done the math for all cases up to 20 dice, in an Excel spreadsheet. While it's true that the probability of a botch can go up in certain conditions, like at difficulty 9 when you go from 1 to 2 to 3 dice, at the same time the odds of success are rising faster, and there are no conditions where the odds of a botch are higher than or rising faster than the odds of a success. The odds of success, on the other hand, will always rise, in all cases, when you roll more dice. The absolute botch-happiest condition is when the difficulty is 10 and you're rolling 6 dice, but even at that point the odds of success are over 46% and the odds of a botch are under 27%.

              Botch happens, but it's never likely.
