I should probably try to clarify with an example. If you have "Chaos
rank" at 5 on this chart, and you look at the "Likely" result, you get a
Target Number of 75 or lower. Going to CR 4 would give you TN 55
instead. Basically I'd like to have it roll the d100, ask me the CR and
probability, then interpret the result. Hrm, well, if take a d100 roll and think of the 10s position as the first axis, and the 1s position as the other axis, you'd still have the equivalent of a grid in a one dimensional array. Example table: Table Value ♦ Equivalent 2d10 of Probability / Chaos 1 ♦ 0, 1 2 ♦ 0 , 2 ~~~~~~~~ (skipping a few for brevity sake) 24 ♦ 2, 4 25 ♦ 2, 5 ~~~~~~~~ (skipping a few for brevity sake) 98 ♦ 9, 8 100 ♦ 0, 0 The table data for each value would be set by you to the appropriate Target Number for that result. If Chaos and Probability are Random: Macro wise, this could then be represented as [[ ( 1d100 - 1t[MythicFate] )>0 ]] , which is to say, roll a 1d100, subtract the result of your chaos/probability random roll from it, and declare success if the 1d100 is greater than or equal to zero. If chaos and probability aren't random, using a table gets tedious, but only has to be setup once. You can set your table up with tokens (which can be very simple images for MSPaint or something that illustrate the result) You would then place the table token on the tabletop by rolling "Token" once and give players Control of it. To "lookup" the target number, they would then Right-Click the table token and select "Multi-Sided" and "Choose Side". The token will then change appearance to the target number image. Your macro would then look like [[ ( 1d100 - ?{What is the Target Number?|0} )>0 ]] which asks the player to type in the Target Number from the table image, subtracts if from a 1d100, and returns Success if its greater than zero. *** Depending on whether or not you're dealing with the Exceptional Yes, or Exceptional No, you may want to take out the >0 aspect and just have the result displayed in chat so you can see the actual roll easier.
