An old dice system, is there a way to replicate it?

Forever ago, there was a dice system that used specific values to indicate successes. It went something like: 1-14 = 0, 15-19=1, 20-24=2, 25-29=3, 30-34=4, 35-39=5 It went on and on from there, utilizes 2D, 3D, 4D... is there any way to set up a code to read those values, like to set those tables to be read depending on what is rolled?

Yup, a rollable table, with resutls 0, 1, 2, 3 and so on, with weights for those results being 14, 5, 5, 5 and so on, and then rolling that table to get a result, and using that result for another dice roll, so you roll (1t[table name])d6 or what ever.

The rollable table approach is a lot trickier if the die roll uses variable numbers of dice and modifiers. In fact, its not possible - you'd need a different tale for each combination of dice and modifier If the roll is as described above, that's pretty easy to do with a standard dice roll, and the floor function. Something like: /roll {floor((2d10+15)/5)-2,0d0}kh1 Replace 2d10+15 with whatever your roll is, like 4d10+@{selected|atrribute} or whatever

Thank you both a ton.
