Then I can't help you. I said "quick and dirty"

But I think the mechanic is simple enough. If getting a 1, roll a D6. Keep on rolling the D6 until it doesn't end up as a one. First D6 is -5 + D6, second is -10 + D6, third is -15 + D6, and so on.

Getting a 6 will go back to the 1 of the former dice, closing the gap some open ended roll system tend to have. The D6 also gives the advantage of ending up on an incremental of fives, making the math during play a bit easier.

The odds of a 3D20L, with this addon, to get a -6 is about 1,6%, while that untrained shooter with 2D20H as a 0,03% chance.

I like it. However I have a few questions. If a 5d20 produces 2 or more 1 would you get 2 or more chances on the d6 tree. I did not think your graph presented that, but was not sure.

I was also thinking of using different dice like a d12 for 5d20, a d10 for 4d20, a d8 for 3 d20, etc.

If we consider sub 1 results to be unusually superior, I like what the graph shows
