This variant uses a d20 instead of the d%, and does not involve referencing the Master Table. It generates results that are different – but similar – to those that would have resulted from a d% and the Master Table. If you are looking for a system that uses a d20 and the Master Table, check out 20C System.
The first step is to convert your Rank Value to a Rank Score.
| Rank Value | Rank Score |
| 5000+ | 18 |
| 2500-4999 | 17 |
| 1500-2499 | 16 |
| 1000-1499 | 15 |
| 500-999 | 14 |
| 250-499 | 13 |
| 150-249 | 12 |
| 100-149 | 11 |
| 75-99 | 10 |
| 50-74 | 9 |
| 40-49 | 8 |
| 30-39 | 7 |
| 20-29 | 6 |
| 10-19 | 5 |
| 6-9 | 4 |
| 3-5 | 3 |
| 1-2 | 2 |
| 0 | 1 |
When you are asked to roll a d% and consult the Master Table, instead roll a d20, add your rank score, and consult the ACT Table. You also apply any rank shifts from circumstance bonuses or penalties.
| ACT Table | |
| Roll | Result |
| A 'natural 1' | Black |
| A 'natural 20' | Yellow |
| 1-15 | Black |
| 16-20 | Red |
| 21-25 | Blue |
| 26+ | Yellow |
A ‘natural 1’ is when the dice roll (unmodified by your rank score) is 1.
A ‘natural 20’ is when the dice roll (unmodified by your rank score) is 20.
