If this option already exists in Roll20, I'm unable to find it.
My suggestion is to provide a different way for doing macros able to account for margin of success against a Target Number -the current macro accounting for successes against a Target Number for individual dice works only for certain RPG systems.
For instance, GURPS handles margin of success against a Target Number in this way:
- You have a skill at level 12 (the target number).
- Then you have to roll 3d6 and get 12 or less for a success in that skill/attribute roll/self-control roll/whatever.
- If you roll less than 12, the difference is your *margin of success*; and if you roll more than 12, the excess is your *margin of failure.*
I'd like to see a way of handling this rolling against a Target Number, displaying the success or failure of dice rolls (along with their margin of success or failure) in Roll20. This would work for other systems too, like the AD&D 2ed way of rolling against "Non-weapon Proficiencies" (roll the Target Number of less in a d20), for instance.
This could be addressed by means of a sort of variation of the current macro formula involving the > and < characters.
The following screenshot of how the Fantasy Grounds II GURPS ruleset handles rolling against Target Numbers is an example of what I'm suggesting:
