Is this a rule from a specific World Book? You could set up a Macro where only 3 Fate dice are rolled instead of 4, and add or subtract 1 because one of your dice is fore-ordained to be that value. So one Macro is /r 3df+1+(Skill or other modifiers such as Boosts) and the other Macro is /r 3df-1+(Skill or other modifiers such as Boosts) A few years ago I went nuts with techniques for Fate Macro formulas (first started by Nick T., my first Fate GM), where I had to click a particular Token first, but these techniques have been superseded by in-sheet rolls on the Fate character sheet: <a href="https://wiki.roll20.net/Fate_Core" rel="nofollow">https://wiki.roll20.net/Fate_Core</a> You can also write dice-rolls in an in-line form with double square-brackets: "The roll: [[3df+1+?{Skill?|0}]]" It pauses to ask you for a Skill level (if you enter nothing, it defaults to 0) and displays one number. To get the breakdown, you have to touch that number with your mouse.
