Tricky Dice Roll macro

I have a homebrew system that uses the following dice roll rule: Roll 1d6-1d6 and add Skill If either Die is a 6, don't change the rolled number, but it is a Special result. Is there a way in roll20 to have a macro which shows the result, and adds "Special" to the output when either die is a 6?

Nope, if the critical color coding doesn't work for you, this would need an API

Actually, if you are using a custom character sheet in your game, you could use a Roll Template and that (if coded properly) would also allow you to do that without the API.

Scott, I overlooked using the critical colour coding. But I'd like to have the dice result use inline rolls, so I'm not sure how to display that with the reult all on one line. (Using /roll does show the colour coding, but splits it across several lines). Finderski, I am intrigued by the idea of using a rolltemplate. I have set them up before, but I'm not sure how to do this particular roll with it. Since I need to subtract 1 die from the another, but also look at them independently to see if they got a six. In rolltemplates as far as i know, you cant perform arithmetic. So I could have a roll template if statement that looks at the reuslt of the first die, then looks at the result of the second die, but I'm not sure how to then subtract one from the other within the rolltemplate. Can you help me figure out how to do this roll in a rolltemplate?

[[1d6-1d6]] would give you critical color coding. If it is green or red highlighted, then mouse over to see what was what.

Scott, thanks. Also, I figured out how to do it the rolltemplate way too, so thanks for pointing me in that direction Finderski. I had completely overlooked the RollwasCrit and rollwasFumble conditionals.

[[({0,floor(1-abs([[1d6]]-6))}dl1)*(T-F) +F]] This will result in a 0 unless it is a 6, then it will result in a 1

Thanks Bob, but I actually need to know the value on the dice as well as whether one of them shows a 6.  The critical colour coding, and the rolltemplate approach give me what i need.
