If anyone has worked with the FASA Trek sheets or something similar on Roll20, I could use a bit of advice. The character sheets seem to have an abilities section that allows one to insert attributes and "macros," presumably which would work in conjunction to determine the success of a roll to use said ability. If you've worked directly with that, could anyone explain how that might work? If it sounds similar to something with a different sheet, would anyone be willing to take a guess?
