Unique Rolls on Table/Story Entries
TLDR: If you are rolling on the same table multiple times, using a story page/generator, is there any way to make each roll unique so the story/generated page doesn't have a duplicate result (off the same table)?
Explanation:
I'm making a Tarroka deck. I don't own CoS so I'm not sure if there's one already made in there. I am going to be using this in my own Ravenloft adventure, as well as a character backstory generator. I want to automate a 'reading' so I can hit one button and generate a total of seven cards. Three for the past, one for present and three for the future (I'll have a different card layout for the character generator/separate generator). When I am 'drawing' the cards, I don't want there to be any duplicates? Is this possible?
Thanks, in advance, for the answers.
