using the “unique” roll condition (‘U’), you can roll a pool of dice that will reroll repeat values. (Details in the documentation here). If you have a die with the names of your players, you can roll an expression which will output their names in a random order like this:
if you don’t want to make a die or are in a rush, number your players and then the expression “4d4TiU” can decide what order they go in. This rolls 4d4, converts the dice values to individual text values (so they don’t get summed) and then applies the ‘unique’ condition so that duplicates get rerolled.
When you have an expression you’re happy to use, you can save it to your dice bag and roll it with a single hotbar click/tap whenever you need it.
Hope that helps! :)
