What's the maximum number of dice you're likely to roll? If it's the individual rolls you're after, rather than the total, you can do this with a Query: ?{How many dice?|2,[[1d20+?{Modifier|5}]] [[1d20+?{Modifier}]]| 3,[[1d20+?{Modifier|5}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]]| 4,[[1d20+?{Modifier|5}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]]| 5,[[1d20+?{Modifier|5}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]]| 6,[[1d20+?{Modifier|5}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]] [[1d20+?{Modifier}]]} And extend it as far as you need. As long as you have a reasonable limit on how many you're rolling it's easy enough to extend. You can pretty it up with a template too, depending on what sheet you''re using. If you only need the total, the second one GiGs suggested is the easiest way.
